Warning This equipment must be installed and maintained by service personnel as defined by AS/NZS 3260. Incorrectly connecting this equipment to a general purpose outlet could be hazardous. The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the front door is open.
Warning The ONS 15454 is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock, key, or other means of security. A restricted access area is controlled by the authority responsible for the location.
Warning Mount ONS 15454 racks on concrete or other non-combustible surfaces only.
Caution Unused card slots should be filled with a blank faceplate (Cisco P/N 15454-BLANK). The blank faceplate ensures proper airflow when operating the ONS 15454 without the front door attached, although Cisco recommends that the front door remain attached.
Note The ONS 15454 is designed to comply with GR-1089-CORE Type 2 and Type 4. Install and operate the ONS 15454 only in environments that do not expose wiring or cabling to the outside plant. Acceptable applications include Central Office Environments (COEs), Electronic Equipment Enclosures (EEEs), Controlled Environment Vaults (CEVs), huts, and Customer Premise Environments (CPEs).
1.1 Installation Overview
When installed in an equipment rack, the ONS 15454 assembly is typically connected to a fuse and alarm panel to provide centralized alarm connection points and distributed power for the ONS 15454. Fuse and alarm panels are third-party equipment and are not described in this documentation. If you are unsure about the requirements or specifications for a fuse and alarm panel, consult the user documentation for the related equipment. The front door of the ONS 15454 allows access to the shelf assembly, fan-tray assembly, and cable-management area. The backplanes provide access to alarm contacts, external interface contacts, power terminals, and BNC/SMB connectors.
Warning The ONS 15454 relies on the protective devices in the building installation to protect against short circuit, overcurrent, and grounding faults. Ensure that the protective devices are properly rated to protect the system, and that they comply with national and local codes.
Warning Incorporate a readily-accessible, two-poled disconnect device in the fixed wiring.
You can mount the ONS 15454 in a 19- or 23-inch rack. The shelf assembly weighs approximately 55 pounds with no cards installed. The shelf assembly includes a front door for added security, a fan tray module for cooling, and extensive cable-management space.
ONS 15454 optical cards have SC connectors on the card faceplate. Fiber optic cables are routed into the front of the destination cards. Electrical cards (DS-1, DS-3, DS3XM-6, and EC-1) require electrical interface assemblies (EIAs) to provide the cable connection points for the shelf assembly. In most cases, EIAs are ordered with the ONS 15454 and come pre-installed on the backplane. See the "Backplane Access" section for more information about the EIAs.
The ONS 15454 is powered using -48V DC power. Negative, return, and ground power terminals are accessible on the backplane.

1.3 Rack Installation
Warning To prevent the equipment from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 131°F (55°C). To prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance around the ventilation openings.
The ONS 15454 is easily mounted in a 19- or 23-inch equipment rack. The shelf assembly projects five inches from the front of the rack. It mounts in both EIA-standard and Telcordia-standard racks. The shelf assembly is a total of 17 inches wide with no mounting ears attached. Ring runs are not provided by Cisco and may hinder side-by-side installation of shelves where space is limited.
The ONS 15454 measures 18.5 inches high, 19 or 23 inches wide (depending on which way the mounting ears are attached), and 12 inches deep (47 by 48.3 by 30.5 cm). You can install up to four ONS 15454s in a seven-foot equipment rack. The ONS 15454 must have 1 inch of airspace below the installed shelf assembly to allow air flow to the fan intake. If a second ONS 15454 is installed underneath the shelf assembly, the air ramp on top of the lower shelf assembly provides the air spacing needed and should not be modified in any way. Figure 1-1 shows the dimensions of the ONS 15454.
Note The 10 Gbps compatible shelf assembly (15454-SA-10G) and fan-tray assembly (15454-FTA3) are required with the ONS 15454 XC10G, OC-192, and OC-48 any slot (AS) cards.
Warning The ONS 15454 should be installed in the lower rack position or mounted above another ONS 15454 shelf assembly.
Warning The ONS 15454 must have 1 inch of airspace below the installed shelf assembly to allow air flow to the fan intake. The air ramp (the angled piece of sheet metal on top of the shelf assembly) provides this spacing and should not be modified in any way.
Figure 1-1 Cisco ONS 15454 dimensions
1.3.1 Reversible Mounting Bracket
Caution Use only the fastening hardware provided with the ONS 15454 to prevent loosening, deterioration, and electromechanical corrosion of the hardware and joined material.
Caution When mounting the ONS 15454 in a frame with a non-conductive coating (such as paint, lacquer, or enamel) either use the thread-forming screws provided with the ONS 15454 shipping kit, or remove the coating from the threads to ensure electrical continuity.
The shelf assembly comes preset for installation in a 23-inch rack, but you can reverse the mounting bracket to fit the smaller, 19-inch rack. The following steps describe how to reverse the shelf assembly mounting bracket to fit a 19-inch rack.
Procedure: Reverse the Mounting Bracket to Fit a 19-Inch Rack
Step 1 Remove the screws that attach the mounting bracket to the side of the shelf assembly.
Step 2 Flip the detached mounting bracket upside down.
Text imprinted on the mounting bracket will now also be upside down.
Step 3 Place the widest side of the mounting bracket flush against the shelf assembly (see Figure 1-2).
The narrow side of the mounting bracket should be towards the front of the shelf assembly. Text imprinted on the mounting bracket should be visible and upside down.
Step 4 Align the mounting bracket screw holes against the shelf assembly screw holes.
Step 5 Insert the screws that were removed in Step 1 and tighten them.
Step 6 Repeat the procedure for the mounting bracket on the opposite side.
Figure 1-2 Reversing the mounting brackets (23-inch position to 19-inch position)
1.3.2 Mounting a Single Node
Mounting the ONS 15454 in a rack requires a minimum of 18.5 inches of vertical rack space (and one inch for air flow). To ensure the mounting is secure, use two to four #12-24 mounting screws for each side of the shelf assembly. Figure 1-3 shows the rack mounting position for the ONS 15454.
Figure 1-3 Mounting an ONS 15454 in a rack
Two people should install the shelf assembly; however, one person can install it using the temporary set screws included. The front door can also be removed to lighten the shelf assembly (see the "Remove the Front Door" procedure).
Note If you are installing the fan-tray air filter using the brackets provided, mount the brackets on the bottom of the shelf assembly before installing the ONS 15454 in a rack.
Procedure: Mount the Shelf Assembly in a Rack (One Person)
Step 1 Ensure that the shelf assembly is set for the desired rack size (either 19 or 23 inches).
Step 2 Using the hex tool that shipped with the assembly, install the set screws into the screw holes that will not be used to mount the shelf.
Step 3 Lift the shelf assembly to the desired rack position and set it on the set screws.
Step 4 Align the screw holes on the mounting ears with the mounting holes in the rack.
Step 5 Install one mounting screw in each side of the assembly.
Step 6 When the shelf assembly is secured to the rack, install the remaining mounting screws.
Note Use at least one set of the horizontal screw slots on the ONS 15454 to prevent future slippage.
Step 7 Remove the temporary set screws.
Procedure: Mount the Shelf Assembly in a Rack (Two People)
Step 1 Ensure that the shelf assembly is set for the desired rack size (either 19 or 23 inches).
Step 2 Lift the shelf assembly to the desired position in the rack.
Step 3 Align the screw holes on the mounting ears with the mounting holes in the rack.
Step 4 While one person holds the shelf assembly in place, the other person can install one mounting screw in each side of the assembly.
Step 5 When the shelf assembly is secured to the rack, install the remaining mounting screws.
Note Use at least one set of the horizontal screw slots on the ONS 15454 to prevent future slippage.
1.3.3 Mounting Multiple Nodes
Most standard seven-foot racks can hold four ONS 15454s and a fuse and alarm panel. However, unequal flange racks are limited to three ONS 15454s and a fuse and alarm panel or four ONS 15454s and a fuse and alarm panel from an adjacent rack.
If you are using the bottom brackets to install the fan-tray air filter, you can install three shelf assemblies in a standard seven-foot rack. If you are not using the bottom brackets, you can install four shelf assemblies in a rack. The advantage to using the bottom brackets is that you can replace the filter without removing the fan tray.
Procedure: Mount Multiple Shelf Assemblies in a Rack
Note The ONS 15454 must have one inch of airspace below the installed shelf assembly to allow air flow to the fan intake. If a second ONS 15454 is installed underneath a shelf assembly, the air ramp on top of the bottom shelf assembly provides the desired space. However, if the ONS 15454 is installed above third-party equipment, you must provide a minimum spacing of one inch between the third-party shelf assembly and the bottom of the ONS 15454. The third-party equipment must not vent heat upward into the ONS 15454.
Step 1 Install the fuse and alarm panel in the top space.
Step 2 Mount the first ONS 15454 directly below the fuse and alarm panel.
Step 3 Repeat the procedure with the third and fourth ONS 15454s.
1.3.3.1 Four Node Configuration
You can link multiple ONS 15454s using their OC-N cards (i.e., create a fiber-optic bus) to accommodate more access traffic than a single ONS 15454 can support. For example, if you need to drop more than 112 DS-1s or 96 DS-3s (the maximum that can be aggregated in a single node), you can link the nodes but not merge multiple nodes into a single ONS 15454. You can link nodes with OC-12 or OC-48 fiber spans as you would link any other two network nodes. The nodes can be co-located in a facility to aggregate more local traffic.
Figure 1-4 shows a four-shelf node setup. Each shelf assembly is reorganized as a separate node in the ONS 15454 software interface (Cisco Transport Controller [CTC]), and traffic is mapped using CTC cross-connect options. In the figure, each node uses redundant fiber-optic cards. Node 1 uses redundant OC-N transport and OC-N bus (connecting) cards for a total of four cards, with eight free slots remaining. Nodes 2 and 3 each use two redundant OC-N bus cards for a total of four cards, with eight free slots remaining. Node 4 uses redundant OC-12 bus cards for a total of two cards, with ten free slots remaining. The four node example presented here is one of many ways to set up a multiple-node configuration. See " "SONET Topologies" for more information about multiple-node configurations.
Figure 1-4 A four-shelf node configuration
1.3.3.2 ONS 15454 Bay Assembly
The Cisco ONS 15454 Bay Assembly simplifies ordering and installing the ONS 15454 because it allows you to order shelf assemblies pre-installed in a seven-foot rack. The Bay Assembly is available in a three- or four-shelf configuration. The three-shelf configuration includes three ONS 15454 shelf assemblies, a pre-wired fuse and alarm panel, and two cable-management trays. Optional fiber channels can be ordered. The four-shelf configuration includes four ONS 15454 shelf assemblies and a pre-wired fuse and alarm panel. Optional fiber channels can be ordered. A four shelf ONS 15454 Bay Assembly is shown in Figure 1-5.
Figure 1-5 A four-shelf ONS 15454 Bay Assembly
1.4 Front Door Access
The Critical, Major, and Minor alarm LEDs visible through the front door indicate whether a Critical, Major, or Minor alarm is present anywhere on the ONS 15454. These LEDs must be visible so technicians can quickly determine if any alarms are present. You can use the LCD to further isolate alarms. See Chapter 10, "Alarm Monitoring and Management" for more information.
This section tells you how to access ONS 15454 equipment in the front compartment. The ONS 15454 features a locked door to the front compartment. A pinned Allen key that unlocks the front door ships with the ONS 15454. A button on the right side of the shelf assembly releases the door. The front door provides access to the shelf assembly, cable-management tray, fan-tray assembly, and LCD screen ( Figure 1-8).
You can remove the front door of the ONS 15454 to provide unrestricted access to the front of the shelf assembly. An erasable label ( Figure 1-6) is pasted on the inside of the front door. You can use the label to record slot assignments, port assignments, card types, node ID, rack ID, and serial number for the ONS 15454.
Figure 1-6 The front-door erasable label
Note The front door label also includes the Class I and Class 1M laser warning shown in the laser warning on the front-door label ( Figure 1-7).
Figure 1-7 The laser warning on the front-door label
Procedure: Open the Front Cabinet Compartment (Door)
Note The ONS 15454 has an ESD plug input and is shipped with an ESD wrist strap. The ESD plug input is located on the outside edge of the shelf assembly on the right-hand side. It is labeled "ESD" on the top and bottom. Always wear an ESD wrist strap and connect the strap to the ESD plug when working on the ONS 15454.
Step 1 Open the front door lock.
The ONS 15454 comes with a pinned hex key for locking and unlocking the front door. Turn the key counterclockwise to unlock the door and clockwise to lock it.
Step 2 Press the door button to release the latch.
Step 3 Swing the door open.
Figure 1-8 The ONS 15454 front door
Procedure: Remove the Front Door
Step 1 Open the door.
Step 2 Lift the door from its hinges at the top left-hand corner of the door ( Figure 1-9).
Figure 1-9 Removing the ONS 15454 front door
1.5 Backplane Access
To access the ONS 15454 backplane, remove the two standard sheet metal covers on each side of the backplane ( Figure 1-10). Each sheet metal cover is held in place with nine 6-32 x 3/8 inch phillips screws.
Figure 1-10 Backplane sheet metal covers
Procedure: Remove the Backplane Sheet Metal Covers
Step 1 To remove the lower backplane cover, loosen the five screws that secure it to the ONS 15454 and pull it away from the shelf assembly.
Step 2 Loosen the nine perimeter screws that hold the backplane sheet metal cover(s) in place.
Step 3 Lift the panel by the bottom to remove it from the shelf assembly.
Step 4 Store the panel for later use. Attach the backplane sheet metal cover(s) whenever EIA(s) are not installed.
1.5.1 Lower Backplane Cover
The lower section of the ONS 15454 backplane is covered by a clear plastic protector, which is held in place by five 6-32 x 1/2 inch screws. Remove the lower backplane cover to access the alarm interface panel (AIP), alarm pin field, frame ground, and power terminals.
Figure 1-11 Removing the lower backplane cover
Procedure: Remove the Lower Backplane Cover
Step 1 Unscrew the five retaining screws that hold the clear plastic cover in place.
Step 2 Grasp the clear plastic cover at each side.
Step 3 Gently pull the cover away from the backplane (shown in Figure 1-11).
1.5.2 Alarm Interface Panel
The AIP is located above the alarm pin field on the lower section of the backplane. The AIP provides surge protection for the ONS 15454. It also provides an interface from the backplane to the fan-tray assembly and LCD. The AIP plugs into the backplane using a 96-pin DIN connector and is held in place with two retaining screws. The panel has a non-volatile memory chip that stores the unique node address (MAC address).
The 5-amp AIP card (73-7665-XX) is required when installing the new fan-tray assembly (15454-FTA3). See the "Install the Fan-Tray Assembly" procedure.
The MAC address identifies the nodes that support circuits. It allows CTC to determine circuit sources, destinations, and spans. The Timing Communication and Control+ (TCC+) cards in the ONS 15454 also read the MAC address to store the node database. If the AIP fails, a MAC Fail alarm displays on the CTC Alarms menu and/or the LCD display on the fan tray will go blank.
Note A blown fuse on the AIP board can cause the LCD display to go blank.
1.6 EIA Installation
Optional EIA backplane covers are typically pre-installed when ordered with the ONS 15454. EIAs must be ordered when using DS-1, DS-3, DS3XM-6, or EC-1 cards. A minimum amount of assembly may be required when EIAs are ordered separately from the ONS 15454. Four different EIA backplane covers are available for the ONS 15454: BNC, High-Density BNC, SMB, and AMP Champ. This section describes each EIA in detail.
EIAs are attached to the shelf assembly backplane to provide coaxial cable connections. EIAs are available with SMB and BNC connectors for DS-3 or EC-1 cards. EIAs are available with AMP Champ connectors for DS-1 cards. You must use SMB EIAs for DS-1 twisted-pair cable installation. You can install EIAs on one or both sides of the ONS 15454 backplane in any combination (in other words, AMP Champ on Side A and BNC on Side B or High-Density BNC on side A and SMB on side B, and so forth).
If you are installing EIAs after the shelf assembly is installed, plug the EIA into the backplane. The EIA has six electrical connectors that plug into six corresponding backplane connectors. The EIA backplane must replace the standard sheet metal cover to provide access to the coaxial cable connectors. The EIA sheet metal covers use the same screw holes as the solid backplane panels, but they have 12 additional 6-32 x 1/2 inch phillips screw holes so you can screw down the cover and the board using standoffs on the EIA board. This section describes each EIA and provides installation procedures.
For EIA replacement procedures, refer to the Cisco ONS 15454 Troubleshooting and Maintenance Guide. For information about attaching ferrites to EIA connectors, see the "Ferrite Installation" section.
1.6.1 BNC EIA
The ONS 15454 BNC EIA supports 24 DS-3 circuits on each side of the ONS 15454 (24 transmit and 24 receive connectors). If you install BNC EIAs on both sides of the shelf assembly, the ONS 15454 hosts up to 48 circuits. The BNC connectors on the EIA supports Trompeter UCBJ224 (75 Ohm) 4 leg connectors (King or ITT are also compatible). You can use BNC EIAs for DS-3 (including the DS3XM-6) or EC-1 cards. Figure 1-39 shows the ONS 15454 with pre-installed BNC EIAs.
To install coaxial cable with BNC connectors, see the "BNC Connector Installation" section.

The second 12 BNC connector pairs correspond to Ports 1-12 for a 12-port card and map to Slot 4 on the shelf assembly. You can install an additional card in Slot 3 as a protect card for the card in Slot 4. Slots 5 and 6 do not support DS-3 cards when BNC connectors are used.
The EIA side marked "B" provides an additional 24 pairs of BNC connectors. The first 12 BNC connector pairs correspond to Ports 1-12 for a 12-port card and map to Slot 14 on the shelf assembly. The BNC connector pairs are marked "Tx" and "Rx" to indicate transmit and receive cables for each port. You can install an additional card in Slot 15 as a protect card for the card in Slot 14. The second 12 BNC connector pairs correspond to Ports 1-12 for a 12-port card and map to Slot 16 on the shelf assembly. You can install an additional card in Slot 17 as a protect card for the card in Slot 16. Slots 12 and 13 do not support DS-3 cards when BNC connectors are used.
When BNC connectors are used with a DS3N-12 card in Slot 3 or 15, the 1:N card protection extends only to the two slots adjacent to the 1:N card due to BNC wiring constraints.
1.6.2 High-Density BNC EIA
The ONS 15454 High-Density BNC EIA supports 48 DS-3 circuits on each side of the ONS 15454 (48 transmit and 48 receive connectors). If you install BNC EIAs on both sides of the unit, the ONS 15454 hosts up to 96 circuits. The High-Density BNC EIA supports Trompeter UCBJ224 (75 Ohm) 4 leg connectors (King or ITT are also compatible). You can use High-Density BNC EIAs for DS-3 (including the DS3XM-6) or EC-1 cards. Figure 1-13 shows the ONS 15454 with pre-installed High-Density BNC EIAs.
To install coaxial cable with High-Density BNC connectors, see the "High-Density BNC Connector Installation" section.
Figure 1-13 A High-Density BNC backplane for use in 1:N protection schemes
The EIA side marked "A" hosts 48 pairs of BNC connectors. Each column of connector pairs is numbered and corresponds to the slot of the same number. The first column (12 pairs) of BNC connectors corresponds to Slot 1 on the shelf assembly, the second column to Slot 2, the third column to Slot 4, and the fourth column to Slot 5. The rows of connectors correspond to Ports 1-12 of a 12-port card.
The EIA side marked "B" provides an additional 48 pairs of BNC connectors. The first column (12 pairs) of BNC connectors corresponds to Slot 13 on the shelf assembly, the second column to Slot 14, the third column to Slot 16, and the fourth column to Slot 17. The rows of connectors correspond to Ports 1-12 of a 12-port card. The BNC connector pairs are marked "Tx" and "Rx" to indicate transmit and receive cables for each port. The High-Density BNC EIA supports both 1:1 and 1:N protection across all slots.
1.6.3 SMB EIA
The ONS 15454 SMB EIA supports AMP 415484-1 75 Ohm 4 leg connectors. You can use SMB EIAs with DS-1, DS-3 (including the DS3XM-6), and EC-1 cards. If you use DS-1 cards, use the DS-1 electrical interface adapter to terminate the twisted pair DS-1 cable from the backplane.
Figure 1-14 shows the ONS 15454 with pre-installed SMB EIAs and the sheet metal cover and screw locations for the EIA.To install SMB connectors, see the "SMB Connector Installation" section.
Figure 1-14 An SMB EIA backplane
The SMB EIA has 84 transmit and 84 receive connectors on each side of the ONS 15454 for a total of 168 SMB connectors (84 circuits).

1.7 Fan-Tray Assembly Installation
The fan-tray assembly is located at the bottom of the ONS 15454 front compartment. The fan tray is a removable drawer that holds fans and fan-control circuitry for the ONS 15454. The front door can be left in place or removed before installing the fan-tray assembly. After you install the fan tray, you should only need to access it if a fan failure occurs or you need to replace or clean the fan-tray air filter.
The front of the fan-tray assembly has an LCD screen that provides slot and port-level information for all ONS 15454 card slots, including the number of Critical, Major, and Minor alarms.
The fan-tray assembly features an air filter at the bottom of the tray that you can install and remove by hand. Remove and visually inspect this filter every 30 days and keep spare filters in stock. See the Cisco ONS 15454 Troubleshooting and Maintenance Guide for information about cleaning and maintaining the fan-tray air filter.
Note The 10-Gbps compatible shelf assembly (15454-SA-ANSI, P/N: 800-19857) and fan-tray assembly (15454-FTA3) are required with the ONS 15454 XC10G, OC-192, and OC-48 any slot (AS) cards.
Caution Do not operate an ONS 15454 without a fan-tray filter. A fan-tray filter is mandatory.
Caution The 15454-FTA3 fan-tray assembly can only be installed in ONS 15454 Release 3.1 and later shelf assemblies (15454-SA-ANSI, 800-19857). It includes a pin that does not allow it to be installed in ONS 15454 shelf assemblies released before ONS 15454 Release 3.1 (15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1, P/N 800-0714915454). Installing the 15454-FTA3 in a non-compliant shelf assembly may result in failure of the alarm interface panel (AIP), which in turn, will result in power loss to the fan-tray assembly.
Note The ONS 15454 Release 3.1 and later fan-tray assembly (15454-FTA3) is not I-temp. To obtain an I-temp fan tray, install the 15454-FTA2 fan-tray assembly in an ONS 15454 Release 3.1 and later shelf assembly (P/N: 800-19857). However, do not install the ONS 15454 Release 3.1 XC10G, OC-192, and OC-48 any slot (AS) cards in the shelf assembly with the 15454-FTA2 fan-tray assembly.
If one or more fans fail on the fan-tray assembly, replace the entire assembly. You cannot replace individual fans. The red Fan Fail LED on the front of the fan tray illuminates when one or more fans fail. For fan tray replacement instructions, see the "Install the Fan-Tray Assembly" procedure. The red Fan Fail LED clears after you install a working fan tray.
Fan speed is controlled by TCC+ card temperature sensors. The sensors measure the input air temperature at the fan-tray assembly. Fan speed options are low, medium, and high. If the TCC+ card fails, the fans automatically shift to high speed. The temperature measured by the TCC+ sensors is displayed on the LCD screen.
Procedure: Install the Bottom Brackets and Air Filter
The shelf assembly ships with bottom brackets that you should use to install the air filter. The bottom brackets consist of two grooved metal pieces that attach to the bottom of the shelf assembly using three screws each. When you use the bottom bracket to install the fan-tray air filter, you do not need to remove the fan-tray assembly to access the air filter. Attach the brackets to the bottom of the shelf assembly before installing the rack.
Although the filter will work if it is installed with either side facing up, Cisco recommends that you install it with the metal bracing facing up to preserve the surface of the filter.
Note If you choose not to install the bottom brackets, install the air filter by sliding it into the compartment at the bottom of the shelf assembly. Each time you remove and reinstall the air filter in the future, you must first remove the fan-tray assembly.
Step 1 With the fan-tray assembly removed, place the ONS 15454 face down on a flat surface.
Step 2 Locate the three screw holes that run along the left and right sides of the bottom of the shelf assembly.
Step 3 Secure each bracket to the bottom of the shelf assembly using the screws provided.
Each bracket has a filter stopper and a flange on one end. Make sure to attach the brackets with the stoppers and flanges facing the rear of the shelf assembly (the top, if the ONS 15454 is face-down during installation).
Figure 1-20 illustrates bottom bracket installation. If you do not use the bottom brackets, in the future you must remove the fan-tray assembly before removing the air filter. The bottom brackets enable you to clean and replace the air filter without removing the fan-tray assembly.
Figure 1-20 Installing the bottom brackets
If you are using the bottom brackets to install the fan-tray air filter, you can install three shelf assemblies in a standard seven-foot rack. If you are not using the bottom brackets, you can install four shelf assemblies in a rack.
Step 4 Slide the air filter into the shelf assembly.
Procedure: Install the Fan-Tray Assembly
To install the fan-tray assembly, it is not necessary to move any of the cable-management facilities.
Caution You must place the edge of the air filter flush against the front of the fan-tray assembly compartment when installing the fan tray on top of the filter. Failure to do so could result in damage to the filter, the fan tray, or both.
Caution Do not force a fan-tray assembly into place. Doing so can damage the connectors on the fan tray and/or the connectors on the back panel of the shelf assembly.
Step 1 Open the front door of the shelf assembly. Removing the front door is optional.
Step 2 Slide the fan tray into the shelf assembly until the electrical plug at the rear of the tray plugs into the corresponding receptacle on the backplane.
Step 3 To verify that the tray has plugged into the backplane, check that the LCD on the front of the fan tray is activated.
Figure 1-21 shows the location of the fan tray.
Figure 1-21 Installing the fan-tray assembly
1.8 Power and Ground Installation
This section explains how to connect the ONS 15454 assembly to the power supply. Ground the equipment according to Telcordia standards or local practices.
Warning Shut off the power from the power source or turn off the breakers before beginning work.
Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use.
Caution Always use the supplied ESD wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
Warning Do not mix conductors of dissimilar metals in a terminal or splicing connector where physical contact occurs (such as copper and aluminum, or copper and copper-clad aluminum), unless the device is suited for the purpose and conditions of use.
Warning Connect the ONS 15454 only to a DC power source that complies with the safety extra-low voltage (SELV) requirements in IEC 60950-based safety standards.
Warning The ONS 15454 relies on the protective devices in the building installation to protect against short circuit, overcurrent, and grounding faults. Ensure that the protective devices are properly rated to protect the system, and that they comply with national and local codes.
Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring.
Cisco recommends the following wiring conventions, but customer conventions prevail:
•Red wire for battery connections (-48V DC)
•Black wire for battery return connections (0V DC)
The ONS 15454 has redundant -48V DC #8 power terminals on the shelf assembly backplane. The terminals are labeled BAT1, RET1, BAT2, and RET2 and are located on the lower section of the backplane behind a clear plastic cover. See the "Lower Backplane Cover" section for information about accessing the power terminals.
To install redundant power feeds, use four power cables and one ground cable. For a single power feed, only two power cables (#10 AWG, copper conductor, 194°F [90°C]) and one ground cable (#6 AWG) are required. Use a conductor with low impedance to ensure circuit overcurrent protection. However, the conductor must have the capability to safely conduct any fault current that might be imposed.
Note If you are installing power on a Release 3.0 ONS 15454 shelf assembly (15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1, P/N: 800-07149), the #12 to #14 AWG power cable and #14 AWG ground cable are required.
The existing ground post is a #10-32 bolt. The nut provided for a field connection is also a #10, with an integral lock washer. The lug must be a dual-hole type and rated to accept the #6 AWG cable. Two posts are provided on the Cisco ONS 15454 to accommodate the dual-hole lug. Figure 1-22 shows the location of the ground posts.
Figure 1-22 Ground posts on the ONS 15454 backplane
For information about attaching ferrites to power cabling, see the "Ferrite Installation" section.
Warning When installing redundant power feeds, do not use aluminum conductors.
Warning If you use redundant power leads to power the ONS 15454, disconnecting one lead will not remove power from the node.
Procedure: Install Redundant Power Feeds
Ground only one cable to ground the shelf assembly. Terminate the other end of the ground cable to ground according to local site practice. The ONS 15454 backplane also has a ground terminal on the right side of the backplane. Connect a ground terminal for the frame ground (FGND) terminal according to local site practice.
If the system loses power or both TCC+ cards are reset, you must reset the ONS 15454 clock. After powering down, the date defaults to January 1, 1970, 00:04:15. To reset the clock, see the "Setting Up Basic Node Information" section on page 3-2.
Note If you encounter problems with the power supply, refer to the Cisco ONS 15454 Troubleshooting and Maintenance Guide for possible causes.
Warning Do not apply power to the ONS 15454 until you complete all installation steps and check the continuity of the -48V DC and return.
Step 1 Measure and cut the cables as needed to reach the ONS 15454 from the fuse panel. Figure 1-23 shows the ONS 15454 power terminals.
Step 2 Dress the power and ground cables according to local site practice.
Warning When installing the ONS 15454, the ground connection must always be made first and disconnected last.
Figure 1-23 ONS 15454 power terminals
Step 3 Remove or loosen the #8 power terminal screws on the ONS 15454. To avoid confusion, label the cables connected to the BAT1/RET1 power terminals as 1 and the cables connected to the BAT2/RET2 power terminals as 2.
Note Use only pressure terminal connectors, such as ring and fork types, when terminating the battery, battery return, and frame ground conductors.
Caution Before you make any crimp connections, coat all bare conductors (battery, battery return, and frame ground) with an appropriate antioxidant compound. Bring all unplated connectors, braided strap, and bus bars to a bright finish, then coat with an antioxidant before you connect them. You do not need to prepare tinned, solder plated, or silver-plated connectors and other plated connection surfaces, but always keep them clean and free of contaminants.
Caution When terminating power, return, and frame ground, do not use soldering lug, screwless (push-in) connectors, quick-connect, or other friction-fit connectors.
Step 4 Strip 1/2 inch of insulation from all power cables that you will use. Crimp the lugs onto the ends of all power leads.
Note When terminating battery and battery return connections as shown in Figure 1-23, follow a torque specification of 10 in-lbs. When terminating a frame ground, use the kep-nut provided with the ONS 15454 and tighten it to a torque specification of 31 in-lbs. The kep-nut provides a frame ground connection that minimizes the possibility of loosening caused by rotation during installation and maintenance activity. This type of prevention is inherently provided by the terminal block for battery and battery return connections.
Step 5 Terminate the return 1 lead to the RET1 backplane terminal. Use oxidation-prevention grease to keep connections non-corrosive.
Warning Do not secure multiple connectors with the same bolt assembly.
Step 6 Terminate the negative 1 lead to the negative BAT1 backplane power terminal. Use oxidation prevention grease to keep connections non-corrosive.
Step 7 If you use redundant power leads, terminate the return 2 lead to the positive RET2 terminal on the ONS 15454. Terminate the negative 2 lead to the negative BAT2 terminal on the ONS 15454. Use oxidation-preventative grease to keep connections non-corrosive.
Step 8 Route the cables out below the power terminals using the plastic cable clamp.
1.9 Alarm, Timing, LAN, and Craft Pin Connections
Caution Always use the supplied ESD wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
The ONS 15454 has a backplane pin field located at the bottom of the backplane. The backplane pin field provides 0.045 square inch wire-wrap pins for enabling external alarms, timing input and output, and craft interface terminals. This section describes the backplane pin field and the pin assignments for the field. Figure 1-24 shows the wire-wrap pins on the backplane pin field. Beneath each wire-wrap pin is a frame ground pin. Frame ground pins are labeled FG1, FG2, FG3, etc. Install the ground shield of the cables connected to the backplane to the ground pin that corresponds to the pin field used. Figure 1-24 shows pinouts for the ONS 15454.
Figure 1-24 ONS 15454 backplane pinouts
Note The X.25, Modem, and TBOS pin fields are not active.
1.9.1 Alarm Installation
The alarm pin field supports up to 17 alarm contacts, including four audible alarms, four visual alarms, one alarm cutoff (ACO), and four user-definable alarm input and output contacts.
Audible alarm contacts are in the LOCAL ALARM AUD pin field and visual contacts are in the LOCAL ALARM VIS pin field. Both of these alarms are in the LOCAL ALARMS category. User-definable contacts are in the ENVIR ALARM IN and ENVIR ALARM OUT pin fields. These alarms are in the ENVIR ALARMS category; you must have the AIC card installed to use the ENVIR ALARMS. Alarm contacts are Normally Open (N/O), meaning that the system closes the alarm contacts when the corresponding alarm conditions are present. Each alarm contact consists of two wire-wrap pins on the shelf assembly backplane. Visual and audible alarm contacts are classified as Critical, Major, Minor, and Remote. Figure 1-24 shows alarm pin assignments.
Visual and audible alarms are typically wired to trigger an alarm light at a central alarm collection point when the corresponding contacts are closed. You can use the Alarm Cutoff pins to activate a remote ACO for audible alarms. You can also activate the ACO function by pressing the ACO button on the TCC+ card faceplate. The ACO function clears all audible alarm indications. After clearing the audible alarm indication, the alarm is still present and viewable in the Alarms tab in CTC.
Procedure: Install Alarm Wires on the Backplane
Step 1 Use #22 or #24 AWG alarm wires.
Step 2 Wrap the alarm wires on the appropriate wire-wrap pins according to local site practice.
Note For information about attaching ferrites to wire-wrap pin fields, see the "Ferrite Installation" section.
1.9.2 Timing Installation
The ONS 15454 backplane supports two Building Integrated Timing Supply (BITS) clock pin fields. The first four BITS pins, rows 3 and 4, support output and input from the first external timing device. The last four BITS pins, rows 1 and 2, perform the identical functions for the second external timing device. Table 1-2 lists the pin assignments for the BITS timing pin fields.
Note Refer to Telcordia SR-NWT-002224 for rules about provisioning timing references
Procedure: Install Timing Wires on the Backplane
Step 1 Use #22 or #24 AWG wire.
Step 2 Wrap the clock wires on the appropriate wire-wrap pins according to local site practice.
Step 3 The BITS pin field (FG1) has a frame ground pin beneath it. Wrap the ground shield of the alarm cable to the frame ground pin.
Note For more detailed information about timing, see the "Setting Up ONS 15454 Timing" section on page 3-12.
1.9.3 LAN Installation
Use the LAN pins on the ONS 15454 backplane to connect the ONS 15454 to a workstation or Ethernet LAN, or to a LAN modem for remote access to the node. You can also use the LAN port on the TCC+ faceplate to connect a workstation or to connect the ONS 15454 to the network. Table 1-3 shows the LAN pin assignments.
Before you can connect an ONS 15454 to other ONS 15454s or to a LAN, you must change the default IP address that is shipped with each ONS 15454 (192.1.0.2). See the "Change IP Address, Default Router, and Network Mask Using the LCD" procedure on page 3-4.
*The Cisco ONS 15454 is DCE.
Procedure: Install LAN Wires on the Backplane
Step 1 Use #22 or #24 AWG wire.
Step 2 Wrap the wires on the appropriate wire-wrap pins according to local site practice.
Caution Cross talk may result if both Rx and Tx pins connect on the same twisted pair of wires from the CAT 5 cable. The two Tx pins need to be on one twisted pair, and the two Rx pins need to be on another twisted pair.
Step 3 A frame ground pin is located beneath each pin field (FG2 for the LAN pin field). Wrap the ground shield of the LAN interface cable to the frame ground pin.
1.9.4 TL1 Craft Interface Installation
You can use the craft pins on the ONS 15454 backplane or the RS-232 port on the TCC+ faceplate to create a VT100 emulation window to serve as a TL1 craft interface to the ONS 15454. Use a straight-through cable to connect to the RS-232 port. Table 1-4 shows the pin assignments for the CRAFT pin field.
Note You cannot use the craft backplane pins and the RS-232 port on the TCC+ card simultaneously.

Step 3 Wrap the ground shield of the craft interface cable to the frame-ground pin.
Step 4 Wrap the ground wire of your computer cable to pin A3 on the craft pin field.
1.10 Coaxial Cable Installation
Caution Always use the supplied ESD wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
When using ONS 15454 DS-3 electrical cables, the cables must terminate on an EIA installed on the ONS 15454 backplane. EIAs are available with SMB and BNC connectors. All DS-3 cables connected to the ONS 15454 DS-3 card must terminate with coaxial cables using the desired connector type to connect to the specified EIA. For information about physically installing an EIA in the field, see the "Install a BNC, High-Density BNC, or SMB EIA" procedure. For information about coaxial cable management, see the "Coaxial Cable Management" section.
The electromagnetic compatibility (EMC) performance of the system depends on good-quality DS-3 coaxial cables, such as Shuner Type G 03233 D, or the equivalent.
1.10.1 BNC Connector Installation
For a description of BNC EIAs, see the "BNC EIA" section. The BNC connectors on the EIA supports Trompeter UCBJ224 (75 Ohm) 4 leg connectors. Right-angle mating connectors for the connecting cable are AMP 413588-2 (75 Ohm) connectors. If preferred, you can also use a straight connector of the same type. Use RG-59/U cable to connect to the ONS 15454 BNC EIA. These cables are recommended to connect to a patch panel and are designed for long runs of up to 450 feet.
Procedure: Install Coaxial Cable With BNC Connectors
Step 1 Place the BNC cable connector over the desired connection point on the backplane.
Figure 1-25 shows how to connect a coaxial cable to the BNC EIA using a right-angle BNC cable connector.
Step 2 Position the cable connector so that the slot in the connector is over the corresponding notch at the backplane connection point.
Step 3 Gently push the connector down until the notch backplane connector slides into the slot on the cable connector.
Step 4 Turn the cable connector until the notch clicks into place.
Step 5 Tie wrap or lace the cables to the EIA according to Telcordia standards (GR-1275-CORE) or local site practice.
Step 6 Route the cables to the nearest side of the shelf assembly through the side cutouts according to local site practice. The rubber coated edges of the side cutouts prevent the cables from chafing.
Figure 1-25 Using a right-angle connector to install coaxial cable with BNC connectors
Note Slots 1, 3, 15 and 17 are designated protection slots when BNC connectors are used. Slots 5, 6, 11, and 12 do not support DS3-12 cards when BNC connectors are used. A total of four DS3-12 cards can be used to carry traffic with BNC connectors.
Step 7 Label all cables at each end of the connection to avoid confusion with cables that are similar in appearance.
1.10.2 High-Density BNC Connector Installation
The High-Density BNC EIA supports Trompeter UCBJ224 (75 Ohm) 4 leg connectors. Use straight connectors on RG-59/U cable to connect to the High-Density BNC EIA. Cisco recommends these cables for connection to a patch panel; they are designed for long runs of up to 450 feet. For more detail, see the "High-Density BNC EIA" section.
Although not required, Cisco strongly recommends using the BNC insertion tool to connect cables to the EIA. Refer to the Cisco ONS 15454 Troubleshooting and Maintenance Guide for more information about the insertion tool.
Procedure: Install Coaxial Cable With High-Density BNC Connectors
Step 1 Place the BNC cable connector over the desired connection point on the backplane.
Step 2 Using the insertions tool, position the cable connector so that the slot in the connector is over the corresponding notch at the backplane connection point.
Step 3 Gently push the connector down until the notch backplane connector slides into the slot on the cable connector.
Step 4 Turn the cable connector until the notch clicks into place.
Step 5 Tie wrap or lace the cables to the EIA according to Telcordia standards (GR-1275-CORE) or local site practice.
Step 6 Route the cables to the nearest side of the shelf assembly through the side cutouts according to local site practice.
The rubber coated edges of the side cutouts prevent the cables from chafing.
1.10.3 SMB Connector Installation
The SMB backplane cover is similar to the BNC cover. For further detail, see the "SMB EIA" section. The SMB connectors on the EIA are AMP 415504-3 (75 Ohm) 4 leg connectors. Right-angle mating connectors for the connecting cable are AMP 415484-2 (75 Ohm) connectors. Use RG-179/U cable to connect to the ONS 15454 EIA. Cisco recommends these cables for connection to a patch panel; they are not designed for long runs (over 50 feet). Range does not affect loopback testing.
For information about attaching ferrites to SMB/BNC connectors, see the "Ferrite Installation" section.
Procedure: Install Coaxial Cable with SMB Connectors
Refer to Figure 1-26 when performing the following steps.
Step 1 Place the SMB cable connector over the desired connection point on the backplane.
Step 2 Gently push the connector until it clicks into place.
Step 3 Tie wrap or lace the cables to the EIA according to Telcordia standards (GR-1275-CORE) or local site practice.
Step 4 Route the cables to the nearest side of the shelf assembly into rack runs according to local site practice.
Figure 1-26 Installing coaxial cable with SMB connectors
Warning Metallic interfaces for connection to outside plant lines (such as T1/E1/T3/E3, etc.) must be connected through a registered or approved device such as CSU/DSU or NT1.
Step 5 Label the transmit, receive, working, and protect cables at each end of the connection to avoid confusion with cables that are similar in appearance.
1.11 DS-1 Cable Installation
DS-1s support both twisted pair wire-wrap cabling and AMP Champ connector cabling. Install the proper backplane EIA on the ONS 15454 for each cabling option. This section provides information about the DS-1 EIA options.
For information about DS-1 cable management, see the "DS-1 Twisted-Pair Cable Management" section.
1.11.1 Twisted Pair Wire-Wrap Installation
Installing twisted-pair, wire-wrap DS-1 cables requires separate pairs of grounded twisted-pair cables for receive (in) and transmit (out). Prepare four cables, two for receive and two for transmit, for each DS-1 facility to be installed.
Caution Always use the supplied ESD wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
If you use DS-1 electrical twisted-pair cables, equip the ONS 15454 with an SMB EIA on each side of the backplane where DS-1 cables will terminate. You must install special DS-1 electrical interface adapters, commonly referred to as a balun, on every transmit and receive connector for each DS-1 termination.
Note DS-1 electrical interface adapters project an additional 1.72 inches from the ONS 15454 backplane.
If you install DS-1 cards in the ONS 15454, you must fit the corresponding transmit and receive SMB connectors on the EIA with a DS-1 electrical interface adapter. You can install the adapter on the SMB connector for the port. The adaptor has wire-wrap posts for DS-1 transmit and receive cables. Figure 1-27 shows the DS-1 electrical interface adapter.
Figure 1-27 A DS-1 electrical interface adapter (balun)
Each DS-1 electrical interface adapter has a female SMB connector on one end and a pair of .045 inch square wire-wrap posts on the other end. The wire-wrap posts are .200 inches apart.
Procedure: Install DS-1 Cables Using Electrical Interface Adapters (Balun)
All DS-1 cables connected to the ONS 15454 DS-1 ports must terminate with twisted-pair cables to connect to the DS-1 electrical interface adapter. The DS-1 electrical interface adapters project 1.72 inches beyond the SMB EIA.
Step 1 Attach the SMB connector on the adapter to the SMB connector for the port's transmit pair on the backplane.
Step 2 Attach the SMB connector on an adapter to the SMB connector for the port's receive pair on the backplane.
Step 3 Terminate the DS-1 transmit and receive cables for the port to the wire-wrap posts on the adapter:
a. Using a wire-wrap tool, connect the receive cables to the receive adapter pins on the backplane connector for the desired port.
b. Connect the transmit cables to the transmit adapter pins on the backplane connector for the desired port.
c. Terminate the shield ground wire on the DS-1 cable to ground according to local site practice.
If you put DS1N-14 cards in Slots 3 and 15 to form 1:N protection groups, do not wire Slots 3 and 15 for DS-1 electrical interface adapters.
Figure 1-28 shows a ONS 15454 backplane with an SMB EIA with DS-1 electrical interface adapters attached on both sides of the shelf assembly to create DS-1 twisted-pair termination points.

1.11.2 AMP Champ Connector Installation
To install AMP Champ connector DS-1 cables, you must use 64-pin bundled cable connectors with a 64-pin male AMP Champ connector. You need an AMP Champ connector #552276-1 for the receptacle side and #1-552496-1 (for cable diameter .475in.-.540in) or #2-552496-1 (for cable diameter .540in.-.605in.) for the right-angle shell housing (or their functional equivalent). The corresponding 64-pin female AMP Champ connector on the AMP Champ EIA supports one receive and one transmit for each DS-1 port for the corresponding card slot.
Because each DS1-14 card supports 14 DS-1 ports, only 56 pins (28 pairs) of the 64-pin connector are used. Prepare one 56-wire cable for each DS-1 facility installed. Table 1-5 shows the pin assignments for the AMP Champ connectors on the ONS 15454 AMP Champ EIA. See the "AMP Champ EIA" section for more information about the AMP Champ EIA.
Table 1-6 shows the pin assignments for the AMP Champ connectors on the ONS 15454 AMP Champ EIA for a shielded DS1 cable.
Caution Always use the supplied ESD wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
When using DS-1 AMP Champ cables, you must equip the ONS 15454 with an AMP Champ connector EIA on each side of the backplane where DS-1 cables will terminate. Each AMP Champ connector on the EIA corresponds to a slot in the shelf assembly and is numbered accordingly. The AMP Champ connectors have screw-down tooling at each end of the connector. To install an AMP Champ backplane cover, see the "AMP Champ EIA" section.
Procedure: Install DS-1 AMP Champ Cables on the AMP Champ EIA
Step 1 Prepare a 56-wire cable for each DS-1 card you will install in the shelf assembly. See Table 1-5 for the ONS 15454 AMP Champ connector pin assignments.
Step 2 Connect the male AMP Champ connector on the cable to the female AMP Champ connector on the ONS 15454 backplane.
Step 3 Use the clips on the male AMP Champ connector to secure the connection.
The female connector has grooves on the outside edge for snapping the clips into place.
Note To install optical cable, you must first install optical cards.
1.12 Card Installation
This section describes the how to install ONS 15454 cards. The procedure for installing ONS 15454 cards is nearly identical for each card. AIC card installation is slightly different from all other cards and is described in its own procedure. The XC/XCVT /XC10G and TCC+ installation procedures are virtually identical and are described in one procedure. Installation for all other cards is the same and is covered by one procedure.
The order in which you install cards is important. The proper sequence follows:
1. TCC+ cards
2. XC/XCVT/XC10G cards
3. Optical cards
4. Electrical cards
5. Ethernet cards
6. AIC card
Note Because all other cards boot from the active TCC+ card which houses the ONS 15454 software, you must install the TCC+ card before booting any other cards. See Chapter 2, "Software Installation" for information about the TCC+ card and software versions.
Note Before installing cards, verify that the power is turned on.
ONS 15454 cards have electrical plugs at the back that plug into electrical connectors on the shelf assembly backplane. When the ejectors are fully closed, the card plugs into the assembly backplane. Figure 1-29 shows card installation.
Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.
Caution Always use the supplied ESD wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
Warning Class I (21 CFR 1040.10 and 1040.11) and Class 1M (IEC 60825-1 2001-01) laser products.
Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam or view directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.
Warning The laser is active when the card is booted and the safety key is in the on position (labeled 1). The port does not have to be in service for the laser to be on. The laser is off when the safety key is off (labeled 0).
Figure 1-29 Installing cards in the ONS 15454
1.12.1 Slot Requirements
The ONS 15454 shelf assembly has 17 card slots numbered sequentially from left to right. Slots 1-4 and 14-17 are multispeed slots. They can host any ONS 15454 card, except the OC48IR 1310, OC48LR 1550, OC48ELR 1550, and OC192LR 1550 cards. Slots 5, 6, 12 and 13 are high-speed slots. They can host any ONS 15454 card, including the OC48IR 1310, OC48LR 1550, OC48ELR 1550, and OC192LR 1550 cards. You can install the OC48 IR/STM16 SH AS 1310 and the OC48 LR/STM16 LH AS 1550 cards in any multispeed or high-speed card slot.
Slots 7 and 11 are dedicated to TCC+ cards. Slots 8 and 10 are dedicated to cross-connect (XC, XCVT, XC10G) cards. Slot 9 is reserved for the optional Alarm Interface Controller (AIC) card. Slots 3 and 15 can also host DS1N-14 and DS3N-12 cards that are used in 1:N protection.
Caution Do not operate the ONS 15454 with a single TCC+ card or a single XC/XCVT/XC10G card installed. Always operate the shelf assembly with one working and one protect card of the same type.
Shelf assembly slots have symbols indicating the type of cards that you can install in them. Each ONS 15454 card has a corresponding symbol. The symbol on the card must match the symbol on the slot.
Table 1-7 shows the slot and card symbol definitions.
Table 1-8 lists the number of ports, line rates, connector options, and connector locations for ONS 15454 optical and electrical cards.
* When used as a protect card, the card does not have a physical external connection. The protect card connects to the working card(s) through the backplane and becomes active when the working card fails. The protect card then uses the physical connection of the failed card.
Procedure: Install the TCC+ and XC/XCVT/XC10G Cards
Although the installation procedure is the same for both TCC+ and XC/XCVT/XC10G cards, you must install the TCC+ card and let it initialize before installing the XC/XCVT/XC10G cards. The TCC+ card houses the ONS 15454 software. For a detailed explanation, see Chapter 2, "Software Installation."
Note This is not the procedure to use when upgrading from XC to XCVT cards or from XCVT to XC10G cards. If you are performing an XC to XCVT upgrade, an XCVT to a XC10G upgrade, or a TCC to TCC+ upgrade, refer to the Cisco ONS 15454 Troubleshooting and Maintenance Guide.
Step 1 Open the card ejectors.
Step 2 Slide the card along the guide rails into the correct slot (Slot 8 or 10 for the XC/XCVT/XC10G and Slot 7 or 11 for the TCC+).
Step 3 Close the ejectors.
Step 4 Verify that power is applied to the shelf assembly.
Step 5 Verify the LED activity as described in Table 1-9.
Note If the FAIL LED is lit continuously on the TCC+ card, see the tip below about the TCC+ automatic upload.
Step 6 Verify that the ACT/STBY LED is the correct color for the card (green for active, amber for standby). The IP address for the node, the temperature of the ONS 15454, and the time of day will be displayed on the LCD. The default time and date is 12:00 AM, January 1, 1970.
Tip When a TCC+ card installed in the shelf assembly has a different version of the ONS 15454 software installed than the version running on the active TCC+, the newly-installed TCC+ card automatically loads the software version running on the active TCC+. You do not need to do anything in this situation. However, the loading TCC+ card will not boot up in the normal manner. When the card is first inserted, the red FAIL LED stays on for a short period. The FAIL LED then blinks normally and all LEDs go dark. The FAIL LED and the ACT/STBY LED flash alternately every 30 to 45 seconds as the new software loads onto the new TCC+ card. After loading the new software for approximately 30 minutes, the TCC+ card becomes the standby card and the amber LED is illuminated.
Procedure: Install Optical, Electrical, and Ethernet Cards
Although the installation procedure is the same for optical, electrical, and Ethernet cards, you must install the optical cards before installing the electrical cards.
Warning Before installing an OC-192 card, make sure the safety key on the faceplate is in off position (labeled 0). When in the on position (labeled 1), the laser is activated.
Step 1 Open the card ejectors.
Step 2 Slide the card along the guide rails into the correct slot.
Step 3 Close the ejectors.
Step 4 Verify that power is applied to the shelf assembly.
Step 5 Verify the LED activity, as described in Table 1-10.
Step 6 Verify that the ACT or ACT/STBY LED is on. The signal fail (SF) LED can persist until all card ports connect to their far end counterparts and a signal is present.
Step 7 When you have displayed CTC on your workstation, verify that the card appears in the correct slot on the CTC node view. See Chapter 2, "Software Installation" for CTC information and setup instructions.
Procedure: Install the AIC Card
Step 1 Open the card ejectors.
Step 2 Slide the card along the guide rails into the correct slot.
Step 3 Close the ejectors.
Step 4 Verify that power is applied to the shelf assembly.
Step 5 Verify the that red FAIL LED remains lit for 1 second.
Step 6 Verify that the red FAIL LED blinks for 1 to 5 seconds.
Step 7 Verify that after 1 to 5 seconds, all LEDs blink once and turn off.
Step 8 Verify that the ACT LED is on.
1.12.2 Gigabit Interface Converter
GBICs are hot-swappable input/output devices that plug into a Gigabit Ethernet card to link the port with the fiber-optic network. The type of GBIC determines the maximum distance that the Ethernet traffic will travel from the card to the next network device.
Cisco provides two GBIC models: one for short reach applications (part number 15454-GBIC-SX) and one for long-reach applications (15454-GBIC-LX). The short reach, or "SX" model, connects to multimode fiber of up to 550 m in length, and the long reach, or "LX" model, requires single-mode fiber of up to 10 km in length. Because the GBICs are very similar in appearance, check the label on the GBIC carefully before installing it. The E1000-2, E1000-2G, and G1000-4 cards support SX and LX GBICs.
Note The SX and LX GBIC models are incompatible and cannot be used together.
For a description of GBICs and their capabilities, see Chapter 9, "Ethernet Operation."
Procedure: Install Gigabit Interface Converters
Step 1 Remove the GBIC from its protective packaging.
Step 2 Check the part number to verify that the GBIC is the correct type for your network.
Step 3 Grip the sides of the GBIC with your thumb and forefinger and insert it into the slot on the front panel of the Gigabit Ethernet card (shown in Figure 1-30).
GBICs are hot-swappable and can therefore be installed/removed while the card/shelf assembly is powered and running.
Note GBICs are keyed to prevent incorrect installation.
Figure 1-30 Installing a GBIC on an E1000-2 card
Step 4 Slide the GBIC through the cover flap until you hear a click.
The click indicates the GBIC is locked into the slot.
Warning GBICs are Class I laser products. These products have been tested and comply with Class I limits.
Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode fiber optic modules when no cable is connected. Avoid exposure and do not stare into open apertures.
Step 5 When you are ready to attach the network interface fiber-optic cable, remove the plug from the GBIC and save the plug for future use.
Step 6 Install and route the cable. See the "Optical Cable Management" section for routing instructions.
Procedure: Remove a Gigabit Interface Converter
Step 1 Disconnect the network fiber cable from the GBIC SC connector.
Step 2 Release the GBIC from the slot by simultaneously squeezing the two plastic tabs (one on each side of the GBIC).
Step 3 Slide the GBIC out of the Gigabit Ethernet module slot.
A flap closes over the GBIC slot to protect the connector on the Gigabit Ethernet card.
1.13 Fiber-Optic Cable Installation
This section explains how to install optical fibers on OC-N cards.
Caution Always use the supplied ESD wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
ONS OC-N cards feature SC connectors. To install fiber-optic cables in the ONS 15454, a fiber cable with the corresponding connector type must be connected to the transmit and receive ports on the ONS 15454 cards. On ONS 15454 optical card ports, the top connector is transmit and the bottom connector is receive. Cisco recommends that the transmit and receive and the working and protection fibers be labeled at each end of the fiber span to avoid confusion with cables that are similar in appearance.
For information about fiber cable management, see the "Optical Cable Management" section.
Warning Class I (21 CFR 1040.10 and 1040.11) and Class 1M (IEC 60825-1 2001-01) laser products.
Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam or view directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.
Warning The laser is active when the card is booted and the safety key is in the on position (labeled 1). The port does not have to be in service for the laser to be on. The laser is off when the safety key is off (labeled 0).
Warning Follow all directions and warning labels when working with optical fibers. To prevent eye damage, never look directly into a fiber or connector.
Caution Do not user fiber loopbacks with the OC192 LR 1550 card unless you are using a 20 dB attentuator. Never connect a direct fiber loopback. Using fiber loopbacks causes irreparable damage to the OC-192 card.
Procedure: Install Fiber-Optic Cables on OC-N Cards
Note Clean all fiber connectors thoroughly. Dust particles can degrade performance. Put caps on any fiber connectors that are not used.
Step 1 Place the SC connector in front of the connection point on the card faceplate. Each card supports at least one transmit and one receive connector to create an optical carrier port. Figure 1-31 shows the cable location.
Figure 1-31 Installing fiber-optic cables
Step 2 Align the keyed ridge of the cable connector with the receiving slot on the faceplate connection point.
Step 3 Gently push the cable connector into the faceplate connection point until the connector snaps into place.
Procedure: Install the Fiber Boot
Cisco provides clear plastic fiber boots for the OC-3, OC-12, and OC-48 (except OC48 AS) cards. The boots prevent hanging fibers from bending too sharply, which may degrade performance. The boots also prevent the front door from interfering with hanging fibers. The fiber boots are not necessary for the OC-192 and the OC-48 AS cards because of the angled SC connector. Figure 1-32 shows the fiber boot attachment.
You can install the fiber boots on the fiber-optic cables before or after the fibers are attached to the optic card.
Step 1 Position the open slot of the fiber boot underneath the fiber cable.
Step 2 Push the fiber cable down into the fiber boot.
Step 3 Twist the fiber boot to lock the fiber cable into the tail end of the fiber boot.
Step 4 Slide the fiber boot forward along the fiber cable until the fiber boot fits snugly onto the end of the SC cable connector.
Figure 1-32 Attaching a fiber boot
1.14 Cable Routing and Management
The ONS 15454 cable management facilities include the following:
•Cable management clips on optical card faceplates
•A cable-routing channel that runs the width of the shelf assembly
•Plastic horseshoe-shaped fiber guides at each side opening of the cable-routing channel that ensure the proper bend radius is maintained in the fibers
Note You can remove the fiber guide if necessary to create a larger opening (if you need to route Cat-5 Ethernet cables out the side, for example). To remove the fiber guide, take out the three screws that anchor it to the side of the shelf assembly.
•A fold-down door that provides access to the cable-management tray
•Cable tie-wrap facilities on EIAs that secure cables to the cover panel
•Reversible jumper routing fins that enable you to route cables out either side by positioning the fins as desired
•Jumper slack storage reels (2) on each side panel that reduce the amount of slack in cables that are connected to other devices
Note To remove the reels, take out the screw in the center of each reel.
Figure 1-33 shows the cable management facilities that you can access through the fold-down front door, including the cable-routing channel and the jumper routing fins.
Figure 1-33 Managing cables on the front panel
1.14.1 Optical Cable Management
Optical cables connect to the SC connectors which are located on the faceplate of the optical cards and on GBICs. Route optical cables down through the fiber management clips on the optical card faceplate (shown in Figure 1-34) or, if the optical cables are connected to GBICs, route them down through the jumper routing fins (Ethernet cards do not have fiber management clips).
Route optical cables into the cable management area of the shelf assembly, through a cutout in the nearest side of the assembly, and onto the side of the assembly. A hinged panel on the front of the shelf assembly folds down to provide access to the cable-management tray.
Figure 1-34 Routing fiber-optic cables on the optical-card faceplate
Procedure: Route Fiber-Optic Cables in the Shelf Assembly
Step 1 Open the fold-down front door on the cable-management tray.
Step 2 Route the cable on the card faceplate through the fiber clip on the faceplate.
GBICs do not have fiber clips; therefore, if you are routing optical cable from an E1000-2-G or E1000-2 card, skip to Step 3.
Step 3 Route the cables into the cable-management tray.
Step 4 Route the cables out either side of the cable-management tray through the cutouts on each side of the shelf assembly. Use the reversible fiber guides to route cables out the desired side.
Step 5 Close the fold-down front door when all cables in the front compartment are properly routed.
Figure 1-35 shows the fold-down front door of the shelf assembly open to display the cable routing channel.
Figure 1-35 The fold-down front door of the cable-management tray (displaying the cable routing channel)
1.14.2 Coaxial Cable Management
Coaxial cables connect to EIAs on the ONS 15454 backplane using cable connectors. EIAs feature cable-management eyelets for tie wrapping or lacing cables to the cover panel.
Procedure: Route the Coaxial Cables
Step 1 Tie wrap or lace the coaxial cables according to local site practice and route the cables through the side cutouts on either side of the ONS 15454. The rubber coated edges of the side cutouts prevent the cables from chafing.
Note When using the RG179 cable with SMB connectors, remember that the maximum distance available with the RG179 cable is less than the maximum distance available with standard RG59 cable. If you only use the RG179, the maximum available distance is 50 feet versus the 450 feet available with the larger RG59 cable.
Step 2 Use short lengths of "pigtail" RG179 to terminate the shelf assembly.
Step 3 Use standard RG59 connected to the RG179 for the remainder of the cable run. When using a 10-foot section of the RG179, you can attach a maximum length of 437 feet of RG59. When using a 30-foot section of RG179, you can attach a maximum length of 311 feet of RG59.
The shorter maximum distance available with the RG179 is due to a higher attenuation rate for the thinner cable. The attenuation rate for RG59 cable (based on testing with Belden 923, the equivalent of 328A cable) is ~1.0 dB/100 feet at 22 Mhz (DS-3 data rate). The attenuation rate of RG179 is
6.3 db/100 feet. Use a figure of 5.0 for total cable loss when making calculations. Figure 1-36 shows one side of the ONS 15454 backplane with SMB EIAs and the coaxial cables properly routed.Figure 1-36 Routing coaxial cable through the SMB EIA backplane
1.14.3 DS-1 Twisted-Pair Cable Management
Connect twisted pair/DS-1cables to SMB EIAs on the ONS 15454 backplane using cable connectors and DS-1 electrical interface adapters (balun).
Procedure: Route DS-1 Twisted-Pair Cables
When using DS-1 twisted-pair cables, the backplane cover has cutouts over the SMB cable connectors. SMB EIAs feature cable-management eyelets for tie wrapping or lacing cables to the cover panel.
Step 1 Install DS-1 electrical interface adapters on every transmit and receive connector for DS-1 ports.
Step 2 Use wire-wrap posts on the DS-1 electrical interface adapters to connect the terminated incoming cables.
Step 3 Tie-wrap or lace the twisted-pair cables according to local site practice and route the cables into the side cutouts on either side of the ONS 15454.
1.14.4 AMP Champ Cable Management
EIAs have cable management eyelets to tiewrap or lace cables to the cover panel. Tie wrap or lace the AMP Champ cables according to local site practice and route the cables. If you configure the ONS 15454 for a 23-inch rack, two additional inches of cable management area is available on each side of the shelf assembly. See the "AMP Champ EIA" section and the "AMP Champ Connector Installation" section and the for more information.
1.14.5 BIC Rear Cover Installation
The ONS 15454 has an optional backplane interface connector (BIC) rear cover. This clear plastic cover provides additional protection for the cables and connectors on the backplane ( Figure 1-37). You can also install the optional spacers if more space is needed between the cables and rear cover ( Figure 1-38).
Figure 1-37 Clear BIC rear cover
Procedure: Install the BIC Rear Cover
Step 1 Locate the three screws that run vertically along the edges of the backplane.
Only one pair of screws lines up with the screw slots on the mounting brackets, making them easy to locate.
Step 2 Loosen the top and bottom screws on one edge of the backplane to provide room to slide the mounting brackets into place using the u-shaped screw slots on each end.
Step 3 Slide one of the mounting brackets into place and tighten the screws.
Step 4 Repeat Steps 2 and 3 for the second mounting bracket.
Step 5 Attach the cover by hanging it from the mounting screws on the back of the mounting brackets and pulling it down until it fits snugly into place.
Figure 1-38 Backplane attachment for BIC cover
Figure 1-39 Installing the BIC rear cover with spacers
1.15 Ferrite Installation
Place third-party ferrites on certain cables to dampen electromagnetic interference (EMI) from the ONS 15454. Ferrites must be added to meet the requirements of GR 1089. Refer to the ferrite manufacturer documentation for proper use and installation of the ferrites. The following illustrations show possible ferrite placements on the ONS 15454 for power cables, AMP Champ connectors, baluns, BNC/SMB connectors, and the wire-wrap pin field.
Procedure: Attach Ferrites to Power Cabling
Use a single oval ferrite TDK ZCAT2035-0930 for both pairs of cables and a block ferrite Fair Rite 0443164151 for each pair of cables.
Step 1 Wrap the cables once around and through the block ferrites and pull the cable straight through the oval ferrites.
Step 2 Place the oval ferrite between the ONS 15454 and the block ferrite as shown in Figure 1-40.
Step 3 Place the oval ferrite as close to the power terminals as possible and place the block ferrite within 5 to 6 inches of the power terminals.
Figure 1-40 Attaching ferrites to power cabling
Figure 1-41 shows the suggested method for attaching the ferrites to AMP Champ connectors. Use a block ferrite Fair Rite 0443164151 for each cable.
Figure 1-41 Attaching ferrites to AMP Champ connectors
Figure 1-42 shows the suggested method for attaching ferrites to baluns. Use an oval ferrite TDK ZCAT 1730-0730 for each cable.
