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
Warning
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 "Electrical Interface Assemblies" 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.
Note
Install the ONS 15454 in compliance with your local and national electrical codes:

1.2 Rack Installation
Warning
The ONS 15454 is 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.

1.2.1 Reversible Mounting Bracket
Caution
Caution
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.
1.2.2 Mounting a Single Node
Mounting the ONS 15454 in a rack requires a minimum of 18.5 inches of vertical rack space and one additional 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 1-2 shows the rack mounting position for the ONS 15454.
Figure 1-2 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 shelf assembly should be empty for easier lifting. The front door can also be removed to lighten the shelf assembly.
Note
1.2.3 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 external (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 external (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.
1.2.3.1 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 1-3.
Figure 1-3 A Four-shelf ONS 15454 Bay Assembly
1.3 Front Door
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.
The ONS 15454 features a locked door to the front compartment. A pinned hex 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 ( Figure 1-4) provides access to the shelf assembly, cable-management tray, fan-tray assembly, and LCD screen.
Figure 1-4 The ONS 15454 front door
You can remove the front door of the ONS 15454 to provide unrestricted access to the front of the shelf assembly ( Figure 1-5). 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.

1.4 Backplane Covers
If a backplane does not have an EIA panel installed, it should have two sheet metal backplane covers (one on each side of the backplane) ( Figure 1-8). (See the "Electrical Interface Assemblies" section for information on EIAs.) Each cover is held in place with nine 6-32 x 3/8 inch Phillips screws.
Figure 1-8 Backplane covers
1.4.1 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 fields, frame ground, and power terminals ( Figure 1-9).
Figure 1-9 Removing the lower backplane cover
1.4.2 Rear Cover
The ONS 15454 has an optional clear plastic rear cover. This clear plastic cover provides additional protection for the cables and connectors on the backplane ( Figure 1-10). The rear cover screw locations are shown in Figure 1-11. You can also install the optional spacers if more space is needed between the cables and rear cover ( Figure 1-12).
Figure 1-10 Clear rear cover
Figure 1-11 Backplane attachment for cover
Figure 1-12 Installing the plastic rear cover with spacers
1.4.3 Alarm Interface Panel
The AIP is located above the alarm pin fields 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).
Note
Note
Note
1.4.4 Alarm Interface Panel Replacement
If the alarm interface panel (AIP) fails, a MAC Fail alarm displays on the CTC Alarms menu and/or the LCD display on the fan tray will go blank. To perform an in-service replacement of the AIP, you must contact Cisco Technical Assistance Center (TAC) at 877-323-7368.
You can replace the AIP on an in-service system without affecting traffic (except Ethernet traffic). The circuit repair feature allows you to repair circuits affected by MAC address changes on a single node at a time. Circuit repair will work when all nodes are running the same software version. Each individual AIP upgrade requires an individual circuit repair; if AIPs are replaced on two nodes, the circuit repair must be performed twice.

1.5 Electrical Interface Assemblies
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. This section describes each EIA.
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. If the shelf was not shipped with the correct EIA interface, you must order and install the correct EIA.
EIAs are attached to the shelf assembly backplane to provide electrical interface 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).
EIAs have two sides. As you face the rear of the ONS 15454 shelf assembly, the right-hand side is the A side and the left-hand side is the B side. You can install EIAs on one or both sides of the ONS 15454 backplane in any combination. For example, you can use an AMP Champ EIA on side A and a BNC EIA on side B. The top of the EIA connector columns are labelled with the corresponding slot number, and EIA connector pairs are marked Tx and Rx to correspond to transmit and receive cables. EIAs come pre-installed on the ONS 15454 when ordered with the node.
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.
When using the RG-179 coaxial cable on an EIA, the maximum distance available (122 feet) is less than the maximum distance available with standard RG-59 (735A) cable (306 feet). The maximum distance when using the RG-59 (734A) cable is 450 feet. The shorter maximum distance available with the RG179 is due to a higher attenuation rate for the thinner cable. Attenuation rates are calculated using a DS-3 signal:
•
•
Table 1-1 gives the product numbers and common names for EIAs.
1.5.1 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). 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. You can use BNC EIAs for DS-3 (including the DS3XM-6) or EC-1 cards.
Figure 1-13 shows the ONS 15454 with pre-installed BNC EIAs.
To install coaxial cable with BNC connectors, refer to the Cisco ONS 15454 Procedure Guide.
Figure 1-13 A BNC backplane for use in 1:1 protection schemes
1.5.1.1 BNC Connectors
The EIA side marked "A" has 24 pairs of BNC connectors. The first 12 pairs of BNC connectors correspond to Ports 1-12 for a 12-port card and map to Slot 2 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 1 as a protect card for the card in Slot 2. 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.
1.5.1.2 BNC Insertion and Removal Tool
Due to the large number of BNC connectors on the High-Density BNC EIA, you might require a special tool for inserting and removing BNC EIAs ( Figure 1-14). This tool also helps with ONS 15454 patch panel connections.

1.5.2 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). 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. You can use High-Density BNC EIAs for DS-3 (including the DS3XM-6) or EC-1 cards. Figure 1-15 shows the ONS 15454 with pre-installed High-Density BNC EIAs.
To install coaxial cable with High-Density BNC connectors, refer to the Cisco ONS 15454 Procedure Guide.
Figure 1-15 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.
1.5.3 SMB EIA
The ONS 15454 SMB EIA supports AMP 415484-1 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. Range does not affect loopback testing.
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 (see the "Electrical Interface Adapters" section). SMB EIAs support 14 ports per slot when used with a DS-1 card, 12 ports per slot when used with a DS-3 or EC-1 card, and 6 ports per slot when used with a DS3XM-6 card.
Figure 1-16 shows the ONS 15454 with pre-installed SMB EIAs and the sheet metal cover and screw locations for the EIA. The SMB backplane cover is similar to the BNC cover. The SMB connectors on the EIA are AMP 415504-3 (75 Ohm) 4 leg connectors.
To install SMB connectors, refer to the Cisco ONS 15454 Procedure Guide.
Figure 1-16 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).
The EIA side marked "A" hosts 84 SMB connectors in six columns of 14 connectors. The "A" side columns are numbered 1-6 and correspond to Slots 1-6 on the shelf assembly. The EIA side marked "B" hosts an additional 84 SMB connectors in six columns of 14 connectors. The "B" side columns are numbered 12-17 and correspond to Slots 12-17 on the shelf assembly. The connector rows are numbered 1-14 and correspond to the 14 ports on a DS-1 card.
For DS-3 or EC-1, the EIA supports 72 transmit and 72 receive connectors, for a total of 144 SMB connectors (72 circuits). If you use a DS-3 or EC-1 card, only Ports 1-12 are active. If you use a DS3XM-6 card, only Ports 1 - 6 are active. The SMB connector pairs are marked "Tx" and "Rx" to identify transmit and receive cables for each port. If you use SMB connectors, you can install DS-1, DS-3, or EC-1 cards in any multispeed slot.
1.5.4 AMP Champ EIA
The ONS 15454 AMP Champ EIA supports 64-pin (32 pair) AMP Champ connectors for each slot on both sides of the shelf assembly where the EIA is installed. Cisco AMP Champ connectors are female AMP # 552246-1 with AMP # 552562-2 bail locks. Each AMP Champ connector supports 14 DS-1 ports. You can use AMP Champ EIAs with DS-1 cards only. Figure 1-17 shows the ONS 15454 with pre-installed AMP Champ EIAs and the corresponding sheet metal cover and screw locations for the EIA.
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 1-2 shows the pin assignments for the AMP Champ connectors on the ONS 15454 AMP Champ EIA.
Figure 1-17 An AMP EIA Champ backplane
The EIA side marked "A" hosts six AMP Champ connectors. The connectors are numbered 1-6 for the corresponding slots on the shelf assembly. Each AMP Champ connector on the backplane supports 14 DS-1 ports for a DS1-14 card, and each connector features 28 live pairs—one transmit pair and one receive pair—for each DS-1 port.
The EIA side marked "B" hosts six AMP Champ connectors. The connectors are labeled 12-17 for the corresponding slots on the shelf assembly. Each AMP Champ connector on the backplane supports 14 DS-1 ports for a DS1-14 card, and each connector features 28 live pairs—one transmit pair and one receive pair—for each DS-1 port.
Note
Caution
Table 1-3 shows the pin assignments for the AMP Champ connectors on the ONS 15454 AMP Champ EIA for a shielded DS1 cable.
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.
1.5.5 EIA Replacement
The replacement procedure is the same for all the EIA types. However, installing the AMP Champ EIA requires the additional step of attaching the fastening plate to the bottom of the connector row. Before you attach a new EIA, you must remove the backplane cover or EIA already attached to the ONS 15454.
1.6 Coaxial Cable
Caution
When using ONS 15454 DS-3 electrical cables, the cables must terminate on an EIA installed on the ONS 15454 backplane. 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.
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.
1.7 DS-1 Cable
DS-1s support AMP Champ connector cabling and twisted-pair wire-wrap cabling. Twisted-pair wire-wrap cables require SMB EIAs.
1.7.1 Twisted Pair Wire-Wrap Cables
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
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.
1.7.2 Electrical Interface Adapters
Note
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 1-18 shows the DS-1 electrical interface adapter.
Figure 1-18 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.

Figure 1-19 Managing cables on the front panel
1.8.1 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.
1.8.2 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 (baluns).
1.8.3 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.
1.9 Alarm Expansion Panel
The ONS 15454 alarm expansion panel (AEP) can be used with the AIC-I card to provide an additional 48 dry alarm contacts for the ONS 15454 system, 32 of which are inputs and 16 outputs. The AEP is a printed circuit board assembly that is installed on the backplane. Figure 1-20 shows the AEP board and Figure 1-21 shows a block diagram of the unit.
The AIC-I without an AEP already contains direct alarm contacts. These direct AIC-I alarm contacts are routed through the backplane to wire-wrap pins accessible from the back of the shelf. If you install an AEP, you cannot use the alarm contacts on the wire-wrap pins. For further information about the AIC-I, see the "AIC-I Card" section on page 2-25.
Figure 1-20 AEP printed circuit board assembly
Figure 1-21 AEP block diagram
Each AEP alarm input port has provisionable label and severity, optocoupler isolation, one common 32VDC output for all alarm inputs, and a maximum of 2 mA per input. Each optometal oxide semiconductor MOS alarm output can operate by definable alarm condition, maximum allowed open circuit voltage of 60 VDC, and maximum current of 100 mA. See the "External Alarms and Controls" section on page 2-26 for further information.

ONS15454 cards, when installed in a system, comply with these standards:–
1.10 Fan-Tray Assembly
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. Refer to the Cisco ONS 15454 Troubleshooting Guide for information about cleaning and maintaining the fan-tray air filter.
Note
Caution
Caution
Note
1.10.1 Fan Speed
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, refer to the Cisco ONS 15454 Troubleshooting Guide. 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.

1.11 Air Filter
The ONS 15454 contains an air filter; NEBS 3E and later versions of the ONS 15454 use a reusable air filter that is installed either beneath the fan-tray assembly or in the optional external filter brackets. Earlier versions of the ONS 15454 use a disposable air filter that is installed beneath the fan-tray assembly only.
Warning
1.11.1 Reusable Air Filter
The reusable filter is made of a gray, open-cell, polyurethane foam that is specially coated to provide fire and fungi resistance. NEBS 3E and later versions of the ONS 15454 use a reusable air filter. Spare filters should be kept in stock.
1.11.2 Disposable Air Filter
The disposable filter is made of spun white polyester that is flame retardant. NEBS 3E and earlier versions of the ONS 15454 use a disposable air filter. This disposable filter is not designed to be cleaned. You can order air filter replacements from Cisco (Cisco P/N: 47-01-00001) or from Universal Air Filter Company, model PE-5:

1624 Sauget Industrial Parkway,
Sauget, IL 622061.12 Power and Ground Description
Ground the equipment according to Telcordia standards or local practices.
Cisco recommends the following wiring conventions, but customer conventions prevail:
•
•
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.
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 faulty current that might be imposed.
Note
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 1-25 shows the location of the ground posts.
Figure 1-25 Ground posts on the ONS 15454 backplane
For information about attaching ferrites to power cabling, refer to the "Ferrites" section.
1.13 Alarm, Timing, LAN, and Craft Pin Connections
Caution
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 1-26 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 1-26 shows pinouts for the ONS 15454.

Note
1.13.1 Alarm Contact Connections
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 (external alarm) and ENVIR ALARM OUT (external control) 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 1-26 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.
1.13.2 Timing Connections
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 1-8 lists the pin assignments for the BITS timing pin fields.
Note
1.13.3 LAN Connections
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 1-9 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).
*The Cisco ONS 15454 is DCE.
1.13.4 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 1-10 shows the pin assignments for the CRAFT pin field.

1.14 Cards and Slots
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 1-27 shows card installation.
Figure 1-27 Installing cards in the ONS 15454
1.14.1 Card 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 all ONS 15454 cards, except the OC12/STM4-4 card. 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
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 1-11 shows the slot and card symbol definitions.
Table 1-12 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.
1.14.2 Card Replacement
To replace an ONS 15454 card with another card of the same type, you do not need to make any changes to the database; remove the old card and replace it with a new card. To replace a card with a card of a different type, physically remove the card and replace it with the new card, then delete the original card from CTC.
Caution
