Note In this chapter, the terms "ONS 15327" and "shelf assembly" are used interchangeably. In the installation context, these terms have the same meaning. Otherwise, shelf assembly refers to the physical steel enclosure that holds cards and connects power, and ONS 15327 refers to the entire system, both hardware and software.

1.3 Rack Installation

The ONS 15327 is easily mounted in a 19- or 23-inch equipment rack. The shelf assembly projects 2 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. With the mounting ears attached, the shelf assembly is 19 inches wide.

The ONS 15327 measures 5.1 inches high, 19 or 23 inches wide (depending on which way the mounting ears are attached), and 11 inches deep (13 x 48.3 x 28 cm). Figure 1-1 shows the dimensions of the ONS 15327 shelf assembly.

Figure 1-1 The ONS 15327 shelf assembly dimensions

1.3.1 Reversible Mounting Bracket

Caution Use only the fastening hardware provided with the ONS 15327 to prevent loosening, deterioration, and electromechanical corrosion of the hardware and joined material.
Caution When mounting the ONS 15327 in a frame with a non-conductive coating (such as paint, lacquer, or enamel) use either the thread-forming screws provided with the ONS 15327 shipping kit or remove the coating from the threads to ensure electrical continuity.

The shelf assembly comes with mounting brackets that can be reversed for use with a 19- or 23-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 wider side of the mounting bracket flush against the shelf assembly (see Figure 1-2).

The narrower 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 15327 in a rack requires a minimum of 5.2 inches of vertical rack space (plus 1 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 15327.

Figure 1-3 Mounting an ONS 15327 in a rack

One person can install the shelf assembly using the mounting screws provided. For easier lifting, the shelf should be empty of cards and the fan tray.

Procedure: Mount the ONS 15327 in a Rack

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 rack position.

Step 3 Align the screw holes on the mounting ears with the mounting holes in the rack.

Step 4 Install one mounting screw in each side of the assembly.

You should use at least one set of the horizontal screw slots on the mounting brackets to prevent future slippage.

Step 5 When the shelf assembly is secured to the rack, install the remaining mounting screws.

1.3.3 Mounting Multiple Nodes

Most standard seven-foot racks can hold 12 ONS 15327s and a fuse and alarm panel.

Procedure: Mount Multiple ONS 15327s in a Rack

Step 1 Install the fuse and alarm panel at the top.

Step 2 Mount the first ONS 15327 directly below the fuse and alarm panel.

Step 3 Repeat the procedure with the remainder of the ONS 15327s.

1.4 Fan-Tray Assembly Installation

Facing the front of the ONS 15327, the fan-tray assembly is located on the right-hand side. The fan tray is a removable drawer that holds fans and fan-control circuitry for the ONS 15327. After you install the fan tray, you should not need to remove it unless a fan failure occurs or you need to replace, inspect or clean the fan-tray air filter.

The fan-tray assembly has an air filter on the right side of the fan tray that you can install and remove by hand. Remove and visually inspect this filter every 30 days. For inspection procedures, refer to the "Air Filter Inspection and Replacement" section on page 12-2. Spare filters should be kept in stock. If you are replacing the air filter, you must first move aside the cables that cross in front of it. You must install the air filter with its metal bracing against the fan tray.

Figure 1-4 Removing or replacing the fan-tray air filter

Caution Do not force the fan-tray assembly into place while installing it. Forcing the fan-tray assembly into place can damage the connectors on the fan tray and/or the connectors on the back panel of the shelf assembly.

Procedure: Install the Fan-Tray Assembly

Step 1 If cables are installed, move them away from the fan tray slot.

Step 2 Slide the fan tray into the shelf until the electrical plug at the rear of the tray plugs into the corresponding receptacle on the backplane.

Step 3 Secure the fan tray into the slot using the attached fastening screw.

Step 4 After power is supplied, confirm that the FAN STATUS LED on the front of the fan tray is illuminated. This indicates that the fan tray is operating.

The FAN STATUS LED only illuminates when an XTC card is installed.

Figure 1-5 shows the location of the fan tray.

Figure 1-5 Installing the fan-tray assembly

Procedure: Remove the Fan-Tray Assembly

Step 1 Move cables away from the fan tray slot.

Step 2 Loosen the fastening screw.

Step 3 Grasp the fan tray handle and gently pull it out of the fan tray slot ( Figure 1-6)

Figure 1-6 Removing a fan-tray assembly with installed cables

If the fan fails on the fan-tray assembly, replace the entire assembly. You cannot replace an individual fan. The FAN STATUS LED turns red when one or more fans fail. For a procedure that replaces the fan tray, see the "Install the Fan-Tray Assembly" section.

1.5 Power and Ground Installation

This section describes how to connect the ONS 15327 shelf assembly to the power supply. Terminate the chassis ground to either the office ground or rack ground before you install the power. Use the grounding lug to attach the ground cable to the shelf assembly according to local site practice.

Warning This equipment must be grounded.

Warning When installing the node, you must connect the ground first and disconnect it last.

You only ground one cable to ground the shelf assembly. Terminate the other end of the rack ground cable to ground according to local site practice.

If the system loses power or both XTC cards are reset, you must reset the ONS 15327 clock unless the node has been previously provisioned to use Simple Network Time Protocol (SNTP) to update the clock over the LAN.

Warning Do not apply power to the ONS 15327 until you complete all installation steps.

Warning Before performing any of the following procedures, ensure that the power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.

Caution Always use the supplied ESD wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.

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.

Use the following wiring conventions:

•Red wire for battery (-48V DC) connections

•Black wire for battery return (0V DC) connections

Note Use an external disconnect for service purposes and install it according to local site practice.

The ONS 15327 has redundant -48V DC power terminals on the MICs. The terminals are labeled PWR A and PWR B and are located on the far right-hand side of the MICs if you are facing the shelf assembly. Both MIC A and MIC B must be installed to create redundant power connections.

To install redundant power feeds, use four power cables and one ground cable. For a single power feed, only two power cables and one ground cable are required. Use #12 AWG cable and, to ensure circuit overcurrent protection, use a conductor with low impedance. However, the conductor must have the capability to safely conduct any fault current that might be imposed. Do not use aluminum conductors.

The MIC power connector is shipped with the fastening screws inserted but not tightened. The screws may have tightened due to vibration during shipping. Make sure the screws are loose before attempting to remove the connector.

Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring.

Warning Connect the unit only to DC power source that complies with the Safety Extra-Low Voltage (SELV) requirements in IEC 60950 based safety standards.

Procedure: Install Redundant Power Feeds

Step 1 Terminate the chassis ground to either the office ground or rack ground.

The ground connection point is located on the left-hand side panel as you face the ONS 15327.

Note To ensure that the equipment is properly grounded, use the provided 12 AWG dual-hole grounding lug and the #10-32 x 3/8 pan head phillips power lug screws to connect the ground cable to the chassis. Apply 30-36 in.-lbs of torque when tightening the screws.

Step 2 Measure and cut the cables as needed to reach the ONS 15327 from the fuse panel. Use the correct size fuse for each power lead.

Step 3 Dress the power and ground cables according to local site practice.

Warning When installing the node, the ground connection must always be made first and disconnected last.

Step 4 Strip .22 inches of insulation from all power cables that you connect to the ONS 15327 power connectors.

Step 5 Install MICs in Slots 7 and 8.

See the "Card Installation and Turn-Up" section for installation in instructions.

Warning Do not expose more than .22 inches of bare wire on power cables.

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 in this manner, but always keep them clean and free of contaminants.

Step 6 Remove the connector from the slot by grasping it with your fingers and gently pulling it. If you cannot remove it easily, you can use a pair of needle nose pliers and grab it by the center of the channel. Figure 1-7 shows the MIC power connector being removed.

Figure 1-7 Removing the MIC power connector

Step 7 Remove the cable fastening screws (the screws on the top of the connector that become visible when the connector is removed).

Step 8 Insert the return (black) wire into the right hand (RTN) slot of the connector. Figure 1-8 shows a power cable being inserted into the MIC power connector.

Figure 1-8 Inserting a power cable into the MIC power connector

Step 9 Replace the cable fastening screw for the return (RTN) wire and tighten with a small slot head screwdriver.

Step 10 Insert the battery (red) wire into the left hand (-48V) slot of the connector.

Step 11 Replace the cable fastening screw for the battery (-48V) wire and tighten with the screwdriver.

Step 12 Insert the connector back into the slot on the MIC and tighten the screws with the screwdriver. Figure 1-9 shows the MIC power connector being installed.

1.5.1 Ferrite Installation

Place third-party ferrites on power cables to dampen electromagnetic interference (EMI) from the ONS 15327. 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.

Procedure: Attach Ferrites to Power Cabling

Use a single block ferrite Fair Rite 0443164151 for each pair of cables.

Step 1 Wrap the cables once around and through the block ferrites.

Step 2 Place the block ferrite within 5 to 6 inches of the power terminals.

1.6 Alarm Cutoff

Visual and audible alarms are typically wired to trigger an alarm light at a central alarm collection point when the corresponding contacts are closed. The alarm cutoff (ACO) function stops (turns off) the alarm signal being transmitted to the alarm collection point.

To activate the ACO function, press the ACO button on the XTC card faceplate. The ACO button clears all audible alarm indications. After clearing the audible alarm indication, the alarm is still present on the Alarms tab in Cisco Transport Controller (CTC) and appropriate action is needed to clear the alarm. For information about connecting to alarm collection equipment, See the "Alarm Cable Installation" section. For procedures that resolve alarms, refer to Chapter 14, "Alarm Troubleshooting."

1.7 Timing Installation

The ONS 15327 supports two Building Integrated Timing Supply (BITS) clock interfaces. The physical connection is provided through an RJ-45 connector on each MIC. Two pins on each RJ-45 are used for BITS timing. BITS 1 In (MIC A) and BITS 2 In (MIC B) use pins 3 and 4. BITS 1 Out (MIC A) and BITS 2 Out (MIC B) use pins 7 and 8. The BITS 1 pins support output and input from the first external timing device. The BITS 2 pins perform the identical functions for the second external timing device. Table 1-2 lists the pin assignments for the BITS timing pin fields. For more information about connecting BITS timing to the ONS 15327, See the "BITS Cable Installation" section.

1.8 Card Installation and Turn-Up

Caution Always use the supplied ESD wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.

ONS 15327 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 1-11 shows XTC card installation (which is the same as MIC installation) and Figure 1-12 shows high-speed card installation.

Warning The optical cards for the ONS 15327 are Class 1 laser products. These products have been tested and comply with Class 1 limits.

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 to avoid the risk of shock.

Note DS-1 and DS-3 interfaces are not intended for direct connection to the network. These interfaces should be connected to the network via a CSU/DSU that has the proper certification.

1.8.1 Slot Requirements

The ONS 15327 shelf assembly has eight card slots; four high speed slots, two Cross-Connect, Timing and Control (XTC) slots, and two Mechanical Interface Card (MIC) slots. The wider slots host the XTC cards and MICs. The narrower, high-speed slots host Ethernet, OC-3, OC-12, and OC-48 cards.

The XTC slots host both XTC-14 and XTC-28-3 cards. XTC cards are required for system operation. The MIC slots host MIC A and MIC B cards. The MIC slots are keyed to ensure that you install the MICs in the correct slot. Install MIC A in the bottom MIC slot (Slot 8) and MIC B in the top MIC slot (Slot 7). MICs are also required for system operation. Make DS-1 and DS-3 connections using the connectors on the MICs. Refer to Chapter 13, "Card Reference," for more information about ONS 15327 cards.

1.8.2 Card Turn-Up

The procedure for turning up ONS 15327 cards is slightly different for each card. Before installing any XTC or high-speed cards, install at least one MIC and apply power to the shelf assembly. First install MIC A in Slot 8. After successfully connecting the power to MIC A, install MIC B followed by the XTC cards. Install any high-speed cards after you have successfully installed and turned up the XTC cards and MICs. Follow the steps in this section to verify card turn-up.

The card turn-up procedures reference the slot numbers for the ONS 15327. Figure 1-13 shows the location and corresponding number of each slot.

Figure 1-13 ONS 15327 slot numbering

Note Because all high-speed cards boot from the working XTC card, at least one XTC card must be installed in order to boot any high-speed cards.

Warning Invisible laser radiation can be emitted from the aperture port when no cable is connected. To avoid exposure to laser radiation and do not stare into open apertures.

Procedure: Verify Successful Turn-Up of MICs

Step 1 Install MIC A in Slot 8.

The slots are keyed to ensure that cards are installed in the correct slot.

Step 2 Verify that the power and ground cables are installed correctly.

Step 3 With power applied to MIC A, insert the fan-tray assembly and verify that the fans activate.

The fans will only activate if at least one XTC card is installed.

Step 4 If you require redundant power, more than 14 DS-1s, or you are using DS-3s, install MIC B in Slot 7. If MIC B is not required, proceed to Step 7.

Step 5 With power applied to MIC B, unplug MIC A from the backplane (do not remove it completely) and verify that the fans are still running.

Warning Disconnect power before removing MICs from the ONS 15327.

Step 6 Plug MIC A back into the backplane and reconnect power.

Step 7 Verify that the card appears in the correct slot on the CTC node view (default login) screen.

Step 8 Verify that the card is white on the CTC node view screen.

Step 9 If MIC A was unplugged in Step 5, plug it back into the backplane and verify that it appears in the correct slot and is white on the CTC node view screen.

Refer to Chapter 2, "Software Installation," for more information about using CTC.

Procedure: Verify Successful Turn-Up of XTC Cards

Step 1 Install an XTC in Slot 6.

Slot 6 is the working XTC slot.

Step 2 Verify that the red FAIL LED blinks for approximately 30 seconds.

Step 3 Verify that all LEDs blink once and turn off.

Step 4 Verify the ACT/STBY LED is green (active).

Step 5 Install the second XTC in Slot 5.

Slot 5 is the protect XTC slot.

Step 6 After the LED boot sequence (Steps 3 and 4), verify that the ACT/STBY LED is yellow. The yellow LED indicates that the second XTC is the standby XTC.

Step 7 Press the LAMP TEST button on the faceplate of each XTC and verify that all LEDs illuminate while you press the button.

Step 8 Verify that the card appears in the correct slot on the CTC node view screen.

1.9 Cable Description and Installation

This section explains how to install fiber-optic, DS-3 (coaxial), DS-1 (CHAMP), and twisted-pair cables.

1.9.1 Cabling Types

ONS 15327 cables use cable guides at each side of the front of the shelf assembly to economize shelf space and facilitate cable management. The following types of cables are used with the ONS 15327:

•Optical Cables: Optical cables connect to the SC connectors on the faceplate of the OC-12 and OC-48 cards and the LC connectors on the OC-3 cards (described in the "Fiber Cable Installation" section). Make sure the fiber cables do not bend excessively; maintaining a proper bend radius prevents damage to the optical cable.

•Coaxial Cables: Coaxial cables connect to the MICs on the ONS 15327 using BNC cable connectors. Coaxial cables carry DS-3 traffic to and from the ONS 15327. The ONS 15327 supports up to three transmit and three receive coaxial connectors on each shelf assembly.

•CHAMP Cables: CHAMP cables connect to MICs on the ONS 15327 using CHAMP cable connectors. Each CHAMP connector on the MIC supports one CHAMP cable connection for a total of two connectors per node. Each CHAMP connector supports a maximum of 14 DS-1s. See the "DS-1 Cable Installation" section for more information about the CHAMP cables and connectors.

•Twisted-pair Cables: Twisted-pair cables connect to the ports on the Ethernet card, the Alarm and BITS ports on the MICs, and the LAN port on the XTCs. The twisted-pair cables use RJ-45 connectors. The Ethernet card ports and the LAN ports use a standard straight-through cable. Connecting to either the BITS or Alarm ports requires special cables described in the "Alarm Cable Installation" section and the "BITS Cable Installation" section.

1.9.2 Cable Installation Overview

Because the ONS 15327 supports a large number of interfaces on the front panel, proper cable management and the correct cabling sequence during installation are required.

1.9.2.1 Cable Guides

The ONS 15327 has cable guides located on each side of the front of the shelf assembly. The cable guides ensure that the proper bend radius is maintained in the fibers and that all other cables are properly routed. To remove cable guides, take out the screws that anchor them to the side of the shelf assembly.

Figure 1-14 Managing front panel cables with locking cable guides

1.9.2.2 Cabling Sequence and Location

The two cable management considerations are the sequence of cable installation and the location of cable routing. To maintain access to all of the connectors during cable installation, cables must be attached to the MICs in the following order starting with MIC A (the bottom MIC) and repeating for MIC B:

1. Attach power cables

2. Attach DS-1 (CHAMP) cables

3. Attach Alarm (RJ-45) cables

4. Attach BITS (RJ-45) cables

5. Attach DS-3 (BNC) cables

After attaching all of the cables to the MICs, route the cables out through the bottom right cable guide and snap it closed. Tie wrap the cables according to local site practice. Leave enough slack to remove the fan-tray assembly and fan filter.

You do not need to connect cables for the XTCs and high-speed cards in any particular order. Route XTC cables through the top right cable guide. Route high-speed cables out through the corresponding cable guides on the left-hand side of the shelf assembly. Figure 1-15 shows the order in which you should install cables on the ONS 15327.

Figure 1-15 The cable installation sequence

1.9.3 Fiber Cable Installation

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.

ONS 15327 OC-12 and OC-48 cards have SC connectors and the OC-3 cards have LC connectors. To install fiber-optic cables in the ONS 15327, a fiber cable with the corresponding connector type must be connected to the transmit and receive ports on the ONS 15327 cards. On ONS 15327 OC-12 and OC-48 card ports, the left-hand connector is the transmit port and the right-hand connector is the receive port. Cisco recommends that you label the transmit and receive ports and the working and protection fibers at each end of the fiber span to avoid confusion with cables that are similar in appearance.

Warning Invisible laser radiation can be emitted from the aperture port when no cable is connected. To avoid exposure to laser radiation do not stare into open apertures.

Procedure: Install and Route Fiber-Optic Cables in the ONS 15327

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 1-16 shows the cable location.

Note Clean all fiber connectors thoroughly. Dust particles can degrade performance. Put caps on any fiber connectors that you do not use.

Figure 1-16 Installing a fiber-optic cable

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.

Step 4 Route fiber cables out through the cable guides on the side of the shelf assembly.

See the "Cable Guides" section for more information about cable management.

1.9.4 Coaxial Cable Installation

DS-3s connect to the ONS 15327 using coaxial cables and connectors. Cisco recommends connecting an RG-59/U cable to a patch panel; RG-59/U cable is designed for long runs of up to 450 feet. Use a compatible straight male BNC connector to connect the cable to the DS-3 ports on the MICs. The transmit (TX) ports on MIC A and the receive (RX) ports on MIC B use the same type of connector.

Caution Always use the supplied ESD wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.

Procedure: Install Coaxial Cable With BNC Connectors

Step 1 Place a BNC cable connector over the desired connector on the MIC.

Figure 1-17 shows how to connect a coaxial cable to the ONS 15327 MIC.

Figure 1-17 Installing a coaxial cable with BNC connectors

Step 2 Position the cable connector so that the slot in the connector is above the corresponding notch on the MIC connection point.

Step 3 Gently push the connector down until the notch on the MIC connector slides into the slot on the cable connector.

Step 4 Turn the cable connector until the notch clicks into place.

Step 5 Route the cables to the nearest side of the shelf assembly through the side cutouts according to local site practice.

Label all cables at each end of the connection to avoid confusion with cables that are similar in appearance.

1.9.5 DS-1 Cable Installation

DS-1s support CHAMP connector cabling. This section provides information about the DS-1 cables and connectors.

Installing CHAMP connector DS-1 cables requires 64-pin bundled cable connectors with a 64-pin female CHAMP connector. You need CHAMP connector #552276-1 for the receptacle side and #1-552496-1 for the right-angle shell housing, or their functional equivalents. The corresponding 64-pin male CHAMP connector on the MIC supports one receive (in) and one transmit (out) for each DS-1 port for the corresponding XTC.

Because each DS1-14 connection 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 connection. Table 1-4 shows the pin assignments for the CHAMP connectors on the ONS 15327 MICs.

Figure 1-18 Installing a DS-1 cable

1.9.6 Alarm Cable Installation

The alarm cables attach to the MICs using twisted-pair cables terminated with an RJ-45 connector on the end that plugs into the ALARM port. The other end of the cable plugs into the alarm-collection equipment. Terminate this end of the cable according to local site practice.

The pins on the ALARM port correspond to the six external alarm inputs and the two external alarm outputs (controls) that can you can define using CTC (for procedures, refer to the "Using Virtual Wires" section on page 7-17). Alarms 2, 4, and 6 correspond to MIC A and alarms 1, 3, and 5 correspond to MIC B. Alarm output 1 corresponds to MIC B and alarm output 2 corresponds to MIC A. Table 1-5 shows the input alarm pinouts and the corresponding alarm numbers assigned to each MIC/port. Table 1-6 shows the output alarm pinouts. Refer to these tables when connecting alarm cables to the ONS 15327. See Figure 1-19 for RJ-45 pin numbering.
