Overview

The Single-Port Dual Slot OC-192c/STM-64c module consists of a pair of modules, a 10 Gigabit optical output module (STM64/OC192a) and a companion module (STM64/OC192b) that are interconnected via a high speed, coaxial ribbon cable.

NOTE To visually identify this module set, please refer to the faceplate labels. The 10 Gigabit optical output module can be identified by STM64/OC192a and the companion module can be identified by the label STM64/OC192b.

This OC-192c module set provides a short reach, intra-office, SONET/SDH OC-192c/STM-64c interface to both edge routers and long-haul inter-office transmission equipment such as OXCs and DWDM muxes. This module set includes MPLS.

Optical Interfaces

This Single-Port Dual Slot OC-192c module pair supports Telcordia Single Mode Short Reach SR-1 compliant optics as described in GR-253-CORE, Issue 3 and ITU-T Draft Rec. G.691 (refer to Table 1).

SSR Module Population Rules

Each SSR chassis has two shelves numbered 1 (top) and 2 (bottom). Each shelf has 11 slots to house the router and server modules. Each shelf can house one server module and 10 router modules. The server modules can only be placed in the left most slot on each shelf, slots (S1 and S2). The router modules occupy slots 1-10 and 11-20. All router modules must be inserted in pairs.

SSR Chassis Shelf and Slot Numbering

The two shelves and their slots are illustrated in Figure 1.

Figure 1. SSR Chassis Shelf and Slot Numbering

Module Orientation For OC-192c

Slots are labeled with red circles and blue squares to help you identify how to orient the module for that slot. For this dual module set, there are two modules that make up the pair, a 10 Gigabit optical output module (STM64/OC192a) and a companion module (STM64/OC192b) that are interconnected via a high speed, coaxial ribbon cable:

Populating The First Chassis

The rules for populating the first SSR chassis with module pairs are as follows:

Populating The Second Chassis

The population rules for the second chassis are the same as for the first.

The OC-192c module set needs to be populated in the manor depicted in Figure 2.

NOTE With the Single-Port Dual Slot OC-192c module set, the pairs consist of one of each type of module. For example, slot 15 will hold a STM64/OC192b and slot 16 will hold a STM64/OC192a. This dual module set is the pair. The next two modules will then take the reverse position. For example, slot 05 will be populated with a STM64/OC192a and slot 06 will take a STM64/OC192b.

Figure 2. Population Rules for OC-192c Module Sets

Preparing to Install Modules

This section describes the procedure to prevent damage to the SSR system from static electricity.

Use these precautions to prevent damage from static electricity:

Installing the Antistatic Wrist Strap

A grounded antistatic wrist strap must be used to protect the TSR system modules and components from damage caused by static.

PROCEDURE: Use the following procedure to install the antistatic wrist strap:

Step 1 Remove the alligator clip from the grounding pin on the antistatic wrist strap.

Step 2 Insert the grounding pin into the electrostatic discharge (ESD) jack on the front of the SSR chassis shelf. (see Figure 3).

Step 3 Use the ESD jack while handling modules.

Figure 3. ESD Jack Location

Removing Router Modules

Prior to removing a module you must shut down the module being replaced.

PROCEDURE: Use the following steps to remove the Gigabit Ethernet module(s):

Step 1 Verify that the antistatic wrist strap you are wearing is properly grounded.

Step 2 Open the pull tab on the right cable tray and gently pull the right cable tray out of the router (see Figure 4).

.

Figure 4. Router Module Faceplate

Step 3 Disconnect the lower fiber optic cables from the fiber cable adapters (SC) on the right cable tray. Move the cables to one side to ensure that they do not interfere with removal of the router module (see Figure 5).

WARNING (1) This is a Class 1 laser product. Invisible laser radiation can be emitted from the aperture of the port when the fiber cable is disconnected. Avoid exposure to laser radiation and do not look directly into open apertures.

Figure 5. Router Module Cable Connections

Step 4 Gently push the right cable tray back into the module and close the cable tray pull tab.

If the module is a SAM, proceed to Step 5, if not then skip to Step 10.

Step 5 Open the cable tray pull tab on the faceplate of the router module tray marked "AUX." Gently pull the cable tray partially out of the module until detent clicks (see Figure 6).

Step 6 Open the pull tab on the center cable tray and gently pull the cable tray out of the router until detent clicks.

Figure 6. Ethernet Cable Connection

Step 7 Disconnect and undress the RJ-45 Ethernet cable from the Ethernet port on the tray marked "AUX." (see Figure 6).

Step 8 Hang the Ethernet cable down and out of the way, or tuck the cable into the horizontal cable tray under the module shelf.

Step 9 Gently push all cable trays to the closed position and close the cable tray pull tabs.

WARNING (2) This is a Class 1 laser product. Invisible laser radiation can be emitted from the port aperture when the fiber cable is disconnected. Avoid exposure to laser radiation and do not look directly into open apertures

Step 10 To unlock the ejector latches, simultaneously slide the release levers in the direction of the arrows (see Figure 7).

CAUTION (1) When the ejector latch release lever is in the open position, do not use the latch lever to remove the module or adjust the module in the card guides. Failure to adhere to these guidelines may result in equipment damage.

Step 11 To release the module from the backplane, simultaneously rotate the ejector latches to a fully open position and carefully pull the router out a few inches out of the shelf (see Figure 7).

Figure 7. Router Module Ejector Release Levers

Step 12 Hold module in place with one hand at the bottom of case, then close the ejector latches by rotating them to the closed position and sliding the release levers in the direction of the arrows to lock the levers back into place.

Step 13 To remove the module, grasp it on the top and bottom and pull it carefully out of the shelf.

A detailed inspection of the Very High Density Metric (VHDM) connector is required each time a module is removed or inserted. Lay the module gently on its side to perform a VHDM connector inspection.

NOTE Do not rest the module on the cable trays during inspection. This could result in the breaking of the pull tabs on the cable tray drawers (see Figure 8).

Figure 8. Cable Tray Pull Tab

CAUTION (2) Any contact to a VHDM connector outside a SSR could damage the connector.

Step 14 Carefully inspect the VHDM connector for damage such as deformed sockets, holes between socket columns, and deformed guide fins on top and bottom of the socket columns.

.

Figure 9. VHDM Connector

NOTE If the VHDM connector has any signs of damage, DO NOT insert it into a SSR. Mark the module and slot as damaged and call TSR-BY-AVICI to request an Return Material Authorization (RMA).

Step 15 Before placing the module in a static-proof bag, replace the VHDM (Very High Density Modular) protective cap over the VHDM connector at the rear of the module. This will protect the pins while the module is not in the SSR. Refer to Figure 12. Repackage according to RMA directions. Ship back to Avici.

Step 16 If the slot is not populated with a module, it must be filled with a filler module within five minutes.

Removing Filler Modules

The SSR chassis ships with 19 filler modules, which ensures proper cooling and elimination of electromagnetic interference during operation. Remove filler modules from slots intended for router modules (see Figure 10).

Figure 10. Filler Module

Removing Filler Modules

PROCEDURE: Use the following procedure to remove a filler module:

Step 1 Use a 1/2-in. flat-blade screw driver to loosen the lock latch on the filler module.

Step 2 Pull the filler module out of the slot (see Figure 11).

Step 3 Store the filler module in a dry, cool area.

Figure 11. Removing Filler Modules

Installing the Single-Port Dual Slot OC-192c Module

Install the Single-Port Dual Slot OC-192c modules after removing the filler modules. These modules must be installed in assigned slot locations. The two module set is interconnected via a high-speed, electrical coaxial ribbon cable that is shipped detached and assembled by field personnel at the time of installation.

NOTE With the Single-Port Dual Slot OC-192c module set, the pairs consist of one of each type of module. For example, slot 35 will hold a STM64/OC192b and slot 36 will hold a STM64/OC192a. This dual module set is the pair. The next two modules will then take the reverse position. For example, slot 25 will be populated with a STM64/OC192a and slot 26 will take a STM64/OC192b.

Avici Supplied Cables for OC-192c Module Set

Avici supplies a cable kit with each OC-192c module set. Refer to Table 2. These cables can also be purchased as a separate spares kit.

Table 2. OC-192c Cable Kit
Description Quantity Connection Points

80 position shielded coaxial ribbon cable assembly

Each cable interconnects the dual modules via a Low Force Helix (LFH) socket located in the bottom of cable management tray 3-4. This cable allows the dual modules to operate as a single unit.

NOTE When the ejector latch release lever is in the open position, do not use the lever to lift or adjust the module in the card guide.

PROCEDURE: Use the following procedure to install the OC-192c modules:

Step 1 Verify that the antistatic wrist strap you are wearing is properly grounded.

Step 2 Remove the Single-Port Dual Slot OC-192c module from its static protection packaging.

Step 3 Before inserting the module, remove the VHDM protective cap from the end of the module. Set the protective cap aside in a safe place (see Figure 12).

Figure 12. Remove VHDM Protective Cap Before Use

CAUTION (3) Any contact to a VHDM connector outside a SSR could damage the connector.

A detailed inspection of the VHDM connector is required prior to insertion. Lay the module gently on its side so you can perform a VHDM connector inspection.

NOTE Do not rest the module on the cable trays during inspection. This could result in the breaking of the pull tabs on the cable tray drawers.

Step 4 Carefully inspect the VHDM connector for damage such as deformed sockets, holes between socket columns, and deformed guide fins on top and bottom of the socket columns (see Figure 13).

.

Figure 13. VHDM Connector

NOTE If the VHDM connector has any signs of damage, DO NOT insert it into a SSR. Mark the module and slot as damaged and call TSR-BY-AVICI to request an RMA.

Step 5 Check the color indicator on the top of the module to determine if it is the right type for this slot, the SSR only accepts red modules. If it is not the correct color and there is no other slot of that color expecting a module of this type, contact Avici Customer Service, (See "Support Services"). Ensure that the cable trays on the router module being inserted and on the adjacent router modules are fully closed.

Step 6 Close the ejector latches completely by sliding the release levers in the direction of the arrows and locking into place (see Figure 14).

Figure 14. Router Module Installation

Step 7 Aligning the module with the card guides, in the slot, slide the first module into the slot halfway, repeat for second module.

NOTE Single-Port Dual Slot OC-192 modules are inserted as pairs. After inserting STM64/OC192a halfway, insert STM64/OC192b halfway into its slot.

Step 8 Open center and outside cable management trays on both modules.

Step 9 Attach the intermodule coaxial ribbon cable plug (80 pin) to the STM64/OC192a module Low Force Helix (LFH) socket located in the bottom of cable management tray 3-4. Once the cable is attached, tighten the M2 screws. Next, attach the opposite plug from this cable to the corresponding STM64/OC192b module socket and tighten the M2 screw (see Figure 15 and Figure 16).

slot: Slot number where the module is installed in the SSR. Valid values are integers between 1 and 40.

port: Valid values are 1.

Description: The interface pos command defines a POS interface and enters the interface configuration mode. The interface is not usable as a routing interface until you use the ip address and no shutdown commands. In the case of the dual slot OC-192c interface, both modules of the set must be activated before you can configure the interface.

To configure a POS interface:

Configuring a POS Interface

NOTE Be aware that the default for industry-standard routers is to obtain their clock from line. If both ends of the fiber are configured to recover the clock from line, the connection does not work, characterized by SONET failing to come up.

Be sure to include the clock source internal command in your configuration file when configuring the TSR to interoperate with industry-standard routers.

PROCEDURE: To configure a POS interface, use the following steps:

Step 1 Use the interface pos bay#/slot#/port# command name the POS interface and enter Interface Configuration command mode.

Step 2 Use the ip address to assign an IP address to the interface.

Step 3 Use the clock source internal command to select the internal clock of the interface for transmissions.

Step 4 Use the no shutdown command to enable the interface.

Step 5 Use the show interface pos bay#/slot#/port# command to display the interface:

router(config)#interface pos 1/1/1

router(config-if)#ip address 5.10.1.2 255.255.0.0

router(config-if)#clock source internal

router(config-if)#no shutdown

router(config-if)#exit

router(config)#show interface pos 1/1/1
POS 1/1/1 is up, line protocol is down
