TSR II Bay Module Population Rules

Each TSR bay has four shelves numbered from 1 (top) to 4 (bottom). Each shelf has 11 slots to house the router and server modules. All router modules must be inserted in pairs.

TSR II Bay, Shelf, and Slot Numbering

All bays are numbered odd in the first row; for example: 1 and 3 and even in the second row; for example: 2 and 4 (refer to Figure 1).

Figure 1. Bay Numbering

The four shelves and their slots are numbered as follows:

Figure 2. TSR II Bay Shelf and Slot Numbering

Populating the Bay

The location of the routing modules within the bay creates the TSR system's "toroidal mesh." It is critical to install routing modules and server modules in predefined positions. All router modules must be inserted in pairs.

Slots are labeled with red circles to help you identify the module for that slot. The TSR II ONLY accepts a red module.

The rules for populating the first TSR II Full Bay and TSR II Split Bay with module pairs are as follows:

Refer to IPriori CLI Reference and Configuration Guides (Vol. 1) for further information on this command. Online versions of the manuals are available at http://www.avici.com/documentation.

Preparing to Install Modules

Depending on the individual configuration of the TSR II, either a router module or a filler module must be removed in order to install this module set. Refer to "Removing Router Module(s)" to remove a router module and refer to "Removing Filler Modules" to remove a filler module.

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 II 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 TSR bay shelf (refer to Figure 3).

Step 3 Use the ESD jack while handling modules.

Figure 3. ESD Jack Location

Removing Router Module(s)

If it is necessary to remove existing router modules, the router module must be shutdown before removing.

To notify the system to shutdown a module, use the CLI command line to turn off the respective slot. Using the shutdown command allows the removal of the module without service interruption. For specific instructions on the shutdown command, refer to the IPriori CLI Reference, (Vol. 1). After module replacement, use the CLI command line to turn on the respective slot.

CAUTION (1) When handling modules, wear a grounded wrist strap or equivalent antistatic protection to prevent damage to electronic parts.

Routine router module removal requires the disconnecting of existing fiber optic cable connections. Router modules serving as Server Attached Modules (SAMs) require disconnecting fiber optic and Ethernet cable connections to the server module.

CAUTION (2) Within five minutes of removal of a module, a replacement module or filler module must be installed in the empty slot to ensure proper air flow within the system.

Shutting Down the Module

Use the shutdown command to disable all functions on the module. The module appears as administratively down when executing the show mod brief command.

Example:

router(config)#interface gbe 1/34/1

router(config-if)#shutdown

router(config-if)#end

router#

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

CAUTION (3) When handling modules, wear a grounded wrist strap or equivalent antistatic protection to prevent damage to electronic parts (see "Preparing to Install Modules" ).

Step 1 Open the pull tab on the center cable tray and gently pull the center cable tray out of the router (see Figure 4 and Step 5).

Figure 4. Router Module Faceplate

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.

Step 2 Disconnect the lower fiber optic cables from the fiber cable adapters (SC) on the center cable tray. Move the cables to one side to ensure that they do not interfere with removal of the router module (see Figure 5).

Figure 5. Router Module Cable Connections

Step 3 Gently push the center cable tray back into the router module and close the cable tray pull tab. If necessary, repeat Step 1 through Step 2 for fiber optic cable connections in the right cable tray.

If the module is a SAM, proceed to Step 4, if not then skip to Step 5.

Step 4 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 5 Open the pull tab on the center cable tray and gently pull the cable tray out of the router until detent clicks (see Figure 6).

Figure 6. Ethernet Cable Connection

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

Step 7 Hang the Ethernet cable down and out of the way, or tuck the cable into the horizontal cable tray under the module shelf.

Step 8 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 9 To unlock the ejector latches, simultaneously slide the release levers in the direction of the arrows (see Figure 7).

Figure 7. Router Module Removal

Step 10 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).

CAUTION (4) 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 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 12 To remove the module, grasp it on the top and bottom and pull it carefully out of the shelf.

A detailed inspection of the VDHM 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 (5) Any contact to a VHDM connector outside a TSR II could damage the connector.

Step 13 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 TSR II. Mark the module and slot as damaged and call TSR-BY-AVICI to request an Request Material Authorization (RMA).

Step 14 Before placing the module in a static-proof bag, replace the VHDM protective cap over the VHDM connector at the rear of the module. This will protect the pins while the module is not in the TSR II (see Figure 12). Repackage according to RMA directions. Ship back to Avici.

Step 15 If the slot is not populated with a module, it must be filled with a filler module within five minutes.

Removing Filler Modules

The TSR II systems ships with 38 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).

If you are removing a filler module from the TSR II, use the following procedure.

Figure 10. Filler Module

PROCEDURE: Use the following steps 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 Router Modules

When replacing a router module or a filler module, installation must adhere to module population rules for your type of installation. Refer to the Terabit Switch Router Series II Install Guide (Single Bay) and Field Replacement Procedure that came with the module and "TSR II Bay Module Population Rules" .

Installation of the Server Attached Module (SAM) requires the re-connection of fiber optic and Ethernet cables.

CAUTION (6) When handling modules, wear a grounded wrist strap or equivalent antistatic protection to prevent damage to electronic parts.

PROCEDURE: Use the following procedure when installing a router module or a Server Attached Module (SAM):

Step 1 Remove the router module from its packaging and static protection bag.

Step 2 Before inserting the module, remove the VHDM protective cap from the end of the module before use. Set the protective cap aside in a safe place (see Figure 12).

Figure 12. Remove VHDM Protective Cap Before Use
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 (see Figure 13).
