Optical Characteristics
The 4-Port OC-12c and the 2-Port OC-48c modules support Telcordia Single Mode Short Reach SR-1 compliant optics as described in GR-1377-CORE, compatible with SR-1 and GR-253 and I-64.1 of ITU G.691. Refer to Table 1 and Table 2.
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 shelves and slot numbering for the SSR is shown in Figure 1.
Populating The Chassis
The rules for populating the first and second SSR chassis with module pairs are as follows:
- Modules occupying a slot use the slot number as its identifier. A module is identified by chassis number/slot number; i.e., 1/10 would be chassis 1, slot 10.
- SSRs accept only red modules. The module color label is located on the top side of the module and on each shelf
- This router module is a Family 1 module.
- Router modules must be added in Family pairs. That is, you must install two Family 1 modules OR two Family 2 modules
NOTE Do not insert router modules into a dedicated server module slot as this may damage the VHDM connector. If you accidentally insert a router module into a dedicated server slot, you must inspect the VHDM connector for damage prior to inserting the module into a module slot.
- If installing the module in a cold bay, follow the Population Rules outlined in the Stackable Switch Router Series II Install Guide.
- If installing the router module in a live bay use the show population CLI command--specifying the module family--to identify the slot to populate.
Refer to Ipriori CLI Reference Guide (Vol. 1) for further information on this command.
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:
- Do not handle modules unless you are using the appropriate antistatic protection, such as an antistatic wrist or heel strap and a conductive mat.
- When using an antistatic wrist strap, attach the cord to the appropriate ground jack (see Figure 1).
- Handle modules by outer enclosure only. Do not touch electrical connections, pins, or soldered surfaces.

Removing Filler Modules
The SSR systems ships with 18 filler modules, which ensures proper cooling and elimination of electromagnetic interference during operation. Remove filler modules from slots intended for router modules (see Figure 2).
Figure 2. Filler Module
If you are removing a filler module from the SSR, use the following procedure.
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 3).
Step 3 Store the filler module in a dry, cool area.

Removing a Router Module
Router module replacement requires shutting down the module via the CLI command line, disconnecting the cable connections, and removing the router module.
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.
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 (1) 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.
Prior to removing a module you must shut down the module being replaced (see ."Removing a Router Module" ).
CAUTION (2) When handling router modules, wear a grounded wrist strap or equivalent antistatic protection to prevent damage to electronic parts (see "Preparing to Install Modules" ).
PROCEDURE: Use the following steps to remove the router module(s):
Step 1 Verify that the antistatic wrist strap you are wearing is properly grounded.
Step 2 Open the pull tab on the center cable tray and gently pull the center cable tray out of the router (refer to Figure 4 and 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 4. Router Module Faceplate
Step 3 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 (refer to Figure 5).
Figure 5. Router Module Cable Connections
Step 4 Gently push the center cable tray back into the router module and close the cable tray pull tab. If necessary, repeat Step 2 through Step 3 for fiber optic cable connections in the right cable tray.
- If the module is a SAM, proceed to Step 5, if not then skip to Step 6.
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 (refer to Figure 6).
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 6 Open the pull tab on the center cable tray and gently pull the cable tray out of the router until detent clicks (refer to Figure 6).
Figure 6. Ethernet Cable Connection
Step 7 Disconnect and undress the RJ-45 Ethernet cable from the Ethernet port on the tray marked "AUX" (refer 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.
Step 10 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 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).
CAUTION (3) 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 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.
NOTE 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 (refer to Figure 8).
Figure 8. Cable Tray Pull Tab
CAUTION (4) 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
.
CAUTION (5) If the VHDM connector has any signs of damage, DO NOT insert it into an SSR. Mark the module and slot as damaged and call TSR-BY-AVICI to request an RMA.
DO NOT insert a new router module into the slot. If the slot is damaged, only insert filler modules. Contact Support Service immediately.Step 15 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 SSR. Refer to Figure 10. If this is an Return Material Authorization (RMA), repackage according to RMA directions. Ship back to Avici.
CAUTION (6) If the empty slot is not populated with a module, it must be filled with a filler module within five minutes.
Installing Router Modules
When replacing a router module or a filler module, installation must adhere to module population rules for your type of installation (see "SSR Module Population Rules" on page 2).
Installation of the Server Attached Module (SAM) requires the re-connection of fiber optic and Ethernet cables.
CAUTION (7) 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 SAM module:
Step 1 Verify that your antistatic wrist strap is properly grounded.
Step 2 Remove the router module from its static protection bag.
Step 3 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 (refer to Figure 10).
