Overview
The 1-Port OC-192c is a 10Gbit/s, single-slot module supporting PPP and Multi-Protocol Label Switching (MPLS) over SONET/SDH. Faceplate LEDs indicate module, link, and activity status (see Figure 1). The Ethernet port connection on the faceplate allows the module to serve as a Server Attached Module (SAM).
NOTE The 1-Port OC-192c is a Family 2 module. Roman numerals on the faceplate label identify the module as a Family 2 module (see Figure 1).
The 1-Port OC-192c module ships with a cable management bracket. Velcro fasteners on the cable management bracket allows for ease of dressing and organization of fiber cables. In addition, the 1-Port module ships with an Electro Magnetic Interference (EMI) dust cover installed in the port.
NOTE The cable management bracket is intended for cable management purposes only. The cable management bracket must be removed prior to removing the module.
As with all other router modules, proper installation procedure must be followed.
Figure 1. 1-Port OC-192c Module Faceplate
Optical Interfaces
This Single-Port OC-192c module supports Telcordia Single Mode Short Reach SR-1 compliant optics as described in GR-1377-CORE, compatible with SR-1 of GR-253 and I-64.1 of ITU G.691. Also supported are Single Mode Intermediate Reach interfaces compatible with Telecordia GR-253 IR-2 and ITU G.691 S-64-2b and SM LR interfaces compatible with Telecordia GR-253 LR-2 and ITU G.691 L-64.2. Refer to Table 1.
SSR Module Population Rules
Each SSR chassis has two shelves numbered from 1 (top) to 2 (bottom). Each shelf has 11 slots to house the router and route controller modules. All router modules must be inserted in pairs. Route controllers are located on the left hand side of each chassis shelf.
The location of the routing modules within the chassis creates the SSR system's "toroidal mesh." It is critical to install routing modules and route controller modules in predefined positions. All router modules must be inserted in pairs.
Figure 2. SSR Chassis Shelf and Slot Numbering
Populating the Chassis
The rules for populating the an SSR chassis with router modules is 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.
- The SSR only accepts red modules. Module color is located at the top of the module.
- The 1-Port OC-192c is a Family 2 module. Roman numerals on the faceplate identify the module as a Family 2 module (see Figure 1).
- Router modules must be added in Family pairs. That is, you must install two Family 1 modules OR two Family 2 modules.
- If installing the module in a cold chassis, follow the Population Rules outlined in the Stackable Switch Router Install Guide.
- If installing the router module in a live chassis use the show population CLI command - specifying the module family - to identify the slot(s) to populate.
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 Router Modules
Before removing or installing modules, remove the EMI front cover (if installed) as outlined in the SSR Install Guide.
Depending on the individual configuration of the SSR, either a router module or a filler module must be removed in order to install the 1-Port OC-192c module. Refer to "Removing Router Module(s)" to remove a router module. Refer to "Removing Filler Modules" to remove a filler module.
NOTE Do not insert router modules into a dedicated server module slot as this may damage the Very High Density Metric (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.
In order to prevent damage to the SSR system from static electricity, use the following precautions:
- 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.
- Handle modules by outer enclosure only. Do not touch electrical connections, pins, or soldered surfaces.
CAUTION (1) When handling modules, wear a grounded wrist strap or equivalent antistatic protection to prevent damage to electronic parts.
Installing the Antistatic Wrist Strap
A grounded antistatic wrist strap must be used to protect the SSR chassis 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

When the module is shutdown, proceed with removing the router module.
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.
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.
PROCEDURE: Use the following steps to remove the router module(s):
Step 1 Verify that your antistatic wrist strap is properly grounded.
Step 2 Undress the fiber optic cable from the cable management bracket.
Step 3 Disconnect the SC fiber optic connectors from the module (see Figure 4). Carefully undress the cable and move it to the side to avoid damage.
Figure 4. Disconnecting SC Fiber Optic Connector
Step 4 If this module is not a SAM, proceed to Step 5. If this is a SAM module, disconnect the Ethernet connector (see Figure 5). 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 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 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.
CAUTION (3) Any contact to a VHDM connector outside a SSR could damage the connector.
Step 10 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 10).
CAUTION (4) If the VHDM connector has any signs of damage, mark the module and the slot as damaged and call TSR-BY-AVICI to request an Return Material Authorization (RMA).
DO NOT insert a new router module into the slot. If the slot is damaged, only insert filler modules. Contact Support Services immediately.Figure 10. VHDM Connector
Step 11 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 (see Figure 13). If this is an RMA, repackage according to RMA directions. Ship back to Avici.
CAUTION (5) If the empty slot is not populated with a module, it must be filled with a filler module within five minutes.
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 11).
Figure 11. 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 12).

LEDs
LEDs on the faceplate of the 1-Port OC-192c module indicate the status of the module and the link and activity status of each of the ports (see Figure 21).
Board Status
The two top LEDs indicate "up" status of the board. During routing module POST, the red triangle shaped LED on the faceplate lights and remains lit until POST is completed. During Post, the green square LED blinks. After completion of POST, the green square LED remains solid and the red LED is extinguished.
The solid green LED indicates that the module has passed POST.
If the red LED remains lit, POST has detected a nonrecoverable error or fault. If the red LED remains lit, remove and reseat the module to run POST again.
Port Status
The two port LEDs indicate port status. These LEDs consist of two LEDs: the left most LED (green or not lit) indicates port status and the right most LED (amber or not lit) indicates activity status, one set per port.
When the link is up, the left most LED (L) will be solid green. If no light is present, the port is down. The right LED (A) indicates activity of the port. The right LED blinks amber when the link is actively passing traffic.
Figure 21. 1-Port OC-192c Module LEDs
Installing the Cable Management Bracket
After module installation, install the cable management bracket. Receptive screw holes in the module faceplate accept the captive screws of the cable management bracket. Velcro fasteners in the cable management bracket allow easy dressing and organization of fiber optic cables.
CAUTION (7) The cable management bracket is for cable management purposes only. The cable management bracket must be removed prior to removing the 8-Port module. DO NOT use the cable management bracket to lift or carry the 1-Port OC-192c module. Failure to adhere to these guidelines may result in equipment damage.
