Overview
The MSC module supports Asynchronous Transfer Mode (ATM) services. At present, there are three variations of the MSC module:
- 8-Port OC-12/STM-4
- 16-Port OC-3/STM-1
- 8-Port OC-3/STM-1|4-Port OC-12/STM-4
Labels on the MSC module faceplate identify the module type, the interface type, and the family type (see Figure 1). In addition, labels on each MSC modules indicate port numbering (see Figure 2).
In addition, faceplate LEDs indicate module, link, and activity status of the module and each of the ports. The Ethernet port connection on the faceplate allows the module to serve as a Server Attached Module (SAM).
NOTE The 8-Port OC-12, the 16-Port OC-3, and the 8-Port OC-3/4-Port OC-12 MSC modules are all Family 2 modules. Roman numerals on the faceplate label identify the module as a Family 2 module (see Figure 1).
Router modules must be installed in family pairs.That is, you must install two Family 1 or two Family 2 modules.All MSC modules ship with a cable management bracket with Velcro fasteners on the cable management bracket for easy organization of fiber cables. In addition, the module ships with dust covers installed in each of the ports.
For instructional purposes, only images of the 8-Port OC-12 MSC module are used throughout this document to demonstrate the installation procedures for MSC modules types.
NOTE The cable management bracket is for cable management purposes only. You must remove the cable management prior to removing the module.
As with all other router modules, proper installation procedure must be followed.
Figure 1. MSC Module Type Labels
Figure 2. MSC Module Port Numbering Labels
Optical Interfaces
All MSC modules support either Single Mode Intermediate Reach Telecordia GR-253 IR-1 compatible with S4.1 of ITU G.957 or multimode interfaces. Refer to Table 1.
TSR II Module Population Rules
Each TSR bay has four shelves numbered from 1 (top) to 4 (bottom). Each shelf has 10 slots to house the router and route controller modules (see Figure 3). All router modules must be inserted in family pairs.
The location of the routing modules within the bay creates the TSR system's "toroidal mesh." It is critical to install routing modules and route controller modules in predefined positions. Install router modules in family pairs.
Figure 3. TSR Bay Shelf and Slot Numbering
Populating the Bay
The rules for populating the first TSR Full Bay and TSR Split Bay with router module pairs follow. See Figure 3 for TSR bay slot number.
- Modules occupying a slot use the slot number as its identifier. In a multibay system, a module is identified by bay number/slot number; i.e., 1/10 would be bay 1, slot 10.
- Slots with red circles only accept modules with red circles. Slots with blue squares only accept modules with blue squares. Module color and shape identifiers are on the top of the modules and on the top and bottom of each shelf slot (see Figure 4 and Figure 5).
Figure 4. TSR Red (Circle) Module Identification
Figure 5. TSR Blue (Square) Module Identification
- The MSC module is a Family 2 module. Roman numerals on the faceplate label 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 bay, follow the Population Rules outlined in the Terabit Switch Router 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(s) to populate. Module color is represented in the CLI as R for red and B for blue.
Refer to IPriori CLI Reference and Configuration Guides (Vol. 1) for further information on this command. Online versions of all 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 TSR Install Guide.
Depending on the individual configuration of the TSR, either a router module or a filler module must be removed in order to install the MSC 8-Port OC-12c module. Refer to "Removing Router Module(s)" to remove a router module. Refer to "Removing Filler Modules" to remove a filler module.
In order to prevent damage to the TSR 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 properly grounded 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 TSR bay 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 (see Figure 6).
Step 3 Use the ESD wrist strap while handling modules.
Figure 6. ESD Jack Locations
Removing Router Module(s)
Before removing a module you must shut down the module being replaced. Use the shutdown command to disable all functions on the module. The module appears as administratively down when executing the show mod brief command.
Shutting Down the 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.
Example: Use the shutdown command to disable all functions on the module. The module appears as administratively down when executing the show mod brief command.
router(config)#module 1/25/1
router(config)#shutdown
This command will disable module 1/25.
Are you sure [yes|no}? yes

router#
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.
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.
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 LC fiber optic connectors from the module (see Figure 7). Carefully undress the cable and move it to the side to avoid damage.
Step 4 Replace dust caps into each of the module ports after disconnecting fiber optic connectors.
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.
Replace dust caps into module ports after disconnecting fiber optic connectors.Figure 7. Disconnecting LC Fiber Optic Connector
Step 5 If this is SAM module, disconnect the Ethernet connector (see Figure 8). If it is not, proceed to Step 6. Hang the Ethernet cable down and out of the way, or tuck the cable into the horizontal cable tray under the module shelf.
Figure 8. Disconnecting Ethernet Connector
Step 6 Using the 3/8 in flat-head screwdriver, unscrew the captive screws in the cable management bracket and remove the bracket from the module (see Figure 9).
Figure 9. Cable Management Bracket Removal
Step 7 Release the module from the backplane, simultaneously rotate the ejector latches to a fully open position and carefully pull the router a few inches out of the shelf (see Figure 10 and Figure 11).
Figure 10. Router Module Removal - 1
Step 8 To remove the module, grasp it on the top and bottom and pull it carefully out of the shelf.
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 9 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 (see Figure 12).
Figure 12. Router Module Removal - 3
Step 10 To remove the module, grasp it on the top and bottom and pull it carefully out of the shelf.
CAUTION (4) 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.
Any contact to a VHDM connector outside a TSR could damage the connector.Step 11 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).
CAUTION (5) If the VHDM connector has any signs of damage, DO NOT insert it into an TSR. Mark the module and 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 Service immediately.Figure 13. VHDM Connector
.
Step 12 Before placing the module in a static-proof bag, replace the VHDM (Very High Density Metric) 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 (see Figure 14).
CAUTION (6) If the empty slot is not populated with a module, it must be filled with a filler module within five minutes.
Step 13 If this is an RMA, repackage according to RMA directions. Ship back to Avici.
Figure 14. Replacing the VHDM Protective Cap
CAUTION (7) 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 TSR 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 15).
Figure 15. Filler Module
If you are removing a filler module from the TSR, 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 16).
Step 3 Store the filler module in a dry, cool area.

Figure 23. Router Module Insertion - 5
Step 11 Simultaneously depress the release levers on the top and bottom ejector latches and rotate the ejector latch to the closed position (see Figure 23 and Figure 24). Release the release levers once the ejector latches are closed.
NOTE If the ejector latches will not close, reseat the module by pulling it six inches out of the slot and then repeating Step 7 through Step 11, making sure the module is not inserted too far into the slot. If the ejector latches still do not close after reseating the module, contact Avici Customer Support.
Figure 24. Router Module Insertion - 6
LEDs
The MSC module supports LEDs on the faceplate to indicate the status of the module and the link and activity status of each of the ports (see Figure 25).
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. After completion of POST, the green square LED lights and blinks and the red LED is extinguished. The green LED remains in the blinking state until the module is enabled, at which time the LED transitions to solid.
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 eight (two per port) bottom bi-color LEDs, indicate port status. These bottom LEDs consist of two pairs of 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.
The right LED (A) indicates activity of the port. The right LED blinks amber when the link is actively passing traffic.
Figure 25. MSC Module LEDs
Installing the Cable Management Bracket
After installing the module, 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.
NOTE The cable management bracket is intended for cable management purposes only. The cable management bracket must be removed prior to removing the module.
Figure 26. Cable Management Bracket Installation
PROCEDURE: Use the following procedure to install the cable management bracket to the module:
Step 1 Remove the cable management bracket from its package.
Step 2 Position the cable management bracket as shown in Figure 26.
Step 3 Using a 3/8 in flat-head screwdriver, attach the bracket to the module faceplate by tightening the captive screws (see Figure 26).
CAUTION (10) 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 MSC module. Failure to adhere to these guidelines may result in equipment damage.
Installing Fiber Optic Cables
The installation of fiber optic cables in the MSC module follows the usual procedure for fiber optic installation. If connecting all 4 ports, remove the dust cap and install the fiber optic cables in one port at a time. Dust caps should only be removed immediately prior to fiber optic cable installation. Clean all fiber optic connectors according to manufacturer's instructions.
CAUTION (11) Fiber optic cables must be thoroughly cleaned each time a cable is connected or reconnected. Failure to do so may impact performance to the fiber optic cable.
PROCEDURE: Use the following steps to install the fiber optic cables in the MSC module:
Step 1 Verify that your antistatic wrist strap is properly grounded.
WARNING (2) 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 27. Removal of Dust Cap
Step 2 Remove cap from fiber optic cable connector and insert LC connector into the port slot (see Figure 27 and Figure 28).
Figure 28. Installation of Fiber Optic Connector/Cable
NOTE If installing fiber optic cables into all 8 ports at once, begin at the bottom port (No. 8) and move upward to for ease of fiber management.
Step 3 Repeat Step 2 for each fiber optic connection.
Step 4 Use the Velcro fasteners on the cable management bracket to dress the fiber optic cables (see Figure 29).
