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.
TSR 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 server modules (see Figure 2). All router modules must be inserted in pairs.
Bay Numbering
Bay numbering for the TSR is as follows: all bays will be numbered odd in the first row; for example: 1, 3, 5, and even in the second row; for example: 2, 4, 6. This numbering system is more logical for a larger scale system typically found in a POP (with odd first row and even second row.) Refer to Figure 1.
Figure 1. TSR Bay Numbering
The four shelves and the router module numbering is as follows:
Figure 2. TSR Bay Shelf and Slot Numbering
Populating First 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.
The rules for populating the first TSR Full Bay and TSR Split Bay with router module pairs follow.
- The server modules are restricted to slots 11 and 31 in Full Bay configurations. In the Split Bay configuration, server modules are restricted to slots 11 and 20 for the upper router and in slots 31 and 40 of the lower router.
- When only one server is installed, install it slot 11.
- Modules occupying a slot use the slot number as its identifier. 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.
- The 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.
- 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 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. I) for further information on this command. Online versions of the manuals are available at http://www.avici.com/documentation.
Preparing to Install Router Modules
Use these precautions to prevent damage from static electricity during removal and installation of router modules:
- 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.
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. In TSR bays, there are two ESD jacks locations (see Figure 3).
PROCEDURE: Use the following procedure to install the antistatic wrist strap in the TSR bay:
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 rear of the TSR (refer to Figure 3).
Step 3 Use the ESD jack while handling modules.
Figure 3. TSR - ESD Jack Locations
Removing Router Module(s)
Depending on the individual configuration of the TSR, either a router module or a filler module must be removed in order to install throatier module. Refer to "Removing Router Module(s)" to remove a router module. Refer to "Removing Filler Modules" to remove a filler module.
Before removing a router 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.
CAUTION (1) When handling modules, wear a grounded wrist strap or equivalent antistatic protection to prevent damage to electronic parts.
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.

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.
When the module is shutdown, proceed with removing the router module.
Prior to removing a module you must shut down the module being replaced.
PROCEDURE: Use the following steps to remove the router module(s):
Step 1 Open the pull tab on the center cable tray and gently pull the center cable tray out of the router. Refer to and Figure 4 and Figure 5.
WARNING 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 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.

LEDs
Each module has one green square LED and one red triangle LED visible on the module faceplate (refer to Figure 23).
Figure 23. Routing Module LEDs
During routing module POST, the red LED on the faceplate lights until POST is completed. After completion of POST, the green LED lights and the red LED is extinguished.
The solid green LED indicates that the module has passed POST.
Step 1 If the red LED remains lit, POST has detected a nonrecoverable error or fault. If the red LED remains lit, remove
Configuring the Interfaces
To configure the router module, activate the installed module and configure the interface as described in the following sections.
Activating a POS Interface
PROCEDURE: Use the following steps to configure a POS interface:
Step 1 Use the show module command to display configured modules. If the router module is shut down, use the no shutdown command in module configuration mode to activate the module.
Step 2 Use the configure terminal command to enter configuration command mode.
Step 3 Use the interface command pos bay/slot/port location to enter interface configuration command mode.
Step 4 Optionally, modify the default settings.
Step 5 Optionally, configure a description for the interface using the description command.
Step 6 Configure the local address using the ip address command.
Step 7 Use the no shutdown command to activate the interface.
Step 8 Use the show interface command to display and verify the new interface configuration.
The interface Command
The interface command defines/deletes an interface.
Syntax: [no] interface pos bay/slot/port
pos
Configures the interface to support pos.
bay/slot/port
Identifies a specific interface on the TSR. Valid values are as follows:
bay: Bay number. Valid values 1 - 2. Default 1.
slot: Slot number where the module is installed in the TSR. Valid values are integers between 1 and 40.port: Valid values are 1 - 2.
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.
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 1/35/1
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
