Overview
The 4-Port OC-48c is a 4-Port module supports PPP and Multi-Protocol Label Switching (MPLS) over SONET/SDH. Faceplate LEDs indicate module, link, and activity status of the module and each of the ports (see Figure 1). The Ethernet port connection on the faceplate allows the module to serve as a Server Attached Module (SAM).
NOTE The 4-Port OC-48c is a Family 2 module. Roman numerals on the faceplate label identify the module as a Family 2 module (see Figure 1).
The 4-Port OC-48c module ships with a cable management bracket. Velcro fasteners on the cable management bracket allows for easy organization of fiber cables. In addition, the module ships with an Electro Magnetic Interference (EMI) dust cover installed in each of the ports.
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. 4-Port OC-48c Module Faceplate
Optical Interfaces
This 4-Port OC-48c module supports Telcordia Single-Mode Short Reach interface compliant with SR-1 of Telcordia GR-253 and compatible with I-16 of ITU G.957, an Intermediate-Reach interface compatible with IR-2 of Telcordia GR-253, and a Long-Reach interface compliant with LR-2 of Telcordia GR -253 and ITU G.957 L-16.2. Refer to Table 1.
TSR II Module Population Rules
Each TSR II bay has four shelves numbered from 1 (top) to 4 (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 right hand side of each bay shelf.
The location of the routing modules within the bay creates the TSR II 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. TSR II Chassis Shelf and Slot Numbering
The TSR II four route controllers and numbering are shown in Figure 3.
Figure 3. Route Controller Module Numbering
Populating the Bay
The rules for populating the first TSR II Full Bay and TSR II Split Bay with router module pairs follow. See Figure 2 for TSR II bay slot number.
- 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.
- TSR II only accepts red modules. Module color is located at the top of the module.
- The 4-Port OC-48c 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 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(s) to populate.
Refer to IPriori CLI Configuration Guide (Vol. 1) and the CLI Reference 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 TSR II Install Guide.
Depending on the individual configuration of the TSR II, either a router module or a filler module must be removed in order to install the 4-Port OC-48c 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 II 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 TSR II 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 II bay shelf (see Figure 4).
Step 3 Use the ESD jack while handling modules.
Figure 4. 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#
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 route controller 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 5). Carefully undress the cable and move it to the side to avoid damage.
Figure 5. Disconnecting SC Fiber Optic Connector
Step 4 If this is SAM module, disconnect the Ethernet connector (see Figure 6). If it is not, proceed to Step 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 Very High Density Metric (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.
CAUTION (3) Any contact to a VHDM connector outside a TSR II 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 11).
CAUTION (4) If the VHDM connector has any signs of damage, DO NOT insert it into an TSR II. Mark the module and slot as damaged and call TSR-BY-AVICI to request a 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 11. 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 TSR II (see Figure 14). If this is an Request for Material Authorization (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 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 12).
Figure 12. Filler Module
If you are removing a filler module from the TSR II, use the following procedure.
PROCEDURE: Use the following steps to remove a filler module:

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 20 and Figure 21). 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 21. Router Module Installation - 6
LEDs
The 4-Port OC-48c 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 22).
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 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 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.
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 22. 4-Port OC-48c 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.
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 4-Port OC-48c module. Failure to adhere to these guidelines may result in equipment damage.

Configuring the Interfaces
Activating a 4-Port OC-48c Interfaces
PROCEDURE: Use the following steps to configure a POS interface:
Step 1 Use the show module command to display configured modules. If the 4-Port OC-48c 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 Repeat Step 1 through Step 4 for the remaining 3 interfaces on the 4 Port OC-48c module.
Step 6 Use the show interface pos bay#/slot#/port# command to display the interface:
