Overview

The 16-Port OC-3c router module provides support for 16 multiple interfaces. This router module supports PPP, POS, IS-IS, OSPF, BGP, MBGP, LDP, PIM (sparse mode), RSVP, and MPLS protocols.

NOTE To visually identify the 16 Port OC-3c single-mode router module, product ID numbers are located on the faceplate label. M16-S103-[IR|SR|LR]-R refers to the single mode red module and M16-S103-MM-R refers to the multimode red module.

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 two shelves and their slots are illustrated in Figure 1.

Removing a 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.

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 3 and Figure 4).

Figure 3. Router Module Faceplate

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.

Step 2 Disconnect the lower fiber optic cables from the fiber cable adapters (SC/QC) 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 4).

Figure 4. 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.

Installing Router Module Fiber Optic Cables

The 16-Port OC-3c router module provides support for 16 multiple interfaces over Point-to-Point Protocol (PPP) and Packet Over Sonet (POS). Each router module has three cable trays. The cable tray labeled "AUX" is used when the module is used as a server attached module (SAM). There are two fiber optic cable trays, each cable tray containing four simplex fiber cable connectors (16 total). Each simplex fiber cable connector provides 2 ports. Refer to Figure 23 for port numbering on the center cable tray. Refer to Figure 24 for port numbering on the right hand cable tray. Figure 29 "Ports 1-8 Optical Cabling Schematic and Figure 30 "Ports 9-16 Optical Cabling Schematic" outlines the schematic of each optical port in the 16-Port module.

Cleaning the Fiber Optic Connections

The 16-Port OC-3c uses single mode or multi mode fiber optic cable. Every time a fiber optic cable is attached or re-attached, the fiber cable must be cleaned using a special fiber optic cleaner. In addition, the fiber cable adapter (SC/QC) must also be cleaned each time a fiber is installed.

CAUTION (8) When handling circuit cards (such as those enclosed in the router module), wear a grounded wrist strap or equivalent antistatic protection to prevent damage to electronic parts (refer to "Installing the Antistatic Wrist Strap").

The following cleaning supplies are needed to clean the fiber optic cable before installing it in the router module:

CAUTION (9) Fiber optic cables must be thoroughly cleaned each time a cable is connected or reconnected. Failure to do so may impact performance or damage to the fiber optic cable.

PROCEDURE: Use the following procedure to clean the ferrule of the SC/QC connectors being installed:

Step 1 Using a lint-free tissue soaked with isopropyl alcohol, wipe around the ferrule of the SC/QC connector (refer to Figure 21).

Step 2 Gently wipe across the end face of the connector (refer to Figure 21).

Step 3 Repeat Step 1 and Step 2 using a dry lint-free tissue.

Figure 21. Cleaning the SC/QC Connector

Step 4 Using a lint-free tab soaked with isopropyl alcohol to wipe the connector's both sides of the guide grooves. Alignment of the SC/QC mechanism is based on ferrule's side guide grooves. It is critical to keep them clean. (refer to Figure 22).

Figure 22. Cleaning SC/QC Guide Grooves

Step 5 Complete the cleaning by using the filtered compressed air on the aerosol duster (dust-free) to blow the end faces of the SC/QC connector.

NOTE If using an aerosol duster, keep the nozzle at least 2 in. (5 cm) away from the connector.

Step 6 Make a visual inspection of the connector end face with the microscope. Repeat Step 1 through Step 5 if necessary.

Step 7 Use the aerosol duster (dust-free) to blow air inside the SC/QC adapter.

Step 8 If the connector is satisfactory, immediately mate it in the appropriate adapter or sleeve.

Installing Fiber Optic Cables

PROCEDURE: Use the following procedure to install fiber optic cables:

Step 1 Feed each (2 sm) fiber cable up through the bottom or down from the top of the bay and into the vertical cable channel.

Step 2 Feed the cable(s) from the vertical cable channel to the horizontal cable channel nearest the router module.

Step 3 Feed the fiber cable(s) from the horizontal cable channel up to the vertical cable management tray.

Step 4 Gently slide out the center cable management tray marked "1-8." Refer to Figure 23 for tray and label numbering and Figure 24 for laser warning label).

Step 1 Use the show module command to display configured modules. If the 16-port OC-3c 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.

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 awar 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 15 interfaces on the 16 Port OC-3c module.

Step 6 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
