Converting and Connecting the Control Planes Between an Operational T640 Router and the TX Matrix Router

 Note

We recommend that you manage the system using a directly attached management device instead of an out-of-band management device. An attached management device provides you access to the system if the control plane is not functioning.

The connections between the TX-CIPs in the TX Matrix Router SFC and the Control Boards in the LCC are proprietary Ethernet connections. Do not attempt to connect these components through a switch or hub.

To convert and connect the control planes of an operational T640 router:

  1. Determine which host subsystem is functioning as the master or the backup by using one of the two following methods:
    • Check the Routing Engine LEDs on the craft interface. If the green MASTER LED is lit, the corresponding host subsystem is functioning as the master.

    • Issue the following CLI command. The master Routing Engine is designated Master in the Current state field:

      user@host> show chassis routing-engine
  2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  3. Set the switches on each Control Board before you install them in the T640 LCC:
    • Set the chassis ID switch on each Control Board to 0.

    • Set the M/S switch on each Control Board faceplate to S.

    Note

    When you integrate an operational T640 router with the TX Matrix router, you must assign a chassis ID of 0 to the router.

  4. Replace the backup CB with a T-CB or LCC-CB. Use the standard replacement procedures described in the T640 Core Router Hardware Guide.
  5. Perform a graceful switchover to the backup by issuing the request chassis routing-engine master switch command:
    user@host> request chassis routing-engine master switch

    For more information, see Configuring Graceful Routing Engine Switchover and request chassis routing-engine master.

  6. Replace the other Control Board (which now belongs to the backup host subsystem) with a T-CB or LCC-CB. Use the standard replacement procedures described in the T640 Core Router Hardware Guide.
  7. Perform a graceful switchover to the original master by issuing the request chassis routing-engine master switch command:
    user@host> request chassis routing-engine master switch
  8. Verify that the T-CBs or LCC-CBs are displayed in the output of the show chassis hardware command.

    This example show the LCC-CB (model number CB-LCC).

    user@host> show chassis hardware

    This example show the T-CB (model number CB-T) shown as T-Series Control Board in the CLI output.

    Note

    The T640 control board (model number CB-L-T), shown as CB-T in CLI output, is not supported for T640 LCCs.

    user@host> show chassis hardware
  9. Plug one end of a UTP Category 5 cable into the appropriate RJ-45 port on the TX-CIP in slot CIP0. See Table 1.
  10. Plug the other end of the cable into the appropriate port in the T640 LCC Control Board in slot CB0. Dress the cable appropriately.
    • T-CB installed in slot CB0CIP port

    • LCC-CB installed in slot CB0TX port

  11. Plug one end of a UTP Category 5 cable into the appropriate RJ-45 port on the TX-CIP in slot CIP1.
  12. Plug the other end of the cable into the appropriate port in the T640 LCC Control Board in slot CB1. Dress the cable appropriately.
    • T-CB installed in slot CB1CIP port

    • LCC-CB installed in slot CB1TX port

  13. Verify the Ethernet connection LEDs.
    • TX-CIP LCC 0, LCC 1, LCC 2, or LCC 2 ,port

    • T-CB CIP port is lit green, which indicates a 100-Mbps connection.

    • LCC-CB TX port is lit green, which indicates a 100-Mbps connection.
