Converting a Multichassis System Into Two Single Chassis

 

Use this procedure to convert a multichassis system into two single chassis.

Note

This procedure is service-affecting on the satellite chassis. Traffic will be affected. There is no rollback.

Caution

We recommend that you perform this procedure in a maintenance window. If this procedure is incorrectly followed, you might bring the hub chassis into a state that can only be recovered by a system repair drive.

  1. Log in to the CLI using the shared management IP address.
  2. Back up the existing configuration and save a snapshot of the state of the multichassis system.
    1. Save the configuration database to a remote location.

      For example:

      bti7800# system database backup remote-url ftp://john@10.64.7.51

      Look for the Backup successful message in the output.

    2. Save the running configuration to a remote location.

      For example:

      bti7800# show running-config | nomore | save 10.1.220.104_running_config_20150706
    3. Save the state information to a remote location.

      For example:

      bti7800# show tech-support remote-url ftp://john@10.64.7.51
  3. Disconnect the inter-chassis cables.

    You might see an alarm indicating a cable is disconnected.

  4. Remove the satellite chassis from the system.
    bti7800# show system chassis
    Caution

    If you remove the hub chassis by mistake, the hub chassis will go into a state that can only be recovered by a system repair drive.

    The hub chassis is now a single chassis system. Traffic on the hub chassis is unaffected and continues to run.

    The satellite chassis is now separate from the hub chassis. You can now turn up the satellite chassis using the initial turn-up procedures.

  5. Install and commission the satellite chassis using the procedures described in Turning Up the Software on the BTI7800 and Commissioning the BTI7800 for the First Time.

Both chassis are now single chassis systems.
