Replace an RSM in a duplex chassis
Last Updated: June 30, 2026
  1. Wear an ESD strap when you handle the RSM module.
    Complete steps 2 and 3 only if you have made any changes to the E6000 CER configuration since the last write memory command was entered. Otherwise, skip to step 4.
  2. Execute the write memory command again.
  3. Back up the existing configuration of the RSM by performing the following steps:
    1. Enter the following command: copy running-config BKUPMMDDYY.cfg
    2. Use Secure FTP (SFTP) or FTP to transfer the backed-up configuration from the E6000 CER to another system (your PC, for example).
    The system produces the following output: Backup completed successfully.
  4. Ensure that the RSM to be replaced is in the Standby Duplex or OOS State.
    An Active RSM has all three LEDs green; a standby only has the Power and Status LEDs lit. Status can also be determined by using the show linecard status command.

    Refer to the following example output for the status of the RSM.

    show linecard status

  5. Switch sides if the desired RSM is not standby.
    After the soft-switch is made, the standby or out-of-service RSM can be replaced (you do not have to wait for it to go standby). If the desired RSM is already standby, it can be replaced immediately.
  6. Perform a soft-switch to switch the active pair over to standby: configure reset soft-switch
    NOTE: If you are using the out-of-band connection on the RPIC for access to the E6000 CER, the telnet session is disconnected during the soft-switch and you will need to telnet back in. If using an in-band connection, connectivity should not be lost.
    NOTE: We recommend that you label any cables that you disconnect so you can easily restore them to the same place.
  7. Wearing an ESD strap, perform the following:
    1. Remove any SFP modules and cables and unplug the standby RSM card.
    2. Plug in the replacement RSM.
    3. Install the front SFP modules installed in the new RSM and connect the cables.
  8. Allow the E6000 CER to return to duplex mode and confirm this by executing the show linecard status command.
    The standby RSM will display IS Standby.
  9. Do a reload commit.
  10. Check system for normal operation.
