Caution

Caution  -  Remove AC power using the circuit breakers on the appropriate PDU before performing this procedure.


  1. Determine which front indicator panel cable requires service.

    See Identify Faulted Components.

  2. Take the necessary ESD precautions.

    See Prevent ESD Damage.

  3. Power off the server and switch off the appropriate PDU circuit breakers.

  4. From the rear of the server, remove the SPs, and unseat the SP tray from the impacted chassis.

    See Servicing SPs and Servicing SP Trays.

  5. Remove and unseat the appropriate components from the impacted chassis.
    • If the cable you are replacing is in the CMIOU chassis, remove the top four CMIOUs and unseat the lower four CMIOUs in the chassis. See Servicing CMIOUs.

    • If the cable you are replacing is in the switch chassis, remove the top three switch units and unseat the lower three switch units in the chassis. See Servicing Switch Units.

  6. Remove the required fan modules.

    If the cable you are replacing is in the CMIOU chassis, remove the four left fan modules. See Servicing Fan Modules (CMIOU Chassis).

  7. Remove of the interconnect assemblies from the front of the affected chassis.
