Remove an Internal Interconnect Assembly

This procedure can be performed only by qualified service personnel. Remove AC power using the circuit breakers on the appropriate PDU before performing this procedure.

1. Determine which interconnect 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.

   See Removing Power From the Server or Domain.

   See CMIOU Chassis Front Components.

5. (Important) Label the internal interconnect assembly slots and assemblies.

   If you are removing one or more internal interconnect assemblies and will return them to the server (for example, because you are removing them to gain access to other components), you must return them to their original locations in the server. Take care to properly label each slot and assembly to ensure that it is properly reinstalled.

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