Remove an External 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.

  4. Locate the external interconnect assembly at the front of the server.

    See CMIOU Chassis Front Components and Switch Chassis Front Components (SPARC M7-16).

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

    If you are removing one or more external 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 or SPPs, and unseat the SP tray from the impacted chassis.

    Servicing SPs and Servicing SP Trays.

  7. Unseat all CMIOUs and switch units from the impacted chassis.

    See Servicing CMIOUs and Servicing Switch Units.

  8. Use a T20 driver to remove the four screws that secure the interconnect cable cover to the chassis, and remove the cover.

  9. From the front of the server, remove the external interconnect assembly.


    Caution  -  The small connector pins on the back of the assembly are susceptible to damage. Remove the assembly slowly to avoid bending or otherwise damaging them. In addition, take care to avoid flexing or twisting these assemblies.

    1. Loosen the captive screws on the assembly.

      When the spring-loaded screw springs out, press on the upper screw at each end of the external interconnect to unlatch the assembly from the chassis.

    2. Grasp the assembly and slide it out of the chassis using either the screw or center finger holds.
