In Oracle's SPARC M7-16 server, eight external interconnect assemblies connect the CMIOUs in the top chassis and the CMIOUs in the bottom chassis to the switch units in the switch chassis. One half of an assembly is installed in the switch chassis, and the other half of the assembly is installed in a CMIOU chassis.
For the location of the external interconnect assemblies, see Switch Chassis Front Components (SPARC M7-16).
Caution - This procedure requires that you handle components that are sensitive to electrostatic discharge. This discharge can cause server components to fail. Follow antistatic precautions to prevent electrostatic damage. See Prevent ESD Damage.
These topics explain how to service external interconnect assemblies.
