Removing a CPU and Heat Sink

If DIMM insertion errors are detected, they may cause the blade discovery process to fail and errors will be

reported in the server POST information, which is viewable using the UCS Manager GUI or CLI. DIMMs

must be populated according to specific rules. The rules depend on the blade server model. Refer to the

documentation for a specific blade server for those rules.

Faults on the DIMMs or rear mezzanine modules also cause the server health LED to light solid amber for

minor error conditions or blinking amber for critical error conditions.
