This procedure uses the DIMM fault remind test circuit in the CMOD to identify the failed DIMM. The circuit is a charged, time-limited circuit. Once power is removed from the server you have 10 minutes to use the circuit.
Use this procedure to replace or reset a DIMM.
Before You Begin
For component information, see About System Components.
Use Oracle ILOM to identify the location of the failed DIMM and obtain CMOD designation information.

The Charge Status indicator [2] lights if the Fault Remind circuit is operational.
The Fault Remind circuit remains charged for about 10 minutes after power is removed from the CMOD, either by disconnecting power from the server, or by removing the CMOD from the chassis. When you press the Fault Remind button, the Charge Status indicator lights if there is enough power to use the fault remind circuit. Otherwise it remains dark.
The indicators are located next to the DIMM slots.
This action extracts the DIMM from its connector.
This action forces the DIMM into the slot and causes the two slot levers to rise and lock the DIMM in the slot.
Both levers should be in their fully closed and vertical position. In this position, the levers lock the DIMM in the slot.
When correctly seated, the cover extends slightly over the back end of the CMOD.
This action is accompanied by an audible click.
