If the DIMM Fault LED is on (amber), then the DIMM is faulty and should be replaced [4].
■
To locate the failed DIMM, press and hold the Fault Remind button [1].
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 for troubleshooting.

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 unlit.
