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 serviceability, locations, and designations, see About System Components.
Use Oracle ILOM to identify the location of the failed DIMM and obtain CMOD designation information.
For servers equipped with SW 1.0 and with versions of Oracle ILOM older than 126.96.36.199, use cold service. See Prepare the Server for Cold Service.
For servers equipped with SW 1.1 and with Oracle ILOM 188.8.131.52 or newer, use cold service or warm service. For warm service, see Prepare the Server for Warm Service.
Caution - Component damage. CMOD components are extremely sensitive to electrostatic discharge. Wear a wrist strap and use an anti-static wrist mat.
The green LED lights to indicate that the circuit is operational.
The indicators are located next to the DIMM slot.
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.
