In the Sun Fire X4640 servers, eight DIMM slots are on each removable CPU module. The DIMM fault LEDs in the DIMM slot ejector levers indicate which DIMM pair has failed. These DIMM fault LEDs can be lit for up to one minute by a capacitor on the CPU module, even after the CPU module is removed from the server.

The CPU fault LED indicates which CPU module contains the faulty DIMM.
To light the fault LED from the capacitor, push the small button on the CPU module labelled “FAULT REMIND BUTTON.”
The DIMM ejector levers contain LEDs that can indicate a faulty DIMM.
DIMM fault LED is off– The DIMM is operating properly.
DIMM fault LED is on (amber)– At least one of the DIMMs in this DIMM pair is faulty and should be replaced.
