DIMM Fault LEDs
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.
