■
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.

How to Isolate and Correct DIMM ECC Errors
If the ILOM reports an ECC error or a problem with a DIMM, first complete the steps in the
following procedure.
In this example, ILOM reports an error with the DIMM in CPU0, slot 1. The fault LEDs on
CPU0, slots 1 and 0, are lit.
Refer to “Using the ILOM to Monitor the Host” on page 23 for information on locating
component errors.
Caution –
Before handling components, attach an antistatic wrist strap to a chassis ground (any
unpainted metal surface). The system’s printed circuit boards and hard disk drives contain
components that are extremely sensitive to static electricity.
If you have not already done so, shut down your server to standby power mode and remove the
cover.
Refer to the Sun Fire X4640 Server Service Manual .
Inspect the CPU fault LEDs for each CPU module. The CPU fault LED will be lit on the CPU module
that has the faulty DIMM.
Disconnect the AC power cords from the server.
Remove the CPU module that has the DIMM problem.
Refer to the Sun Fire X4640 Server Service Manual .
Inspect the installed DIMMs to ensure that they comply with the DIMM Population Rules in the
Sun Fire X4640 Server Service Manual .
Press the Fault Remind button on the CPU module to light the faulty DIMM LEDs.
See “DIMM Fault LEDs” on page 15 for the location of the Fault Remind button and DIMM
fault LEDs.
