Light path diagnostics
Troubleshooting steps when only MEM LED lights up
Procedure
• If the server did not boot and a failing DIMM LED lights up:
1. If you have a monitor, check for a PFA log event in the system event log .
2. Reseat the DIMM.
3. If the problem still exists, move the DIMM to a different slot.
4. Look at the DIMM LEDs on the system board:
- If the DIMM LED that corresponds to the new DIMM socket lights up, replace the
DIMM.
- If the DIMM LED that corresponds to the original DIMM socket lights up, replace the
server.
• If the server booted, the failing DIMM is disabled, and the DIMM LED lights up:
1. If the LEDs light up by two DIMMs and you have a monitor, check the system event log for
a PFA event for one of the DIMMs, and then replace that DIMM. Otherwise, replace both
DIMMs
2. If the LED lights up by only one DIMM, replace that DIMM.
