LED Problem
PS A power supply has failed.
Power supply 1 or 2 has failed.
When both the PS and CNFG LEDs are
lit, the power supply configuration is
invalid.
RAID Reserved
SP The service processor (the IMM) has
failed.
TEMP The system temperature has exceeded a
threshold level. A failing fan can cause
the TEMP LED to be lit. This condition
can also be caused by a room
temperature that is too high.
VRM Reserved.
Power-supply LEDs
About this task
The following minimum configuration is required for the DC LED on the power
supply to be lit:
v Power supply
v Power cord
The following minimum configuration is required for the server to start:
v One microprocessor (slot 1)
v One 2 GB DIMM per microprocessor on the system board (slot 3 if only one
v One power supply
v Power cord
v Three cooling fans
v One PCI riser-card assembly in PCI riser connector 2
The following illustration shows the locations of the power-supply LEDs.

microprocessor is installed)
Action
1. Check the power-supply that has an lit amber LED. (See
Table 16 on page 45 for more information.)
2. Make sure that the power supplies are seated correctly.
3. Remove one of the power supplies to isolate the failed
power supply.
4. Make sure that both power supplies installed in the server
are of the same type.
5. Replace the failed power supply.
1. Remove power from the server; then, reconnect the server
to power and restart the server.
2. Update the firmware on the IMM.
3. If the failure remains, call your next level of support.
1. Check the error log. If a fan has failed, replace it.
2. Make sure that the room temperature is not too high.
3. Once you complete the previous steps and feel the root
problem that caused a temperature issue is resolved, the
iMM interface needs to be rebooted to clear the TEMP
indicator. Follow the steps in "How to reset/reboot server
iMM interface" on page 164 and then return here.
4. If the failure remains, call your next level of support.
