v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v If a action step is preceded by "(Trained technician only)," that step must be performed only by a trained
technician.
LED Description
PCI An error has occurred on a PCI
card, a PCI bus or on the system
board. An additional LED is lit
on one of the riser cards.
FAN A fan has failed, is operating too
slowly, or has been removed. The
TEMP LED might also be lit.
TEMP The system temperature has
exceeded a threshold level. A
failing fan can cause the TEMP
LED to be lit.
MEM An invalid memory configuration
(both the MEM LED and
CONFIG LED might be lit) or a
memory error has occurred .
NMI A nonmaskable interrupt has
occurred, or the NMI button was
pressed.

Action
1. Check the system-event log for information about the
error.
2. Check the LEDs on the PCI riser cards to identify the
component that caused the error.
3. If you cannot isolate the failing adapter by using the
LEDs and the information in the system-event log,
remove one adapter at a time from the failing PCI bus;
and restart the server after each adapter is removed.
4. Replace the following components, in the order shown,
restarting the server each time:
v PCI riser card
v (Trained technician only) Replace the system board.
1. Check the LEDs on the server.
2. Reseat the failing fan, which is indicated by a lit LED on
the fan.
3. Replace the failing fan.
1. Make sure that the air vents are not blocked.
2. Determine whether a fan has failed. If it has, replace it.
3. Make sure that the heat sink is seated correctly.
4. Make sure that the room temperature is not too high. See
"Server features and specifications" on page 6 and
"System reliability guidelines" on page 32 for the server
temperature information.
Note: Each time you install or remove a DIMM, you must
disconnect the server from the power source; then, wait 10
seconds before restarting the server.
1. If the MEM LED and the CONFIG LED are lit, the system
issues an invalid memory configuration error. Complete
the following steps to correct the problem:
a. Check the system-event log in the Setup utility or
IMM error messages. Follow steps indicated in "POST
error codes" on page 122 and Integrated management
module II (IMM2) error messages.
2. If the CONFIG LED is not lit, the system has detected a
memory error. Complete the following steps to correct the
problem:
a. Update the firmware to the latest level (see "Updating
the firmware" on page 71).
b. Reseat or swap the DIMMs.
c. Check the system-event log in the Setup utility or
IMM error messages. Follow steps indicated in "POST
error codes" on page 122 and Integrated management
module II (IMM2) error messages.
Check the system-event log for information about the error.
