Table 2. EasyLED diagnostics (continued)
v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v See the parts listing in the Hardware Maintenance Manual to determine which components are customer
replaceable units (CRU) and which components are field replaceable units (FRU).
v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
LED Description Action
PCI An error has occurred on a PCI
bus or on the system board. An
additional LED will be lit next to a
failing PCI slot.
1. Check the LEDs on the PCI slots to identify the
component that caused the error.
2. Check the system-error log for information about the error.
3. If you cannot isolate the failing adapter using the LEDs
and the information in the system-error log, remove one
adapter at a time from the failing PCI bus; then, restart the
server after each adapter is removed.
4. If the problem remains, replace the following components,
in the order shown, restarting the server each time:
v PCI riser card
v (Trained service technician only) Replace the system
board, if the problem remains.
SP The service processor has failed.
1. Remove power from the server; then, reconnect the server
to power and restart the server.
2. Update the IMM firmware.
3. (Trained service technician only) Replace the system
board, if the problem remains.
FAN A fan has failed, is operating too
slowly, or has been removed. The
TEMP LED might also be lit.
1. Reseat the fan.
2. Replace the failing fan, which is indicated by a lit LED
next to the fan.
TEMP The system temperature has
exceeded a threshold level. A
failing fan can cause the TEMP
LED to be lit.
1. Determine whether a fan has failed. If it has, replace it.
2. Make sure that the room temperature is not too high. See
Table 1 on page 11 for the server temperature information.
3. Make sure that the air vents are not blocked.
MEM An invalid memory configuration
or a memory error has occurred
(both the MEM LED and the
CNFG LED might be lit).
1. If the MEM LED and the CNFG LED are lit, the system
issues an invalid memory configuration error. Complete
the following steps to correct the problem:
a. Make sure that the DIMM configuration is supported.
b. Replace the DIMMs with a supported configuration.
2.
If the CNFG LED is not lit, the system might detect a
memory error. Complete the following steps to correct the
problem:
a. Run the memory test to isolate the problem.
b. If the test indicates that a memory error has occurred,
replace the failing DIMM, which is indicated by the lit
DIMM latch on the system board (the DIMM LED is
underneath the DIMM latch).
NMI A machine check error has
occurred or the NMI button was
pressed.
Check the system-error log for information about the error.
