Table 15. EasyLED panel LEDs (continued)
LED Description
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.
SP The service processor has
failed.
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 A memory error has
occurred.
NMI A machine check error
has occurred or the NMI
button was pressed.
CNFG A hardware configuration
error has occurred.
Action
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.
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.
1. Reseat the fan.
2. Replace the failing fan, which is indicated by
a lit LED next to the fan.
1. Determine whether a fan has failed. If it has,
replace it.
2. Make sure that the room temperature is not
too high. See "Specifications" on page 10 for
the server temperature information.
3. Make sure that the air vents are not
blocked.
Replace the failing DIMM, which is indicated by
the lit DIMM latch on the system board (the
DIMM LED is underneath the DIMM latch).
Check the system-error log for information about
the error.
1. Check the microprocessors that were just
installed to make sure that they are
compatible with each other.
2. (Trained service technician only) Replace
the incompatible microprocessor.
3. Check the system-error logs for information
about the error. Replace any components
identified in the error log.
