Status LEDs
NMI A nonmaskable interrupt occurred. 1. If the PCI A or PCI B LED is on, follow
the instructions for those LEDs.
2. If neither the PCI A or PCI B LED is on,
restart the server.
If the problem persists, have the system
serviced.
TEMP The system temperature has exceeded a
threshold level. 1. Check to see if a fan has failed. If it has,
replace the fan.
2. Make sure the room temperature is not
too hot. (See “Features and
specifications” on page 1.)
If the problem persists, have the system
serviced.
FAN A fan has failed or is operating too slowly.
Note: A failing fan can also cause the
TEMP LED to be on.
Check the LEDs on the fan assemblies and
replace the indicated fan assembly.
MEM A memory error occurred. 1. Check the DIMM failure LEDs on the
system board.
2. Replace the DIMM indicated by the lit
DIMM failure LED.
CPU One of the microprocessors has failed or a
microprocessor is installed in the wrong
connector. 1. Check the microprocessor failure LEDs
on the system board.
2. If a microprocessor failure LED is on,
make sure the microprocessor is
installed correctly (see “Installing a
microprocessor” on page 93 ) and seated
correctly.
3. If the problem persists, replace the
microprocessor.
If the problem persists, have the system
serviced.
PCI A An error occurred on PCI bus A. An adapter
in PCI slot 1 or 2 on the system board caused
the error. 1. Check the error log for additional
information. If the error log indicates a
problem with the integrated Ethernet
controller or the integrated SCSI
controller, have your system serviced.
2. If you cannot isolate the failing adapter
from the information in the error log, try
to determine the failing adapter by
removing one adapter at a time from
PCI bus A (PCI slots 1 and 2) and
restarting the server after each adapter is
removed.
If the problem persists, have the system
serviced.
