LED Description Action
MEM When only the MEM LED is lit, a
memory error has occurred.
When both the MEM and CNFG
LEDs are lit, the memory
configuration is invalid or the PCI
Option ROM is out of resource.
1. If the MEM LED and the CNFG LED are lit, complete the
following step:
a. Check the system-event log in the Setup utility or IMM
error messages (see the Problem Determination and
Service Guide for more information).
2. If the CNFG LED is not lit, the system might detect a
memory error. Complete the following steps to correct the
problem:
a. Update the server firmware to the latest level (see the
Problem Determination and Service Guide for more
information).
b. Reseat or swap the DIMMs.
c. Check the system-event log in the Setup utility or IMM
error messages (see the Problem Determination and
Service Guide for more information).
NMI A nonmaskable interrupt has
occurred, or the NMI button was
pressed. Check the system-error log for information about the error.
CNFG A hardware configuration error
has occurred.
1. If the CNFG LED and the CPU LED are lit, complete the
following steps to correct the problem:
a. Check the microprocessors that were just installed to
make sure that they are compatible with each other
(see “Installing a second microprocessor and heat
sink” on page 84 for additional information about
microprocessor requirements).
b. (Trained service technician only) Replace the
incompatible microprocessor.
c. Check the system-error logs for information about the
error. Replace any components that are identified in
the error log.
2. If the CNFG LED and the MEM LED are lit, complete the
following step:
a. Check the system-event log in the Setup utility or IMM
error messages (see the Problem Determination and
Service Guide for more information).
