LED Description Action
Configu
Microprocessor
A hardware configuration error
has occurred.
If the Configuration LED and the Microprocessor LED are
lit, complete the following steps to correct the problem:
1. Check the microprocessors that were just installed
to make sure that they are compatible with each
other (see “Installing a microprocessor and heat
sink” on page 276 for additional information about
microprocessor requirements).
2. (Trained technician only) Replace the incompatible
microprocessor.
3. Check the system-event logs for information about
the error (see “Event logs” on page 139). Replace
any component that is identified in the error log.
Configu Memory
A hardware configuration error
has occurred.
If the Configuration LED and the Memory LED are lit,
check the system-event logs for information about the
error (see “Event logs” on page 139).
Configuration
Configu Power supply
A hardware configuration error
has occurred.
If the Configuration LED and the Power supply LED are
lit, the system issues an invalid power configuration error.
Make sure that both power supplies installed in the server
are of the same rating or wattage.
When only the Memory LED
is lit, a memory error has
occurred. 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.
If the Configuration LED is not lit, the system might detect
a memory error. Complete the following steps to correct
the problem:
1. Reseat or swap the DIMMs with lit LEDs.
2. Check the system-event logs for information about
the error (see “Event logs” on page 139).
3. Update the server firmware to the latest level (see
“Updating the firmware” on page 103 for more
information).
4. Replace the failing DIMM (see “Installing a DIMM”
on page 257).
Memory
Configuration
When both the Memory and
Configuration LEDs are lit,
the memory configuration is
invalid.
If the Memory LED and the Configuration LED are lit,
check the system-event logs for information about the
error (see “Event logs” on page 139).
