None
Battery error
DIMM x error
Light path diagnostics LED
Description
An error has occurred and
cannot be isolated, or the
IMM2 has failed.
The battery failed.
A memory error occurred.
System board light path
diagnostics LEDs have
power.
Action
Make sure that the light path
diagnostics LED is lit to
ensure that there is enough
power in the compute node
to light the rest of the LEDs.
1. Reseat the battery.
2. Replace the battery.
3. (Trained service
technician only) Replace
the system-board
assembly.
1. Make sure that the
DIMM that is indicated
by the lit LED is
supported.
2. Reseat the DIMM that is
indicated by the lit LED.
3. Replace the DIMM that is
indicated by the lit LED
(see "Removing a DIMM"
on page 501, and
"Installing a DIMM" on
page 502)
Note: Multiple DIMM LEDs
do not necessarily indicate
multiple DIMM failures. If
more than one DIMM LED is
lit, reseat or replace one
DIMM at a time until the
error is corrected (see
"Removing a DIMM" on
page 501, and "Installing a
DIMM" on page 502)
Check for error LEDs that
are lit on the system board
assembly.
