Table 2. Light path diagnostics Lit blade-error LED Cause None An error has occurred and cannot be isolated, or the service processor has failed. DIMM x error A memory error occurred. Action An error has occurred that is not represented by a light path diagnostics LED. Check the system event log in the BladeCenter management module for more information about the error. Replace the DIMM indicated by the lit DIMM failure LED. 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 error is corrected. Check the system event log in the BladeCenter management module for information about the error. Processor x error The microprocessor has failed. Service processor The service processor has failed. error NMI error The system board has failed. If the problem remains, have the blade server serviced. Attention: To help ensure proper cooling and system reliability, two microprocessors and two heat sinks are required on the system board in the blade server at all times. The microprocessors and heat sinks on the system board are not replaceable. Therefore, if a microprocessor or heat sink becomes defective, you must replace the system-board assembly. Contact a service support representative for assistance. Have the blade server serviced. Note: There are two service processor error LEDs: CR27 (amber) and CR38 (green). 1. Replace the blade server cover, reinsert the blade server in the BladeCenter unit, and then restart the server. 2. Check the system event log in the BladeCenter management module for information about the error. System board error The system board has failed. If the problem remains, have the blade server serviced. Replace the blade server cover, reinsert the blade server in the BladeCenter unit, and then restart the server. If the problem remains, have the blade server serviced. 82 BladeCenter JS20 Type 8842: Installation and User's Guide

LED
Cause
Action
None
An
error
has
occurred
and
cannot
be
isolated,
or
the
service
processor
has
failed.
An
error
has
occurred
that
is
not
represented
by
a
light

diagnostics
LED.
Check
the
system
event
log
in
the
BladeCenter
management
module
for
more
information
about
the
error.
DIMM
x
error
A
memory
error
occurred.
Replace
the
DIMM
indicated
by
the
lit
DIMM
failure
LED.
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
error
is
corrected.
Check
the

CR27
(amber)
and
CR38
(green).
NMI
