Table 7. Light path diagnostics
LED Problem Action
None An error has occurred and cannot
be isolated, or the service processor
has failed. The error is not
represented by a light path
diagnostic LED.
Check the system error log in the management
module for more information about the error.
DIMM x error A memory error has occurred. Replace the failing DIMM, indicated by the lit DIMM
failure LED.
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 goes away. Check the system error log in the
management module for information about the
error.
Processor x
error
The processor has failed. Make sure that the processor that is indicated by
the lit LED is installed correctly (see “Installing an
additional processor” on page 25 for installation
instructions).
Temperature
error
The system temperature has
exceeded a threshold level.
• Determine whether a blower on the SBCE unit
has failed. If it has, replace the fan.
• Make sure that the room temperature is not too
high (see “Features and specifications” on
page 4 for temperature information).
System board
error
The system board has failed. Replace the blade server cover, reinsert the blade
server in the SBCE unit, and then restart the server.
NMI error The system board has failed. 1. Replace the blade server cover, reinsert the
blade server in the SBCE unit, and then restart
the server.
2. Check the system error log in the management
module for information about the error.
Processor
mismatch
The processors do not match. Make sure that processors 1 and 2 have the same
cache size and type and the same clock speed.
Internal and external clock frequencies must be
identical.
