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 diagnostics 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, which is 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 the error
is corrected. Check the system error log in the
management module for information about the error.
If the problem remains, have the blade server
serviced.
SAS hard disk
drive-LED
Reserved Reserved
Processor x error The microprocessor has failed. Make sure that the microprocessor that is indicated by
the lit LED is installed correctly (see “Installing an
additional microprocessor” on page 28 for installation
instructions).
If the problem remains, have the blade server
serviced.
Temperature error
(TEMP)
The system temperature has exceeded
a threshold level.
v Determine whether a blower on the BladeCenter
unit has failed. If it has, replace the blower.
v Make sure that the room temperature is not too high
(see “Features and specifications” on page 7 for
temperature information).
If the problem remains, have the blade server
serviced.
System board error
(S BRD)
The system board has failed 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.
NMI error The system board has failed.
v Replace the blade server cover, reinsert the blade
server in the BladeCenter unit, and then restart the
server.
v Check the system error log in the management
module for information about the error.
If the problem remains, have the blade server
serviced.
Processor
mismatch (MIS)
The processors do not match. Make sure that microprocessors 1 and 2 have the
same cache size and type and the same clock speed.
Internal and external clock frequencies must be
identical.
If the problem remains, have the blade server
serviced.
