Table 7. I/O board light path diagnostics LEDs (continued)
LED Problem Action
Temperature error The system temperature has
exceeded a threshold level.
v Check to see whether a blower on the BladeCenter unit
has failed. If it has, replace the fan.
v
Make sure the room temperature is not too high. (See
“Features and specifications” on page 5 for temperature
information.)
If the problem remains, have the blade server serviced.
BMC error
(baseboard
management
controller error)
The service processor 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
(nonmaskable
interrupt error)
A system board has failed.
1. Replace the blade server cover, reinsert the blade
server in the BladeCenter unit, and then restart the
server.
2. Check the system error log in the BladeCenter
management module for information about the error.
If the problem remains, have the blade server serviced.
Table 8. Processor board light path diagnostics LEDs
LED Problem Action
Light path
diagnostics LED
(green)
If this green LED does not light
when you press and hold the light
path diagnostics button on the
processor board, there might be no
power available to light the LED.
Replace the blade server cover and reinsert the blade
server in a powered BladeCenter unit; then, after the
blade server has been in the BladeCenter unit for several
minutes, remove it and try to light the light path
diagnostics LED.
If the problem remains, have the blade server serviced.
Processor x error
where x is the
number of the
microprocessor
that has an error
The microprocessor has failed. Make sure that the microprocessor indicated by the lit
LED is installed correctly. (See “Installing an additional
microprocessor” on page 29 for installation instructions.)
If the problem remains, have the microprocessor replaced.
Processor
mismatch error
The microprocessors do not match. Make sure that all of the microprocessors (1 through 4)
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.
DIMM x error
where x is the
number of the
DIMM that might
have an error
A memory error has occurred. Replace the DIMM indicated by the lit DIMM error 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 error log in the BladeCenter
management module for information about the error.
If the problem remains, have the blade server serviced.
