Processor problems
Action:
Check the processor error LEDs ("System board LEDs" on page 18 ) or internal
health LED ("System LEDs and internal health LED combinations" on page 19 )
to identify if a processor failure occurred.
1. If the server does not boot, the internal health LED is red, one processor is
installed, and one processor error LED is illuminated:
a. Verify the VRMs are installed for each processor.
b. Verify the DIMMs are installed properly.
c. Remove all adapter boards and restart the server. If the server boots,
install adapter boards one at a time to determine which one prevents the
server from booting.
d. Replace processor 1. If the server restarts, the original processor has
failed.
e. If the server does not boot after following these steps, replace the system
board.
2. If the server does not boot, the internal health LED is red, two processors are
installed, and one processor error LED is illuminated:
a. Verify the VRMs are installed for each processor.
b. Verify the DIMMs are installed properly.
c. Remove all adapter boards and restart the server. If the server boots,
install adapter boards one at a time to determine which one prevents the
server from booting.
d. If the processor error LED is for processor 1, replace processor 1 with
the processor in socket 2 and restart the server. If the server boots, the
original processor 1 has failed and should be replaced.
e. If the processor error LED is for processor 2, remove it and restart the
server. If the server boots, processor 2 has failed and should be replaced.
f. If the server does not boot after the following these steps, replace the
system board.
