P2
A system board and chassis assembly error
has occurred. A microprocessor failure shows
up as a system board and chassis assembly
error.
1. Replace the blade server cover, reinsert the
blade server in the BladeCenter unit, and
then restart the blade server.
2. Check the management-module event log
for information about the error.
3. Replace the system board and chassis
assembly, as described in “Replacing the
FRU system-board and chassis assembly”
on page 264.
Isolating firmware problems
You can use this procedure to isolate firmware problems.
To isolate a firmware problem, follow the procedure until the problem is solved.
1. If the blade server is operating, shut down the operating system and turn off the blade server.
2. Turn on the blade server.
If the problem no longer occurs, no further action is necessary. You are finished with this procedure.
3.
If the blade server boots up far enough to allow the installation of server firmware updates, check for
appropriate updates and install them.
If you install updates, reboot the server and see if the problem still exists. If not, you are finished with
this procedure.
