Attention:
To help ensure proper cooling and
system reliability, two microprocessors and two
heat sinks are required on the system board in
the blade server at all times. The
microprocessors and heat sinks on the system
board are not replaceable. Therefore, if a
microprocessor or heat sink becomes
defective, you must replace the system-board
assembly. Contact a service support
representative for assistance.
1. To verify the error, replace the blade-server
cover, reinsert the blade server in the
BladeCenter unit, and then restart the
server.

system-board assembly. Contact a service
support representative for assistance.
