Replacing the Diagnostic Board
You will only remove the diagnostic board from the HP Server when it is defective and requires replacement.
The diagnostic board is enclosed in a protective cover. Remove the cover and save it for the replacement
diagnostic board.
NOTE When installing the fan cage, be very careful to move all cables out of the way so they
don’t get pinched when sliding the fan cage in on the rails.
When installing the fan assembly, make sure the SCSI cable is not over the connector
where the fan assembly plugs in.
