• First, replace the hard disk drive and install system software.
Always replace a faulty hard disk drive with a new hard disk drive. Transferring a hard disk drive from one imagePRESS
Server to another is incorrect and strongly discouraged.
• If the problem persists, reinstall the original hard disk drive in the system, and then replace the motherboard.
■ Motherboard cautions
IMPORTANT:
If you have exhausted all other troubleshooting remedies and determined that you need to install a new motherboard, be
sure to observe the following cautions:
• Do not transfer the BIOS chip from the old motherboard onto the new motherboard.
BIOS chips are not interchangeable.
• Do not reinstall system software at this time.
Reinstalling system software is not necessary when installing a new motherboard and can result in an error if done before
transferring options to the new motherboard. (described on

The imagePRESS Server can remain in Service Mode indefinitely. Use Service Mode to carefully verify the new motherboard
before transferring options to the new motherboard.
Transferring options to the new motherboard permanently customizes the new motherboard. Once customized, the
motherboard cannot be returned to inventory or installed in another imagePRESS Server. If the new motherboard does not
solve the problem in Service Mode, do not transfer options. Return the new motherboard and motherboard replacement
dongle to inventory.
• If you can verify in Service Mode that the new motherboard solves the problem that you are troubleshooting, transfer
options to the new motherboard using the motherboard replacement dongle included with the new motherboard.

motherboard kit.
