SERVICE PROCEDURES 65
Replacing the motherboard
Follow the procedures in this section to replace the motherboard. Failure to follow the
instructions in this section may corrupt the system (not easily repaired in the field) or result in
an incomplete installation (see “Error messages” on page 76).
Troubleshooting cautions
• Before deciding to install a new motherboard, consult “Troubleshooting” on page 110.
• Inspect all cables and internal components as described on pages 112 and 113. If these
inspections do not solve the problem, locate symptoms in the troubleshooting table
beginning on page 121, and perform the suggested actions in the order listed.
• If troubleshooting strategies (checking cables and connections, reinstalling system
software, and so forth) do not solve the problem and you suspect either one of the HDDs
or the motherboard is faulty, always troubleshoot in the following order:
(Troubleshooting in the wrong order will cause the system to malfunction. In general, it is
highly unlikely that one of the HDDs and the motherboard are both defective; therefore,
avoid replacing a HDD and the motherboard to solve one problem.)
– Replace one of the HDDs and install system software.
Always replace a faulty HDD with a new HDD. Transferring a HDD from one
imagePRESS Server to another is incorrect and strongly discouraged.
– If the problem persists, reinstall the first HDD you removed earlier, replace the other
HDD, install system software again, and then re-check the system.
– If the problem persists, perform other procedures, such as replacing the motherboard.
(Make sure to thoroughly review the motherboard replacement procedure beginning
on page 65.)
