• Reset button cable
• Power button cable
• Front panel USB port cable
• UIB cable
• DVD data cable

Verifying new motherboard installation and transferring options
After you install a new motherboard and reassemble the system, do the following:
• Verify all functionality by using the motherboard replacement dongle to enter Service Mode. (Service Mode is not
indicated on the monitor or LCD, but is entered once you power on with a new motherboard installed and the
motherboard replacement dongle installed on a USB port.)
Service Mode is a temporary state that allows you to make sure that the motherboard solves the problem that you
are troubleshooting. Service Mode is exited automatically when you expend the motherboard replacement dongle
to transfer options to the new motherboard (see “Entering Service Mode” on page 55).
Note: Features of Fiery Impose-Compose are not available while in Service Mode.
