Media Console Drive Devices
Problems with the 3.5-in. diskette Drive, the CD/DVD-ROM drive, keyboard,
mouse, the On/Off switch, or the hard disk drive LED might be caused by
the Media Console.
Multiple error codes can also be the result of a loose Media Console cable
or defective host or client cards. If the system unit powers up with some or
all of the following POST error codes, the Media Console might be at fault.
Depending on service procedures, replace either the Media Console FRU
parts or the Media Console unit.
If you receive multiple POST codes:
1. Check the installation of the Media Console cable on the host card.
2. Check the installation of the cable from pin J33 on system board A-1 or
pin J23 on system board A-2. See “System Board Layout—Type A-2”
on page 5-5 for more information.
3. Check the installation of the power connector from the power supply to
the host card.
If the problems persist see “Diagnostic Aids” on page 3-1 for more
information.
