Factory-Installed Drive Devices
Use this check procedure to test any factory-installed drives.
Attention: The customer may have customized settings in the Setup Utility
(other than default settings) on the computer you are servicing. Running the
Setup Utility might alter those settings. Note the current settings and verify
that the customer settings are in place when service is complete.
Note: If you cannot access the hard disk drive or load a diskette from drive
A or load a CD from the CD-ROM drive, make sure the Setup Utility
has the startup sequence set with
Diskette , CD-ROM , and Hard Disk
enabled.
Insert the Diagnostics CD in the CD-ROM drive. Refer to Step 006 on
page 2-43 to check Hardware Configuration.
If the number of diskette drives shown in the Installed Devices list is
not correct:
1. Check the installation of the drive ribbon cable to the system board.
Note: If the drive is installed the Access Station, check the drive ribbon
cable from the system board to the host card and from the drive
to the client card. Also check the Access Station cable.
2. Check the voltages to the diskette drive with the power on (see “Power
Supply” on page 2-35).
3. Check the installation of the Access Station cable on the system board.
4. Try to correct the drive setting in the (SETUP) option in the Setup Utility.
5. Run the “Diagnostics Device Presence Test” on page 2-43.
If you can correct the Installed Devices list, but cannot complete the
Diagnostics test for that device, replace FRUs, in the following order, until
the problem goes away:
1. Diskette drive
2. Diskette drive cable (if continuity check fails)
3. Access Station host card.
4. Access Station client card.
5. Access Station cable (Canada and Japan only)
6. Access Station
Note: The Access Station is replaced as a FRU in the U.S. only.
Canada models can order replacement parts for the Access
Station.
