Devices List
Follow the instructions on the panel for the installed devices list.
Attention:
A customized setup configuration (other than default settings) might exist on the
computer you are servicing. Running the Configuration/Setup Utility program (see
“Service Processor Configuration / Setup Utility” on page H-8) might alter those
settings. Note the current configuration settings and verify that the settings are in
place when service is complete.
If the number of diskette drives shown in the installed devices list is not
correct
, perform the following steps:
1. Restart the computer.
2. Run the Configuration/Setup Utility program to correct the drive information.
3. Run the diagnostic tests.
4. If you cannot correct the drive information, replace FRUs, in the following order,
until the problem goes away:
Diskette drive
Diskette-drive cable
System board
If the number of hard disk drives shown in the installed devices list is not
correct
, perform the following steps:
1. Check the hard disk drive jumper settings. All supported hard disk drives use
jumpers or tabs to set drives as either primary or secondary. Refer to the
jumper instructions that came with your hard disk drives.
2. Check the voltages to the hard disk drives (see “Power Supply” on page 3-20).
3. Restart the computer and check the configuration.
If the first drive is missing, replace the primary drive.
If any other drive is missing, replace that drive.
If all drives are missing, replace the primary drive.
If the problem remains, replace the drive cable.
If the problem still remains, replace the system board.
If any other adapter or device is missing from the installed devices list, run
the Configuration/Setup Utility program
. Check to see if any adapter or device
is set to a conflicting address with any other adapter or device. Also be sure that
any adapter or device missing from the list is not set to “disabled.”
Note: If the device is still missing from the list, run the diagnostics provided with
that device.
