Step 1540-11
The system is working correctly with this configuration. One of the SCSI devices that
you disconnected may be defective.
1. Make sure the diagnostic CD-ROM is inserted into the CD-ROM drive.
2. Turn off the power and remove the power cords.
3. Plug the SCSI cable into the SCSI connector on the system board.
4. Plug in the power cords and wait for OK on the operator panel display.
5. Turn on the power.
6. After the keyboard indicator is displayed, press the F5 key on the directly attached
keyboard or the number 5 key on an ASCII terminal keyboard.
7. Enter the appropriate password if you are prompted to do so.
Is the ″Please define the System Console″ screen displayed?
NO One of the FRUs remaining in the system unit is defective.
In the following order, exchange the FRUs that have not been exchanged:
1. SCSI cable
2. Last SCSI device connected (disk drive, tape drive)
3. System board (see notes on page 35)
4. Power supply.
Repeat this step until the defective FRU is identified or all the FRUs have been
exchanged.
If the symptom did not change and all the FRUs have been exchanged, call
service support for assistance.
If the symptom has changed, check for loose cards, cables, and obvious
problems. If you do not find a problem, return to “Step 1540-1” on page 64 in
this MAP and follow the instructions for the new symptom.
YES Repeat this step, adding one SCSI device at a time, until all the SCSI devices
that were attached to the integrated SCSI adapter, except the backplane, are
connected and tested.
If the SCSI 6-pack is installed, go to “Step 1540-12” on page 73.
If the SCSI 6-pack is not installed, go to “Step 1540-14” on page 75.
