Step 5
The CD-ROM drive, SCSI cable, SCSI adapter, graphics adapter, or the system board
is most likely defective. A TTY terminal attached to the serial port also can be used to
determine if the graphics adapter is causing the problem. This determination is done by
removing the graphics adapter, attaching a TTY to the serial port, and retrying
standalone diagnostics. If the standalone diagnostics load, replace the graphics
adapter.
1. Replace the CD-ROM drive.
2. Replace the SCSI cable.
3. If the CD-ROM drive is attached to a SCSI adapter rather than the integrated SCSI
on the system board, replace the SCSI adapter.
4. Replace the system board.
5. If you replaced the indicated FRUs and the problem is still not corrected, or the
above descriptions did not address your particular situation, go to "MAP 1540:
Minimum Configuration" on page 57.
6. Go to "MAP 410: Repair Checkout" in RS/6000 and Eserver pSeries Diagnostic
