Step 5
The CD-ROM drive, SCSI cable, SCSI adapter, graphics adapter, or the primary I/O planar 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 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 primary I/O planar.
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 110.
6. Go to ″MAP 0410: Repair Checkout″ in RS/6000 and Eserver pSeries Diagnostic Information for
Multiple Bus Systems
