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 termination (see “SCSI Bus Termination” on page 1-21)
2. SCSI cable
3. Last SCSI device connected (CD-ROM drive, tape drive, etc.)
4. The graphics adapter, if the system console is defined as a graphical
display.
5. The riser card.
6. System board (See notes on page 2-1.)
7. 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 your service support person 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 1540A-1” on
page 2-22 in this MAP and follow the instructions for the new symptom.
