Step 1540-10

1.Make sure the diagnostic CD-ROM is inserted into the CD-ROM drive.

2.Turn off the power.

3.Plug the SCSI cables (J4 and J33) into the SCSI connectors on the system board.

4.Disconnect the signal and power connectors from all the SCSI devices except the CD-ROM drive.

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 server is defective.

 

In the following order, exchange the FRUs that have not been exchanged:

 

1. SCSI cable

 

2. Last SCSI device connected (CD-ROM drive, tape drive, and so on)

 

3. Graphics adapter (if the system console is defined as a graphical

 

display)

 

4. Riser card

 

5. System board (see note 3 on page 2-1).

 

6. 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 1540-1”on

 

page 2-18,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 are connected

 

and tested.
