See Figure 8-15.

8.5.2 Replacing the SCSI Cable/Backplane

1. Route the SCSI cable under the three cable clips in the base of the chassis

and through the opening near the front edge of the system board.
See Figure 8-15.

2. Connect the SCSI cable to the system board at J2602.

3. Position the SCSI backplane on the disk drive bay so the SCSI backplane

slots sit on the tabs.
See Figure 8-16.
