 Troubleshooting

Symptom Charts/Hard Drive - 16

 

Single internal hard 

drive does not 

operate; drive 

doesn’t spin

1 Replace hard drive power cable.

2 Replace hard drive. If problem resolved, reinstall SCSI 

device driver and system software.

3 Replace power supply.

No internal SCSI 

drives operate (PM 

8600/9600) or no 

internal SCSI devices 

on a single bus 

operate (WS 9650)

1 Verify there are no duplicate SCSI device addresses on a 

single SCSI bus. (Refer to Basics chapter for detailed 

explanation of SCSI IDs used in WS 9650.)

2 Disconnect external SCSI devices and check for proper 

termination. Only last device in SCSI chain should be 

terminated. 

3 Check internal SCSI devices for proper termination. In PM 

8600 or 9600, last connector on Fast SCSI-2 cable attaches 

to rear internal hard drive, which is terminated. In WS 

9650, Fast SCSI-2 cable should have terminator on last 

connector or last connector should be attached to terminated
