7-22 Dell PowerEdge 2450 Systems Installation and Troubleshooting Guide
10. Turn off the system, including any attached peripherals, and disconnect the AC
power cable from its power source. Then open the computer doors.
11. Remove the tape drive. Then verify that the tape drive is configured for a unique
SCSI ID number and that the tape drive is terminated or not terminated as appro-
priate. See the documentation for the tape drive for instructions on selecting the
SCSI ID and enabling or disabling termination.
Is the tape drive configured correctly?
Ye s . Go to step 14.
No. Go to step 12.
12. Reconfigure the tape drive's SCSI ID and termination settings as appropriate.
Reinstall the tape drive, close the computer doors, and reconnect the system to
AC power and turn it on.
Is the problem resolved?
Ye s . The tape drive was configured incorrectly. You have fixed the problem.
No. Go to step 13.
13. Turn off the system, including any attached peripherals, and disconnect the AC
power cable from its power source. Then open the computer doors.
14. Replace the SCSI cable that connects the tape drive to the SCSI host adapter.
Close the computer doors, and then reconnect the system to AC power and turn
it on.
Is the problem resolved?
Ye s . You have fixed the problem.
No. See Chapter 11, “Getting Help,” for instructions on obtaining technical
assistance.
#$"+!*
Hard-disk drive problems can be caused by a number of conditions, including prob-
lems with the drive itself, the SCSI backplane board, the optional SCSI daughter
boards, or a cable connected to the SCSI backplane board.
The SCSI backplane board monitors the SCSI hard-disk drives connected to the back-
plane board. In the event of a drive failure, systems using the optional integrated
RAID controller or optional PERC 2 controller card will issue the following signals
using the drive indicator lights adjacent to each SCSI hard-disk drive:
If a drive shows signs of imminent failure, the drive online indicator stays on and
the drive failure indicator blinks on briefly each second.
If a drive has failed, the drive online indicator turns off. The drive failure indicator
turns on, and blinks off briefly each second.
