Expansion enclosure Verify that:
1. The cables for all external SCSI options are connected correctly.
2. The last option in each SCSI chain, or the end of the SCSI cable, is terminated
correctly.

work now.
Other devices Call for service.
Problems such as broken cover
locks or indicator lights not
working.
Intermittent problems Verify that:
1. All cables and cords are connected securely to the rear of the system and
attached options.
2. When the system is turned on, air is flowing from the rear of the system at the
fan grille. If there is no air flow, the fan is not working. This causes the system
to overheat and shut down.
3.
Ensure that the SCSI bus and devices are configured correctly and that the last
external device in each SCSI chain is terminated correctly.
If the items above are correct, call for service.
A problem occurs only
occasionally and is difficult to
detect.
Keyboard, mouse, or
