Intermittent Problems
Action
A problem occurs only

difficult to detect.
Verify that:
1. All cables and cords are securely connected 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 grill. If there is no
air flow, the fan is not working. This causes the
system to overheat and shut down.

terminated correctly. (See “SCSI Drives” on
page 159 for more information about SCSI
terminators.)
If the items above are correct, have the system serviced.
