Table 5-13 Intermittent Problems
Symptom Cause and Action
A problem occurs only
occasionally and is difficult to
detect.
1. Verify the following items:
a. All cables and cords are connected securely to the rear of the
device and attached hardware options.
b. When the device is powered on, air is flowing from the rear
of the device at the fan grille. If there is no airflow, the fan is
not working. This causes the device to overheat and shut
down.
c. Ensure that the SCSI bus and devices are configured correctly
and that the last external device in each SCSI chain is
terminated correctly.
2. Check the system error log.
