Chapter 3 Operation
When the system power is on, the power LED is always Green.
When the power LED is RED, it indicates a redundant power supply module failure.
To stop the alarm beeping, press the Alarm Reset button. Examine the redundant
power supply module right away and replace the failed module with a good one.
When the fan LED is RED, it indicates a failed cooling fan, and the alarm is also acti-
vated. To stop the alarm beeping, press the Alarm Reset button and then replace the
failed fan with a good one immediately.
If the temperature LED is RED, it means that inside of the chassis has overheated
(more than 50° C). An audible alarm will be activated. To stop the alarm beeping,
press the Alarm Reset button. Inspect the fan filter and the rear section of the chas-
sis immediately. Make sure the airflow inside the chassis is smooth and not blocked
by dust or other particles.
