The System Status LED shows as follows:
When the PWR LED is RED, it indicates a redundant power supply fail-
ure. To stop the alarm buzzer, press the Alarm Reset button. Please check
out the redundant power supply right away and replace failure power sup-
ply module with a good one.
When the FAN LED is RED and blinking, it indicates a failing cooling fan.
An audible alarm is also activated. To stop the alarm buzzer, press the
Alarm Reset button then replace the fan immediately.
If the TEMP LED is RED and blinking, the system detects rising tempera-
ture inside the chassis. An audible alarm is activated. To stop the alarm
buzzer, press the Alarm Reset button. Inspect the rear section and fan fil-
ter immediately. Make sure airflow inside the chassis is smooth and not
blocked by dust or other particles.
