ACP-4010 User Manual 18
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 beep, 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 activated. To stop the alarm beeping, press the Alarm Reset but-
ton and then replace the failed fan with a good one immediately.
If the temperature LED is RED, it means that inside of the chassis is
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 chassis immediately. Make sure the airflow
inside the chassis is smooth and not blocked by dust or other particles.
If the LAN1/LAN2 LED stays GREEN, it means the network connection
works normally. When the data is transmitting through the network, the
LAN LED starts blinking. When the LAN1/LAN2 LED fails to light up,
inspect the LAN cable and the connection.
