3.2.1 LED indicators for System Status
Six LEDs are placed on the left side of the front panel to indicate system health and
activity. Please refer to Table 3.1 for the LED definition summary.
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 working one.
When the fan LED is RED, it indicates a failed cooling fan, and the alarm is also acti-
vated. To stop the alarm beep, press the Alarm Reset button and then replace the
failed fan with a working one immediately.
If the temperature LED is RED, the inside of the chassis is overheated (more than
50°C). An audible alarm will be activated. To stop the alarm beep, 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 nor-
mally. When the data is transmitting through network, the LAN LED turns into blink-
ing. When the LAN1/LAN2 LED fails to light up, inspect the LAN cable and the
connection.
