3.1.2 LED indicators for System Status

Figure 3.2: The LEDs on the front panel

Six LEDs (shown as Figure 3.2) are placed on the front panel of the ACP-

4320 chassis to indicate the system health and activity. Please refer to

Table 3.1 for the LED definition summary.

If the system is connected with a single PS/2 power supply, the Power

LED is always Green when power on.

When the PWR LED is RED, it indicates a redundant power supply fail-

ure. To stop the alarm buzzer, press the Alarm Reset button. Then, check

out the redundant power supply right away and replace the failed power

supply module with a good one.

If the TEMP LED is RED and blinking, it means that the system detects

an overly high temperature in the chassis. An audible alarm is activated.

To stop the alarm buzzer, press the Alarm Reset button. Inspect the fan

filter and the rear section of the chassis immediately. Make sure airflow

inside the chassis is smooth and not blocked by dust or other particles.

When the HDD LED is Green and blinking, it indicates some data is

written into or read from the HDD. When it becomes no light, it indicates

no data write/read is under proceeding.
