When the system power is on, the power LED will remain blue.
When the power LED is RED, it indicates a power supply failure. To stop the alarm,
press the Alarm Reset button. Examine the power supply right away and replace the
failed power supply with a new one.
When the fan LED is red, it indicates a failed system fan, and the alarm is activated.
When the fan LED is pink, it indicates a failed CPU cooler and the alarm is also acti-
vated. To stop the alarm press the Alarm Reset button and then replace the failed
fan with a functioning one immediately.
If the temperature LED is red, it means that it has overheated inside the chassis
(more than 55 °C;131 °F). And if the temperature LED is pink, it means that it is over-
heated on the CPU card (more than 70 °C/158 °F). An audible alarm will be acti-
vated. To stop the alarm from beeping, press the Alarm Reset button. Inspect the fan
filter or temperature of the CPU card and the upper section of the chassis immedi-
ately. Make sure the airflow inside the chassis is smooth and not blocked by dust or
other particles.
Note! The detectability of the CPU cooler or CPU temperature depends on the
design of the individual CPU cards.
When the HDD LED is blinking, it indicates the data access from HDD. And when
