3.1.2 LED Indicators for System Status
The LED display on the front door shows a series of indicators that are grouped into
two categories for System Status and Power Voltage Status.
Figure 3.2 Front LED panel
The following table describes the LED indicators for System Status.
When the system power is on, the PWR LED is always Green . When the PWR 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 beep, press the Alarm Reset button and then replace
the failed fan with a good one immediately.
If the
TEMP LED is RED , it means that the inside of the chassis has overheated. An
audible alarm will be activated. To stop the alarm beep, press the Alarm Reset but-
ton. 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.
