Fault Detection and Alarm Notification
• Fan failure: If either of the two cooling fans fails, the dedicated LED (Fan 1 or Fan 2) changes color
from green to red and an audio alarm sounds. The dedicated LED remains red for the failed fan unit
until it is fixed
The fan assembly can be hot-swapped if either fan fails. Dual fans provide redundant application
• High Temperature: If the chassis' interior temperature exceeds 65° C (149° F) (standard setting),
the LED changes color from green to red and an audio alarm sounds. The LED remains red until the
temperature falls below 63° C
Temperature select: The temperature can be set to four status levels by adjusting the switch on the
alarm board:
65° C (default setting), 55° C , 70° C and 75° C
• Audible Alarm: Speaker is activated (continous beep) as soon as a malfunction is detected and
sounds until the alarm reset button is pressed. The alarm reset button is on the front panel. However,
the alarm indicator will stay red until the fault condition is resolved.
• Self-test: Press the Alarm Reset button for 8 seconds. The alarm board will self-test automatically for
all functions. The alarm board can also monitor the temperature sensor IC. If the sensor has failed or
there is no connection, the speaker will sound off as "Beep x Beep x ...".
