System Alarm LED
There are two FAIL LED design on the Backplane to indicate Fan Fail and Over-
Temperature. Lead 2.0mm 8-pin header CN1 to front panel for indicating system fault.
Fan Fail:
When any fan module RPM is lower than 75% of the expected speed the Fan Fail is
triggered and the Fail LED blinks in 0.5Hz rate. Goes off when the issue is resolved or
disappeared.
Overheat:
When the system temperature at the backplane area is going beyond 45
°C
the Temp Fail
triggered and Fail LED blinks in 2Hz rate. Goes off when temperature is going under 45
°C.
Overheat & Fan Fail:
Fail LED stays steady on when both events triggered at the same time.
Note:
When the system alarm is triggered, the Buzzer beeps along with it and stops
beeping when alarm is disappeared.
1 short beep(B—B—B) stands for Fan Fails
2 short beeps(BB—BB—BB) stand for Over-Temperature
Press Mute Button to disable buzzer beeping and will be retriggered when either
failure occurs again.
