About WARPv3's Fan
Dear Sir,
We have three WARPv3 boards.
Now one of WARPv3's fan is not work.
But the fan is not bad. It can control by other WARPv3 board.
How to solve this problem?
Best Regards,
Paul

Re: About WARPv3's Fan
The fan is powered directly from the external 12V supply. Verify that a jumper is installed across pins 1-2 of J5 (3-pin header labeled "Fan Speed" on the PCB). If this jumper is missing the fan will be unpowered.

Re: About WARPv3's Fan
We measured the voltage of 3-pin header (J5) by multimeter.
pins 1-2: 12v
pins 2-3: 0.01v
The fan still can not turning .
But I think its fan is good. Because it can work with other WARPv3 board.

Re: About WARPv3's Fan
Sorry, J5 was a typo above. The "FAN SPEED" header is J9. A shunt must be installed across pins 1-2 of J9 for the fan to run at full speed.
What is the voltage across pins 1-2 of J8, the header where the fan cable is connected?

That's a different problem - if the LED is off either the LED is burned out or the voltage regulator (3.3v) driving it has failed. You can confirm this by measuring the voltage at the test point adjacent to the LED. If it's a hardware issue please follow up with support[at]mangocomm.com to arrange repairs.
