3.2 Fan Speed Adjustment
1. There are two hot-swappable 80×80×25 mm cooling fans for ventilation at rear
of NA762TB3. After loosening the two thumbscrews on fan module, the fan
module can be detached from storage.
2. The rear 80×80×25 mm cooling fans speed can be adjusted. As fan module is
detached from storage, there are four sets of jumpers labeled with 6V, 8V,
10V, 12V from left to right on the backplane inside NA762TB3. The default
setting is the jumper being placed over pin 7 and 8 for label 6V for slowest
speed. The speed increases from label 8V to label 12V. As jumper is not placed
over pins, the fan will spin at 12V full speed.
