The Fan Fault LED can also indicate a faulty fan or a faulty connection. This condition may also be evident by a noticeable increase in the speed of the remaining system fans. If this occurs, power down the server and reseat the fan cables. Restart the server. When video is initialized, press the reset button. This resets the fault indicator lights. If the fan speeds do not normalize, restart the server a second time. If the fan speed normalizes, one of the fans was partially disconnected, causing the LED to illuminate.
