Are all the power supplies plugged in? Is the power turned on to the power strip or
outlet? Do you have a blown fuse or breaker?
•
Is the system functioning normally? If so, the power LED may be defective, the
cable from the front panel to the fan board may be loose, or the cable from the fan
board to the baseboard may be loose.
