Note: If the INPUT OK LED and the OUTPUT OK LED are unlit, the AC power cord is not installed properly or the power supply fuse has failed.
If the INPUT OK LED is lit and the OUTPUT OK LED is unlit, the AC power supply is not installed properly or the power supply has an internal failure.
If the FAIL LED is lit, the power supply has failed and must be replaced. If the FAIL LED is blinking, add a power supply to balance the power demand and supply.
