Juniper QFX Series User Manual

NOTE: If the AC OK LED and the DC OK LED are unlit, either the AC power
cord is not installed properly or the power supply fuse has failed. If the AC
OK LED is lit and the DC OK LED is unlit, the AC power supply is installed
properly, but the power supply has an internal failure.
