AC Power Supply LEDs in an EX9214 Switch

An AC power supply has four LEDs on its faceplate: AC-1 OK, AC-2 OK, DC OK, and PS FAIL LEDs.
These LEDs display information about the status of the AC power supply. There are two LEDs on the
craft interface that also display the power supply status. In addition, a power supply failure triggers the
major alarm LED on the craft interface.
