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 informaon about the status of the AC power supply. There are two LEDs on the
cra interface that also display the power supply status. In addion, a power supply failure triggers the
major alarm LED on the cra interface.
