    AC Power Supply LEDs in an EX9200 Switch

    An AC power supply has three LEDs on its faceplate. These LEDs display information about the status of the AC power supply. The power supply status is also reflected in two LEDs on the craft interface. In addition, a power supply failure triggers the major alarm LED on the craft interface.

    Table 1 describes the LEDs on an AC power supply in an EX9200 switch.
