Checking Power

You can verify the availability of power to the bridge by checking the power injector LEDs (see Figure 6-2):

Power LED

Green color indicates 48 VDC is available to the power injector (see Figure 6-2).

Off indicates 48 VDC is not available to the power injector—verify that the power module is connected to the power injector and to an AC receptacle and that AC power is available.

Uplink Activity LED

Green or blinking green color indicates the bridge is operating.
