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.

Blinking Green — — Transmitting and receiving Ethernet packets

between the power injector and the bridge.

Amber — — Power injector internal memory

error—disconnect and reconnect the power

injector power plug. If the problem continues,

contact technical support for assistance.

— Green — Bridge successfully passed Power On Self Test

(POST) and loaded the IOS image.

— Blinking Green — Bridge power is active and the bridge is loading

IOS image or POST operation has started.

— Blinking Amber —– Bridge has not been detected and bridge power

is not active. This might be caused by bad

connections or a defective cable or connector.

Verify that the dual-coax cables are connected

correctly to the power injector, grounding

block, and bridge. If the cables are connected

correctly, contact technical support for

assistance.

Amber Amber Amber Power injector internal memory

error—disconnect and reconnect the power

injector power plug. If the problem continues,

contact technical support for assistance.

Off Amber Off Bridge is resetting the configuration to defaults;

mode button has been depressed more than 2

seconds but less than 20 seconds.

— Red — Image recovery mode, downloading new image;

mode button pressed more than 20 seconds.

Red Red Red Power injector internal memory
