Power Injector LEDs
The power injector contains three LEDs to provide status information on the wired Ethernet link, the
bridge Ethernet link, and the bridge status. When the power injector is powered up, it sends a constant
discovery tone on the dual-coax cables to the bridge. When the bridge is connected to the dual-coax
cables, it returns the discovery tone to the power injector. When the power injector detects the returned
discovery tone, it applies +48 VDC to the dual-coax cables to the bridge.
When power is applied to the bridge, the bridge activates the bootloader and begins the POST
operations. The bridge begins to load the IOS image when the Post operations are successfully
completed. Upon successfully loading the IOS image, the bridge initializes and tests the radio.
The power injector LEDs are shown in Figure 8.
