Power Injector

When the power injector is powered up, it applies 48-VDC to the dual-coax cables to the access
point/bridge.
When power is applied to the access point/bridge, the unit activates the bootloader and begins the POST
operations. The access point/bridge begins to load the Cisco IOS image when the POST operations are
successfully completed. Upon successfully loading the image, the unit initializes and tests the radio.
