Power Injector
The bridge LED blinking error codes are described in Table 8-2.
Power Injector
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 LED is shown in Figure 8-2.
