Power Injector LEDs Chapter 19 Troubleshooting The bridge uses a blinking code to identify various error conditions. The code sequence uses a two-digit diagnostic code that starts with a long pause to delimit the code, followed by the LED flashing red to count out the first digit, then a short pause, followed by the LED flashing red to count out the second digit (see Table 19-2). Table 19-2 Bridge LED Blinking Error Codes LED Ethernet Radio Blinking Codes First Digit Second Digit 2 1 1 2 1 3 1 4 1 5 1 6 Description Ethernet cable problem-verify that the cable is properly connected and not defective. This error might also indicate a problem with the Ethernet link. If the cable is connected properly and not defective, contact technical support for assistance. Radio not detected-contact technical support for assistance. Radio not ready-contact technical support for assistance. Radio did not start-contact technical support for assistance. Radio failure-contact technical support for assistance. Radio did not flash its firmware-contact technical support for assistance. 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. 19-4 Cisco Aironet 1400 Series Wireless Bridges Software Configuration Guide OL-4059-01
