Checking the Top Panel Indicators Chapter 22 Troubleshooting Table 22-4 LED Indications (continued) Ethernet LED Status LED Radio LED Red Amber Red — Loading Firmware error—disconnect and reconnect the power injector power. If the problem continues, contact technical support for assistance. — — Off — Normal operation. — — Blinking green — Transmitting and receiving radio packets—normal operation. — — Blinking amber — Maximum retries or buffer full occurred on the radio interface—disconnect and reconnect the power injector power jack. If the problem continues, contact technical support for assistance. — — Amber — Radio firmware error—disconnect and reconnect power injector power.If the problem continues, contact technical support for assistance. — — — Amber blinking — — — Amber Associated (non-root mode). — — — Green blinking Not associated (non-root mode). The access point/bridge attempts to associate with a root bridge for 60 seconds 1 . Not associated (root mode). The access point/bridge attempts to associate with a non-root bridge indefinitely. — — — Green Associated (root mode). — — — Red Overcurrent or overvoltage error—disconnect power to the power injector, check all coax cable connections, wait approximately 1 minute, and reconnect power. If error continues, contact technical support. 1. Preconfigured bridges search indefinitely. Install LED Meaning The access point/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. The LED blinking error codes are described in Table 22-5. Table 22-5 LED Blinking Error Codes LED Blinking Codes First Digit Second Digit Description Ethernet 2 1 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. 22-12 Cisco IOS Software Configuration Guide for Cisco Aironet Access Points OL-8191-01
Chapter 22 Troubleshooting Checking the Top Panel Indicators Table 22-5 LED Blinking Error Codes (continued) LED Blinking Codes First Digit Second Digit Description Radio 1 2 Radio not detected—contact technical support for assistance. 1 3 Radio not ready—contact technical support for assistance. 1 4 Radio did not start—contact technical support for assistance. 1 5 Radio failure—contact technical support for assistance. 1 6 Radio did not flash its firmware—contact technical support for assistance. 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 IOS image when the Post operations are successfully completed. Upon successfully loading the IOS image, the unit initializes and tests the radio. The power injector LED is shown in Figure 22-8.
