Chapter 7 Troubleshooting
Checking the LEDs
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.
— Blinking
green
— — Root bridge mode—no remote bridges are associated.
Non-root bridge mode—not associated to the root bridge.
If all bridges are powered up, this could be caused by incorrect SSID
and security settings or improper antenna alignment. You should check
the SSID and security settings of all bridges and verify antenna
alignment.
If the problem continues, contact technical support for assistance.
