Checking the Top Panel Indicators
Note It is expected that there will be small variations in LED color intensity and hue from unit to unit. This is
within the normal range of the LED manufacturer’s specifications and is not a defect.
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 22-8.
