Using the LEDs to Determine the Problem
The LEDs on the AP show status and help you diagnose problems. After the AP is
powered up and completes its power-up self-test procedure, the LEDs indicate whether
the AP is functioning properly.
powered up and completes its power-up self-test procedure, the LEDs indicate whether
the AP is functioning properly.
When the power-up self-test diagnostics detect a failure in the AP or you suspect a
failure, rerun the self-test to verify that the failure can be repeated. Run the self-test by
unplugging the ac power cord and plugging it back in.

LEDs that blink do so in one of two modes:
•
Normal mode – At a variable (random) rate with varied intensity to indicate the
activity level during normal operation.
activity level during normal operation.
•
Error mode – At a constant (steady) rate and intensity to indicate an error.
