Using the LEDs to Determine the Problem

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.
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.
Table 5-1 summarizes the AP LEDs.
