Basic Problem Solving

The LEDs on the Access Point (AP) show the status of the unit and help you diagnose

problems. After the AP is powered up and completes its power-up self-test procedure,

the LEDs indicate whether the unit 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.

Using the LEDs to Help Determine a Problem

Table 5-1 summarizes the Access Point LEDs.

Table 5-1: LED Summary Table

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.

• Error mode – At a constant (steady) rate and intensity (for example: ON, OFF,

ON, OFF, ON, OFF . . . ) to indicate an error.
