Wireless AP boot error

DevilWAH

Hi can any one tell me what the following means on a WLC controller for when a AP is booting?



2013 Mar 21 22:47:02
ERROR
AP 16 network: Check AP Static Configuration.


2013 Mar 21 22:47:02
ERROR
AP 16 network: Booted via fallback


2013 Mar 21 22:47:02
CRIT
AP_NOTICE: image delivered OK on AP 16



the only static config is a static VLAN assigment.

what does it mean by "Booted via fallback"

Cheers
