I have a LAP-1130AG plugged into a 3750G port. As the 3750G is non-PoE, the LWAP has an AC power-pack/brick plugged in, but still generates this error in the WiSM syslog:
LWAPP-3-AP_POWER_ERR, and refuses to power up the radios.
A search on cisco.com for this error code tells me to search on cisco.com for an answer. Duh.
How to I tell the AP that it truly does have enough Power to turn on the radios?
On an autonomous AP, you can do a power inline overide command.
I have a WiSM, and WCS (former WLSE).
