We have a mix of the AP's with and without Power Injector because only some switches have the POE.
On WLC what setting has to be checked on the Advanced Tab for the AP?
1. Some times AP gets installed with POI and after couple of weeks the radios go down. We have to make the change on the WLC advanced Tab of the AP by unchecking the Pre Standard and checking the Power Injector As installed and the radios come up.
2. Some times from the beginning the radio does not come up unless we make the above change.
