We upgraded our controler to ver 5 to cure an issue where the 1250 APs would not turn their radios on. The upgrade seemed to cure that issue but it looks to have come back. Has anyone seen this situation before. I am going to look at this in our lab tomorrow.
1252's require the 4.2 code or higher. Also the 1252's require more power than 15.4W. You can supply full 20W with any E-Series switches with a certain firmware. If connected to a 6509, there are other requirements needed to supply 16.8W. If you have a power injector or power cord, then you should be fine. Also make sure no one is pushing out a template in WCS that shuts off the radios.
