Lee, I have seen Poe power problems when installing 1250's on 3750E switches. If you use the command "power inline port maximum 20000" on the port then the port will get the maximum power and none of the radios will shut down.... My two cents. -Jeff Legge Radford University.

Wondering if anyone else experiences this. I'm working now to see if it is isolated to a single Catalyst switch or if it is more widespread. Frequently, we will get a report that a radio on an LWAPP AP is down. Sometimes the alarm is for insufficient drawn power, sometimes not- just radio down. Better than 90% of the time, a simple AP reboot will not do any good- we have to lie to the controller that the AP has a PoE injector installed, even though the AP is on a switch. Usually the condition is onesy-twoesy- not every AP on a given switch (although this morning we saw that) and often happens on APs that are obviously not taxing a given switch's available PoE output. I am opening a case as we see this enough to be of concern, but also am wondering if anyone else has experienced this in a given environment where LWAPP APs are powered by Cisco PoE switches?
