I have Cisco Wlc 9800 , i add AP Cisco C9115AXE-E with success and interface 5 GHZ is enabled and
operation status is green
But in AP AIR-AP2802I-E-K9 i added in wlc but the interface radio for the both 2.4 GHZ and 5GHZ is red
see below these screenshots
how to solve the problem so that the AP 2802I must green like the AP C9115
As I can see from the screenshot you shared, you are using a POE injector. for 2802 to work you need POE+ (802.11at) capable power injector or POE+ capable switch. Below is from the Data sheet
Input power requirements
● 802.3at PoE+, Cisco Universal PoE (Cisco UPOE ®)
● 802.3at power injector (AIR-PWRINJ6=)
So please make sure that you either change the POE injector or connect the AP to an switchport with POE+ or higher capability.
According to the log at the AP level and Switch cisco 3560
the problem is at the switch level (poe problem) you have to change the switch so that the AP will be functional and activate the 5 and 2.4 GHZ radio
And suite a log is Bug AP1562 PoE negotiation failed with CDP
Did you physically verify that the AP is directly connected to a POE capable switch? As per the screenshot it looks like it is connected to a POE injector as well.
If you are using a compatible POE injector to power an AP connecting to a POE capable switch, it is must that you disable POE in the switchport, let the POE injector power the AP. Otherwise it may create POE negotiation issues.
So from the switch "no power inline"
@Arshad Safrulla yes i use compatible power injector for AP 2802I , and i disable POE in the switchport
Always the same problem : please find below log for AP Cisco 2802

It's a bug Cisco is annonced, if i understand correctly you should change a switch WS-C3560-48PS
