Hi, I recently bought 15 new AP Aironet 3500 (AIR-CAP3502I-A-K9) and connect to 3 different Cisco Catalyst 2960S. All of these get powered at boot with 15.4 Watt but after the boot process, they all drop to 14.5W and the LED blinking all color to say AIR-CAP3502I-A-K9.
I already have other same AP connected to a 2960S switch with no problem. Different length, longest run maybe 200 feet, so not a length problem.
What can be the problem?
All the AP is LWAPP connected to a Wism controller on a 6509 chassis.
Yes we have enough power, some switch has ip phone, but on a new switch, 2960-48ports, we have 4 new AP, who doesn't work and 1 ip phone 7911. 2 or 3 server who doesn't need power. If I look all my switch with show power inline, all give me more than 150 Watt remaining. I try to set power inline consumption 15400 to 15.4W but nothing change, I shutdown the port, reenable it and the AP still blinking to say enough inline power but with that the show power inline stay at 15.4
If I disable cdp, in show power inline I see 15.4 Watt with Ieee PD device but the AP didn't join the controller and blink red blue green.
I found the problem with the console log. It was a DNS problem, we change our AD domain and DNS and I didn't add CISCO-CAPWAP-CONTROLLER is the new DNS, so the AP didn't find his controller. I update the DNS and all the AP goes online and added to WCS.
