New APs don't show up on Aruba controller

We have a new Aruba virtual controller for new wireless access points: I've added two new access points, for a total of 13. Two don't show up under active access points, only 11 show up. The switches are set up the same as all the others: vlan 5 for AP Management, vlan 3 for Guest, and vlan 10 for secure wireless.  One of the access points is on a switch that has 9 other APs that do show up and work. When I look in the Maintenance option on the controller, and then the Configuration tab, I can see the information that says "Allow-new-APs" and 13 access points show up in the list, but only 11 show up under Access Points. They all have lights, cables, and power.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

if you have exactly same settings for all APs and 2 are not coming up then your AP might be dead..or try to console it..or raise Aruba TAC case.
