Hi i am presently a junior network admin a a small college in NY. i am faced with a prob i hope and think that you guys can aid me with some advice or show me the right way to go.. I have a Cisco 3524 switch with inline power we have nodes and VOIP phones running on it but for some reason i cant get it to give the access points power. i did all the correct settings. i have tried three types of AP's on it alrealy none of them worked(dlink,meru AP200 and a cisco aironet 1200). Could it be the version of the IOS version ? it presently has 12.5 enterprise or any other thing? Please Advice.
There are 3 different approaches that you can take.
1.)Upgrade your switch to one that is 802.3AF compliant.
2.)Try to find Access Points that support the non-standard inline power.
3.)Use a third party power injector that is 802.3AF compliant.
Based upon your current needs, and future requirements it might be better to upgrade your switch. 802.3AF is an IEEE standard that is followed all over the networking world, as Cisco created a pre-standard ILP that may not always work on newer devices. Your current switch may not be able to everything that supports Power over Ethernet. I don't know off the top of my head of any Access Points that will work for you.
Hope this helps,
