I am having a problem on the PoE negotiation of Catalyst 3750G-24PS-E and 1130AG Access point. I used straight and cross cable for physical connection since by default the auto mdix per port of the switch is enabled/on. I used CLI, CNA and Web Device Manager on both devices to isolate and troubleshoot the problem but still the PoE negotiation on both devices won't work out. But when I used the access point into other switch (CE500 PoE Switch), the access point is working properly. Does anyone can help me to distinguish what the problem really is? The IOS Version of 3750G switch is 12.2(25) SEE2 and the 1130AG access point IOS Version is 12.3(8)JEA.
