I have a Cisco 3750PoE-48 network at all of my stores. Sometimes a ZF7982 will stop communicating with my ZD3000 causing service outages at that location. I have found only 2 things to fix this particular problem; either move the wap to another port and configure the port or reboot the switch for the wap to come back up. Anyone having this issue?
The common workaround, if you have enough ports, is just to not connect two APs in adjacent ports, either side by side or above/below each other, so only 2 APs draw power from a 4 port block of switch ports, often powered by a single tranceiver each.
