Today I tried to connect one from my purchase from ebay, ZF7351 to ZD1100. This AP not support POE, but is dual band. After cofigure ZD and connect with AP I start Inssider and see my SSID in 2,4 and 5 Ghz both. I connect my iPad to AP at 5 Ghz, and it work, I connect my notebook at 2,4 Ghz and it work too. After some experiment with various devices I find this AP concurrent dual band, but according to the ruckus support site this is 2,4 Ghz AP. It happens?
ZF7351 is a sub model of ZF7352 with the only difference is that it just have one ethernet port. Officially It is also a single band device and looks like that you got a ZF7372 feature AP with Label of ZF7351.
It should NOT happen however my guess is that something went wrong in the factory. Nothing to worry about as this AP is also End of life.
