ap epmp 1000 GPS Sync AP random reboot , locup-up gui stop working...

Hi,

    I have  1 EPMP 1000 AP 2.4 Ghz GPS sync i install this summer to test the product. Now it's affect with random reboot , traffic pass but no access to gui or sm cannot register to the ap and i have to reboot it to work. And finally yesterday i have to go to the tower to do a power cycle because  they are completly hang...  ichange the  cable , redo the connector. (metal connector with ground) abd test the cable with a cable test tool) the cable have under 100 feet. The only thing left is the Gigabit POE in it. I wanna know if i can put a normal poe from a non gps epmp 1000 to test. The time i receive  a 802.3af compliant POE i order...  Because now i have 10 clients  that are under control of the AP from Hell... 

Just talk to my cambium seller...

And the problem are the gigabit poe include in the package... They not work well under 0 degree Celcius... And the control unit are in a enclosed box at the bottom of the grain elevator... Im asking myself WTF!
