T710 can't be powered on with 802.3at compatible switch

Question

I flashed the AP to unleashed 200.8 for now. I tried two switches, both support 802.3at, one is ubnt es-8-150W , the other is 
                        S5720I-12X-PWH-SI-DC.None of them can power it up. Now I have to use a POE injector for it. Does any one use ubnt or Huawei switch to power it on?

No problem from my side

Only issue if ap reports that no enough power - switch power mode to 802.11at directly on ap. Group policy or auto doesn't work with my netgear and zyxel switch
