他可以为 UAP-AC 进行 POE供电吗？ 感觉很少有交换机 支持 IEEE802.3at 的。
UAP-AC 在被 POE 供电可能一些问题，因此 POE+ 是必须的（结论源自 以下）。
我这几天在 ubnt 的英文 论坛里查询了一番，发现了一个很有用的 帖子，由于论坛需要审核链接，我就把有用的回帖部分 发出来，以供大家查阅。
After testing this for a few weeks I think we can safely say the problem was not with the software. I ran the 3.x software for less than tow days and experienced network drops again. As agreed I inserted the Ubiquty power injector to power the access point.
It has been two to three weeks now and have not had the access point drop anything again. From this I am to deduce that the power source being the problem. I have not seen any logs in the PoE swtich that showed any power drop or issues. Guess I will have to replace that.
Thank you Mike!
