At last I got mAP lite. And it is really the smallest AP a ever see! But I was surprised when found that power consumption is up to 3,5W. And original power supplier is 2000mA.
Initially I wanted to use 4 mAP lite with Mikrotik PowerBOX RB750P, but the PowerBOX is support no more then 1A per port and 2A in total. And it looks like powerbox becomes useless
Anybody have good experience with PoE and what cheap PoE supplier (multiport injector or switch) you can suggest?
