Hi !
I want to connect hAP ac lite routers with a twisted pair via POE ports.
Connection scheme: hAP ac + hAP ac lite + hAP ac lite + hAP ac lite (CAPsMAN).
Will there be enough power from one hAP ac router for the entire serial link hAP ac lite or will an additional power supply be necessary?
Please tell me ))
In the network I found here is a scheme, but for my purpose mAP2 n is not suitable
I wouldn’t expect this to work.
Each daisy chain has a loss of power so your first 2 will probably boot then throw an error leaving all of your other devices limp.
hAP ac lite can work with voltage up to 30V. Maximum PoE out current can be 500mA and declared power consumption of single unit is 7W. If you find 28V power supply, then you might power 3 hAP ac lite units daisy chained. But: nothing is written about max PoE in current, I’d assume 500mA applies here as well, which means that you can not power all 3 units through PoE injector but rather through power jack of the left-most unit.
hAP ac (non-light) specs don’t say anything about max PoE out current, but again I’d assume 500mA.
Seems like it’s quite possible to have two units daisy-chained (even using PoE injector), but not more. If you placed PoE injectors between first and second 'lite, you could power all 4 from single point. With slight variation of used ethernet ports for connection between units to allow power flow in the right direction (which might be left 
).
I can confirm this, we have daisy chained two RB951Ui-2HnD and two hAP in many places. On startup they are consuming from power unit about 150mA each, so, perhaps 3 units chained are acceptable, we don’t experiment on this.
The PoE output ports are also only usually rated to ~500ma. There have been a few threads about RB2011 exceeding that and then the port going completely dead with no PoE output at all. Really wouldn’t want you to damage your kit “trying” this.
