Hello Friends. Could somebody tell me:

1. I want connect 4011 using RBGPOE what shipped with cAP ac and as I know, cAP ac have compatibility with 802.3af/at, RBGPOE have 1gbps port and if I plug in cAP with this PoE adapter + PSU cAP ac, I really can take 1gbps line data with 4011 and cAP? Because Passive PoE using 2 pair of UTP 5e cat cable and maximim speed on Passive Poe is 100mbps, all is right?

2. If I will send PoE from 4011 10th port to cAP ac, PoE will be just Passive and maximum line data speed be 100mbps, right?

Thanks.

1) If bot devices have 1G ethernet, both work at 1G.
Do not make suppositions, if is a gigabit poe, still a gigabit poe, you knowledge about cable pairs do not influence how the tings really works.

2) 10th port work on 100M because the port is 100M, and not because that port provide poe out.

Thx. I've try belive (etc "The Matrix")

4011 have all 10p = 1gbps, but you can get just 100mbps with 2 pair UTP cable, because Passive PoE take 2 pair for power + and power - and I am interest, really cAP ac will working on 802.3af/at with injector, if it's that, totally speed will 1000mbit per sec.

On detail, but I'm not english and is hard to explain, on gigabit all pairs are used for transmit signals,
but ALSO at the same time voltage is provided at blue+ and brown- pairs.
This added voltage do not destroy signals (and vice-cersa) for various electric reason better described on dedicated sites.

Not destroy? As I know you can't use Passive PoE and get 1gbit without special injector, because it have transform your voltage and yes you can get 1gbit.

rextended What you think about: rb4011igs 5hacq2hnd-in really so warm up and freeze? I am order this device, now wait, I have 500mbit my ISP provider and I want belive that will good wifi signal + cAP ac in other room.

Ok, so thx! Let's feed our cats

Essential difference between passive PoE and 802.3 af/at/... is not in how wire pairs are used but how PSU and PD communicate the power details. In both cases power can be transferred over wires used for data at the same time and also passive PoE (if made for gigabit) includes appropriate circuitry. Injector RBGPOE has it (whereas older RBPOE didn't have it) and all routers/switches providing PoE on gigabit ports have it (that includes RB4011). And similar circuitry is present on gigabit ports used for PoE in.

mkx, thx )

I want belive that will good wifi signal + cAP ac in other room.

You definitely will not see 500 mbps on wifi with CAP ac and in another room. I would recommend getting a 4011 without wifi. And for wifi use a device of another vendor's standard ax
