Hi, list!
We have actually 4 BaseStation (but in the future we will buy at least other 2). Now want my Boss to buy a PoE-Switch at which we connect all BaseStation. This Switch has to supply power, too.
Now, I'm not sure (I don't know PoE in detail) if I can use every PoE-Switch. I searched in Internet and I found a Netgear FS108P. It's cheap and it will be enough for us. Can I use it with our BaseStation or have I to use the power supplier of the BaseStations, too?
Thanks a lot for your answers!

No you can't. The nanoBTS are not fully PoE compliant. For example they didn't work with my Netgear GS724TP or GS748TP.

The netgear FS108P is a switch that's known to work with them. I use it myself.

I believe the nanoBTS 1) draw more power than the standard permits 2) don't do the proper handshaking but simply draw power without negotiating it

it works for me, too. but only for two nanoBTS, as soon as I connect the third, the overpower LED of the switch lights up.

Aha, thanks for your answer.
Do someone knows other PoE-Switches that can be used with 3 or 4 nanoBTS? I will need at least to connect 3 nanoBTS...
Thanks a lot! Luca

I just found these switches:
- DES-1008PA 8-Port 10/100 Desktop Switch with 4 PoE Ports - LANCOM ES-1108P
The first has a power supply of 48V DC/1.45A, then I **THINK**, I should connect up to 4 nanoBTS (power consumption of a nanoBTS: 0.3A). The second give for every PoE-ports 15,4 W, with 48V supply it is ~0.320A.
Do you think I can use one of these Switches to connect 3 or 4 nanoBTS?
Thanks a lot!

As NETZING are an official ip.access Customer, you should have access to the data sheet that specifies the maximum power consumption of each BTS unit. Based on this you can then search for available switches that provide at least this amount of power on each port.

Maybe you should ask ipaccess?
