I guess the biggest question in my mind is whether most WISPs would need a
non-standard 24v or 48v out. At the last Ubiquiti conference they mentioned
that their newest line of AirBeam APs will be running 48v. Obviously their
current line is 24v, as is Trango and Tranzeo. Moto needs the GPS sync signal,
so this wouldn't work for that.
Also, would most people use DC or A/C to power the device? If DC, 24 or
48v?
I talked it over with our electrical engineer, and he says the $450 number
is what it would cost in the three-four quantity we had been discussing. In a
batch of 100, the price would be closer to $250. Is that more appealing?
Thanks!

Hello Kevin,
I'd be interested depending on how many ports you think this device would
have. It seems 12 ports would be a good compromise. If a HUB site requires
more than 12 ports then that site should easily justify another $450 in
equipment, IMO.
Would surge suppression be included similar to whatever basic surge
suppression is found in today's PoE's?
24VDC output would probably be our preference too. Are you saying the DC
input would be adjustable or are you looking for a consensus?
1U shallow depth rack mount is pretty much a requirement for us.
Keep us posted.
Best,
Brad

So... we're most of the way through a mid-span design similar to what people
are outlining here. Right now it's only non-standard POE, though. No 802.3.
Again, we were only going to build three, for our own use. If we sold something
that was:
Remote on/off per port
Auto-ping reboot per port
Dual-power supply, with notification on fail
DC powered, either 12, 24, or 48v
The one we are working on is 24v output only
1u rackmount or small form factor wall mountable
SNMP for reboot, voltage monitoring, input monitoring
We figured if it's a DC device, we can plug it into 110v easily with a
transformer.
If it was $450, would anyone buy them? Actually, what I really need to know
is, would we be able to get rid of 90 of them? We'd have to make a batch of
100, and we could use 10. We'd get them back from the PCB manufacturer mid-May.

I may be off here from the majority, but I don't want a switch. I want to
be able to put these onto router ports as well as switch ports.
I just want a rackmount multiport passive PoE controller, manageable per
port with autoping and redundant power supplies. Is that so much to ask for???
;)

Just put in a 12 port 24V version of this for a UniFi WLAN. Worked
flawlessly.
Powered the UBNT PB5 on one of the ports too.
