You are right, the CTM2 _is_ pretty damn close but:
They are very pricey They only have 8 ports The AC power supplies are built into the unit and cannot be replaced without taking the device out of service... I guess DC power is a solution to this It has unwanted (by me) timing features Peter Kranz <http://www.unwiredltd.com/> www.UnwiredLtd.com Desk: 510-868-1614 x100 Mobile: 510-207-0000 <mailto:[email protected]> [email protected] From: Af [mailto:[email protected]] On Behalf Of Josh Baird Sent: Tuesday, March 01, 2016 11:13 AM To: [email protected] Subject: Re: [AFMUG] Mid-Span multi-voltage power injector with redundant power..

Nice to have (but not a deal killer) - Multi-voltage capable... 48V UPOE for Siklus, 24V for UBNT and Cambium What I don’t want - A built in switch, I already have fancy ass switches, why do I need another switch in the way, probably with crappy features and poor buffers.

The power bus can be done. But price will jump quite a bit. I have worked up a design for this but always backed off due to the cost. One of the problems is that there is a connector I need that cannot be put on the circuit board by machine. Lots of hand work. So if I build it will anyone come?

I like the idea, but no solid state fusing, no power buss, tons of wiring, it’s a mess to deploy this when you have over 20 APs on a single tower..
