Yeah, I'd be perfectly happy with a PDU-like card for -48. Most
definitely a standard/negative return PDU card too.
I'm sure you have lots and lots of ideas and plans for the RackInjector.
I know I've mentioned this and I'm sure you heard me, but a telemetry
card would be nice. 3 switch inputs makes it really easy to monitor the
Traco BMCs. And a shunt input. Plus a voltage input for utility
monitoring. Another thing I like to do is wire up my MikroTik power
through a relay. Basically that just saves a POE port which I tend to
run out of quickly, but using the relay still lets me have remote
power-cycle. Maybe this telemetry card could have a SiteMonitor
expansion bus port? Maybe that could serve as a RackInjector slave shelf
x-connect too? Perhaps a slave RackInjector model without a full
controller in it? I'm sure you've thought of most of this already, just
wanted to throw it out there. I think we're all excited to see what this
thing can become. I want it to be the standard item at any site that I
can fit it.

Yeah, it seems that we didn't disable the airfiber for some reason.
Worse, it was still set to show on the front page. We've fixed that
now.
One of the things on my list is to revisit how to deal with -48VDC.
It tends to be a can of worms, basically because everthing electronic
is generally designed for positive voltages, and dealing with negative
voltages tends to put a wrench in things.
I will say that the rackinjector is designed such that we can build a
card capable of -48VDC and install it without replacing the control
board. I have some ideas on how to do so.....

Like Forrest said, it's a single-port PowerInjector w/o sync. Open
it up to change jumpers for 2-pair or 4-pair GigE injection.
Something that myself, Adam and maybe a couple others have asked
for is a -48 version of something. I'd prefer the 5ch PDU.
Trango's and a handful of other licensed radios are under 2A. Then
there's stuff like Telrad eNBs at 100+ watts. Maybe you could run
3 or 4 of those on a PDU.

You might want to consider renaming it or something, because
it does tend to give the impression that you need something
special for an airFiber.

You're close. The AirFiber came out because I expected
it to need more power than the 4 or 8 port port poe could
handle.
Nowadays it's just a single port version of the gige
powerinjector, complete with internal jumpers, minus the
sync.

I want to say the single-port AF injector came out
before Forrest had the 4/8-port GigE injectors done.
Or maybe even before they were designed. And that's
simply because of the GigE + 4-pair injection scheme.
That was one of the few radios at the time that
required 4 pairs because of the power consumption.
Forrest said the newer relays he's using on the GigE
4/8-port injectors will handle the current fine. The
older orange Omron relays not so much. I've burned up
quite a few of them over the years. Luckily they're
not too difficult to replace.
I'd just use a GigE PowerInjector+Sync these days.
You get 2A per port using 4-pair injection. Plus
solid-state over-current protection. Or the 5ch PDU
and GigE-POE-APCs. There are many good options now.
The RackInjector is gonna be awesome. And I hope to
see the 12-port PowerInjector+Sync later for the
smaller cabinets. Fuses and wiring drives me nuts.

Subject: Re: [AFMUG] Packetflux Airfiber POE
If I remember correctly, the 4 port works fine. I
think the reason for the special one was because
the airFiber 24 draws so much power, but if I
remember right, it was determined later on that the
normal injectors would handle it fine (and I'm
pretty sure I had one running on one at one point).
It certainly wouldn't be an issue with anything
other than the 24ghz airfbers anyhow, since the
others all use a lot less power.
