subject:"\[AFMUG\] Problems with Packetflux Powerinjector"

It's just weird it has no problems with 8 radios for 2 years and then in
the last 6 months it starts acting up with only half that many.

I was thinking more like go from 24 to 25-26 volts.  That extra volt or two
might solve all my problems and be a minor change to anything.

Temperatures in both radio and power source which can be adversely 
swayed by external temperatures

If the voltage is too low, why would they randomly reboot maybe once

The runs are well under 100m.  24vdc feeds the NEMA enclosure, then we 
have maybe 25 feet of cat5 to APs.

I would think it's no more than 1 volt loss from my 24v source to the 
AP, but I have not verified this.  I know it's 24v at the green 
terminal block to the POE injector/Gigabit Sync injector.

The other item is what has been mentioned, if you have too low of
a voltage into the PowerInjector, the ePMP's will reboot.   This
is especially true in cold weather since the units seem to draw
more even after startup.   You need around at least 26V on the
input of the power injector, if not a bit more, for an ePMP to run
correctly on a full 100m of cable.  You could probably get away
with a bit lower voltage on shorter runs.

The 10/100 injector doesn't drop quite as many volts due to it
being a switch closure instead of a semiconductor junction, so you
might be right on the edge of what is acceptable.

BTW, too low of voltage will also cause 'trips', as when the
voltage drops below acceptable ranges for the ePMP, the ePMP power
supply circuit tries to pull more and more power from the CAT5
cable, eventually causing what looks like a brief short circuit
just before it shuts down.

Yeah, older Mikrotiks are the only thing that I can remember ever running
into problems with at that voltage... but as you said, they belong in the

I set the no-load float voltage at 27.6 for the AD-155B's. Got some
older RocketM's on 40-80 feet of cable and they've been fine.

The only real issue I've had is gear at the bottom not liking the higher
voltage. Mostly older RB493's, which I replaced and threw in the round
filing cabinet.

If you're doing say 27.4v at the bottom and 100' of two pair 24
gauge, it's more like 26.83v at the top. I'm not losing that ~0.6v.

You need to subtract a bit of loss inside the
injector, and then a bit more for cabling. Plus
a bit more for everything else.

For verification, I took my bench ePMP and hooked
it up to my power supply - it doesn't even turn on
until 22.5V at the radio. I'm sure other copies
are probably higher or lower. And I'm sure it
changes with internal temperature of the radio.

One big difference between the PoE Injector and
the SyncInjector is that the syncinjector uses
semiconductor switches which generally have a bit
more voltage drop than a relay. The tradeoff is
that the semiconductor switches can switch far
more power than the relays can and can switch
quickly enough to do sync over power.

Re: [AFMUG] Problems with Packetflux Powerinjector

One other option is to put 48VDC in at the bottom of the coax, and then use
a DC-DC converter at the top.   I'm particularly fond of the meanwell
rsd series, specifically the meanwell RSD-150C-24 should do just fine.
Assuming you don't have more than 150W of radios up top.   If you need
less/more there are smaller/larger options available.

Re: [AFMUG] Problems with Packetflux Powerinjector

Yeah, in that case you're not going to have much drop. The only reason I
shoot for 27.4v is to match the float voltage on batteries - if you don't
have to deal with that, just set it to 26v, or so and you won't need to
worry about anything.

Re: [AFMUG] Problems with Packetflux Powerinjector

You don't lose any voltage until the radios start drawing power, so it
generally isn't 100% safe to boost it beyond what the radios are rated
for.  I'd set the voltage at the bottom to the absolute maximum you know
the radios are fine with.  Then it can only go down from there.

Re: [AFMUG] Problems with Packetflux Powerinjector

Reason I ask is if at the bottom I believe it's 24v and the top it's 24v.
I'm using that heavy duty coax (inch and a half?) up the tower for my DC.
I think the center conductor was 8mm.

If you're doing say 27.4v at the bottom and 100' of two pair 24 gauge, it's
more like 26.83v at the top.  I'm not losing that ~0.6v.

I really don't want to fry anything and start replacing radios :(

 You need to subtract a bit of loss inside the injector, and then a bit
 more for cabling.   Plus a bit more for everything else.

 For verification, I took my bench ePMP and hooked it up to my power
 supply - it doesn't even turn on until 22.5V at the radio.   I'm sure other
 copies are probably higher or lower.   And I'm sure it changes with
 internal temperature of the radio.

 One big difference between the PoE Injector and the SyncInjector is
 that the syncinjector uses semiconductor switches which generally have a
 bit more voltage drop than a relay.  The tradeoff is that the semiconductor
 switches can switch far more power than the relays can and can switch
 quickly enough to do sync over power.

Re: [AFMUG] Problems with Packetflux Powerinjector

27.4v is at the power supply, so where there's 100' or so of cable, voltage
is going to be quite a bit lower at the radio, but we have some sites where
there's only a few feet of cable and it works fine.

 You need to subtract a bit of loss inside the injector, and then a bit
 more for cabling.   Plus a bit more for everything else.

 For verification, I took my bench ePMP and hooked it up to my power
 supply - it doesn't even turn on until 22.5V at the radio.   I'm sure other
 copies are probably higher or lower.   And I'm sure it changes with
 internal temperature of the radio.

 One big difference between the PoE Injector and the SyncInjector is
 that the syncinjector uses semiconductor switches which generally have a
 bit more voltage drop than a relay.  The tradeoff is that the semiconductor
 switches can switch far more power than the relays can and can switch
 quickly enough to do sync over power.

22.93 is too low.   Cambium says 23V is the minimum into the radio.  See

 What is the dimensions for one of these units?

Thanks

On 04/30/2018 05:00 PM, Forrest Christian (List Account) wrote:
If you have a base unit attached to these, you should look at the 
event counters on the tripped line in the binary/boolean tab to 
determine if the device is detecting an overcurrent event.    If it's 
seeing an overcurrent trip, then yes, check the surge suppressors.


The other item is what has been mentioned, if you have too low of a 
voltage into the PowerInjector, the ePMP's will reboot.   This is 
especially true in cold weather since the units seem to draw more even 
after startup.   You need around at least 26V on the input of the 
power injector, if not a bit more, for an ePMP to run correctly on a 
full 100m of cable. You could probably get away with a bit lower 
voltage on shorter runs.


The 10/100 injector doesn't drop quite as many volts due to it being a 
switch closure instead of a semiconductor junction, so you might be 
right on the edge of what is acceptable.


BTW, too low of voltage will also cause 'trips', as when the voltage 
drops below acceptable ranges for the ePMP, the ePMP power supply 
circuit tries to pull more and more power from the CAT5 cable, 
eventually causing what looks like a brief short circuit just before 
it shuts down.

I've got Cambium ePMP on the PowerInjector and it has been

Yeah. We've run Force180/200 survey setups on a small 12V SLA too. It

Still works. However, I recall the regulator is very inefficient down

I had a portable 12V battery that I would use for site surveys with the 
old PMP100. I'm pretty sure they would function in the 8-10V region.


I know nothing about the ePMP radios. Trust George.

2018-05-06 Thread George Skorup

We never deployed any 2.4GHz ePMP, but I believe all of the original 
2.4GHz ePMP 1k's (integrated, connectorized, connectorized GPS) and the 
5GHz connectorized GPS radio are 802.3af. The voltage regulator will 
only tolerate 20-60VDC. That's when the flash (or RAM?) heater issue 
came up in the winter for a lot of folks. Too much current (and 
compounding voltage drop) with the heater on down around 21-22 volts. 
The fix was to use a 29.5VDC supply.

Original 5GHz integrated and connectorized are 14-30VDC, -4/5 +7/8 only.

2.4 and 5GHz Force180/200 radios moved to the bridge rectifier polarity 
agnostic setup, however still only 14-30VDC. Same now with the 450b SMs.

I have some 5GHz 1k GPS radios powered from a RSD150C-24 and 100-150' 
cables for about a year and a half now and they've been working fine. 
We're getting ready to replace those with PTP550s. So now of course I 
have to re-wire a bunch of stuff for 48VDC.

Also have an AD-155B at a site. 27.6VDC float voltage to the gear. Got 
an old Rev E SyncPipe on top and it shows Vin: 26.1v. That's 200 feet of 
cable. 1.5v drop. Those ePMP GPs radios under load are probably still 
seeing 25+ volts. Off of an RSD, I'd guess 22 volts which would be 
cutting it close. The nice thing is, those can easily be moved to 48VDC. 
I wish Cambium did this with the 450i, but meh I guess.

 I would think it's no more than 1 volt loss from my 24v source to the

 The other item is what has been mentioned, if you have too low of a
 voltage into the PowerInjector, the ePMP's will reboot.   This is
 especially true in cold weather since the units seem to draw more even
 after startup.   You need around at least 26V on the input of the power
 injector, if not a bit more, for an ePMP to run correctly on a full 100m of
 cable.  You could probably get away with a bit lower voltage on shorter
 runs.

 The 10/100 injector doesn't drop quite as many volts due to it being a
 switch closure instead of a semiconductor junction, so you might be right
 on the edge of what is acceptable.

 BTW, too low of voltage will also cause 'trips', as when the voltage
 drops below acceptable ranges for the ePMP, the ePMP power supply circuit
 tries to pull more and more power from the CAT5 cable, eventually causing
 what looks like a brief short circuit just before it shuts down.

Re: [AFMUG] Problems with Packetflux Powerinjector

2018-05-02 Thread George Skorup

I'm running some 1k GPS radios from RSD-150C-24's which always put out 
24.0VDC. Injectors all at the bottom, 100-200 feet of cable and they 
work fine.

The only real problem I've had is getting them to maintain gigabit links 
without errors. They'll either run fine with 50-100 CRC/FCS errors a 
day. Or I'll get lots more FCS errors and the links will drop a couple 
times a day. Some of them will eventually fall back to 100Mbps. Take the 
GigE-APCs out and they run gigabit with no errors.

Chuck sent me some modified CAT6-APCs to try. I just haven't had time to 
dive into it yet. Hopefully next week when we replace a couple of those 
1k GPS radios with PTP550s.

have maybe 25 feet of cat5 to APs.

I would think it's no more than 1 volt loss from my 24v source to the 
AP, but I have not verified this.  I know it's 24v at the green 
terminal block to the POE injector/Gigabit Sync injector.

with a bit lower voltage on shorter runs.

The 10/100 injector doesn't drop quite as many volts due to it
being a switch closure instead of a semiconductor junction, so you
might be right on the edge of what is acceptable.

BTW, too low of voltage will also cause 'trips', as when the
voltage drops below acceptable ranges for the ePMP, the ePMP power
supply circuit tries to pull more and more power from the CAT5
cable, eventually causing what looks like a brief short circuit
just before it shuts down.

There is - here are the counters: https://imgur.com/a/FdVP9IF
Note that bb5/6/7 have been losing power frequently too.

If the voltage is too low, why would they randomly reboot maybe once or
twice a week and then be fine for months at a time?

The runs are well under 100m.  24vdc feeds the NEMA enclosure, then we have
maybe 25 feet of cat5 to APs.

Re: [AFMUG] Problems with Packetflux Powerinjector

If a surge suppressor gets wounded it can cause all kinds of problems.  As a 
sacrificial element, it is sometimes not clear if they have taken too many 
hits.  Best way to test is just bypass and see what happens.
