Re: [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. Josh Luthman

Re: [AFMUG] Problems with Packetflux Powerinjector

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.

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

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. On Tue, May 15, 2018 at 10:20 AM, Josh Luthman

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. On Tue, May 15,

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

Re: [AFMUG] Problems with Packetflux Powerinjector

The UBNT stuff used to be a lot more sensitive than it is. Anything modern should be fine up to 28V on the 24V radios. On Tue, May 15, 2018 at 7:34 AM, Josh Luthman wrote: > Sweet! I'll crank up the power supply another volt. IIRC Ubnt stuff dies > at 26 or 27

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. On Tue, May 15, 2018 at 9:54 AM, Josh Luthman wrote: > Ahh

UBNT stuff will take at least 28 volts without any problem. I run pretty much everything at around 27.4v, and I've never run into any problems with any ubnt stuff. On Tue, May 15, 2018 at 8:34 AM, Josh Luthman wrote: > Sweet! I'll crank up the power supply another

Re: [AFMUG] Problems with Packetflux Powerinjector

Agreed. I expect your issues will go away if you increase voltage. We run all ePMP @ 48VDC. It fixed these random rebooting issues for us. On Sun, May 13, 2018 at 6:37 AM, Forrest Christian (List Account) < li...@packetflux.com> wrote: > 22.93 is too low. Cambium says 23V is the minimum

Re: [AFMUG] Problems with Packetflux Powerinjector

22.93 is too low. Cambium says 23V is the minimum into the radio. See http://community.cambiumnetworks.com/t5/ePMP-Installation/ePMP-PoE-Powering-Primer/td-p/49944 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.

Re: [AFMUG] Problems with Packetflux Powerinjector

So we replaced all 8 surge cards. It's getting 22.95 and 22.93 for the two boxes (to the green terminal). Devices are still rebooting... Epmp never has problems with the same DC supply through the green POE injector, forgot to mention that. Josh Luthman Office: 937-552-2340 Direct:

Funny story if you were using ePMP near the beginning. Some of the first original 5GHz integrated radios had labels marked 56VDC. They were definitely NOT capable of being powered from 48/56V. Somebody screwed up. Yeah. We've run Force180/200 survey setups on a small 12V SLA too. It works,

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

Re: [AFMUG] Problems with Packetflux Powerinjector

The GPS synced radios won't boot at 20v, but the subscriber modules should be able to run at a bit lower voltage (unless the 2.4ghz radios are different, which is possible). With a standard 29v ePMP power supply, there certainly shouldn't be anywhere near that much voltage drop on 100' of cable

They don't boot at 20v. I don't think you'd lose 4v at 100' but I could be wrong. Josh Luthman Office: 937-552-2340 Direct: 937-552-2343 1100 Wayne St Suite 1337 Troy, OH 45373 On Sat, May 5, 2018 at 4:30 PM, Philip Rankin wrote: > I am changing a PMP 100. That is

IIRC the issues are connected if the surge suppressors are in line. I dont recall if the ones we had that were rebooting were resolved with just the port speed or bypassing. Using 48 v makes sure the EPMP doesnt freeze, they will with the 24, and if its long runs the power drop may be an issue too

If you have the old MT surge suppressors with EPMP there was an issue with this and negotiation. I believe current revisions have resolved it. Also, if you are only running 20mhz channels you dont need gigabit connectivity, so you can lock ports to 100mbps to help On Mon, Apr 30, 2018 at 12:16
