Thanks Forest. If you need any testing done by me let me know. The sites is a little far away but I can probably get a tech to stop out and plug different cables in for me while I monitor remote.
Just to make things a little more complicated I do have a PowerInjector and a SyncInjector at the original trouble site. Being fed from a Sync Box Jr. First to the PowerInjector then to the SyncInjector. Also the SyncInjector today that did work is the old enough version ( sorry didn’t get the version) but it’s the old enough one that says only 24 volts on it but it can do 48 volts. Its from that transition stage when you were shipping with the older label still.

Same circuit, add jumpers. There are of course some layout differences but electrically they're identical. This is exactly the type of weird crap we see with the ePMP, that makes no sense at all. I'm not recommending this, but it wouldn't surprise me if you swapped that powerinjector for the syncinjector and it worked perfectly. I also wouldn't be surprised if it didn't. I'm traveling the next couple of days, when I get back early next week I'll see if I can squeeze out a few hours to get an ePMP on the bench again and see if anything else leaps out at me as far as why this might be occuring...

Power injector is in fact Gig and no jumpers were changed running on 48 volts. We are running through MTOW suppression REVD however we have bypassed the suppression to see if it makes a difference. It did not. I have also bypassed the suppression and used a 2 foot non shielded patch to another AP laying on the desk inside the building with no puck installed. It did not receive sync over the CMM3. Last piece of equipment is a SyncBox Junior Basic for the sync. Firmware is 2.6.2.1 I am at another site today where we did not have our ePMP APs on packetflux for power or sync. They were running on OEM power and GPS pucks. I have a 450i running at this site on a Gigabit SyncInjector 48 volt powering it. It has a SyncPipe Basic for its GPS. Since there is only one 450i on the unit I put one of the 2.4 ePMP APs on it and set it to CMM3. It received sync in under 2 minutes after being physically powered off. Faster on reboot. Firmware is 2.6.2.1. MTOW suppression is REV A1. This site is at about 180 feet of wire per ap. I was really hoping it would not work here and I could start looking at reasons that I had created to cause the issue but no dice. Is it possible it’s a SyncBox Jr or PowerInjector difference causing this? I would assume others are using the newer platforms with ePMP and CMM3. Is there any specific grounding requirements for the PowerInjectors that were not on the SynInjectors?

My favorite story was of a customer who couldn't make ePMP work with a powerinjector. We sent replacement equipment and they had a full tower of spares. Swapped the entire tower one by one piece. Still wouldn't work. Everything looks fine, lights blinking, etc.... They took the original equipment back to the shop. Hooked it up on the bench, worked perfectly. Mind you this is exactly the gear on the tower which didn't work - no configuration changes, etc, other than using patch cables to make it work. Then they took that equipment back out to the tower, swapped it back in so it was identical to the original and amazingly it all works perfectly. As far as I know it is still working just fine. I've had exactly one time on the bench that I couldn't get an ePMP to sync up. Could reboot it, swapped cables, etc, still no work. Grabbed the cable I use to hook a cable up to the scope.... Plug it in, ePMP immediately starts working. "Fine, it's something which this cable changes". Put the original cable back in place, ePMP *still* receiving sync fine. No matter what I try I can't get it to fail again. So much for being able to reproduce it. Just out of curiosity, did any of the Jumpers in the PowerInjector+Sync get changed? Is this a gigabit powerinjector? -forrest On Tue, Mar 28, 2017 at 9:23 PM, Brandon Yuchasz <[email protected]> wrote: That’s George and Josh, We are running 2.6.2.1.

Receiving sync just fine. 48VDC supply on PowerA. New out of the box, no jumper changes. Plugged in a 5GHz GPS radio running 3.2.2. Puck disconnected, radio laying face down on the table. Set sync source to CMM3. Saved and power-cycled. CMM sync status is down. On-board GPS status shows n/a lat, long and height. 2 sats visible, 0 tracked. CMM sync finally comes up after 3 minutes and 15 seconds or so. If the radio comes up with a good on-board GPS lock, it will receive CMM sync pretty fast. If I simply reboot the radio, CMM sync is up a few seconds after it lets me log in. A power-cycle resets the on-board GPS (obviously), but a soft reboot does not. I remember someone from Cambium explained some of this several months ago. Maybe Sriram or Dan Sullivan? They use the on-board GPS for timing, regardless if a CMM is in use or not, but if it is, then the sync-over-power pulse is fed into the on-board GPS. Whereas with Canopy, this is all done in the FPGA. So I suppose if the on-board GPS locks up, then perhaps CMM sync won't work either. I don't really know. I don't know what to tell you other than ask Cambium for help. On 3/28/2017 4:07 PM, Brandon Yuchasz wrote: I figured someone had to be doing it. Its not that big of deal until we have a failure on one of the pucks in bad weather and then we will want to drop back to the packetflux. I can’t figure out why the 450i works fine and the epmp wont. Its seems like they should be the same. We started on 24 volts went to 29.5 volts and then to 48 volts just to match the 450i stuff. No difference.

We have our sites with the onboard GPS puck as the primary GPS and just recently started powering the newest sites with Packetflux in order to provide a secondary GPS signal. At one site we has an AP that the puck GPS was blocked during install and would not receive sync so we turned on CMM3 and never were able to get GPS. Eventually we just did a climb and moved the puck and its receiving GPS now. Last week when installing a new site I decided to try GPS through the packetflux again and was not able to receive it. If I swap one of the cables from a 450i into the same port on the packetflux we get GPS no problem on the 450i AP but no joy on the epmp. I even went out and grabbed an extra AP off the truck plugged it in with a 2 foot none shielded Ethernet to the packetflux and still no GPS on CMM3. We are using power injector plus at the newest sites. No changes using them out of the box on 48 volts and like I mentioned they provide GPS just fine to the450i. So I am wondering if anyone is running this setup successfully of if we are all just using the puck. Thanks, Brandon -- Forrest Christian CEO, PacketFlux Technologies, Inc.
