I would check the rev of the GIGE-APC card. Older cards did not play well with ePMP sync over power.

I will answer your questions below but won’t be able to try the breaking of the shielded cable until I visit the site again. It could be a couple weeks before I am there again. Here is the info: We were running 24 volts ( although as you pointed out I took it up to 48 volts by putting it in place of the 450i) I did not have a 30 volt on the truck so put the 24 volt in until I could replace it. Cable length is less than 200 feet probably closer to 180 feet. It was about 40 degrees F when I was trying to do this and sunny. This is a gigabit sync injector . The 450i that I plugged it in place of was/ is being fed by a PowerInjector Plus. ( have not touched the jumpers) These are being feed through a MTOW ( newest version rack mount APC style ) suppression. I could look it up for model but I think you know what I mean. One thing worth mentioning is my MicroTik RB1100 was having issues negotiation Gig connections on the ePMP APs and the 450i APs. I ended up letting it negotiate 100mb instead. The ePMP backhauls are running auto negotiated gig no problem but are on Cambium OEM POE instead of a packetflux for power. Same suppression in place and same shielded cables. Let me know your thoughts. I am happy to try breaking the shielding connection and report back but like I said it could be a few weeks.

(UPDATE) It sounds like you covered all of your bases, especially since you plugged the ePMP radio in where the 450i was and it didn't work. So some of the ones below don't seem to apply: What voltage are you running the injector at? How much cable length are you running? The ePMP radios reallly are picky about 24V and long cable runs, especially when it's cold out. This is a gigabit syncinjector, right? If so, I won't ask you if you changed any jumpers in the units. I do have one very odd request: If these are shielded cables running up the tower, can you somehow break the shield on the bottom end? A short unshielded pigtail to a keystone jack often works. If you have a surge protector at the bottom, try inserting this either between the injector and the surge, and alternatively between the surge and the cable up the tower. I've had 1-2 reports that reterminating the cables with unshielded ends at the bottom causes otherwise unsyncable ePMP radios to suddenly start receiving sync. -forrest On Mon, Feb 20, 2017 at 9:14 PM, Brandon Yuchasz <[email protected]> wrote: So to update this previous post. Went to the site and confirmed that yes we were getting the blinking sync light on the SyncInjector feeding the ePMP APs, I logged into the AP that did not have GPS and set it to use the CMM3. Rebooted and no joy still no GPS. Frustrated I ended up unplugging the cable feeing one of my 450iAPs that was receiving sync from the PowerInjector Plus and plugged the ePMP APs cable into it. Still no joy no GPS after waiting several minutes. I am not sure how my 450i APs can be receiving GPS from the unit but the ePMP doesn’t from the same feed. I ended up doing a climb and relocated the antenna for the onboard GPS in the ePMP. It now has GPS from the onboard unit but it would still be nice to have the secondary over power working. Any thoughts I am all ears.

The ePMP1000 GPS radios will take 802.3af or Canopy -4/5 +7/8 at either 24 or 48 volts. Running them at 48-56 as others have pointed out several times in the past is better with the cold startup and whatnot. The ePMP Sync radios don't do AutoSync like Canopy. You have to select internal (generate in Canopy terms), GPS (on-board), CMM3 or CMM4 for Sync Source on the Config > Radio page. You want to select CMM3 when using a PacketFlux injector.
