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.

I've been doing 24v since day one and it's gone through a couple of winters now. Thing is that we don't reboot when it's 5* and the batteries are all inside on the ground. Chuck...would epmp have problems here rebooting/not powering for a few minutes with bad SS cards?

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 On Mon, Apr 30, 2018 at 12:42 PM, Josh Luthman <[email protected]> wrote: No ethernet problems - it's POWER.

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 PM, Josh Luthman <[email protected]> wrote: I've got two of these with problems: http://store.packetflux.com/powerinjector-plus-sync-gigabit-version/ However one of these gives me no problems: http://store.packetflux.com/sitemonitor-4-channel-gigabit-poe-injector-controller/ I have a 24vdc plant going up the tower. In the box it feeds these three Packetflux units. The 4 channel POE injector has given me 0 problems. I've got Cambium ePMP on the PowerInjector and it has been randomly? rebooting units for several months. Yesterday one of the ports just decided to turn off for 20 minutes and come right back. We've replaced the line & radio to make sure it's the box, but all signs point to it. Has anyone else seen this or am I lucky in getting the only two units with power problems on them? AFAIK sync has been just as reliable as the power through them. Josh Luthman Office: 937-552-2340 Direct: 937-552-2343 1100 Wayne St Suite 1337 Troy, OH 45373
