Problem c5c the link is disconnected


good morning.

I have a problem with some c5c, I have 2 c5c links at 30 km, the 2 have cable cat6, their original poe of 54v and are landed.

since a few days ago one of the links lost power to the point of disconnecting, yesterday I put another new c5c and re-linked, the one that loses power is the cpe.


Did you replace the original power supply when you replaced the C5c?

What caused the other one to loose power?

Will the original C5c boot off of another power supply?

You might want to check the cable as well to see if there are any breaks, one time I had a customer weed wack his cable and then called us with weird intermittent issues. I eventually gave up trying to diagnose it remotely and only found the issue because I dropped a tool off of the roof. Two days of diagnostics and three hours of replacing and trying out various antennas on a roof taught me a very valuable lesson. To quote my cousin who does networking for the Air Force “always check Layer 1 first.”
