If I turn off PoE for a few minutes and then turn it back on the radio will come back online and work from a few minutes to a few hours before disconnecting again.
After this last disconnection I was looking at the radio and it kept switching between a "DOWN" state and a "100M-F" state (shown below) . During this time I was NOT able to access the radio as the state change would change very quickly and never stay on 100M-F for more than a second.
first state
second state
It's a fairly long run but nothing has changed on it anytime recently that should have caused this and the wires check out okay.
After turning PoE off and back on the link will come back up and show the 1G link with flow control active
Then it will go to the standard 1G and be fine until again it just disconnects
When it's up everything looks generally pretty good
It can't be the reason, but it feels like the radio freaks out for a few and then after power cycling it's okay until the next time - randomly in a few minutes or few hours. I'm just looking for ideas here from someone who may have seen something similar
