I have three ERPoe5 units that are driving me crazy. On two of the units (purchased at different times), the unit will run just fine for a variable amount of time, then lock up hard. When I inspect the unit, the poe LEDs are on, but the unit is unresponsive and there may or may not be poe power to radios. When it is in the mode, it is unresponsive, even if attached directly to a port. (I do not have a serial port on the laptop and have not tried the console during this time. I have set the remote logging to debug and nothing shows up in the remote logs. To recover, the power must be removed. The process then starts over. The time to lockup seems to vary. One unit started out at a week between failures and now is at an hour or two before failure. The second unit is under an hour between failures. Both units started with v1.6.7 and were then upgraded to v1.7.0 and now v1.8.0 and it still occurs.
I also have a third unit with similar issues, except this one will randomly start working again. The other two lock up hard. This one locks up and then after a couple of hours magically starts working again. Then locks up again and so on.
All of these units are installed at a remote location that takes over an hour to get too. What a pain.
Any ideas on what is going on? Seems like a high rate of failure if it's just bad hardware.
