WS-10-250AC power mis-reporting?

Thu Aug 16, 2018 2:16 pm

Here's something odd after upgrading to 1.5.0 on one of our switches. Everything is working fine, but the power being used as reported by each port is being miscalculated somehow. This is one of our older Netonix products, and some ports are down due to water infiltration. The board is Revision E, which matches a lot of our WS-8-250AC's.

All of the devices showing ~40W are Ubiquiti Rocket units. Also one AF5X that is on 24V on Port 1. Port 2 is another AF5X on 24V High. But it's only using 1.1W according to this screenshot, yet everything else is in the 40W range. Something seems way off here.

Ideas?

This is probably not a miscalculation?

I am guessing current sensor damage but could be wrong, maybe something is messed up, try a reboot.

If no love from reboot open it up and inspect the current sensors, usually current sensor damage is very obvious.

Could be damage indeed. That location had a terrible storm a couple of weeks ago, and we lost one of the AF5X units. Are the current sensors a typical tombstone transformer, or something else? Will try a reboot though and report back.
