Installing a new site, when we break power to the switch and re establish, random ports don't turn POE power back on.
WS-12-250-DC on 1.3.9
We have also seen this on a WS-12-250-AC
Ideas?
Thanks
Adam

Re: Some POEs off after power fail
when you say you cut power are you allowing the switch to completely de-power?
If you cut power and re-establish power is less than 5-10 seconds the switch can be left in an unknown electrical state and power up can be erratic and random.

I see nothing wrong with your logs indicating anything.
Saying I have same problem really does not help.
