I haven't tried that.

I don't know if it is coincidence or not, but I just ran a cable test on most of the ports on the first switch. When I did that, POE quit working. Rebooted the switch and POE started working again.

Hi jearhart,

Welcome to NETGEAR's online community!

If you can, please log into the switch managemnet interfaces of both switches side by side,

I did that prior to posting. They were configured exactly the same.

Just after posting, the second switch did the same thing as the first one...no POE output, status showed "Disabled". After rebooting both switches, they both started working normally.

Hello jearheart,

Have you tested the switch when it is not stacked? Try removing it from the stack and see if the PoE will work.

Thanks,

    Hi jearheart,
    
    That's odd. But I'm glad it's working now. Try and monitor it for a few days and please give us an update.
