I have a SG220 50P switch that lost all POE power to all ports.
We have performed a reboot and and power rest on the switch with no results.
POE was running VOIP phones. We had sporadic POE issue over the last few months.
The Port Management POE properties show
Nominal Power 375W
Consumed Power 0W
All port have POE Management "enabled"
All port show POE status "off"
A replacement switch was install and the Database copied over to the new switch
Everything now works.
Any body having POE problems on this type of switch..
