Switch w/no power (PoE still working??)
Posted on 2013-06-27
So we had two enterasys switches "lose power" last night. They were still plugged into the UPS when we came in this morning, but were off. When I replugged them into the same UPS, they came back up.
The weird thing was, the people on those switches couldn't get a connection, but it was displaying the "limited or no connectivity," and our IP phones (which work off PoE) were powered up to a DHCP display, instead of displaying the persons name, ext., etc. But they must've been getting SOME power from the switch, which had no lights on it lit up at all. everything on the switch was completely off.
any ideas on what happened or how this is possible?
