<p class=MsoNormal>We have a Cisco 3750 PoE switch that is acting very strange.
All of the PoE phones that are currently plugged in work until we unplug them;
if we go to plug them on we do not get any lights on the switch port, the PoE
light on the left-side of the switch flashes amber, and the phone does not do
anything. I can however plug my laptop into the port and everything comes up normal.
Do these switches shut of PoE if they detect a short in the line or there is a
surge on it? If so, is there a way to reset the individual port on the switch?
Any help would be appreciated!<o:p></o:p></p>
