Odd Cisco PoE Switch Reset

This is an odd situation to me. Eight months ago a user disconnected their VoIP deskset from the switch at the wall drop. This caused ‘all of the phones to reset’. I thought this was impossible, but spent a couple of hours trying to duplicate this. No luck.

Today I got a call( via cell phone) that all of the VoIP phones on a different subnet just reset. At the same time I received a notification from the network monitor that a wireless access (also PoE) was offline. I found that someone had unplugged the WAP from the drop.

Is it possible that unplugging a device from a PoE switch can reset the switch causing all of the devices on that switch to reset?
