Hey guys, I have 4 of these switches.
One switch works as intended - Boots, Accepts configuration, Provides POE. However, after about 3 days the switch stops responding. Won't recognize console USB cable inserted, TX/RX lights stay lit when cables unplugged. Works again after power cycle.
The other three will boot, accept configuration, and will uplink to the network. However they won't provide power to connected POE devices. I've ruled out configuration issue, as I have cloned the configuration from the 'working' switch to all 3 of these non-working switches.
I'm at a loss for where to look, since the 802.1at POE standard has a couple different ways a switch can discover and supply power to a POE-capable client device.
Does anyone have access to a schematic or block diagram for ANY recent Cisco POE-enabled switch?
