Is it harmful to plug a POE energized data source into non-POE NIC card?

Some of our wired ethernet data connections are energized with Power Over Ethernet at 48 volts. But not all of our devices utilize POE.

Is it harmful to plug a device into POE when the device's NIC does not utilize POE? I would like to use the wired ethernet connection for data on a device which does not utilize POE.

POE switches generally check if a device supports POE before sending power to it. If it doesn't, then no power is sent. You should be fine.

1Ok, I believe you. But could you provide a link to some supporting documentation or explain how this is done so I can feel comfortable with the answer? – steampowered – 2012-10-16T22:07:50.093

This page has some information on the 802.3AF standard. The part you're interested in is "detection".
