An active device can interrogate a passive device before the interrogated device is powered. This is a protocol that is used in electric vehicle charging for example but now we are off topic...


802.3af is the specification.  It's and IETF spec.  Being able to plug a non-powered device in without damage is a requirement.  http://www.rhyshaden.com/eth_poe.htm

Well...

I just picked up a SG300-10MPP.  You guys are right!  That's a BIG, nasty, power supply.  I understand now why so many were recommending the rack mount 20/24 port version with an internal power supply!  That probably makes sense.
