Along these same lines, I noticed that Cisco has some 10/100/1000 blades
with PoE. I thought that 1000BaseT used all 8 pins. So what pins
supply the power? I'm guessing that it can't do gig and power at the
same time. Can anyone verify that? Here's the parts listing -

On PoE over the switches, you are absolutely correct.
However, on the Power Patch Panels, that is not a "standard"
implementation, and it uses the 4-5 and 7-8 pairs.

Just a clarification, power is not using the extra pair...it uses the
same pair.
Thanks!!!

No, power over ethernet does not work "through" other devices like hubs
and stuff like that.... You can purchase a powered patch panel, which
works in between a hub and your jack supplying power over the "extra"
pairs in an ethernet outlet...
As for configuration, the default is "auto" so nothing is really needed
unless you explicitly need to turn it off for some reason.

Hi, group
Two questions about PoE, first, If I connect a VoIP telephone to
Cat3550PWR without a direct line. Through a hub, or other outlets. Could
the Voip telephone get the power from Car3550PWR?
Secondly, Need I config some command for the PoE ?
