[nsp] Power requirements for switches

[Z]

Hi peoples,

   I'm wondering what power requirements there are for a Catalyst
6506 ( no voice just data ) and a Catalyst 4506 are in terms of what
I should be telling my data center folks.  Would either of these
require its own 25A circuit for each power supply?   Also, are the
Catalysts anything like some switches that autosense the power and
only power-up certain portions of the switch if it autosenses like
100VAC instead of 200VAC?


Thanks for your help in advance my friends
