4500 Series AC Power Shelf, or the Catalyst 4500 Series Power Entry Module and
External Power Shelf Installation Note.
To provide PoE with the 48-port PoE 10/100/1000BASE-T switching module in
a Catalyst 4500 series switch, you must have an PoE-enabled power supply. All
power supplies support PoE except the 1000 W and 1400 W AC power supplies.
Auto MDIX is not supported on PoE enabled switching modules.
