Cisco::Switch::Inline Power
Worth noting: the "old" inline power modules from Cisco provide "Cisco proprietary" inline power to Cisco devices. The new "AF" standard modules provide the "new" standard POE power.
And the 4506 switches can have a limited power capacity that must be planned for. There is a calculator at:
http://tools.cisco.com/cpc/launch.jsp
I can't fill up my 4506 chassis with inline power modules and provide power to all the modules and still have redundancy for the 2800W power supply.
This link contains more details about power supplies and providing inline power with 4500 series switches:

It is possible to add an external power source using a "shelf" and installing power supplies in it to provide for power supply redundancy:
WS-P4502-1PSU
Catalyst 4500 Aux. Power Shelf (2 slot), incl. one PWR-4502
PWR-4502
Catalyst 4500 Aux. Power Shelf Redundant Power Supply
To get one each of the above would be about $6K

Is a whitepaper with good information about this issue and options available.
In all I would not recommend going the power shelf route. Just be sure to only connect 222 powered phones maximum.
