Cisco 4500 Power Supplies

I've had several times where the question of what type of power does a switch require has come up during design and installs. How much PoE can it provide if we use this power supply or that one?

Here's a handy little web page from Cisco that I always struggle to find... It's all on the 4500 series power supplies and PoE capabilities and is great for determining whether you can plug in your switch or not...

Oh and I apologize for the lack of virtual-ness in the post, but I'm afraid that's how my posts will be. :)
