4500 Power supply question

Hello,

I've been reading this document:

http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps4324/product_data_sheet09186a00801f3dd9.html

And I've seen that there are two “data only” power supplies (1000W and 1400W) that doesn't provide PoE. But the 1300W power supply can provide data and PoE. What is the difference between the 1300 and 1400 W power supplies? Does anybody know why can't the 1400 W provide PoE?

I suppose that the “data + PoE” power supply has two outputs, one to provide power to the chassis and the modules and another one to provide PoE, isn't it?

Thanks in advance,

Here is some related information:

Variable Wattage—These power supplies automatically adjust the wattage to accommodate PoE and system power requirements.

1400 W DC—Supports up to 1400 W of system power and variable amounts of PoE, depending on the input feed to the power supply.

The Catalyst 4500 series switches support the following power supplies:
