Actually,

The 1400 WAC (PWR C45-1400AC) DOES NOT provide PoE.

The 1400 WDC-P (PWR C45-1400DC-P) does provide poe but it's a DC PS

See Table 8. Cisco Catalyst 4500 E-Series Power-Supply Specifications (Data-Only Power Supplies)

Also

See Table A-7 1400 W AC-Input Power Supply Specifications

Power over Ethernet: Not supported

Yes it does -

You should use the power calculator for which there is a link in the doc above.

You can run the power supplies in redundant or combined mode. Combined mode means both power supplies are used to power devices. Obviously if one power supply fails you then lose power to devices.

Alejandro

Apologies for the incorrect information.

Don't worry, it happens because there are two flavors of 1400W... it's always confusing
