As per the installation guide, The 1400 W DC multi-input supply can not be used with other power supply types, but other power supplies in this product line work with the other types during an upgrade. If you mix power supplies in a Catalyst 4500 series chassis, the switch detects the type of power supply in power supply bay 1 (PS1) and ignores the power supply in power supply bay 2 (PS2) while issuing system messages and showing the power supply in bay 2 as in the err-disable state in the output of the show power command. When the power supply in bay 1 is removed, the switch recognizes the power supply in bay 2, and you may then put a new matching power supply in bay 1. Both supplies should now resume normal function.
