Appendix A Power Supply Specifications
6000 W AC-Input Power Supply
System power dissipation 7034 W
Branch circuit requirement (AC-input) Each power supply input should have its own
dedicated, fused-branch circuit:
• For North America—20 A
• For International—Circuits should be sized
according to local and national codes
• All Catalyst 6500 series AC-input power supplies
require single-phase source AC.
• All AC power supply inputs are fully isolated.
– Source AC can be out of phase between
multiple power supplies in the same chassis,
which means that PS1 can be operating from
phase A and PS2 can be operating from
phase B.
– Source AC can be out of phase between AC
inputs on power supplies that are equipped
with multiple AC inputs, which means that
power cord 1 can be plugged into phase A and
power cord 2 can be plugged into phase B.
