950 W AC-Input and DC-Input Power Supplies Specifications (continued)
Appendix A
Specification
Each chassis power supply should have its own
dedicated, fused-branch circuit:
For North America—15 A
•
For International—Circuits sized 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.
