Cisco CATALYST 6509E 9 SLOT 15U CHASSIS NO POWER SUPPLY NO FAN TRAY Specification Guide

Branch circuit requirement (AC-input)

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.
