2700 W Power Supply Specifications
Ta b l e A - 2 2 lists the specifications for the 2700 W AC-input power supply.
Table A-21 2700 W AC-Input Power Supply Specifications
Specification Description
AC-input type Autoranging input with power factor correction (PFC).
NotePower factor correction is a standard feature on all Catalyst 6500 
series AC-input power supplies. PFC reduces the reactive 
component in the source AC current allowing higher power 
factors (typically 99 percent or better) and lower harmonic 
current components.
AC-input voltage
Low-line (120 VAC nominal)—90 VAC (min) to 132 VAC (max)
High-line (230 VAC nominal)—170 VAC (min) to 264 VAC (max)
AC-input current
16 A maximum at 230 VAC at 2700 W output
16 A maximum at 120 VAC at 1350 W output
AC-input frequency 50/60 Hz (nominal) (±3% for full range)
Branch circuit requirement  Each chassis power supply should have its own dedicated, fused-branch 
circuit:
For North America—20 A
For International—Circuits sized to local and national codes
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.
–For high-line operation, the power supply operates with the hot 
conductor wired to a source AC phase and the neutral conductor 
wired either to ground or to another source AC phase as long as 
the net input voltage is in the range of 170 to 264 VAC.
–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.

  3000 W AC-Input Power Supply
3000 W AC-Input Power Supply
The 3000 W AC-input power supply (WS-CAC-3000W) is supported in the following Catalyst 6500 
series switches:
Catalyst 6506
Catalyst 6506-E
Catalyst 6509
Catalyst 6509-E
Catalyst 6509-NEB
Catalyst 6509-NEB-A
Catalyst 6509-V-E
Catalyst 6513
Catalyst 6513-E
The 3000 W power supply (see Figure A-13) shares the same form factor as the 1000 W, 1300 W, 
2500 W, 4000 W, and 6000 W AC-input power supplies.
NoteThe 3000 W AC-input power supply needs 220 VAC to deliver 3000 W of power. When operating with 
110 VAC, it delivers only 1400 W. In addition, the power supply needs 16 A, regardless of whether it is 
plugged into 110 VAC or 220 VAC.
