2500 W AC-Input and DC-Input Power Supplies 
The 2500 W AC-input power supply (WS-CAC-2500W) and 2500 W DC-input power supply 
(WS-CDC-2500W) are 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 6513
The 2500 W power supplies, shown in Figure A-9 and Figure A-10, share the same form factor as the 
1000 W, 1300 W, 3000 W, 4000 W, and 6000 W AC-input power supplies.
Note With a fully populated Catalyst 6513 switch, two 2500 W power supplies are not fully redundant. If you 
operate the 2500 W power supply at the low range input (100 to 120 VAC), it is not redundant in a fully 
populated Catalyst 6509, Catalyst 6509-E, Catalyst 6509-NEB, or Catalyst 6509-NEB-A switch.
Note The 2500 W AC-input power supply needs 220 VAC to deliver 2500 W of power. When powered with 
110 VAC, it delivers only 1300 W. In addition, the power supply needs 16 A, regardless of whether it is 
plugged into 110 VAC or 220 VAC.
