We are faced with having to replace all of our Cisco 6500 switches because of end-of-life on all components by 2011. When I replace these devices I will have to provide POE capabilities to support plans to migrate to IP phones. I have taken this into consideration and will replace existing power supplies with the WS-CAC6000W model.
I'm planning on providing dual 220VAC input in order to get the max. power output of 6000W from the power supplies.
My planned configuration:
Chassis- 6506-E/6509-E/6513
Sup. Card - Sup32 at the access layer and Sup720 at the Core and Distribution layer.
Line Card - Ws-X6148A-45-AF
Power Supply - Dual 6000 watt
Power Input - Dual 220V
Questions:
1. Taking the worse case scenario of a fully populated 6509 or 6513 supporting the max. Class 2 devices; is the above configuration adequate to provide this service?
2. How much current and power will the power supplies draw from the input source in the worse case scenario?
3. Should I be concerned about heat dissipation?
4. If I request dual 220V 20Amp circuits from our facility group, is this adequate and correct?

Alfredo,
As you have various Chassis and Supervisor, I recommend using Cisco's power calculator at http://www.cisco.com/go/powercalculator and customize the chassis to your liking.
Once you've entered all the information, a PDF report will be produced which you can keep for your records.
Please send my regards to Erik Molden.

I have used the power calculator.
My concern is the input power requirements and heat dissipation.
When I ran the calculations for a 6509-E, the results came out with a single/redundant 6000w with dual input to be using approx. 66.32%. Is this percentage acceptable?

The input power requirement and heat dissipation is included in the power calculator tool, please run a model of the hardware and you should see the appropriate output.
66.32% is acceptable.
