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:
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
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?
