Question about Cisco 6500 current draw Values

I am questioning the current draw values shown on the below URL for the Cisco 6500:

http://www.cisco.com/en/US/products/hw/switches/ps708/products_installation_guide_chapter09186a008007eb89.html

For a 1300 W power supply the docs indicate a 20A circuit is required; however, using the table in the above URL, one can see that the 20A

Circuit will soon be overloaded when populating the chassis with cards, especially the 720 sup.

I was wondering whether someone could shed some light on the subject.

Thanks

Fahad

Hi Fahad,

The 1000 W power supply requires a 15 A or 20 A circuit. That means, Sup 720 may be needing 15amps also, which need not get overloaded.

Re: Question about Cisco 6500 current draw Values

The 20A requirement does not automatically mean you are drawning 20A continuously. If fact a 1300W power supply will draw about 11.8A. However, we first must determine the load to the 1300W power supply. This is done by first identifying the blades that will be installed and QTY. Can you provide this information? Without it no one can effectively answer your question
