6500 power considerations

Unanswered Question
Apr 18th, 2008

Should I get 6500s with 6000w power supplies or less? What is the consideration in a server farm environment where there's no POE?

I have this problem too.

Salamat...

Some things to consider:

0.) What model 6500 chassis will you deploy?

1.) What cards will you populate the chassis with?

2.) How much power does each module consume and what is its current draw?

3.) How much current and power is each port on each module capable of delivering?

4.) Do you want to run an active/standby power supply paradigm or a load sharing active/active paradigm?

This should be a good start...

hi Victor,

we are deploying 6509-E switches with SUP720. They will have atleast 5x 6748 and 1x6704.

There is no PoE.

Thanks,

Fawad

If you have access to it, the power calculator tool will show you power demand relative to different power supplies within the 6500 chassis.

Fawad:

The sup-720 consumes about 400W, depending on the model.

Allow about 400W for each 6704 module (you should probably order 2, not just 1, for module diversity for your uplinks).

I cant find the power consumption ratings for the 6748.

Do you have a Cisco sales rep? I am sure Cisco will be more than happy to help you order what you need. I dont see any need for the 6000W power supply, thats for sure.

Sorry I couldnt be more help.
