Full Power Redundancy with Catalyst 6513?

[gbryant]

Hello All,

I am in search of a critical answer. The 6513 has two possible power supplies a 2500W and 4000W. The cisco document on the web states that you must use 220 power to have the capacity of 2500W. They also state that a fully populated 6513 Chassis will not be fully redundant. So, my question is will dual 4000W power supplies provide full redundancy? And how do I determine the Min. AMP needed? on the 2500W it is16A. I believe it should be 32A on the 4000W.

Thanks...

Greg,

This might not answer all your questions but I hope the information proves helpful.

Total power available with the 2500 Watts Power supply = 55.50 Amps

Total power available with the 4000 Watts Power supply = 95.76 Amps ENG-52881

(requires single phase 30A 220VAC circuit)

Also see the following URL for a lot of good power information (including information on the WS-CAC-4000W-US): http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/6000hw/inst_aug/02prep.htm

Hope this helps,

Don

I'm facing the same question and in my research I'm coming to the conclusion that the comment about "fully populated" means with inline power. The 6509s and 6513 I have now I can't see any combination of cards without inline power exceeding the output of the 2500W power supply.

Are your figures based around 240volts or 120volts for the 2500 watt PSU? This has a direct bearing on the current delivered
