C6K5-SUP720 running in Chassis with 1300Watt PS

Hi,

I know that FAN2 and SUP720 are requiring a minimum

of one 2500Watt-PS.

Is it possible to use it in a Chassis with two 1300Watt-PS, if the redundancy-mode is disabled.

IOS-Switch#conf t

IOS-Switch#(config)power redundancy-mode combined

IOS-Switch#(config)

%C6KPWR-SP-4-PSCOMBINEDMODE: power supplies set to combined mode.

IOS-Switch#(config)end

IOS-Switch#

IOS-Switch#sh power

system power redundancy mode = combined

system power total = 2306.64 Watts (54.92 Amps @ 42V)

system power used = 712.32 Watts (16.96 Amps @ 42V)

system power available = 1594.32 Watts (37.96 Amps @ 42V)

I think it should be possible ??

Thanks in Advance

Re: C6K5-SUP720 running in Chassis with 1300Watt PS

It should work, but I would worry about how it'll perform when you start loading it with GBICs and clients. You'll probably run over the threshold where you can support the switch is one of those PS fails.

You might put yourself in a situation where you've created a two-points of failure system.
