Cisco 4500X power Consumption

[ngtransge]

Hello,

I am calculating Cisco 4500X power consumption requirements to select appropriate UPS systems. I have 4500X switch with dual power supplies.

Question  is which value should I take for power consumption calculation, in data sheet it has two values:

AC Power Max Rating: 750W

System Power Consumption: 330W nominal/400W max

Which values should I take, to calculate UPS systems capacity ?

And also I am interesting when 4500x has two power supplies what is power consumption?

Hi,

The max power draw is 400W for the chassis with the power supply being 750W.  So, if you get your UPS based on the max of 400W, you should be fine.

Hello Reza,

Thank you for helping.

I am interesting is power consumption is same when switch is using additional redundant power supply?

Hi,

According to the data sheet, the 400W is the max regardless of how many power supplies you put in there.  The 400 is what the whole switch draws.

Is that more clear?

Cisco Power Calculator ( http://tools.cisco.com/cpc/launch.jsp ) is great for these kind of calculations.

mfurnival,

The 4500X series is new and is not part of the power calculator yet.
