Power Specifications
Power specifications include the specifications for each type of power supply module.
Power Requirements for Switch Modules
Determine the number of power supplies required to operate all the modules in a switch by adding the maximum
power amounts for each module in the switch. Then divide the sum by 3000 W. If there is a fractional amount
in the result, add 1 to the result. For n+1 redundancy, add one more power supply. For n+n redundancy, double
the number of power supplies and provision for a second power source.
To determine the typical consumption, add the typical power amounts for each module in the switch.
Make sure that any new power supplies use the same type of power (AC or DC) as the rest of the power
supplies in the switch. Do not use a mix of AC and DC power sources for a switch.
Maximum Power Available to the Switch
The maximum power available for operations depends on the input power from your power source. Also, the
number and output capabilities of your power supplies, and the power redundancy mode that you use. The
following table lists the amount of power available for 3-kW power supplies depending on power inputs,
numbers of power supplies, and the mode used.
