Power Requirements for Switch Modules
To determine the number of power supplies required to operate all the modules in a switch, add together the
maximum power amounts for each module in the switch, divide the sum by 3000 W, and 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 together the typical power amounts for each module in the switch.
If you order new power supplies, make sure that the new power supplies use the same type of power (AC or
DC) as the rest of the power supplies in the same 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, 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.
