• Power mode to use and the number of extra power supplies required for that mode.
Ensure that the circuit that is used for the switch is dedicated to the switch to minimize the possibility of circuit
failure.
Calculate the power that is required for operations (available power) and redundancy (reserve power), then
you can plan for the required number of input power receptacles. The power receptacles will be within reach
of the switch location.
Step 1 Determine the power requirement for the modules in the switch by summing the maximum wattage for each installed
module, see the following table.
