Planning for Power Requirements
• Power mode to use and the number of additional power supplies required for that mode
You must also ensure that the circuit used for the switch is dedicated to the switch to minimize the possibility
of circuit failure.
When you know the amount of power that is required for operations (available power) and redundancy (reserve
power), you can plan for the required number of input power receptacles within reach of the switch location.
Step 1 Determine the power requirement for the switch by summing the maximum wattage for each installed module (see the
following table).
