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.
