NOTE: The HVAC/HVDC power supply, JNP10K-PWR-AC2, has a set of dip switches on the
faceplate that allows you to configure the power supply for either high power (30 A) or low
power (20 A) input mode. If any JNP10K-PWR-AC2.power supply is set to 20 A, then the power
budget for all power supplies installed in the system becomes 20 A, regardless if other power
supplies are set at 30 A. This design is to prevent overloading of the power supply that is set
to 20 A. See Power Input and Output Voltages for JNP10K-PWR-AC2 Power Supplies for details
on setting the dip switches.
2. Determine the total power required for your configuration with line cards installed. The total power
available to the chassis is calculated by dividing the wattage needed by the power rating, then rounding
up.
