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, and then
rounding off the result.
In the previous examples, we calculated that an MX10016 AC power system requires 22800 W with 16 line cards.
In this example, we calculate the total power available for this configuration:
(25450 W) / (2700 W) = 9.42
Round up the result to 10 AC power supplies.
JNP10K-PWR-AC Power Specifications
An MX10016 router in redundant configuration can use either AC or DC power supplies; base configuration
routers are AC power only.
Table 35 on page 102 lists the power specifications for the AC power supply (JNP10K-PWR-AC) used in
an MX10016 chassis.
