Calculating Power Requirements for MX960 Routers

The information in this topic helps you determine which power supplies are suitable for various
configurations, as well as which power supplies are not suitable because output power is exceeded. You
determine suitability by subtracting the total power draw from the maximum output of the power supplies.
Afterward, the required input current is calculated. Finally, you calculate the thermal output. A sample
configuration is provided in
We recommend that you provision power according to the maximum input current listed in the power
supply electrical specifications (see
and "Electrical Specifications for the MX960 DC Power Supply" on page
Use the following procedures to calculate the power requirement:
1. Calculate the power requirement.
2. Evaluate the power budget.
