Calculating AC Power Requirements for MX2010 Routers
The information in this topic helps you determine which of the two input ratings for the PSM is suitable
for various configurations. You determine suitability by subtracting the total power draw from the maximum
output of the PSMs. Afterward, you calculate the required input current. Finally, you calculate the thermal
output.
We recommend that you provision power according to the maximum input current listed in the power
system electrical specifications.
Use the following procedures to calculate the power requirement:
1. Calculate the power requirement.
2. Evaluate the power budget.
3. Calculate input power.
4. Calculate thermal output (BTUs) for cooling requirements.
