Calculate Power Requirements of an MX10004 Router
Use the information in this topic to calculate power requirements of your MX10004 configuration. You also need to determine the number of power supplies required for different MX10004 router configurations.
To ensure adequate power and to avoid triggering an alarm, we recommend that you maintain n+1 power supplies in your router at all times. Replace failed power supplies immediately to prevent unexpected failures.
If a new line card is installed in an operational router, power management does not power on the line card if the increased power demand exceeds the total available power, including redundant power. If redundant power is used to power on the line card, a minor alarm is raised. The minor alarm becomes a major alarm if the condition is not corrected.
The calculations in this topic represent the maximum power requirements that you need to budget for your MX10004 router configuration. The power consumption of your router will be less than the calculated results shown here. Power consumption will vary based on the hardware and software configuration of your router, the amount of traffic passing through the line cards, and environmental variables such as room temperature.
Before you begin these calculations:
-
Ensure that you understand the different router configurations. See MX10004 Components and Configurations.
-
Ensure that you know the power requirements of different router components. See Power Requirements for MX10004 Components.

How to Calculate the Power Consumption of Your MX10004 Router Configuration
Use the following procedure to determine the maximum power you need to supply to the router. To calculate maximum system power consumption, you first determine the combined maximum internal power requirements of all the router components and then divide this result by the power supply output power.

How to Calculate the Number of Power Supplies Required for Your MX10004 Configuration
The minimum power configuration for MX10004 routers is three power supplies. However, using the calculated minimum power configuration doesn’t prevent the system from triggering a power alarm. To ensure that you don’t trigger power alarms with a fully loaded chassis, you must configure your router for dual feed and high-power settings.
