MX204 Power Planning
Power Consumption for an AC-Powered MX204 Router
Use the information in this topic to determine the power consumption for your router and plan the amount of power you need to provide to the router.
Power Requirements for MX204 Components
Table 1 lists the power requirements for various hardware components when the router is operating under typical and maximum voltage conditions.
Component | Power Requirement at 25° C (Watts; Typical) | Power Requirement at 55° C (Watts; Maximum) |
|---|---|---|
Fully loaded MX204 router | 240 W | 280 W |
Table 2 lists the power requirements for the fully configured AC-powered routers operating under typical voltage conditions.
Chassis Configuration | Power Requirement at 25° C (Watts) | Power Requirement (Watts) with 90% Efficiency |
|---|---|---|
Fully configured chassis running at high activity | 240 W | 266 W |
Table 3 lists the power requirements for the fully configured AC-powered routers operating under maximum voltage conditions.
Chassis Configuration | Power Requirement at 55° C (Watts) | Power Requirement (Watts) with 90% Efficiency |
|---|---|---|
Fully configured chassis running at high activity | 280 W | 311 W |
Calculating System Thermal Output
After you have calculated the power consumption for your configuration, you can use that information to determine the system thermal output (BTUs per hour). To do so, multiply the power consumption in watts by 3.41.
For example, in Table 2 we calculated the power consumption for a fully configured chassis running at high activity at 25° C typical temperature to be 240 W. Using that information we can calculate the system thermal output for the configuration:
Power consumption in watts * 3.41 = system thermal output in BTU/hr 240 W * 3.41 = 818.4 BTU/hr
