Calculating Power Consumption for Your Configuration
These examples use generalized values per MIC. For exact MIC power requirements, see the MX Series Interface Module Reference.
The following calculations show the typical power consumption (at 25° C) for modular routers :
Fully loaded AC-powered router with four fan modules, two MPCs, two JNP-MIC1 MICs, and two RCBs :
Router (idle at 25° C, with QSFP28 optics) with 4 fans (running at normal speed) + 2 MPC + 2 MIC + 2 RCBs= 80 W + 1320 W + 160 W + 116 W = 1676 W
Output power in watts / power supply efficiency @90% = power consumption in watts 1676 W / 0.9 = 1862 W
Fully loaded AC-powered router with four fan modules, two MPCs, two JNP-MIC1-MACSEC MICs, and two RCBs:
Router (idle at 25° C, with QSFP28 optics) with 4 fans (running at normal speed) + 2 MPC + 2 MIC + 2 RCBs= 90 W + 1320 W + 220 W + 116 W = 1736 W
Output power in watts / power supply efficiency @90% = power consumption in watts 1736 W / 0.9 = 1929 W
The following calculations show the maximum power consumption (at 55° C) for modularrouters :
Fully loaded AC-powered router with four fan modules, two MPCs, two JNP-MIC1 MICs, and two RCBs:
Router (idle at 55° C, with QSFP28 optics) with 4 fans (running at normal speed) + 2 MPC + 2 MIC + 2 RCBs= 380 W + 1430 W + 170 W + 130 W = 2110 W
Output power in watts / power supply efficiency @90% = power consumption in watts 2110 W / 0.9 = 2345 W
Fully loaded AC-powered router with four fan modules, two MPC, two JNP-MIC1-MACSEC MICs, and two RCBs:
Router (idle at 55° C, with QSFP28 optics) with 4 fans (running at normal speed) + 2 MPC + 2 MIC + 2 RCBs= 380 W + 1430 W + 240 W + 130 W = 2180 W
Output power in watts / power supply efficiency @90% = power consumption in watts 2180 W / 0.9 = 2422 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, with QSFP28 optics, and JNP-MIC1 at 25° C typical temperature to be 1676 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 1,676 W * 3.41 = 5,715.16 BTU/hr
