Configuration
Chassis running at high
activity, with four 10-Gigabit
Ethernet XFPs, two MICs,
and fans running at high
speed
Table 27 on page 55 lists the power requirements for various hardware components when
the router is operating under typical voltage conditions.

MX Series Interface Module Reference
The following calculations show the typical power consumption for modular AC-powered
routers @ 220 V (includes 85% efficiency):
Active AC-powered router with one MIC:
Base router (high activity, with four 10-Gigabit Ethernet XFPs, and fans running at high
speed) + 1 MIC =
282 W + 41 W = 323 W
Active AC-powered router with two MICs:
Base router (high activity, with four 10-Gigabit Ethernet XFPs, and fans running at high
speed) + 2 MICs
282 W + 2(41 W)= 364 W
Example of calculating system thermal output:
Watts AC PEM * 3.41 = BTU/hr
500 W * 3.41 = 1,705 BTU/hr
