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 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
