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

AC Power Circuit Breaker Requirements for the MX5, MX10, MX40, and MX80 Router
We recommend that you use a dedicated customer site circuit breaker rated for
15 A (110 VAC) minimum or 10 A (220 VAC) minimum for each AC power feed, or as
required by local code. Doing so enables you to operate the router in any configuration
without upgrading the power infrastructure.
AC Power Cord Specifications for MX5, MX10, MX40, and MX80 Routers
Each AC power supply has a single AC appliance inlet located on the power supply that
requires a dedicated AC power feed. Most sites distribute power through a main conduit
that leads to frame-mounted power distribution panels, one of which can be located at
the top of the rack that houses the router. An AC power cord connects each power supply
to the power distribution panel.
You can order detachable AC power cords, each approximately 8 ft (2.5 m) long that
supply AC power to the router. The C13 appliance coupler at the female end of the cord
inserts into the AC appliance inlet coupler, type C14 as described by International
Electrotechnical Commission (IEC) standard 60320. The plug at the male end of the
power cord fits into the power source receptacle that is standard for your geographic
location.
Table 18 on page 37 provides specifications on the AC power cord provided for each
country or region.
