AC Power Circuit Breaker Requirements for the MX240 Router
We recommend that you use a dedicated customer site circuit breaker rated for
15 A (250 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 the MX240 Router
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 C19 appliance coupler at the female end of the cord
inserts into the AC appliance inlet coupler, type C20 (right angle) 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
geographical location.
