MX104 AC Power Electrical Safety Guidelines and Warnings

The following electrical safety guidelines apply to an AC-powered router:
You can order three-wire electrical cords with a grounding-type plug that fits only a
grounding-type power outlet. Do not circumvent this safety feature. Equipment
grounding should comply with local and national electrical codes.
Each AC power supply has one AC appliance inlet. Each inlet requires a dedicated AC
power feed and a dedicated customer-site circuit breaker. For the recommended circuit
breaker rating, see "MX104 AC Power Specifications" on page
WARNING: The router is pluggable type A equipment installed in a
restricted-access location.
The power cord serves as the main disconnecting device for the AC-powered device.
The socket outlet must be near the AC-powered device and be easily accessible.
The cores in the main lead are colored in accordance with the following code:
Green and yellow—Earth
Blue—Neutral
Brown—Live
When a router is equipped with two AC power supplies, you must unplug both power
cords (one for each power supply) to completely disconnect power to the router.
