General Electrical Safety Guidelines

Install the router in compliance with the following local, national, or
international electrical codes:
United States—National Fire Protection Association (NFPA 70), United
States National Electrical Code.
Canada—Canadian Electrical Code, Part 1, CSA C22.1.
Other countries—International Electromechanical Commission (IEC)
60364, Part 1 through Part 7.
Evaluated to the TN power system.
Locate the emergency power-off switch for the room in which you are working
so that if an electrical accident occurs, you can quickly turn off the power.
Do not work alone if potentially hazardous conditions exist anywhere in
your workspace.
Never assume that power is disconnected from a circuit. Always check the
circuit before starting to work.
Carefully look for possible hazards in your work area, such as moist floors,
ungrounded power extension cords, and missing safety grounds.
Operate the router within marked electrical ratings and product usage
instructions.
For the router and peripheral equipment to function safely and correctly, use
the cables and connectors specified for the attached peripheral equipment,
and make certain they are in good condition.
Many router components can be removed and replaced without powering down
or disconnecting power to the router, as detailed in Field-Replaceable Units
(FRUs) on page 4. Never install equipment if it appears damaged.

DC Power Electrical Safety Guidelines

The following electrical safety guidelines apply to DC-powered routers:
DC-powered routers are equipped with a DC terminal block that is rated for the
power requirements of a maximally configured router. To supply sufficient
power, terminate the DC input wiring on a facility DC source capable of
supplying at least 65 A @ 48 VDC. The 48 VDC facility DC source should be
equipped with a circuit breaker rated at 90 A minimum. Incorporate an easily
accessible disconnect device into the facility wiring. Be sure to connect the
