Safety and Regulatory Compliance Information
General Electrical Safety Guidelines
Install the router in compliance with the following local, national, or
international electrical codes:
United States—National FireProtection Association (NFPA 70), United
States National Electrical Code.
Canada—Canadian Electrical Code,Part 1, CSA C22.1.
Other countries—International Ele ctromechanical Commission (IEC)
60364, Part 1 through Part 7.
Evaluated tothe TN power system.
Locate the emergencypower-off switch for the room in which you are working
so that if an electrical accidentoccurs, you can quickly turn off the power.
Do not work alone if potentially hazardousconditions exist anywhere in
your workspace.
Never assume that poweris disconnected from a circuit. Always check the
circuit before starting to work.
Carefully look for possiblehazards in your work area, such as moist floors,
ungrounded powerextension cords, and missing safety grounds.
Operate the router within markedelectrical 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 equ ipment,
and make certain they are in goodcondition.
Many router componentscan be removed and replaced without powering down
or disconnecting power tothe 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 electricalsafety guidelines apply to DC-powered routers:
DC-poweredrouters are equipped with a DC terminal block that is rated for the
power requirementsof a maximally configured router. To supply sufficient
power,t erminate the DC input wiring on a facility DC source capable of
supplying at least 65 A @ 48 VDC. The 48 VDC facility DC sourceshould be
equipped with a circuitbreaker rated at 90 A minimum. Incorporate an easily
accessible disconnect device into the facility w iring. Be sure to connect the
