Safety Guidelines
Safety with Electricity
• The installation shall be in compliance with national and local electrical
codes: in the United States, National Fire Protection Association (NFPA) 70,
United States National Electrical Code; in Canada, Canadian Electrical Code,
part I, CSA C22.1; in other countries, International Electrotechnical
Commission (IEC) 60364, part 1 through part 7.
• Before you begin any procedures requiring access to the interior of the router,
locate the emergency power-off switch for the room in which you are
working.
• Disconnect all power source cables before installing or removing a router.
• Never assume that power has been disconnected from a circuit; always check.
• Carefully examine your work area for possible hazards such as moist floors,
ungrounded power extension cables, and missing safety grounds.
• Only a DC power source that complies with the safety extra-low voltage
(SELV) requirements in UL60950, CSA-C22.2 No. 60950, EN60950,
ACATS001, AS/NZS 60950,and IEC60950 can be connected to the line card
chassis DC-input power system.
• A line card chassis configured with the DC-input power system shall have a
readily accessible two-poled disconnect device incorporated in the fixed
wiring.
• The line card chassis requires short-circuit (overcurrent) protection to be
provided as part of the building installation.
• If an electrical accident occurs, proceed as follows:
– Use caution; do not become a victim. Disconnect power to the router.
– If possible, send another person to get medical aid; otherwise, assess the
condition of the victim and then call for help.
