Chapter 2 Preparing for Installation
Safety and Compliance
General Safety Guidelines • Never attempt to lift an object that might be too heavy for you to lift by
yourself.
Caution Do not attempt to lift the chassis by the blower module handle. The blower module
handle is intended for lifting the blower module only when it is disconnected from
the chassis.
• Always disconnect the power source and unplug all power cables before
lifting, moving, or working on the router.
• Keep the work area clear and dust free during and after installation.
• Keep tools and router components away from walkways and equipment rack
aisles.
• Do not wear loose clothing, jewelry (including rings and chains), or other
items that could get caught in the router.
• Fasten your tie or scarf and sleeves.
• Cisco equipment operates safely when it is used in accordance with its
electrical ratings and product usage instructions.
• Do not work alone if potentially hazardous conditions exist.
• Always unplug the power cables when performing maintenance or working
on the router, unless the replacement part is hot swappable and designed for
online insertion and removal (OIR).
• The installation of the router should 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) 364, part 1 through part 7.
• Before installing, configuring, or maintaining the router, review the safety
warnings listed in the Regulatory Compliance and Safety Information for the
Cisco 12000 Series Router (Document Number 78-4347-xx) that
accompanied your router.
