Safety with Electricity
unplugging a PDU. Refer to the documentation for individual components for complete information about
removing power from a component.
Follow these guidelines when working with any electrical equipment:
• Install the Cisco R42612 rack in compliance with national and local electrical codes. In the United States,
the relevant code is National Fire Protection Association (NFPA) 70, United States National Electrical
Code. In Canada, the relevant code is Canadian Electrical Code, part I, CC22.1. In other countries, you
should observe the standards of the International Electrotechnical Commission (IEC) 364, part 1 through
part 7.
• Remove all jewelry (including rings, necklaces, and watches) before working on equipment that is
connected to power lines. Metal objects will heat up when connected to power and ground and can cause
serious burns or weld the metal object to the terminals.
• Locate the emergency power-off breaker switch for the room where you are working before starting any
procedures that require access to the interior of the rack.
• Disconnect all power and external cables before installing or removing a PDU or Cisco R42612 rack.
• Do not work alone when potentially hazardous conditions exist.
• Never assume that power has been disconnected from a circuit; always check.
• Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
• Never install equipment that appears damaged.
• Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension
cables, and missing safety grounds.
In addition, use the following guidelines when working with any equipment that is disconnected from a power
source, but still connected to network cabling.
• Never install network wiring during a lightning storm.
• Never install network jacks in a wet location unless the jack is specifically designed for wet locations.
• Never touch non-insulated wires or terminals unless the line has been disconnected at the network
interface.
• Use caution when installing or modifying lines.
• Read the installation instructions before you connect the system to its power source.
Warning Connect the device to a grounded power outlet.
Warning For Nordic countries (Norway, Finland, Sweden and Denmark) this system must be installed in a Restricted
Access Location, where the voltage of the main ground connection of all equipment is the same (equipotential
earth) and the system is connected to a grounded electrical outlet.
