Installation
Warning Before working on equipment that is connected to power lines,
remove jewelry (including rings, necklaces, and watches). 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 switch in the room in which you are working.
Then, if an electrical accident occurs, you can act quickly to shut the power off.
• Before working on the system, turn off the power and unplug the power cord.
• Disconnect all power before doing the following:
— Installing or removing a router
— Working near power supplies
— Performing a software upgrade
• Do not work alone when potentially hazardous conditions exist.
• Never assume that power has been disconnected from a circuit. Always check.
• Look carefully for possible hazards in your work area, such as moist floors,
ungrounded power extension cables, and missing safety grounds.
• If an electrical accident occurs, proceed as follows:
— Use caution; do not become a victim yourself.
— Turn off power to the system.
— If possible, send another person to get medical aid. Otherwise, assess the
condition of the victim and then call for help.
— Determine if the person needs rescue breathing or external cardiac
compressions; then take appropriate action.
Inspecting the System
Do not unpack the router until you are prepared to install it. If the final installation site
will not be ready for some time, keep the router in the shipping container to prevent
accidental damage. When you have determined where you want the router installed,
proceed with the unpacking. The router, cables, publications, and any optional
equipment you ordered might be shipped in more than one container. When you
unpack each shipping container, check the packing list to ensure that you received all
of the following items:
• Router
• 6-foot (1.8-meter) power cord
