•Never assume that power is disconnected from a circuit; always check.
•Keep tools and assembly components away from walk areas.
•Do not work alone if potentially hazardous conditions exist.
•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
•Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
Safety with Electricity
Follow these basic guidelines when working with any electrical equipment:
•Before beginning 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 and external cables before installing or removing a router.
•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.
•If an electrical accident does occur, proceed as follows:
–Use caution; do not become a victim yourself. 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.
–Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.
In addition, observe the following guidelines when working with any equipment that is disconnected from a power source but still connected to telephone or network wiring:
•Never install telephone wiring during a lightning storm.
•Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
•Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
Use caution when installing or modifying telephone lines.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage to circuit boards can occur if they are handled improperly. Such mishandling can result in intermittent or complete failures of the board.
When handling circuit boards, observe the following guidelines to prevent ESD damage.
