They are designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system. Follow these basic guidelines when you are working with any electrical equipment: • Before beginning any procedures requiring access to the chassis interior, 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 chassis. • 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 guidelines that follow when working with any equipment that is disconnected from a power source but is still connected to telephone wiring or other network cabling. • 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.
