Chapter2 Preparing for Installation Safety
Warning
The ports labeled “10BaseT”, “100BaseTX”, and “10/100” are safety extra-low voltage (SELV)
circuits. SELV circuits should only be connected to other SELV circuits. Avoid connecting these
circuits to telephone network voltage (TNV) circuits.
Warning
There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only
with the same or equivalent type recommended by the manufacturer. Dispose of used batteries
according to the manufacturer’s instructions.
Working with Electricity
Follow these guidelines when working on electrical equipment:
Locate the emergency power-off switch for the room in which you are working. If an electrical
accident occurs, you can act quickly to turn off the system.
Disconnect all power by powering off the system and unplugging the power cord before:
Installing or removing a chassis
Working near power supplies
Do not work alone if potentially hazardous conditions exist.
Never assume that power is disconnected from a circuit; always check the circuit.
Look carefully for possible hazards in your work area, such as moist floors, underground power
extension cables, frayed power cords, and missing safety grounds
If an electrical accident occurs:
Use caution: do not become a victim yourself.
Power off the system.
If possible, send another person to get medical aid. Otherwise, assess the victim’s condition,
then call for help.
Determine if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
Disconnect all power and external cables before installing or removing a chassis.
Never install equipment that appears damaged.
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.
Always use caution when installing or modifying telephone lines.
Never perform any action that creates a potential hazard to people or makes the equipment unsafe.
