Chapter 2 Preparing to Install the Router
Safety Recommendations
•Locate the emergency power-off switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly turn off the power.
•Disconnect all power before doing the following:
–Installing or removing a chassis
–Working near power supplies
•Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety grounds.
•Do not work alone if hazardous conditions exist.
•Never assume that power is disconnected from a circuit. Always check.
•If an electrical accident occurs, proceed as follows:
–Use caution; do not become a victim yourself.
–Turn off power to the device.
–If possible, send another person to get medical aid. Otherwise, assess the victim’s condition and then call for help.
–Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.
In addition, use the following guidelines when working with any equipment that is disconnected from a power source, but 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 it.
•Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at the network interface.
•Use caution when installing or modifying telephone lines.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It can occur if electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing modules:
•Ensure that the router chassis is electrically connected to earth ground.
•Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to channel unwanted ESD voltages safely to ground. To guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
•If no wrist strap is available, ground yourself by touching a metal part of the chassis.
Caution For the safety of your equipment, periodically check the resistance value of the antistatic strap. It should be between 1 and 10 megohms (Mohm).
