Cisco Systems 2140, 2130 manual Preventing Electrostatic Discharge Damage

Chapter 2 Preparing to Install the Cisco ADE 2130 and 2140 Series Appliance

Safety Guidelines

•Carefully examine your work area for possible hazards, such as moist floors, ungrounded power extension cables, and missing safety grounds.

•Never assume that power is disconnected from a circuit; always check.

•Never perform any action that creates a potential hazard to people or makes the equipment unsafe.

•Never work alone when potentially hazardous conditions exist.

•If an electrical accident occurs, proceed as follows:

–Use caution, and do not become a victim yourself.

–Turn off power to the appliance.

–If possible, send another person to get medical aid. Otherwise, determine the condition of the victim, and then call for help.

–Determine whether the person needs rescue breathing, external cardiac compressions, or other medical attention; 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 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. ESD can occur when electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. Always follow ESD-prevention procedures when removing and replacing components:

•When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are ready to install the component in your appliance. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.

•When transporting a sensitive component, first place it in an antistatic container or packaging.

•Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.

•Ensure that the Cisco ADE 2130 and 2140 Series appliance is electrically connected to earth ground.

•Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Attach the antistatic wrist strap to your wrist and connect its cord to the ESD socket on the top, left-hand side on the front of the appliance 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 appliance.

Caution For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. It should be between 1 and 10 Mohm.
