Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are
improperly handled, can result in complete or intermittent failures. Each PAM consists of a printed
circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors,
and a handle are integral components of the carrier. Although the metal carrier helps to protect the
cards from ESD, use a preventive antistatic strap whenever you handle the PAMs. Handle the
carriers by the handles and the carrier edges only; never touch the cards or connector pins.
Caution
These screws prevent accidental removal of the PAMs, provide proper grounding for the system, and
help to ensure that the bus connectors are properly seated in the backplane.
Following are guidelines for preventing ESD damage:

Do not work on the system or connect or disconnect cables during periods of lightning
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.
Always tighten the captive installation screws on the PAMs when you are installing them.
Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
When removing any module, connect the equipment end of the strap to one of the captive
installation screws on an installed PAM or power supply. (See Figure 9.)
