Preventing ESD

Electrostatic discharge (ESD) damage occurs when electronic cards or components are
mishandled and can result in complete or intermittent failures. Note the following guidelines
before you install or service the system:

y

Always wear an ESD-preventive wrist or ankle strap when handling electronic components.

Connect one end of the strap to an ESD jack or an unpainted metal component on the system
(such as a captive installation screw).

y

Handle cards by the faceplates and edges only; avoid touching the printed circuit board and

connector pins.

y

Handle cards by the faceplates and edges only; avoid touching the printed circuit board and

connector pins.

y

Avoid contact between the cards and clothing. The wrist strap only protects the card from

ESD voltages on the body; ESD voltages on clothing can still cause damage.

y

For safety, periodically check the resistance value of the antistatic strap. The measurement

should be between 1 and 10 Mohms.


Installing and Servicing the System

y

Before installation, the power switch of the system should be turned OFF and disconnect all

power and external cables.

y

Remove all jewelry (including rings and chains) or other items that could get caught in the

system or heat up and cause serious burns.

y

Do not touch the backplane or mid-plane with your hand or metal tools.

y

Do not work alone under potentially hazardous conditions.

y

Do not perform any action that creates a potential hazard to people or makes the equipment

unsafe.
