Cisco Systems 4900M manual Site Planning Checklist, Preventing Electrostatic Discharge Damage

Chapter 2 Site Planning

Site Planning Checklist

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

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage occurs when electronic cards or components are improperly handled and can result in complete or intermittent failures. Follow these guidelines to prevent ESD damage:

•Always use an ESD-preventive wrist or ankle strap, and ensure that it makes maximum contact with the skin.

•When coming into contact with any internal components, always use a wrist strap connected to one of the following:

–ESD wrist strap connector

–Any unpainted grounded surface on the chassis or equipment rack

Caution Periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).

•Handle cards by the edges only.

•Avoid contact between the modules and clothing. The wrist strap protects only the card from ESD voltages on the body; ESD voltages on clothing can still cause damage.

Site Planning Checklist

Table 2-1lists the site planning activities that you should perform before you install the Catalyst 4900M switch. Completing each activity helps to ensure a successful switch installation.
