Preventing ESD Damage

ESD damage occurs when electronic modules or components are improperly handled and can result in complete or intermittent failures. To prevent ESD damage, follow these guidelines:

Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
When handling modules or coming into contact with any internal components, always use a wrist strap connected to one of the following:
- Captive installation screws on an installed module or power supply
- ESD wrist strap connector (see Figure B-1 through Figure B-4 for connector locations on the Catalyst 5000 series switches)

Note Catalyst 5002 switch—The AC-input chassis is shown in Figure B-1 (with 155W power supply) and Figure B-2 (with 175W power supply with PFC). On the Catalyst 5002 DC-input chassis, the ESD wrist strap connector is located on the left-hand side.

Any unpainted surface on the chassis

Handle modules by the edges only.
Avoid contact between the modules and clothing. The wrist strap protects only the module from ESD voltages on the body; ESD voltages on clothing can still cause damage.
After removing a supervisor engine or switching module, place it on an antistatic surface or in a static-shielding bag. If you plan to return the module to the factory, immediately place it in a static-shielding bag.

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