Attaching Your ESD Grounding Strap

Electrostatic discharge (ESD) damage, which can occur when modules or other FRUs are improperly

handled, results in intermittent or complete failures. Modules consist of printed circuit boards that are

fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral

components of the carrier. Although the metal carrier helps to protect the board from ESD, always use

an ESD grounding strap when handling modules.

Follow these guidelines for preventing ESD damage:

• Always use an ESD wrist strap and ensure that it makes maximum contact with bare skin. ESD

grounding straps are available with banana plugs, metal spring clips, or alligator clips. All

Catalyst 6500 series chassis are equipped with a banana plug connector (identified by the ground

symbol next to the connector) somewhere on the front panel. If you have an older Catalyst 6500

series chassis equipped with a plastic banana plug connector, we recommend that you use either the

supplied ESD grounding wrist strap (with a metal clip) or an ESD grounding wrist strap equipped

with an alligator clip. If you have a newer Catalyst 6500 series chassis that has a bare metal hole as

the banana plug connector (also identified by the ground symbol next to the connector), we

recommend that you use a personal ESD grounding strap equipped with a banana plug.

• If you choose to use the disposable ESD wrist strap supplied with most FRUs or an ESD wrist strap

equipped with an alligator clip, you must attach the system ground lug to the chassis in order to

provide a proper grounding point for the ESD wrist strap.

Note This system ground is also referred to as the network equipment building system (NEBS)

ground.
