Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when FRUs are improperly handled, results in intermittent or complete failures.

To prevent ESD damage, follow these guidelines:

•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 Cisco ME 6524 Ethernet switch chassis are equipped with an ESD connector (identified by the ground symbol next to the connector) on the front panel.

•If you choose to use an ESD wrist strap equipped with an alligator clip, you must attach the system ground lug to the chassis 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.

•If your chassis does not have the system ground attached, you must install the system ground lug.

Note You do not need to attach a supplemental system ground wire to the system ground lug; the lug provides a direct path to the bare metal of the chassis.
