Note In all situations, grounding practices must comply with local National Electric Code (NEC) requirements or local laws and regulations.
Note Always ensure that all of the modules are completely installed and that the captive installation screws are fully tightened. In addition, ensure that all I/O cables and power cords are properly seated. These practices are normal installation practices and must be followed in all installations.
Preventing Electrostatic Discharge Damage
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.
For preventing 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 chassis from the Cisco Nexus 6000 series are equipped with a banana plug connector (identified by the ground symbol next to the connector) somewhere on the front panel. 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.
