In all situations, grounding practices must comply with local National Electric Code (NEC)
Note
requirements or local laws and regulations.
Always ensure that all of the modules are completely installed and that the captive installation screws
Note
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:
•

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

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
After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:
Attach the ESD wrist strap to bare skin as follows:

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 Nexus 5000 Series chassis 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.
If your chassis does not have the system ground attached, you must install the system ground lug.
See
"Establishing the System Ground" section on page 2-14
location of the chassis system ground pads.
If you are using the ESD wrist strap supplied with the FRUs, open the wrist strap package and
unwrap the ESD wrist strap. Place the black conductive loop over your wrist and tighten the strap
so that it makes good contact with your bare skin.
If you are using an ESD wrist strap equipped with an alligator clip, open the package and remove
the ESD wrist strap. Locate the end of the wrist strap that attaches to your body and secure it to your
bare skin.
