Electromagnetic noise problems are
not anticipated, but installing a
grounding system in a new building
is often the least expensive route
and the best way to plan for the
future. Best grounding
recommendations should be
followed as closely as possible.

Electromagnetic noise problems are
not anticipated, but installing a
grounding system is always
recommended. Best grounding
recommendations should be
followed as much as possible.

noise or man-made industrial noise.

office environment.
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.
Note
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when modules or other devices 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 Cisco
UCS 6300 Series Fabric Interconnect 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 field-replaceable units 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.
