During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly
touch the backplane with your hand or any metal tool, or you could shock yourself.

Warning
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage may occur when modules or other FRUs are improperly handled, and
result in intermittent or complete failure of the modules or FRUs. Modules consist of printed circuit boards
that are fixed in metal carriers. EMI shielding and connectors are integral components of a carrier. Although
the metal carrier helps to protect the board from ESD, always use an ESD-grounding strap when handling
modules. To prevent ESD damage, follow these guidelines:
•
Always use an ESD wrist strap and ensure that it has maximum contact with bare skin. ESD grounding
straps are available with banana plugs, metal spring clips, or alligator clips. The chassis is equipped with
a banana plug connector (identified by the ground symbol next to the connector) on the front panel.
•
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.

Establishing System Ground
To attach the grounding lug and cable to the grounding pad, perform these steps
Before You Begin
To connect the system ground, you require the following tools and materials:
•
Grounding lug
—
A two-hole right-angled lug. Supports up to 6 AWG wire. Supplied as part of accessory
kit.
•
Grounding screws
—
Two M4 x 8 mm (metric) pan-head screws. Supplied as part of the accessory kit.
•
Grounding wire
—
Not supplied as part of accessory kit. The grounding wire should be sized according
to local and national installation requirements. Depending on the power supply and system, a 12 to 6
AWG copper conductor is required for U.S. installations. Commercially available 6-AWG wire is
recommended. The length of the grounding wire depends on the proximity of the switch to proper
grounding facilities.
