Using an ESD Wrist Strap to Prevent ESD Damage

Before you touch any switch modules, you must ground yourself to protect the modules from electrostatic
discharge (ESD). You can ground yourself by wearing an ESD wrist strap connected to a grounded chassis
or a grounded rack.
Caution Always handle modules by their carrier edges (typically the covered bottom, sides, and front of the module)
and never touch the circuitry on the module.
Before you begin
You must have a grounding connection close to where you are installing components in the chassis.
Step 1
Attach or wrap an ESD wrist strap to your arm.
