Grounding the Switch
Proper Grounding Practices
Grounding is one of the most important parts of equipment installation. Proper grounding practices
ensure that the buildings and the installed equipment within them have low-impedance connections and
low-voltage differentials between chassis. When you properly ground systems during installation, you
reduce or prevent shock hazards, equipment damage due to transients, and data corruption.
