3.2.1 Grounding
Grounding is a safety measure to direct excess electric charge to the ground. It prevents damage to
the Switch, and protects you from electrocution. Use the grounding screw on the rear panel and the
ground wire of the AC power supply to ground the Switch.
The grounding terminal and AC power ground where you install the Switch must follow your country’s
regulations. Qualified service personnel must ensure the building’s protective earthing terminals are
valid terminals.
Installation of Ethernet cables must be separate from AC power lines. To avoid electric surge and
electromagnetic interference, use a different electrical conduit or raceway (tube/trough or enclosed
conduit for protecting electric wiring) that is 15 cm apart, or as specified by your country’s electrical
regulations.
Any device that is located outdoors and connected to this product must be properly grounded and
surge protected. To the extent permissible by your country’s applicable law, failure to follow these
guidelines could result in damage to your Switch which may not be covered by its warranty.
Note: The specification for surge or ESD protection assumes that the Switch is properly
grounded.
1
Remove the M4 ground screw from the Switch’s rear panel.
2
Secure a green or yellow ground cable (16 AWG or smaller) to the Switch's rear panel using the M4
ground screw.
