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.
