Connecting Earth Ground to an EX8208 Switch
The protective earthing terminal is located on the left side of the chassis in an EX8208
switch.
An AC-powered EX Series switch chassis gets additional grounding when you plug the
power supply in the switch into a grounded AC power outlet by using an AC power cord
appropriate for your geographical location. See AC Power Cord Specifications for an
EX8200 Switch.
Ensure that you have the following parts and tools available:
•
Grounding cable for your EX8208 switch—The grounding cable must be 6 AWG
(13.3 mm²), minimum 60°C wire, or as permitted by the local code.
•
Grounding lug for your grounding cable. See Grounding Cable and Lug Specifications
for EX8200 Switches.
