There are two protective earthing terminals on an EX8216 switch: one on the left side of
the chassis and the other on the rear of the chassis. Only one of the two protective earthing
terminals needs to be permanently connected to earth ground.
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 EX8216 switch—The grounding cable must be 2 AWG
(33.6 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.
