1. Connect one end of the grounding cable to a proper earth ground, such as the rack
in which the switch is mounted.
2. Place the grounding lug attached to the grounding cable over the protective earthing
terminal. See Figure 64 on page 167.
3. Secure the grounding lug to the protective earthing terminal with screws.
4. Dress the grounding cable and ensure that it does not touch or block access to other
switch components and that it does not drape where people could trip over it.
Connecting Earth Ground to an EX8216 Switch
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” on page 112.
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” on page 87.
• Washers and ¼-20x.5/8-in. screws to secure the grounding lug to the protective earthing
terminal
• Phillips (+) screwdriver, number 2
To connect earth ground to an EX8216 switch:
