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 34 on page 83.
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.
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.
■ Washers and ¼-20x.5/8-in. screws to secure the grounding lug to the protective
earthing terminal
■ Phillips (+) screwdriver, number 2
