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 EX4500 Switch
The protective earthing terminal is located on the left rear of the chassis in an EX4500
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
EX4500 Switch.
NOTE: If you plan to mount your switch on four posts of a rack or cabinet, mount your
switch in the rack or cabinet before attaching the grounding lug to the switch. See
Mounting an EX4500 Switch on Four Posts in a Rack or Cabinet
Ensure that you have the following parts and tools available:
• Grounding cable for your EX4500 switch—The grounding cable must be 14 AWG
(2 mm²), minimum 90°C wire, or as permitted by the local code.
• Grounding lug for your grounding cable. See Grounding Cable and Lug Specifications
for EX4500 Switches.
