Connecting Earth Ground to an EX2200 or EX3200 Switch

CAUTION: Using a grounding cable with an incorrectly attached lug can
damage the switch.
Follow the procedure that applies to your switch:
Connecting Earth Ground to an EX2200 or EX3200 Switch on page 164
Connecting Earth Ground to an EX4200 Switch on page 165
Connecting Earth Ground to an EX4500 Switch on page 166

Connecting Earth Ground to an EX8216 Switch on page 168
The protective earthing terminal is located on the rear of the chassis in an EX2200 switch
and in an EX3200 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. For EX2200 switches, see AC Power Cord
Specifications for EX2200 Switches. For EX3200 switches, see AC Power Cord
Specifications for EX3200 Switches.
Ensure that you have the following parts and tools available:
Grounding cable for your switch—The grounding cable must be minimum 14 AWG
(2 mm²), minimum 90°C wire, or as permitted by the local code.
Grounding lug for your grounding cable—The grounding lug required is a Panduit
LCD6-14BH-L or equivalent.
Washers and 10-32x.25-in. screws to secure the grounding lug to the protective earthing
terminal
NOTE: Some early models of EX3200 switches require 10-24x.25-in. screws
rather than 10-32x.25-in. screws. If the Juniper Networks product number
on the label next to the protective earthing terminal is from 750-021xxx
through 750-030xxx, the switch requires 10-24x.25-in. screws.
Phillips (+) screwdriver, number 2
