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 142
•
Connecting Earth Ground to an EX4200 Switch on page 143
•
Connecting Earth Ground to an EX4500 Switch on page 144
•
Connecting Earth Ground to an EX8208 Switch on page 145
•
Connecting Earth Ground to an EX8216 Switch on page 146
Connecting Earth Ground to an EX2200 or EX3200 Switch
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 and EX4200 Switches” on page 102.
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: Someearlymodels of EX3200 switches require10-24x.25-in.screwsratherthan
10-32x.25-in. screws. If the Juniper Networks product number on the label next to the
protectiveearthingterminalis from 750-021xxx through 750-030xxx, the switchrequires
10-24x.25-in. screws.
•
Phillips (+) screwdriver, number 2
To connect earth ground to an EX2200 or EX3200 switch:
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 52 on page 141.
