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.

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: SomeearlymodelsofEX3200switchesrequire10-24x.25-in. screwsratherthan 10-32x.25-in. screws. If the Juniper Networks product number on the label next to the protectiveearthingterminalisfrom750-021xxxthrough750-030xxx,theswitchrequires 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 64 on page 167.
