Juniper Networks manual Connecting Earth Ground to an EX2200 or EX3200 Switch

Complete Hardware Guide for EX2200 Ethernet Switches

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 68

•Connecting Earth Ground to an EX4200 Switch on page 69

•Connecting Earth Ground to an EX4500 Switch on page 70

•Connecting Earth Ground to an EX8208 Switch on page 71

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” on page 47. 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: SomeearlymodelsofEX3200switchesrequire10-24x.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

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 25 on page 67.
