Dell PowerConnect J-Series J-EX8216 Ethernet Switch Hardware Guide 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 a J-EX8216 Switch on page 130 Connecting Earth Ground to a J-EX8216 Switch There are two protective earthing terminals on a J-EX8216 switch: one on the left side of the chassis and the other on the rear of the chassis. Only one of the two protective earthing terminals needs to be permanently connected to earth ground. An AC-powered J-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 a J-EX8200 Switch" on page 83. Ensure that you have the following parts and tools available: • Grounding cable for your J-EX8216 switch-The grounding cable must be 2 AWG (33.6 mm²), minimum 60°C wire, or as permitted by the local code. • Grounding lug for your grounding cable. See "Grounding Cable and Lug Specifications for J-EX8200 Switches" on page 59. • Washers and ¼-20x.5/8-in. screws to secure the grounding lug to the protective earthing terminal • Phillips (+) screwdriver, number 2 To connect earth ground to a J-EX8216 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 57 on page 129. 3. Secure the grounding lug to the protective earthing terminal with screws. 4.
