Chapter 3 Installing the Switch
Connecting Source Power to the Chassis
To attach the grounding lug and cable to the grounding pad, follow these steps:
Step 1
If you are using insulated wire, use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of
the covering from the end of the grounding wire. If you are using bare wire, go to Step 2.
Step 2
Insert the stripped end of the grounding wire into the open end of the grounding lug.
Step 3
Crimp the grounding wire in the barrel of the grounding lug. Verify that the ground wire is securely
attached to the ground lug.
Step 4
Place the grounding wire lug against the grounding pad, making sure that there is solid metal-to-metal
contact.
Step 5
Secure the grounding lug to the chassis with two M4 screws. (See
Figure 3-4
.) Ensure that the grounding
lug and the grounding wire do not interfere with other switch hardware or rack equipment.
Step 6
Prepare the other end of the grounding wire, and connect it to an appropriate grounding point in your
site to ensure adequate earth ground for the switch.
