Chapter 3 Installing the Switch

Connecting the System Ground

To attach the grounding lug and cable to the grounding pad, follow these steps:
Step 1 Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the covering from the end of
the grounding wire.
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 Locate and remove the adhesive label from the system grounding pad on the switch. The location of the
system grounding pad differs among Catalyst 6500 series chassis. Refer to the figures listed to locate the
system grounding pad on your chassis.

The system (NEBS) ground serves as the primary safety ground for the Catalyst 6503 and
Caution
Catalyst 6503-E chassis that are equipped with DC-input power supplies. You must install the system
(NEBS) ground before you attach the source DC power cables to the DC PEM. If the Catalyst 6503 or
Catalyst 6503-E chassis are already powered up, we recommend that you remove the source DC from
the Catalyst 6503 and Catalyst 6503-E chassis before attaching the system (NEBS) ground.

Place the grounding wire lug against the grounding pad, making sure that there is solid metal-to-metal
Step 5
contact.
Note
Secure the grounding lug to the chassis with two M4 screws. Ensure that the grounding lug and the
Step 6
grounding wire will not interfere with other switch hardware or rack equipment.
Prepare the other end of the grounding wire, and connect it to an appropriate grounding point in your
Step 7
site to ensure adequate earth ground for the switch.

There are two system grounding pads on the Catalyst 6509-NEB-A switch chassis. One pad is
located in the upper-left corner of the chassis, and the other is located in the upper-right corner
of the chassis. Additionally, both system grounding pads have 3 M4 screw holes so that the
system grounding lug can be installed either horizontally or vertically.
