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.

Connecting Source Power to the Chassis
This section provides instructions on connecting source power to the chassis. Two procedures are
provided:
• Connecting Source DC to the DC-Input Power Supply, page 3-10
• Connecting Source AC to the AC-Input Power Supply, page 3-11
Note The ME6524 switches support mixing AC-input and DC-input power supplies in the same chassis.
