Step 5 Use the two number-10-32 screws to attach the ground lug and wire assembly to the rear panel of the switch.

Step 6 Using a ratcheting torque screwdriver, torque each ground-lug screw to 15 lbf-in. (240 ounce-force inches [ozf-in.]). Figure C-3shows how to torque the ground screws on a Cisco ME DC switch.
