Grounding the Switch
To ground the switch to earth ground, follow these steps. Make sure to follow any
grounding requirements at your site.
Step 1 Locate the ground lug and the two number-10-32 screws. The ground lug and
screws are on the rear panel of the Catalyst 2950G-24-EI-DC switch or on the
front panel of the Catalyst 2950ST-24 LRE 997 switch.
Use a standard Phillips screwdriver or a ratcheting torque screwdriver with a
Phillips head. Set the screws and the ground lug aside.
Step 2 If your ground wire is insulated, use a wire stripping tool to strip the 6-gauge
ground wire to 0.5 inch (12.7 millimeter [mm]) ± 0.02 inch (0.5 mm) as shown in
Figure C-1.
