Cisco Systems 3550 Manual De Usuario

For switches that require a two-hole lug for grounding, you can order a kit containing the ground lug and 
hardware from Cisco. For the Catalyst 3550-12G, 3550-24, and 3550-24-FX switches, order part number 
NEBS-LUG-3550=.

When you install the ground-lug kit, you cannot connect an RPS to the switch.

To install the ground lug, you need these tools and equipment:

Ratcheting torque screwdriver with a Phillips head that exerts up to 15 pound-force inches (lbf-in.) 
or 240 ounce-force inches (ozf-in.) of pressure

Panduit crimping tool with optional controlled-cycle mechanism (model CT-700, CT-720, CT-920, 
CT-920CH, CT-930, or CT-940CH)

6-gauge copper ground wire (insulated or noninsulated)

Wire-stripping tool for stripping 6-gauge wires

The illustrations in this section show the Catalyst 3550-12T switch as an example. Follow the same 
procedure to install the ground lug on the Catalyst 3550-24 and 3550-24-FX switches.

To ground the switch to earth ground, follow these steps. Make sure to follow any grounding 
requirements at your site.

Use the two Phillips pan-head screws to attach the RPS connector cover to the back of the switch as 
shown in 

If your ground wire is insulated, use a wire stripping tool to strip the 6-gauge ground wire to 0.5 
inch (12.7 mm) ± 0.02 inch (0.5 mm). (See 

.)

Slide the open end of the ground lug over the exposed area of the 6-gauge wire.

Using a Panduit crimping tool, crimp the ground lug to the 6-gauge wire. (See 

Use the two number-10-32 screws to attach the ground lug and wire assembly to the switch rear panel 
RPS connector cover, as shown in
