Installing the Optional Ground Kit
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=.
Note 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
Note 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.
Step 1 Use the two Phillips pan-head screws to attach the RPS connector cover to the
back of the switch as shown in Figure 3-16.
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 mm) ± 0.02 inch (0.5 mm). (See Figure C-1 on
page C-3.)
Step 3 Slide the open end of the ground lug over the exposed area of the 6-gauge wire.
