Parts and Required Tools
Note Some parts and required tools described in this section are not available from Cisco Systems. The
grounding lug and associated screws are included with the accessory kit.
To make an adequate grounding connection, you will need the following parts and tools:
• Grounding lug—The grounding lug has two #10 AWG holes spaced 0.63 in center to center. A
Panduit LCDX6-10A-L or Pencom EL1033 lug may be used if the lug from the accessory kit has
been misplaced.
• Two M4 (metric) hex-head screws.
• One grounding wire (6 AWG recommended)—The length of the grounding wires depend s on the
location of your switch within the site and its proximity to proper grounding facilities.
• Number 2 Phillips screwdriver.
• Crimping tool—This tool must be large enough to accommodate the girth of the grounding lug whe n
you crimp the grounding cable into the lug.
• Wire-stripping tool.
Connecting System Ground and Power
This section describes how to connect the Catalyst 4500 E-series switches to earth ground. The system
ground connection is required if FXS modules are installed or if thi s equipment is installed in a US or
European Central Office.You must complete this procedure before connecting system power or turning
on your switch.
To attach the grounding lug and cable to the grounding pad on your Catalyst 4500 E-series switch,
perform the following steps:
Step 1 Using a wire-stripping tool, remove approximately 0.75 inches (19 mm) of the covering from the e nd of
the grounding wire.
Step 2 Insert the stripped end of the grounding wire into the open end of the grounding lug (Figure 3-3).
Step 3 Using a crimping tool, secure the grounding wire in place in the grounding lug.
Step 4 Locate the grounding pad on the switch. (See Figure 3-3).
