any commercial electrical equipment vendor.
•
Two grounding wires—It is recommended that you use 4 AWG, 0.204-inch (5.18-mm)
diameter wire for grounding purposes. However, you may use a grounding wire of
smaller gauge. The actual wire diameter and length depend on your router location and
the installation environment.

Number 2 Phillips head screwdriver.
•
A 1/4-inch flat-blade screwdriver (to loosen/tighten the captive installation screws at the
bottom of the rear access cover of the router)

Crimping tool—This tool must be large enough to accommodate the girth of the
grounding lug when you crimp the grounding cable into the lug.
•
Wire stripping tool.
To attach the grounding lug and cable to the grounding receptacle on the Cisco 12008,
perform the following steps:
Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the
Step 1
covering from the end of the grounding wire.
Step 2
Insert the stripped end of the grounding wire into the open end of the grounding
lug.
Step 3
Use the crimping tool to secure the grounding wire in place in the grounding lug.
Step 4
Using a 1/4-inch flat-blade screwdriver, remove the rear access cover of the
router. To do so, loosen the two captive installation screws at the bottom of the
cover; pivot the cover up and away from the router to release the three access
cover tabs from their slots. Set the access cover aside temporarily.
Locate the grounding receptacle on the side panel of the router (see Figure 3-18).
