Installing a Cisco 12008 3-39
Connecting System Ground
These grounding lugs are not available from Cisco Systems; they are common items that
can be obtained from any electrical equipment vendor, such as Panduit.
•Four Phillips head, M6 (metric) machine screws with locking washers and nuts—This
mounting hardware is not available from Cisco Systems; it can be obtained readily from
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.
This grounding wire is not available from Cisco Systems; it is commonly av ailable fro m
commercial cable vendors.
•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 Cisco12008,
perform the following steps:
Step1 Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the
covering from the end of the grounding wire.
Step2 Insert the stripped end of the grounding wire into the open end of the grounding
lug.
Step3 Use the crimping tool to secure the grounding wire in place in the grounding lug.
Step4 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.
Step5 Locate the grounding receptacle on the side panel of the router (see Figure3-18).
