Before you connect system power or turn on the Cisco SCE 8000 chassis, you must complete this procedure:
Step 1
Remove approximately 0.75 inch (19 mm) of the covering from the end of the grounding wire using a wire-stripping
tool.
Insert the stripped end of the grounding wire into the open end of the grounding lug.
Step 2
To secure the grounding wire in place in the grounding lug, use the manufacturer recommended crimping tool.
Step 3
Step 4
Locate and remove the adhesive label from the system grounding pad on the chassis (Figure 4).
