Inserting the Grounding Wire in the Grounding Lug
Step 3
Use the crimping tool to crimp the lug to the grounding wire. Verify that the grounding wire is securely
attached to the ground lug by attempting to pull the wire out of the crimped lug.
Step 4
Remove the adhesive label from one of the power supply grounding pads, and secure the grounding wire
lug to the grounding pad threaded studs with two M6 nuts (tighten to a maximum of 40 in-lb [4.5 N·m]).
Figure 6-2
shows the location of the grounding pads on the front side of the power supply. Ensure that
the grounding lug and the grounding wire do not interfere with other switch hardware or rack equipment.
