2 Grounding cable, with 0.75 in. (19 mm) of insulation
stripped from one end, inserted into the grounding
lug and crimped in place

Step 3

Secure the grounding lug to the chassis grounding pad with two M4 screws (see Callouts 1 and 3 in the previous figure),
and tighten the screws to 11 to 15 in-lb (1.24 to 1.69 N·m) of torque.

Powering Up the Switch

To power up the switch, you must connect the power supplies to one or two power sources. The number of
power sources used depends on the type of power redundancy that you require as follows:
• For no power redundancy, connect only the power supplies to one power source.
• For n+1 redundancy, connect the power supplies to one or two power sources.
• For n+n redundancy, connect each power supply to a different power source (two power sources required).
