Step 3
Secure the grounding lug to the chassis grounding pad with two M4 screws, and tighten each screw to 11.5 to 15 in-lb
(1.3 to 1.7 N·m) of torque.
Step 4
Prepare the other end of the grounding wire and connect it to an appropriate grounding point in your site to ensure an
adequate earth ground for the switch. If the rack is fully bonded and grounded, connect the grounding wire as explained
in the documentation provided by the vendor for the rack.
Powering Up the Switch
To power up the switch, you must connect one or two power supplies to AC power sources. The number of
power supplies and power sources used depends on the following conditions:
• If you are using combined power (not using power redundancy), you must connect one power supply to
one AC power source.
• If you are using power supply (n+1) redundancy, you must connect two power supplies to one AC power
source.
• If you are using grid (n+n) redundancy, you must use two power supplies and two AC power sources—you
must connect each power supply to a different power source.
Before you begin
You must have the following before powering up the switch:
• Switch installed in a rack and connected to an earth ground
