Starting the Switch
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.
Step 4
After you install the chassis, 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.
Starting the Switch
You start the switch by connecting it to its dedicated power source. If you need n+1 redundancy, you must
connect each of the power supplies to one or two power sources. If you need n+n redundancy, you must
connect each power supply in a switch to a different power source.
Before You Begin
• The switch must be installed and secured to a rack or cabinet.
• The switch must be adequately grounded.
• The rack must be close enough to the dedicated power source so that you can connect the switch to the
• You have the designated power cables for the power supplies that you are connecting to the dedicated
• The switch is not connected to the network (this includes any management or interface connections).
• The fan and power supply modules are fully secured in their chassis slots.
Step 1
For each AC power supply, do the following:
a) Using the recommended AC power cable for your country or region, connect one end to the AC power supply.
b) Connect the other end of the power cable to the AC power source.
Step 2
For each HVAC/HVDC power supply, connect it to a power source as follows:
a) Using the recommended high voltage power cable for your country or region, connect the Anderson Power Saf-D-Grid
connector on the power cable to the power receptacle on the power supply. Make sure that the connector clicks when
fully pushed into the receptacle.
b) Connect the other end of the power cable to a power source.
• When connecting to an HVAC power source, insert the C14 or LS-25 plug in a receptacle for the HVAC power
source.

power sources.
Depending on the outlet receptacle on your AC power distribution unit, you might need

an optional jumper power cord to connect the switch to your outlet receptacle.
All of the fan slots must be filled with fan modules and the power supply slots must be filled with the
same types of power supplies (do not mix AC and DC power supplies).
