3.5.3 Grounding the Switch

Check to determine if your local or national electrical codes require an external ground to all IT
components. If so, connect a ground wire to one of the casing screws and connect the other end to
a valid ground. If you choose to not use the ground screw, make sure that the rack is properly
grounded and that there is a valid ground connection between the chassis of the switch and the
rack. Test the ground using an Ohm meter.
Some national and/or local codes may require IT components to be bonded and exter-
nally grounded (not including the power cord ground). You must follow all national and
local codes when installing this equipment.

3.5.4 Power Connections and Initial Power On

The switch platform ships with one or two Power Supply Units. For switches with only one unit
installed, a second PSU may be installed at a later time. Each supply has a separate AC receptacle.
The input voltage is auto-adjusting for 100 - 240 VAC, 50-60Hz power connections. The power
cords should be standard 3-wire AC power cords including a safety ground and rated for 15A or
higher.
Caution: The switch platform will automatically power on when AC power is
applied. There is no power switch. Check all boards, power supplies, and fan
tray modules for proper insertion before plugging in a power cable.
Caution: After inserting a power cable and confirming the green system status
LED light is on; make sure that the Fan Status indicator shows green.
If the fan status indicator is not green then unplug the power connection and
check that the fan module is inserted properly and that the mating connector of
the fan unit is free of any dirt and/or obstacles.
Caution: When turning off the switch, make sure ALL LEDS are off to ensure
a powered down status.
