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.

Power Connections and Initial Power On
The switch platform ships with one or two power supply units. Each supply has a separate AC
receptacle. The input voltage is auto-adjusting for 100 - 240VAC, 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.
Figure 27: Status LEDs 5 Minutes After Power On
Warning: Any yellow or red status LEDs are cause for concern and must be dealt
with immediately.
It can take up to 5 minutes to boot up, during which time the status LED may indicate
red.
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.
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.
