CAUTION: To reduce the risk of damage to the equipment, verify that all AC voltage
selector switches are set to match your local AC line voltage (115V or 230V). If the
AC voltage selector switches are not properly set, your components will be damaged
when power is supplied.
5. After all cables and power cords have been routed to their power destinations,
connect the power cords to a main power switch such as a properly rated Power
Distribution Unit (PDU).
NOTE: If you are not using a PDU, route the power cord directly to a properly rated and
grounded AC wall or floor outlet.

Do not disable the power cord grounding plug. The grounding plug is an
important safety feature.
Plug the power cord into a grounded (earthed) electrical outlet that is easily
accessible at all times.
When using an optional power distribution device, make sure that the
ground integrity is maintained for each connection by plugging each
component into a reliable grounded outlet.
