■ Power source
q Provide a power source within six feet (1.8 m) of the installation
location. This source must provide 100 VAC to 240 VAC, and 50
Hz to 60 Hz power. Power specifications for the switch are shown
in Appendix A, “Technical Specifications”.
q If multiple products are installed in the same rack system, the power
source must be capable of handling the entire load. The overall
system AC current load must not exceed 80 percent of the branch
circuit AC current rating.
q If power strips are used to connect multiple products, the load
should not exceed 80 percent of the power strip's marked electrical
current rating.
q Maintain reliable grounding of rack-mounted equipment. Give
special attention to power supply connections other than direct
connections to the branch circuit, such as power strips and other
power connector adapters.
q Primary voltage selection within the above ranges is automatic and
requires no user action.

WARNING: To reduce the risk of electric shock or damage to the
equipment:
■ Do not disable the power cord-grounding plug or use a three-to-two
pronged adapter at the outlet. 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.
■ Disconnect power from the unit by unplugging power cord from the
electrical outlet or from the back of the unit.
■ Do not place anything on power cords or cables. Arrange them so
that no one can accidentally step on or trip over them. Do not pull on a
cord or cable. When unplugging from the electrical outlet, grasp the
plug and pull if from the outlet. Do not pull the plug out by the cord.
■ Do not overload the AC supply branch circuit that provides power to
the rack. Consult the electrical authority having jurisdiction over your
facility wiring and installation requirements.
