Operating instructions

• Do not operate the equipment within a separate enclosure unless adequate intake and
exhaust ventilation are provided on the enclosure that adhere to the guidelines listed
above.
• Do not restrict airflow into the equipment by blocking any vents or air intakes.
• Avoid placing loose papers underneath your equipment.
• Do not push any objects into the air vents or openings of your equipment. Doing so can
cause fire or electric shock by shorting out interior components.
• Do not use your equipment in a wet environment, for example, near a bath tub, sink, or
swimming pool or in a wet basement.
• Use only approved power cable(s). If you have not been provided with a power cable
for the equipment or for any AC-powered option intended for the equipment, purchase a
power cable that is approved for use in your country. The power cable must be rated for
the equipment and for the voltage and current marked on the equipment’s electrical
ratings label. The voltage and current rating of the cable should be greater than the ratings
marked on the equipment.
• To help prevent electric shock, plug the equipment and peripheral power cables into
properly grounded electrical outlets. These cables are equipped with three-prong plugs to
help ensure proper grounding. Do not use adapter plugs or remove the grounding prong
from a cable. If you must use an extension cable, use a 3-wire cable with properly
grounded plugs.
• Observe extension cable and power strip ratings. Ensure that the total ampere rating of
all equipment plugged into the extension cable or power strip does not exceed 80 percent
of the ampere ratings limit for the extension cable or power strip.
• To help protect your equipment from sudden, transient increases and decreases in
electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply
(UPS).
• Position equipment cables and power cables carefully; route cables so that they cannot
be stepped on or tripped over. Be sure that nothing rests on any cables.
• Do not modify power cables or plugs. Consult a licensed electrician or your power
company for site modifications. Always follow your local/national wiring rules.
• When connecting or disconnecting power to hot-pluggable power supplies observe the
following guidelines:
• Install the power supply before connecting the power cable to the power
supply.
• Unplug the power cable before removing the power supply.
• If the equipment has multiple sources of power, disconnect power from
the system by unplugging all power cables from the power supplies.
