Do not push any objects into the openings of your system. Doing so can cause fire or elec-
tric shock by shorting out interior components.
Use the product only with approved equipment.
Allow the product to cool before removing covers or touching internal components.
Operate the product only from the type of external power source indicated on the electrical
ratings label. If you are not sure of the type of power source required, consult your service
provider or local power company.
To help avoid damaging your system, be sure the voltage selection switch (if provided) on
the power supply is set to match the power available at your location:
Also, be sure that attached devices are electrically rated to operate with the power avail-
able in your location.
Use only approved power cable(s). If you have not been provided with a power cable for
your system or for any AC powered option intended for your system, purchase a power
cable that is approved for use in your country. The power cable must be rated for the prod-
uct and for the voltage and current marked on the product's electrical ratings label. The
voltage and current rating of the cable should be greater than the ratings marked on the
product.
To help prevent electric shock, plug the system 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 exten-
sion cable, use a 3-wire cable with properly grounded plugs.
Observe extension cable and power strip ratings. Make sure that the total ampere rating of
all products 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 system from sudden, transient increases and decreases in electrical
power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS).
Position system 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 com-
pany for site modifications.
Always follow your local/national wiring rules.
When connecting or disconnecting power to hot-pluggable power supplies, if offered with
your system, observe the following guidelines:
Move products with care; ensure that all casters and/or stabilizers are firmly connected to
the system. Avoid sudden stops and uneven surfaces.
115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern coun-
tries such as South Korea and Taiwan
100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
230 V/50 Hz in most of Europe, the Middle East, and the Far East
Install the power supply before connecting the power cable to the power supply.
Unplug the power cable before removing the power supply.
If the system has multiple sources of power, disconnect power from the system by unplugging
all power cables from the power supplies.
