To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment,
observe the following precautions.
*HQHUDO3UHFDXWLRQV
bserve the following general precautions for using and working with your system:
bserve and follow service markings. Do not service any Dell product except as
explained in your Dell system documentation. pening or removing covers that
are marked with the triangular symbol with a lightning bolt may expose you to
electrical shock. Components inside these compartments should be serviced
only by a Dell authorized service technician.
If any of the following conditions occur, unplug the product from the electrical
outlet and replace the part or contact your Dell authorized service provider:
 The power cable, extension cable, or plug is damaged.
 An object has fallen into the product.
 The product has been exposed to water.
 The product has been dropped or damaged.

vii
 The product does not operate correctly when you follow the operating
instructions.
Keep your system components away from radiators and heat sources. Also, do
not block cooling vents.
Do not spill food or liquids on your system components, and never operate the
product in a wet environment. If the computer gets wet, see the appropriate
chapter in your troubleshooting guide or contact a Dell-authorized service
provider.
Do not push any objects into the openings of your system components. Doing so
can cause fire or electric shock by shorting out interior components.
Use the product only with Dell products or other Dell-approved equipment.
Allow the product to cool before removing covers or touching internal
components.
Use the correct external power source. perate the product only from the type
of power source indicated on the electrical ratings label. If you are not sure of the
type of power source required, consult your Dell service provider or local power
company.
To help avoid damaging your system components, be sure the voltage selection
switch (if provided) on the power supply is set to match the power available at
your location:
 115 volts (V)/60 hertz (Hz) in most of North and South America and some Far
Eastern countries 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
Also be sure that your monitor and attached devices are electrically rated to oper-
ate with the power available in your location.
Use only approved power cable(s). If you have not been provided with a power
cable for your server, storage system, or appliance, 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 product 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/components 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 three-wire cable with properly grounded plugs.
bserve 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 extension cable or power strip ampere ratings
limit.
