Safety Instructions

Use the following safety guidelines to ensure your own personal

safety and to help protect your system from potential damage.

Throughout this safety section, the caution icon ( ) is used to

indicate cautions and precautions that you need to review and

follow.

Safety Cautions

To reduce the risk of bodily injury, electrical shock, fire, and

damage to the equipment, observe the following precautions.

Observe and follow service markings. Do not service any product

except as explained in your system documentation. Opening or

removing covers that are marked with the triangular symbol with a

lightning bolt may expose you to an electrical shock. Only a trained

service technician should service components inside these

compartments.

If any of the following conditions occur, unplug the product from

the electrical outlet and replace the part or contact your trained

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.

– The product does not operate correctly when you follow

the operating instructions.

• Keep your system 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

system gets wet, see the appropriate section in your

troubleshooting guide or contact your trained service

provider.

• Do not push any objects into the openings of your system.

Doing so can cause a fire or an electric 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:

– 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 attached devices are electrically rated to

operate 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 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 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 an 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 extension 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 company 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:

– 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.

• Move products with care; ensure that all casters and/or

stabilizers are firmly connected to the system. Avoid

sudden stops and uneven surfaces.

General Precautions for Rack-

Mountable Products

Observe the following precautions for rack stability and safety.

Also refer to the rack installation documentation accompanying the

system and the rack for specific caution statements and procedures.

Systems are considered to be components in a rack. Thus,

"component" refers to any system as well as to various peripherals

or supporting hardware.

CAUTION: Installing systems in a rack without the

front and side stabilizers installed could cause the

rack to tip over, potentially resulting in bodily injury

under certain circumstances. Therefore, always

install the stabilizers before installing components in

the rack.

After installing system/components in a rack, never

pull more than one component out of the rack on its

slide assemblies at one time. The weight of more

than one extended component could cause the rack

to tip over and may result in serious injury.

• Before working on the rack, make sure that the stabilizers

are secured to the rack, extended to the floor, and that the

full weight of the rack rests on the floor. Install front and

side stabilizers on a single rack or front stabilizers for

joined multiple racks before working on the rack.

Always load the rack from the bottom up, and load the heaviest

item in the rack first.

Make sure that the rack is level and stable before extending a

component from the rack.
