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 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 fire or 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.

Safety Instructions (continued)

•

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 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.
