Safety Cautions

To greatly reduce the risk of physical injury, electrical shock, fire, and damage to equipment, observe the following
precautions.
Observe and follow service markings.
• Do not attempt to service any product, except when it is explained in the system's documentation.
• Opening or removing covers that are marked with this (
• 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 immediately and replace the part or
contact your trained service provider:
• Damage to the power cable, extension cable, or plug.
• 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 the operating instructions are correctly followed.
General safety cautions:
• Keep the system away from radiators and heat sources. Also, do not block cooling vents.
• Do not spill food or liquids on system components, and never operate the product in a wet environment. If the
system gets wet contact your trained service provider.
• Do not push any objects into the openings of the system. Doing so can cause fire or electric shock by shorting out
interior components.
• Only use this product with approved equipment.
• Allow the product to cool before removing the cover or touching internal components.
• Operate the product only from the type of external power source indicated on the electrical ratings label. If unsure of
the type of power source required, consult your service provider or local power company.
• 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 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 using an extension cable is necessary, use a 3-wire cable with
properly grounded plugs.
• Observe the 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 the 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 or national wiring rules.
When connecting or disconnecting power to and from 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 system has multiple sources of power, disconnect power from the system by unplugging all power cables from
the power supplies.
• Move products with care and ensure that all casters and stabilizers are firmly connected to the system. Avoid
sudden stops and uneven surfaces.
To help avoid damage to the system, be sure that the voltage selection switch, on the power supply, is set to match the
power available at the switch's location:
