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
