•
Use only approved power cables. If you have not been provided with a power
cable for your IP/TV server 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 cord, use a three-wire cord with properly grounded plugs.
•
Observe extension cord and power strip ratings. Make sure that the total
ampere rating of all products plugged into the extension cord or power strip
does not exceed 80 percent of the extension cord or power strip ampere
ratings limit.
•
Do not use appliance or voltage converters or kits sold for appliances with
your product.
•
To help protect your system components from sudden, transient increases and
decreases in electrical power, use a surge suppressor, line conditioner, or
uninterruptible power supply (UPS).
•
Position cables and power cords carefully; route cables and the power cord
and plug so that they cannot be stepped on or tripped over. Be sure that
nothing rests on your system components’ cables or power cord.
•
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.
System Reliability Considerations
To help ensure proper cooling and system reliability, make sure of the following
points:
•
Each of the drive bays has either a drive or a filler panel installed.
•
Each of the power-supply bays has a power supply or a power supply filler
panel installed.
