Notes on Use

On the Power Source

❑Your computer operates on 100V–120V AC 50/60 Hz only.
❑The total power draw of installed add-in cards must not exceed the
specifications for the power supply. Do not overload the system by installing
add-in cards that draw excessive current. The system is designed to provide 2
amps (average) of 5V power for each card in the system not to exceed a total
of 10 amps. The total from +5V current draw in a fully-loaded system (with
all the add-in card slots filled) must not exceed 10 amps. If you add
components to the system that draw current from the power supply, the
maximum combined +3.3V and +5V output must not exceed 70 watts.
❑Plug all the power cords for your computer and its peripheral equipment into
the same AC supply line. AC derived from different supply lines may result
in voltage differences that can cause unstable operation or unwanted weak
currents at the time of connection.
❑Do not share the AC outlet with any other power-consuming equipment,
such as copying machines or shredders.
❑You can purchase a power strip with a surge protector. This device prevents
damage to your computer caused by sudden power surges such as those that
may occur during an electrical storm.
❑If you live in an area that experiences frequent power fluctuations, you may
want to purchase an Uninterruptible Power Supply (UPS). This device
contains both a surge protector and a battery backup. The surge protector
prevents damage to your computer caused by power surges. The battery
backup safeguards your data during a brief period of power loss.
❑The power control button on the front panel does not turn off the system AC
power. To remove power from the system, you must shut down the computer
as described in the User Guide and then unplug the AC power cord from the
wall outlet or power strip.
❑Do not place heavy objects on the power cord.
❑Do not operate the system with the cover removed. Always reinstall the
cover before turning on the system.
❑To disconnect the cord, pull it out by the plug. Never pull the cord itself.
