Safety instructions
Observe the follo wing safety instructions w hen using y our system:
Foll ow all instructions marked on t he system and in the
•
documentation.
When the computer is turned off, a small amount of electric al
•
current still runs through the computer . Al wa ys unplug the
computer from the electrical outl et before cleaning t he system or
opening the computer co ver. (Follo w the cle aning instructions in
your user’s guide.)
Do not use this product near w ater or a heat sourc e, such as a
•
radiator or heat registe r .
Do not spill anything on or into the system. The best wa y to a v oid
•
spills is to av oid eating and dr inking near y our system.
Make sure you set up the system on a stab le w ork surface.
•
Openings in the computer cabinet are pro vided for ventilat ion. Do
•
not block or co ver these openings. Mak e sure you pro v ide adequate
space (at least 12 inches) ar ound the system for v entilation w hen
you set up y our w ork area. Ne ver insert object s of any kind into the
computer ventilation sl ots.
Use the voltage set ting for y our area. The v oltage sel ector swit ch is
•
set at the factory to the correct voltage.
Warning!
Do not attempt to service
the system yourself except
as explained elsewhere in
the system documentation.
Adjust only those controls
covered in the instructions.
Opening or removing
covers marked “Do Not
Remove” may expose y ou
to dangerous electrical
voltages or other risks.
Refer all servicing of those
compartments to qualified
service personnel.
As a safety feature, this syste m is equipped with a 3-wir e po w er
•
cord to ensure that the product i s properl y grounded when in use.
The plug will only fit into a grounding-type outlet. If you are
unable to insert the plug into a n outlet, contact an ele ctrician to
install the appropriate out let.
Do not walk on the po w er cord or allow anything to rest on it.
•
If you use an extensi on cord with this system, mak e sure the total
•
ampere ratings on the products plugged into the extens ion cord do
not exceed the extension cord ampere r ating. Also, the total ampere
requirements for all products pl ugged into the w all outlet must not
exceed 15 amperes.
Preface vii
There is a danger of explosion if the CMOS (complementary
•
metal-oxide semiconductor ) battery is replaced incorrectl y.
Replace the battery with the same or equiv alent type recommended
by the manufacturer . Dis pose of used batteries according to the
manufacturer’s instructions.
Unplug the system from the w all outlet and ref er servicing to

qualified personnel if:
• The pow er cord or plug i s damaged.
• Liquid has been spilled into the s ystem.
• The system does not operate properl y w hen the operating

Caution!
Prevent electrostatic
damage to your system by
following static electricity
precautions every time you
open your computer case.
Warning!
To avoid exposure to
dangerous electrical
voltages and moving parts,
turn off your computer and
unplug the power cord
before removing the system
cover.
Static electricity precautions
Static electricity can permanentl y damage electroni c components in your
computer . When opening your compute r case, al wa ys perform the
following pr ocedure:
1.
Wear a grounding wrist strap (ava ilable at most electronics stores).
2.
T urn off the system po wer .
3.
T ouch the b ack of the po w er suppl y fan, located on the back of t he
case, to discharge an y static el ectricity.
4.
Unplug all pow er cords from A C outlets.
5.
Remove the computer case co v er .
Foll ow these precautions t o av oid electrost atic damage to y our system
components:
Avoid static-causing surfaces s uch as plastic an d styrofoam in y our
•
work area.
Remov e the parts from their antis tatic bags onl y when you are
•
ready to use them. Do not la y parts on the outside of anti static bags
since only the insi de of the bag pro vides ant istatic protecti on.
Alw ays hold cards b y their edges and their metal mounting brack et.
•
Avoid touching components on the cards and the ed ge connectors
that connect to expansion slots.
Never slide cards or other parts o ver any s urface.

System jumpers
These jumpers allo w you to set c ertain characteristics of the system. Some
jumpers are reserved and are not descr ibed in this section. Do not change
any jumper unless it i s necessary to configure the system. In some cases,
changing the settings of reserved j umpers can cause damage to t he system
board. For instructions on setting the jumpers on t he system board , see
“Setting system board jumpers” on pa ge 32.
SHM mode jumper (J)
This jumper indicates whet her the system is a tower unit or rack mounted.
The system hardware manager (SHM) sof tware checks this jumper to
determine the characteristics of the s ystem.
Clear CMOS jumper (Z)
This jumper allo ws you to clea r the CMOS memory . You should only do
this if you cannot access t he normal methods of modifying the CMOS and
modifications to the CMOS are necessary. Cl earing CMOS memory
returns all BIOS Setup settings to the default v alues.
Processor speed setting jumper (BB)
This jumper allo ws you to set the spe ed of the processor. Both processors,
in dual processor configurations, must have the same speed rating. If
processors of dif ferent speeds are used i n the same system, the processor s
must run at the speed of the slo w er processor.
