FCC/DOC Compliance
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a residential installation. This equipment generates, uses, and can radiate radio frequency
energy. If the equipment is not installed and used in accordance with the instructions, it may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a particular
installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, try to correct the interference as follows: reorient or relocate the affected device; increase
the separation between this equipment and the affected device; connect this equipment to an outlet on a circuit different
from the circuit to which the affected device is connected; consult a dealer or an experienced radio/television
technician for help.
This Class B digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations.
Cet appareil numérique de la classe B respecte toutes les exigencies du Règlement sur le materiél brouilleur du Canada.

Safety Notices
Service and upgrade tasks should be performed by users who can follow instructions in a manual to service equipment,
and can do so without harm to themselves or damage to the equipment.
To reduce the risk of electrical shock and energy hazards, do not attempt to open the equipment unless instructed, and
do not use a tool for purposes other than instructed.
Internal components may be at high temperatures. Allow time for them to cool before handling them.
Internal components can be damaged by static electricity. Use an antistatic wrist strap connected to the bare metal of
the system’s chassis to protect against electrostatic discharge.
Notes
Changes or modifications made to the system that are not approved by the party responsible for compliance could void
the user's authority to operate the equipment.
Procedures in this document assume familiarity with the general terminology associated with personal computers, and
with the safety practices and regulatory compliance required for using and modifying electronic equipment.
Read all operating instructions before using this device. Keep these instructions for future reference. Follow all
warnings on the device or in the operating instructions.

2 Components
This chapter locates and describes major components on the system board. The chapter also
provides information on the integrated controllers and hardware monitoring.
WARNING Before touching the system board or its components, disconnect the system’s
power cord from its AC power outlet.
WARNING System board components may be at high temperatures. Allow time for them
to cool before handling them.
WARNING System board components can be damaged by static electricity. Use an
antistatic wrist strap connected to the bare metal of the system’s chassis to
protect against electrostatic discharge.
Processors
The system board contains two Intel SC242 (Slot 1) processor sockets. Each socket has an
associated voltage regulator integrated on the system board.
Primary Processor Socket
Secondary Processor Socket

8
Each processor socket accepts an Intel Pentium III processor (100 MHz or 133 MHz front-side
bus). The processor is secured to the socket by retention clips on both sides. The retention clips
are secured by nuts to screws attached to the system board.
The system can function with one or two processors installed. For a single-processor system, a
processor bus terminator card must be installed in the unused processor socket. For a dual-
processor system, both processors must be the same speed.

Memory Modules
The system board includes sockets for up to six PC133 or eight PC100 dual inline memory
modules (DIMMs). The memory speed matches the system board’s front-side bus speed.
Memory module sockets are organized into four banks (Bank 0 through Bank 3) of two sockets
each that use two-way memory interleaving.
Bank 3
Bank 2
Bank 1
Bank 0

10
Each socket accepts a 168-pin registered Synchronous Dynamic RAM (SDRAM) DIMM. Each
DIMM has a 128-bit memory width and 16-bit error correcting code (ECC) protection.
Each socket is keyed for proper DIMM insertion. Release tabs on each end of the socket capture
the DIMM and secure it in the socket.

Bank 0

11
On system boards with a 133 MHz front-side bus (FSB), DIMM terminator modules are installed
in Bank 1 instead of standard DIMMs.
To avoid damaging a DIMM and voiding its warranty, take the following precautions:
♦Do not remove the DIMM from its antistatic package until you are ready to install it.
♦Do not touch the metallic finger contacts.
♦Do not bend, twist, drop, or otherwise handle the DIMM carelessly.
♦Do not expose the DIMM to moisture or extreme temperatures.
When adding or replacing system memory on all system boards:
♦On a 100 MHz FSB system board, install DIMMs in order from the lowest bank to the highest
bank, starting with bank 0.
♦On a 133 MHz FSB system board, install DIMMs first in Bank 3, then in Bank 2, and finally
in Bank 0. Do not install DIMMs in Bank 1.
♦On a 133 MHz FSB system board, do not replace DIMM terminator modules in Bank 1 with
standard DIMMs.
♦Ensure all installed DIMMs are PC133 (133 MHz FSB system board) or PC100 (100 MHz
FSB system board), as appropriate. Do not mix DIMMs of different speeds.
♦Use only registered DIMMs. Do not use unbuffered DIMMs.
♦Install DIMMs in both sockets of a bank. Do not install only one DIMM in a bank.
♦Install the same size DIMM in both sockets of a bank. You can vary DIMM sizes from bank
to bank, but not within a bank.
