FCC Statement on Class B

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 and, if not installed

and used in accordance with the instruction manual, 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, the user is encouraged to try

to correct the interference by one or more of the following measures:

•Reorient or relocate the receiving antenna.

•Increase the separation between the equipment and the receiver.

•Connect the equipment into an outlet on a circuit different from that to

which the receiver is connected.

•Consult the dealer or an experienced radio TV technician for help.

Notice:

1.The changes or modifications not expressly approved by the party

responsible for compliance could void the user's authority to operate the

equipment.

2.Shielded interface cables must be used in order to comply with the

emission limits.

Caution:

Danger of explosion if battery incorrectly replaced.

Replace only with the same or equivalent type recommended by the manufacturer.

Dispose of used batteries according to the manufacturer’s instructions.

The manufacturer makes no warranties with respect to this documentation and

disclaims any implied warranties of merchantability, quality, or fitness for any

particular purpose. The information in this document is subject to change

The 686IPK is an Intel PentiumII processor based system board using

Intel’s high performance 233MHz Pentium®II processor with 512KB ex-

ternal L2 cache, 233MHz Pentium®II processor with 256KB external L2

cache or 266MHz Pentium®II processor with 512KB external L2 cache.

The 686IPK supports processor fan “failure detection” function that

monitors the status of the processor fan. It detects any irregularity in

processor fan RPM (Rotation Per Minute) and alerts you to attend to

any problem that may damage your system. The “failure detection” cir-

cuit requires a processor fan that operates at greater than 3600 RPM.

The 686IPK is equipped with a switching voltage regulator that auto-

matically detects 1.8V to 3.5V. The VID (Voltage Identifications) code

found in a processor allows the 686IPK to detect and adjust to the re-

quired voltage.

The 686IPK system board can support 8MB to 512MB of system

memory. It is equipped with 4 SIMM sockets allowing you to install x32

or x36 EDO or fast page mode SIMMs. The x36 SIMM supports parity

checking which informs the user of memory failure and prevents error

accumulation.

The 686IPK system board is designed to fit into an ATX form factor

case. Using an ATX power supply, you can either shut down your com-

puter by pressing the Power button located on the front bezel of your

computer or by executing the Shut Down command under the

Windows 95 operating system. Your system will enter the “soft power

off” state. With a modem installed, you can power on your system to

remotely transmit or access data. An ATX power supply also provides

adequate airflow throughout the chassis to prevent overheating the pro-

cessor.

Chapter 2

Hardware Installation

This chapter summarizes the steps to install the 686IPK system board

into your system unit. It also includes a description of the area in which

you must work and directions for processor and memory installation.

Before installing the system board, carefully read the Installing the Sys-

tem Board section for proper installation procedures.

Preparing the Area

Before unpacking the system board, make sure the location you have

selected is relatively free of dust and static electricity. Excessive expo-

sure to dust, static electricity, direct sunlight, excessive humidity, ex-

treme cold, and water can damage the operational capabilities of your

system board. Place the system board on a workbench (not in a chas-

sis). Avoid placing the unit on surfaces such as carpeted floors. These

areas also attract static electricity which can damage some circuits on

your system board.

Make sure the power source has a properly grounded, three-pronged

socket. It is essential that the power connection be properly grounded

for correct functioning of your system board. For further protection, we

recommend that you use a surge suppressor. This will protect the sys-

tem board from damage that may result from a power surge on the

electrical line.

Move items that generate magnetic fields away from your system board

since magnetic fields can also damage your system board. Once you

have selected the ideal location, unpack the 686IPK system board care-

fully.

Handling the System Board

It is quite easy to inadvertently damage your system board even before

installing it in your system unit. Static electrical discharge can damage

computer components without causing any signs of physical damage.

You must take extra care in handling the system board to ensure

against electrostatic build-up.

Static Electricity Precautions

1.To prevent electrostatic build-up, leave the board in its anti-static

bag until you are ready to install it.

2.Wear an antistatic wrist strap.

3.Do all preparation work on a static-free surface with the system

board components facing up.

4.Hold the system board by its edges only. Be careful not to touch

any of the components, contacts or connections, especially gold

contacts, on the board.

5.Avoid touching the pins or contacts on all modules and connectors.

Hold modules and connectors by their ends.

Warning:

Electrostatic discharge (ESD) can damage your processor, disk drives,

add-in boards, and other components. Perform the upgrade instruction

procedures described at an ESD workstation only. If such a station is

not available, you can provide some ESD protection by wearing an anti-

static wrist strap and attaching it to a metal part of the system chassis.

If a wrist strap is unavailable, establish and maintain contact with the

system chassis throughout any procedures requiring ESD protection.

Installing the System Board

If you are installing the 686IPK system board, the following outlines the

basic installation steps. Before installing the system board into your sys-

tem unit, you should prepare the tools you will need.

You will need:

•One medium size, flat-bladed screwdriver

•One medium Phillips screwdriver

•One needle-nosed pliers

•One small nutdriver

1.Unlock your system unit. Turn off the power and disconnect all

power cords and cables.

2.Remove the system unit cover. Refer to the manufacturer’s instruc-

tions if necessary.

3.Detach all connectors from the old system board and remove ex-

pansion cards seated in any expansion slots.

4.Loosen the screws holding the original system board and remove

the board from the system. Save the screws.

5.Remove the 686IPK from its original packing box. Be careful to

avoid touching all connectors and pins on the board. Refer to the

handling instructions on pages 8-9 for proper handling techniques.

6.Place the system board on a flat surface (not in a chassis) with the

component side facing up.

7.Install the retention mechanism that comes with the package. Refer

to the Installing the Retention Mechanism section for installation in-

structions.

8.You are now ready to install the Intel PentiumII processor. Before

you install the processor, carefully read the installation instructions

under the Intel PentiumII Processor Installation section.

Note:

Make sure the system board is not yet installed with any SIMMs,

add-in cards, cables, etc.

9.Insert the memory modules into the memory banks on the 686IPK. The

quantity and location of the memory modules depends on the

memory configuration and type of modules you intend to use.

10.Set the corresponding jumpers.

11.Install the prepared 686IPK system board into the case. Make sure

you install screws into the four mounting holes shown on the next

page.
