I. Introduction
Features
I. Introduction
• 1-3. Features
AP8000 is a corporate server configured on the XG-DLS smart mother-
board which uses the 440GX chipset from Intel and supports two Pentium®
III/II XeonTM processors and 100MHz front side bus in order to handle
even the most complicated server tasks.The following are highlights to this
server’s many features. For additional features and details, read the mother-
board User’s Manual included with this server package.

I. Introduction
Safeguards
I. Introduction
• 1-4. Safeguards
Observe the following safety instructions any time you are connecting or
disconnecting any devices.
Operation Safety
Tools Required
A Phillips (cross) screwdriver and a standard (flat) screwdriver are needed
to install or remove the components in this server.
IMPORTANT
• Any operation on this server must be conducted by certified
or experienced persons.
• Before operating your server, carefully read all the manuals
included with the server package.
• Before using the server, make sure all cables are correctly
connected and the power cables are not damaged. If anydam-
age is detected, contact your dealer as soon as possible.
• To avoid short circuits, keep paper clips, screws, and staples
away from connectors, slots, sockets and circuitry.
• Before opening the chassis panels, make sure all power cables
are unplugged.
• Avoid dust, humidity, and temperature extremes. Place the
server on a stable surface.
• If the power supply is broken, do not try to fix it by yourself.
Contact an authorized dealer.
• It is recommanded that you wear gloves when assembling or
dissembling the server to protect from cuts and scrapes.
• When the server is powered on, heat sinks and the surfaces
of certain IC devices may be hot. Do not touch them. Check
whether the fans are functioning properly.

I. Introduction
Electrical Safety
I. Introduction
• 1-5. Electrical Safety
IMPORTANT
• Before installing or removing signal cables, ensure that the
power cables for the system unit and all attached devices are
unplugged.
•To prevent electrical shock hazard, disconnect the power cable
from the electrical outlet before relocating the system.
• When adding or removing any additional devices to or from
the system, ensure that the power cables for those devices are
unplugged before the signal cables are connected. If possible,
disconnect all power cables from the existing system before
you add a device.
• Use one hand, when possible, to connect or disconnect signal
cables to prevent a possible shock from touching two sur-
faces with different electrical potentials.
Static-Sensitive Devices
Motherboards, adapters, and disk drives are sensitive to static
electricity discharge. These devices are wrapped in antistatic
bags to prevent this damage. Take the following precautions:
• If you have an antistatic wrist strap available, use it while
handling the device.
• Do not remove the device from the antistatic bag until you
are ready to install the device in the system unit.
• With the device still in its antistatic bag, touch it to a metal
frame of the system.
• Grasp cards and boards by the edges. Hold drives by the
frame. Avoid touching the solder joints or pins.
• If you need to lay the device down while it is out of the
antistatic bag, lay it on the antistatic bag. Before picking it
up again, touch the antistatic bag and the metal frame of the
system unit at the same time.
• Handle the devices carefully in order to prevent permanent
damage.
IMPORTANT
This product is equipped with a three-wire power cable and plug
for the user’s safety. Use the power cable in conjunction with a
properly grounded electrical outlet to avoid electrical shock.

• 3-1. Starting the Server
Turn ON the server by turning the power knob clockwise and pushing in-
wards momentarily. The power button will snap back when released be-
cause ATX power systems have an electrical ON/OFF switch unlike AT
systems which require a permanent ON or OFF position. If the Power On
LED does not light, make sure the power cord is connected to the system
unit and to a working grounded outlet.

AP8000 Hardware Reference Guide16
III. Basic Operation
IMPORTANT
The power switch only turns off DC power (power supply output).
To turn offAC power (power supply input), you need to unplug the
electrical cords from the redundant power supply.
This server does not come with any pre-installed software. When booting
your server for the first time, make BIOS settings by following the mother-
board User’s Manual.
• 3-2. LED Indicators
The LED indicators are located on the top-left edge of the front panel. The
Power LED lights when the motherboard receives power from the power
supply. Activity LED lights when there is activity from IDE or SCSI de-
vices connected to the motherboard. Fan #1-5 lights if the corresponding
fan stops turning.
When installing Windows NT 4.0, use the Windows NT installation
disks. Installing from the CD will require you to pre-install SCSI driv-
ers by pressing F6 before setup begins. You may need device drivers
on a floppy disk in order to install devices during the Windows NT
4.0 setup. To use the onboard SCSI, you will need to copy Adaptec’s
SCSI driver (from the provided support CD) onto a floppy disk
(“Winnt”, “Disk1”, “Txtsetup.oem”).
