Power Management Features

- Support both ACPI (Advanced Configuration and Power Interface) and legacy (APM) power
management.

- ACPI v2.0 compliant

- APM v1.2 compliant

- PCI bus clock run, Power Management Enable (PME) control, all with hardware automatic wake-up.

- Multiple suspend power plane controls and suspend status indicators

- Normal, doze, sleep, suspend and conserve modes

- Global and local device power control

Power Requirements

Your system requires a clean, steady power source for reliable performance of the high frequency CPU,
the quality of the power supply is even more important. For the best performance makes sure your
power supply provides a range of 4.75 volts minimum to 5.25 volts maximum DC power source.

Power Consumption

For typical configurations, the CPU board is designed to operate with at least a 250 W power supply. A
higher-wattage power supply should be used for heavily-loaded configurations. The power supply must
meet the following requirements:

- Rise time for power supply: 2 ms - 20 ms

- Minimum delay for reset to Power Good: 100 ms

- Minimum Power down warning: 1 ms

The following table lists the power supply’s tolerances for DC voltages:

3. Hardware Installations

This chapter provides information on how to use the jumpers and connectors on this product in order to
set up a workable system.

Installation procedure

(1) Confirm the power supply is off.
(2) Install the processor with correct orientation. (only SPC-8520-LA)
(3) Install the fan on top of the processor and connect it to the CNJI connector.

(Only SPC-8520-LA)
(4) Insert the DRAM module with correct orientation.
(5) The jumpers are set up according to the conditions to be used.
(6) Insert all external cables (Hard disk, floppy, keyboard, Mouse, LAN, etc.)
(7) Insert the monitor to the analog RGB connector (CNV1).
(8) Turn on the power.
(9) Enter the BIOS setup mode by pressing ‘Del’ key during boot up.
(10) Use the “Load BIOS Optimized Defaults” feature.
(11) Configure the Peripheral Setup and the Standard Setup correctly.

CAUTION

The CMOS memory may be in an undefined state at power-on after a period of no battery backup.

3. Hardware Installations

CPU Installation

The SPC-8520-LA supports a single Intel(R) Celeron M or Pentium M processor (FSB 400MHz). The
processor’s VID pins automatically program the voltage regulator on the CPU board to the required
processor voltage. The host bus speed is automatically selected. The processor connects to the CPU
board through the 478-pins socket.

The socket-478 contains a turn lock to secure the processor. Make sure the notch on the corner of the
CPU corresponds with the notch on the inside of the socket.

The CPU should always have a Heat Sink and a cooling fan attached to prevent overheating.
Refer to the user’s guide of optional heat sink fan appending for attachment of a heat sink fan.
(The user’s manual for the optional heat sink fan [HSF-PM] is available on the CD-ROM attached to this

product.)

CAUTION

Ensure that the CPU heat sink and the CPU top surface are in total contact to avoid CPU overheating
problem that would cause your system to hang or be unstable.

3. Hardware Installations

Primary IDE Connector: CNI1

This product provides a bus-mastering PCI IDE interface. This interface support PIO Mode 3, PIO
Mode 4, ATAPI devices (e.g., CD-ROM drive), and Ultra DMA/33/66/100 synchronous- DMA mode
transfers. The BIOS supports logical block addressing (LBA) and extended cylinder head sector
(ECHS) translation modes. The BIOS automatically detects the IDE device transfer rate and translation
mode.

This connector supports the provided IDE hard disk ribbon cable. After connecting the single end to the
product, connect the two plugs at the other end to your hard disk(s). If you install two hard disks, you
must configure the second drive to Slave mode by setting its jumper accordingly. Please refer to your
hard disk documentation for the jumper setting.
