Power Requirements

Your system requires a clean, steady power source for reliable performance of the high frequency CPU on
the SPC-8450-LVA , 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 card 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 the SPC-8450-LVA in
order to set up a workable system.

Installation procedure

(1) Confirm the power supply is off.
(2) Install the processor with correct orientation.
(3) Insert the DRAM module with correct orientation.
(4) Mount the Fan on the top of the processor and connect it to FAN2 connector.
(5) Insert +12V Power supply cable to PW1 connector.
(6) The jumpers are set up according to the conditions to be used.
(7) Insert all external cables (Hard disk, floppy, keyboard, Mouse, LAN, etc.)
(8) Insert CRT or LCD monitor to DVI-I connector (CN4).
(9) Turn on the power.
(10)Enter the BIOS setup mode by pressing ‘Del’ key during boot up.
(11)Use the “Load BIOS Optimal Defaults” feature.
(12)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-8450-LVA supports a single Intel 478pin FC-PGA2 type, Pentium 4, Celeron or Celeron D
processor. The processor’s VID pins automatically program the voltage regulator on the CPU card to the
required processor voltage. The host bus speed is automatically selected. The processor connects to the
CPU card through the 478-pins socket.

The CPU card supports the processors listed in table below:

Celeron Processor

Host Bus frequency

400MHz

Celeron D Processor

Host Bus frequency

533MHz

Pentium 4 Processor

Host Bus frequency

400MHz / 533MHz

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

After you have installed the processor into the socket 478, check if the configuration setup for the CPU
type and speed are correct. The CPU should always have a Heat Sink and a cooling fan attached to
prevent overheating.

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: CN13

The SPC-8450-LVA provides a bus-mastering PCI IDE interface. This interface support PIO Mode 3,
PIO Mode 4, ATAPI devices (e.g., CD-ROM), 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
board, 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.

3. Hardware Installations

Front Panel Connector: CN17

This header can be connected to a front panel power switch. The front panel connector includes headers
for these I/O connections:

Power Button:
When the ATX power supply is used, this header connects power supply ON button.

Power LED:
This header is connected with a LED when turning on power to the computer.

Reset Button:
This header connects the reset button.

HDD LED:
This header is connected with a LED shown while being reading the data of the IDE hard disk drive or

writing it.

Speaker:
An external speaker can be installed in this CPU board as an option. When the computer cannot use the

video interface, the speaker offers the error warning sound in POST. Moreover, because this speaker is
not connected with the audio subsystem, it is not possible to sound it by the output from the audio
subsystem.
