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, this product is designed to operate with at least a 200 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.
(3) Mount the Heat sink on the top of the processor. (The heat sink with a fan connects a fan cable to the
fan connector on a board.)
(4) Insert the DDR DRAM module with correct orientation.
(5) Confirm this product into to PICMG back plane.
(6) Insert all external cables. (Keyboard, Mouse, LAN, etc.)
(7) Prepare a CRT monitor for CMOS setup.
(8) Turn on the power.
(9) Enter the BIOS setup mode by pressing ‘F2’ key during boot up.
(10)Use the “Load BIOS Optimal 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.
CPU Installation:
This product supports a single Intel Celeron M or Pentium M processor (FSB 400MHz). 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 socket-478 comes with 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.
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.
Refer to the description of optional heat sink fan appending for attachment of a heat sink fan.
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.
