Introduction

a Network Interface Card (NIC) that has WOL capability. Wake-On-LAN

must be enabled in BIOS. Note that Wake-On-Lan can only be used with an

ATX 2.01 (or above) compliant power supply.

1-6 Power Supply

As with all computer products, a stable power source is necessary for

proper and reliable operation. It is even more important for processors that

have high CPU clock rates.

The SUPER X5DP8-G2/X5DPE-G2/X5DPR-8G2+/X5DPR-iG2+/X5DPi-G2 ac-

commodates ATX power supplies. Although most power supplies generally

meet the specifications required by the CPU, some are inadequate. You

should use one that will supply at least 400W of power and includes the

additional +12V, 8-pin power connector - an even higher wattage power

supply is recommended for high-load configurations. Also your power sup-

ply must supply 1.5A for LAN1 and LAN2.

NOTE: Auxiliary 12v power (J15) is necessary to support Intel Xeon

CPUs. Failure to provide this extra power will result in the CPUs

becoming unstable after only a few minutes of operation. See

Section 2-5 for details on connecting the power supply cables.

It is strongly recommended that you use a high quality power supply that

meets ATX power supply Specification 2.02 or above. It must also be SSI

compliant (info at http://www.ssiforum.org/). Additionally, in areas where

noisy power transmission is present, you may choose to install a line filter

to shield the computer from noise. It is recommended that you also install a

power surge protector to help avoid problems caused by power surges.

1-7 Super I/O

The disk drive adapter functions of the Super I/O chip include a floppy disk

drive controller that is compatible with industry standard 82077/765, a data

separator, write pre-compensation circuitry, decode logic, data rate selec-

tion, a clock generator, drive interface control logic and interrupt and DMA

logic. The wide range of functions integrated onto the Super I/O greatly

reduces the number of components required for interfacing with floppy disk

drives. The Super I/O supports 360 K, 720 K, 1.2 M, 1.44 M or 2.88 M disk

drives and data transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s.It also

provides two high-speed, 16550 compatible serial communication ports
