SUPER MICRO Computer X6DHE-G2, X6DH8-G2 manual Power Supply, Super I/O

Chapter 1: Introduction

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 X6DH8-G2/X6DHE-G2 can only accommodates 24-pin ATX power sup- plies. Although most power supplies generally meet the specifications re- quired by the CPU, some are inadequate. You should use one that will supply at least 400W of power connector. In addition, the 12V 4-pin power supply (J32) - is also required to ensure adequate power supply to the system. Also your power supply must supply 1.5A for the Ethernet ports.

NOTE: The + 12V 8-pin Aux. Power Connector (J1D1) is also required to support Intel Xeon CPUs. Failure to provide this extra power will result in CPU PWR Failure. See Section 2-5 for details on connect- ing the power supply.

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 (UARTs), one of which supports serial infrared communication. Each UART includes a 16-byte send/receive FIFO, a programmable baud rate generator,
