SUPER MICRO Computer X6DHi-G2 Power Supply, Super I/O, External Modem Ring-On, Wake-On-LAN WOL

X6DH3-G2/X6DHi-G2 User's Manual

External Modem Ring-On

Wake-up events can be triggered by a device such as the external modem ringing when the system is in the SoftOff state. Note that external modem ring-on can only be used with an ATX 2.01 (or above) compliant power supply.

Wake-On-LAN (WOL)

Wake-On-LAN is defi ned as the ability of a management application to remotely power up a computer that is powered off. Remote PC setup, up-dates and asset tracking can occur after hours and on weekends so that daily LAN traffi c is kept to a minimum and users are not interrupted. The motherboard has a 3-pin header (WOL) to con- nect to the 3-pin header on 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 X6DH3-G2/X6DHi-G2 accommodates ATX 24-pin power supplies. Although most power supplies generally meet the specifi cations required by the CPU, some are inadequate. You should use one that will supply at least 400W of power. Your power supply must supply 1.5A for the Ethernet ports. The +12V, 4-pin power connector (J38) is required to ensure adequate power supply to the system. Additionally, you should also use the onboard 12V 8-pin power connector (J1D1) to support Intel Xeon CPUs. Failure to provide this extra power will result in instability of the CPU after only a few minutes of operation. See Section 2-5 for details on connecting the power supply.

It is strongly recommended that you use a high quality power supply that meets ATX power supply Specifi cation 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 fi lter 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 fl oppy disk drive controller that is compatible with industry standard 82077/765, a data separator, write pre-compensation circuitry, decode logic, data rate selection, a clock genera- tor, 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 fl oppy disk drives. The Super I/O supports 360 K, 720K,
