Introduction

The SUPER X5DPA-TGM/X5DPA-TGM+ accommodates 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

350W of power and includes the additional +12V, 8-pin power connector -

an even higher wattage power supply is recommended for high-load con-

figurations. Also your power supply must supply 1.5A for LAN1 and LAN2.

(*NOTES:

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

(UARTs), one of which supports serial infrared communication. Each UART

includes a 16-byte send/receive FIFO, a programmable baud rate generator,

complete modem control capability and a processor interrupt system.

Each UART includes a 16-byte send/receive FIFO, a programmable baud

rate generator, complete modem control capability and a processor inter-

rupt system. Both UARTs provide legacy speed with baud rate of up to

115.2 Kbps as well as an advanced speed with baud rates of 250 K, 500 K,

or 1 Mb/s, which support higher speed modems.
