frequency, or selecting a high CPU V-Core voltage, memory voltage, chipset volt-

age, ICH chipset voltage, or an FSB termination voltage may cause the system

to become unstable. If this occurs, reset the setting to the default setting. In ad-

dition, extra fans may be needed for proper system cooling. The PDSLA/PDSLE

offers the option of overclocking; however, Supermicro is not responsible for any

damage caused by the use of overclocking.

PDSLA/PDSLE User’s Manual

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the PDSLA/PDSLE.

The motherboard has an onboard System Hardware Monitor chip that supports

PC health monitoring.

Recovery from AC Power Loss

BIOS provides a setting for you to determine how the system will respond when

AC power is lost and then restored to the system. You can choose for the system

to remain powered off (in which case you must hit the power switch to turn it back

on) or for it to automatically return to a power on state. See the Power Lost Control

setting in the BIOS chapter of this manual to change this setting. The default set-

ting is Last State.

Onboard Voltage Monitoring

The onboard voltage monitor will scan the following voltages continuously: CPU

Core, Chipset Core +1.5V, +3.3V, +3.3V standby, +5V, +5V Standby, Vbat and

±12V. Once a voltage becomes unstable, it will give a warning or send an error

message to the screen. Users can adjust the voltage thresholds to dene the sen-

sitivity of the voltage monitor by using SD III.

Fan Status Monitor with Software

The PC health monitor can check the RPM status of the cooling fans via Supero

Doctor III.

Fan Fail Alert

When a fan fails during the normal operation, the Fan Fail LED will start to blink

and the buzzer will be activated to indicate a fan failure.

CPU Overheat LED and Control

This feature is available when the user enables CPU overheat warning in the BIOS.

This allows the user to dene an overheat temperature. When this temperature

reaches the pre-dened overheat threshold, the CPU thermal trip feature will be

activated and it will send a signal to the Speaker LED and, at the same time, the

CPU will slow down.

Chapter 1: Introduction

1-11

1-4 PowerCongurationSettings

This section describes the features of your motherboard

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start blinking

to indicate that the CPU is in suspend mode. When the user presses any key, the

CPU will wake-up and the LED will automatically stop blinking and remain on.

BIOS Support for USB Keyboard

If the USB keyboard is the only keyboard in the system, the keyboard will function

like a normal keyboard during system boot-up.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a system

suspend button. When the user presses the power button, the system will enter

a SoftOff state. The monitor will be suspended and the hard drive will spin down.

Pressing the power button again will cause the whole system to wake-up. During the

SoftOff state, the ATX power supply provides power to keep the required circuitry

in the system "alive". In case the system malfunctions and you want to turn off the

power, just press and hold the power button for 4 seconds. The power will turn off

and no power will be provided to the motherboard.

Wake-On-Ring (WOR) Header

Wake-up events can be triggered by a device such as an 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.

1-5 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 of 1 GHz and faster.

1-12

PDSLA/PDSLE User’s Manual

The PDSLA/PDSLE accommodates 12V ATX power supplies. Although

most power supplies generally meet the specications required by the CPU, some

are inadequate. A 2-Amp of current supply on a 5V Standby rail is strongly recom-

mended.

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

12V ATX power supply Specication 1.1 or above. It is also required that the 12V

4-pin power connection (J41) be used for high-load congurations. In areas where

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

1-6 Super I/O

The disk drive adapter functions of the Super I/O chip include a 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 oppy disk drives. The Super I/O supports two 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. 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.

The Super I/O provides functions that comply with ACPI (Advanced Conguration

and Power Interface), which includes support of legacy and ACPI power manage-

ment through a SMI or SCI function pin. It also features auto power management

to reduce power consumption.

The IRQs, DMAs and I/O space resources of the Super I/O can be exibly adjusted

to meet ISA PnP requirements, which support ACPI and APM (Advanced Power

Management).

2-1 Electro-Static Sensitive Devices

Electro-Static Discharge (ESD) can damage electronic com ponents. To prevent

damage done to your system board, it is important to handle it very carefully. The

following steps are generally sufcient to protect your equipment from ESD.

Precautions

• Use a grounded wrist strap designed to prevent static discharge.

• Touch a grounded metal object before removing the board from the antistatic

bag.

• Handle the board by its edges only; do not touch its components, peripheral

chips, memory modules or gold contacts.

• When handling chips or modules, avoid touching their pins.

• Put the motherboard and peripherals back into their antistatic bags when not in

use.

• For grounding purposes, make sure that your computer chassis provides excel-

lent conductivity between the power supply, the case, the mounting fasteners

and the motherboard.

• Use only the correct type of CMOS onboard battery as specied by the Manufac-

turer. Do not install the CMOS onboard battery upside down to avoid a possible

explosion.

Unpacking

The motherboard is shipped in antistatic packaging to avoid static damage. When

unpacking the board, make sure the person handling it is static protected.

Installation Procedures

Follow the procedures listed below to install the motherboard into a chassis:

1. Install the processor and the heatsink to the motherboard.

2. Install the motherboard in the chassis.

3. Install the memory modules and add-on cards.

4. Finally, connect cables and install the drivers.

Caution: Please do not use a force greater than 8 lb/inch on each mounting screw

during motherboard installation.
