1-3 Special Features

Recovery from AC Power Loss

Basic I/O System (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 press the power

switch to turn it back on), or for it to automatically return to a power-on state. See

the Advanced BIOS Setup section to change this setting. The default setting is

Last State.

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the board. All have

an onboard System Hardware Monitoring chip that supports PC health monitoring.

An onboard voltage monitor will scan these onboard voltages continuously: Vcore,

BAT, 3.3V, 3VSB, 5V, 12V, VTT CPU, DIMM. Once a voltage becomes unstable, a

warning is given, or an error message is sent to the screen. The user can adjust

the voltage thresholds to dene the sensitivity of the voltage monitor.

Fan Status Monitor with Firmware Control

PC health monitoring in the BIOS can check the RPM status of the cooling fans. The

onboard CPU and chassis fans are controlled by Thermal Management via BIOS

(under the Hardware Monitoring section in the Advanced Setting).

Environmental Temperature Control

The thermal control sensor monitors the CPU temperature in real time and will turn

on the thermal control fan whenever the CPU temperature exceeds a user-dened

threshold. The overheat circuitry runs independently from the CPU. Once the ther-

mal sensor detects that the CPU temperature is too high, it will automatically turn

on the thermal fans to prevent the CPU from overheating. The onboard chassis

thermal circuitry can monitor the overall system temperature and alert the user when

the chassis temperature is too high.

Note: To avoid possible system overheating, please be sure to provide

adequate airow to your system.

System Resource Alert

This feature is available when the system is used with Supero Doctor III in

the Windows OS environment or used with Supero Doctor II in Linux. Supero

Chapter 1: Introduction

1-11

Doctor is used to notify the user of certain system events. For example, you can

also congure Supero Doctor to provide you with warnings when the system

temperature, CPU temperatures, voltages and fan speeds go beyond predened

thresholds.

1-5 ACPI Features

ACPI stands for Advanced Conguration and Power Interface. The ACPI specica-

tion denes a exible and abstract hardware interface that provides a standard

way to integrate power management features throughout a PC system, including

its hardware, operating system and application software. This enables the system

to automatically turn on and off peripherals such as CD-ROMs, network cards, hard

disk drives and printers.

In addition to enabling operating system-directed power management, ACPI also

provides a generic system event mechanism for Plug and Play, and an operating

system-independent interface for conguration control. ACPI leverages the Plug and

Play BIOS data structures, while providing a processor architecture-independent

implementation that is compatible with Windows XP, Windows Vista, and Windows

2008 Operating Systems.

Slow Blinking LED for Suspend-State Indicator

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

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.

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.

This motherboard accommodates 24-pin ATX power supplies. Although most

power supplies generally meet the specications required by the CPU, some are

inadequate. In addition, the 12V 8-pin power connector located at JPW2 is also

required to ensure adequate power supply to the system. Also your power supply

must supply 1.5A for the Ethernet ports.

Note: Please use a power supply that contains a 24-pin and a 8-pin power

connectors. Be sure to connect these connectors to the 24-pin (JPW1) and

the 4-pin (JPW2) power connectors on the motherboard.

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

power supply Specication 2.02 or above. It must also be SSI compliant. (For more

1-12

C7B75 User’s Manual

information, please refer to the web site at http://www.ssiforum.org/). Additionally, 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.

1-7 Super I/O

The Super I/O supports two high-speed, 16550 compatible serial communication

ports (UARTs). 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 an SMI or SCI function pin. It also features auto power management

to reduce power consumption.

2-1 Static-Sensitive Devices

Electrostatic-Discharge (ESD) can damage electronic com ponents. To avoid dam-

aging your system board, it is important to handle it very carefully. The following

measures 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 your computer chassis provides excellent

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

the motherboard.

• Use only the correct type of onboard CMOS battery. Do not install the onboard

battery upside down to avoid possible explosion.

Unpacking

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

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

2-2 Processor and Heatsink Installation

Warning: When handling the processor package, avoid placing direct

pressure on the label area of the fan.

Important:

Always connect the power cable last, and always remove it before adding,

removing or changing any hardware components. Make sure that you in-

stall the processor into the CPU socket before you install the CPU heatsink.

If you buy a CPU separately, make sure that you use an Intel-certied

multi-directional heatsink only.

Make sure to install the system board into the chassis before you install

the CPU heatsink.

When receiving a server board without a processor pre-installed, make

sure that the plastic CPU socket cap is in place and none of the socket

pins are bent; otherwise, contact your retailer immediately.

Refer to the Supermicro website for updates on CPU support.
