Gigabyte GA-78LMT-S2P: Chapter 1 Hardware Installation

Chapter 1 Hardware Installation

1-1 Installation Precautions

The motherboard contains numerous delicate electronic circuits and components which can

become damaged as a result of electrostatic discharge (ESD). Prior to installation, carefully read

the user's manual and follow these procedures:

Prior to installation, do not remove or break motherboard S/N (Serial Number) sticker or •

warranty sticker provided by your dealer. These stickers are required for warranty validation.

Always remove the AC power by unplugging the power cord from the power outlet before •

installing or removing the motherboard or other hardware components.

When connecting hardware components to the internal connectors on the motherboard, •

make sure they are connected tightly and securely.

When handling the motherboard, avoid touching any metal leads or connectors. •

It is best to wear an electrostatic discharge (ESD) wrist strap when handling electronic com- •

ponents such as a motherboard, CPU or memory. If you do not have an ESD wrist strap,

keep your hands dry and rst touch a metal object to eliminate static electricity.

Prior to installing the motherboard, please have it on top of an antistatic pad or within an •

electrostatic shielding container.

Before unplugging the power supply cable from the motherboard, make sure the power sup- •

ply has been turned off.

Before turning on the power, make sure the power supply voltage has been set according to •

the local voltage standard.

Before using the product, please verify that all cables and power connectors of your hard- •

ware components are connected.

To prevent damage to the motherboard, do not allow screws to come in contact with the •

motherboard circuit or its components.

Make sure there are no leftover screws or metal components placed on the motherboard or •

within the computer casing.

Do not place the computer system on an uneven surface •

.

Do not place the computer system in a high-temperature environment. •

Turning on the computer power during the installation process can lead to damage to sys- •

tem components as well as physical harm to the user.

If you are uncertain about any installation steps or have a problem related to the use of the •

product, please consult a certied computer technician.

6) F_PANEL (Front Panel Header)

Connect the power switch, reset switch, speaker, chassis intrusion switch/sensor and system status

indicator on the chassis to this header according to the pin assignments below. Note the positive and

negative pins before connecting the cables.

Power LED

The front panel design may differ by chassis. A front panel module mainly consists of power

switch, reset switch, power LED, hard drive activity LED, speaker and etc. When connecting your

chassis front panel module to this header, make sure the wire assignments and the pin assign-

ments are matched correctly.

MSG/PWR • (Message/Power/Sleep LED, Yellow/Purple):

System Status LED

Connects to the power status indicator on the chassis front panel. The LED

is on when the system is operating. The LED keeps blinking when the sys-

S1 Blinking

tem is in S1 sleep state. The LED is off when the system is in S3/S4 sleep

S3/S4/S5 Off

state or powered off (S5).

PW • (Power Switch, Red):

Connects to the power switch on the chassis front panel. You may congure the way to turn off your

system using the power switch (refer to Chapter 2, "BIOS Setup," "Power Management Setup," for

more information).

SPEAK • (Speaker, Orange):

Connects to the speaker on the chassis front panel. The system reports system startup status by is-

suing a beep code. One single short beep will be heard if no problem is detected at system startup. If

a problem is detected, the BIOS may issue beeps in different patterns to indicate the problem.

HD • (Hard Drive Activity LED, Blue)

Connects to the hard drive activity LED on the chassis front panel. The LED is on when the hard drive

is reading or writing data.

RES • (Reset Switch, Green):

Connects to the reset switch on the chassis front panel. Press the reset switch to restart the computer

if the computer freezes and fails to perform a normal restart.

CI • (Chassis Intrusion Header, Gray):

Connects to the chassis intrusion switch/sensor on the chassis that can detect if the chassis cover

has been removed. This function requires a chassis with a chassis intrusion switch/sensor.

7) F_AUDIO (Front Panel Audio Header)

The front panel audio header supports Intel High Denition audio (HD) and AC'97 audio. You may connect

your chassis front panel audio module to this header. Make sure the wire assignments of the module con-

nector match the pin assignments of the motherboard header. Incorrect connection between the module

connector and the motherboard header will make the device unable to work or even damage it.

The front panel audio header supports HD audio by default. •

Audio signals will be present on both of the front and back panel audio connections simultane- •

ously.

Some chassis provide a front panel audio module that has separated connectors on each wire •

instead of a single plug. For information about connecting the front panel audio module that

has different wire assignments, please contact the chassis manufacturer.

8) F_USB1/F_USB2 (USB 2.0/1.1 Headers)

The headers conform to USB 2.0/1.1 specication. Each USB header can provide two USB ports via an

optional USB bracket. For purchasing the optional USB bracket, please contact the local dealer.

10) CLR_CMOS (Clearing CMOS Jumper)

Use this jumper to clear the CMOS values (e.g. date information and BIOS congurations) and reset

the CMOS values to factory defaults. To clear the CMOS values, place a jumper cap on the two pins to

temporarily short the two pins or use a metal object like a screwdriver to touch the two pins for a few

seconds.

Open: Normal

Short: Clear CMOS Values

Always turn off your computer and unplug the power cord from the power outlet before clear- •

ing the CMOS values.

After clearing the CMOS values and before turning on your computer, be sure to remove the •

jumper cap from the jumper. Failure to do so may cause damage to the motherboard.

After system restart, go to BIOS Setup to load factory defaults (select Load Optimized De- •

faults) or manually congure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS

congurations).

11) BAT (Battery)

The battery provides power to keep the values (such as BIOS congurations, date, and time information)

in the CMOS when the computer is turned off. Replace the battery when the battery voltage drops to a

low level, or the CMOS values may not be accurate or may be lost.

You may clear the CMOS values by removing the battery:

Turn off your computer and unplug the power cord.1.

Gently remove the battery from the battery holder and wait for one minute. 2.

(Or use a metal object like a screwdriver to touch the positive and negative

terminals of the battery holder, making them short for 5 seconds.)

Replace the battery. 3.

Plug in the power cord and restart your computer.4.

Always turn off your computer and unplug the power cord before replacing the battery. •

Replace the battery with an equivalent one. Danger of explosion if the battery is replaced with •

an incorrect model.

Contact the place of purchase or local dealer if you are not able to replace the battery by your- •

self or uncertain about the battery model.

When installing the battery, note the orientation of the positive side (+) and the negative side (-) •

of the battery (the positive side should face up).

Used batteries must be handled in accordance with local environmental regulations. •
