WiFi Antennas Installation Guide

B460M-ITX/ac

Step 1

Prepare the WiFi 2.4/5 GHz Antennas that come

with the package.

Step 2

Connect the two WiFi 2.4/5 GHz Antennas to

the antenna connectors. Turn the antenna clock-

wise until it is securely connected.

Step 3

Set the WiFi 2.4/5 GHz Antenna as shown in the

illustration.

*You may need to adjust the direction of

the antenna for a stronger signal.

English

Chapter 2 Installation

is is a Mini-ITX form factor motherboard. Before you install the motherboard,

study the conguration of your chassis to ensure that the motherboard ts into it.

Pre-installation Precautions

Take note of the following precautions before you install motherboard components

or change any motherboard settings.

Make sure to unplug the power cord before installing or removing the motherboard

•

components. Failure to do so may cause physical injuries and damages to motherboard

components.

In order to avoid damage from static electricity to the motherboard’s components,

•

NEVER place your motherboard directly on a carpet. Also remember to use a grounded

wrist strap or touch a safety grounded object before you handle the components.

Hold components by the edges and do not touch the ICs.

•

Whenever you uninstall any components, place them on a grounded anti-static pad or

•

in the bag that comes with the components.

When placing screws to secure the motherboard to the chassis, please do not over-

•

tighten the screws! Doing so may damage the motherboard.

English

2.1 Installing the CPU

1. Before you insert the 120 0-Pin CPU into the socket, please check if the PnP ca p is on the socket, if the CPU sur face is unclean, or if th ere are any b ent pins in the socket. Do not force to insert the CPU into the socket if above situ ation is found. Other wise, the CPU wil l be seriously d amaged.

2. Unplug all power cables be fore installing the CPU.

B460M-ITX/ac

English

Please save and replace the cover if the processor i s removed. e cover must be placed if you wish to return the motherboard for aer service.

2.3 Installing Memory Modules (DIMM)

is motherboard provides two 288-pin DDR4 (Double Data Rate 4) DIMM slots,

and supports Dual Channel Memory Technology.

1. For dual channel conguration, you always need to install identica l (the same

brand, speed , size and chip-type) DDR4 DIMM pairs.

2. It is unable to activate Dual Channel Memor y Technology with only one memory module instal led.

3. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4 slot; otherwise, this motherboard and DIMM may be damaged.

e DIMM only ts in one correct orientation. It will cause permanent dam age to the mothe rboard and the DIMM if you force the DIMM into the slot at incor rect orientation .

B460M-ITX/ac

English

2.4 Expansion Slots (PCI Express Slot)

ere is 1 PCI Express slot slot on the motherboard.

Before installing an ex pansion card, please make sure that the power supply is switched o or the power cord is unplugged. Plea se read the documentation of the expan sion card and mak e necessary hardware settings for the card before you start the installation.

PCIe slot:

PCIE1 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.

B460M-ITX/ac

2.5 Jumpers Setup

e illustration shows how jumpers are setup. When the jumper cap is placed on

the pins, the jumper is “Short”. If no jumper cap is placed on the pins, the jumper is

“Open”.

Clear CMOS Jumper

(CLRMOS1)

(see p.6, No. 16)

CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system

parameters to default setup, please turn o the computer and unplug the power

cord from the power supply. Aer waiting for 15 seconds, use a jumper cap to

short the pins on CLR MOS1 for 5 seconds. However, please do not clear the

CMOS right aer you update the BIOS. If you need to clear the CMOS when you

just nish updating the BIOS, you must boot up the system rst, and then shut it

down before you do the clear-CMOS action. Please be noted that the password,

date, time, and user default prole will be cleared only if the CMOS battery is

removed. Please remember toremove the jumper cap aer clearing the CMOS.

2-pin Jumper

English

If you clear the CMOS, the case open may be detec ted. Please adjust the BIOS option “Clear Status” to clear the record of previou s chassis intrusion status.

2.6 Onboard Headers and Connectors

Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps over these header s and connectors. Placing jumper caps over the headers and connectors will cause permanent damage to the motherboard.

2.7 M.2_SSD (NGFF) Module Installation Guide

The M.2, also known as the Next Generat ion Form Factor (NGFF), is a small size and

versatile card edge connector that aims to replace mPCIe and mSATA. The Ultra M.2

Socket (M2_1) support s M Key type 2280 M.2 SATA3 6.0 Gb/s module and M.2 PCI

Express module up to Gen3 x4 (32 Gb/s).

* Please be noted that if M2_1 is occupied by a SATA-type M.2 device, SATA3_0 will be

disabled.

Installing the M.2_SSD (NGFF) Module

Step 1

Prepare a M.2_SSD (NGFF) module

and the screw.

Step 2

Depending on the PCB type and

length of your M.2_SSD (NGFF)

module, nd the corresponding nut

location to be used.
