Chapter 2: Installation
This 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.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so may cause physical injuries to you and
damages to motherboard components.
2.1 Screw Holes
Place screws into the holes indicated by circles to secure the motherboard to the
chassis.
Do not over-tighten the screws! Doing so may damage the motherboard.
2.2 Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any component.
2. To avoid damaging the motherboard components due to static electricity,
NEVER place your motherboard directly on the carpet or the like. Also
remember to use a grounded wrist strap or touch a safety grounded object
before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded antistatic pad or
in the bag that comes with the component.
Before you install or remove any component, ensure that the power is
switched off or the power cord is detached from the power supply.
Failure to do so may cause severe damage to the motherboard, peripherals,
and/or components.

13
2.3 Installation of Memory Modules (DIMM)
T48EM1 motherboard provides two 240-pin DDR3 (Double Data Rate 3) DIMM
slots.
It is not allowed to install a DDR or DDR2 memory module into DDR3
slot; otherwise, this motherboard and DIMM may be damaged.
Installing a DIMM
Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align a DIMM on the slot such that the notch on the DIMM matches the
break on the slot.
The DIMM only ts in one correct orientation. It will cause permanent
damage to the motherboard and the DIMM if you force the DIMM into
the slot at incorrect orientation.
Step 3. Firmly insert the DIMM into the slot until the retaining clips at both ends
fully snap back in place and the DIMM is properly seated.

2.4 Expansion Slot (PCI Express Slot)
There is 1 PCI Express slot on this motherboard.
PCIE slot:
PCIE1 (PCIE x16 slot) is used for PCI Express x4 lane width graphics
cards.
Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power
supply is switched off or the power cord is unplugged. Please read the
documentation of the expansion card and make necessary hardware
settings for the card before you start the installation.
Step 2. Remove the system unit cover (if your motherboard is already installed
in a chassis).
Step 3. Remove the bracket facing the slot that you intend to use. Keep the
screws for later use.
Step 4. Align the card connector with the slot and press rmly until the card is
completely seated on the slot.
Step 5. Fasten the card to the chassis with screws.
Step 6. Replace the system cover.

15
2. If you have installed onboard graphics driver from our support CD to your system
already, you can freely enjoy the benets of dual monitor function after your
system boots. If you haven’t installed onboard graphics driver yet, please install
onboard graphics driver from our support CD to your system and restart your
computer.
2.5 Dual Monitor Feature
Dual Monitor Feature
This motherboard supports dual monitor feature. With the internal graphics output
support (DVI-D, D-Sub and HDMI), you can easily enjoy the benets of dual monitor
feature without installing any add-on graphics card to this motherboard. This
motherboard also provides independent display controllers for DVI-D, D-Sub and
HDMI to support dual graphics output so that DVI-D, D-sub and HDMI can drive
same or different display contents.
To enable dual monitor feature, please follow the below steps:
1. Connect DVI-D monitor cable to DVI-D port on the I/O panel, connect D-Sub
monitor cable to D-Sub port on the I/O panel, or connect HDMI monitor cable to
HDMI port on the I/O panel.
HDMI port
D-Sub port
DVI-D port
D-Sub, DVI-D and HDMI monitors cannot be enabled at the same time.
You can only choose the combination: DVI-D + HDMI, DVI-D + D-Sub,
or HDMI + D-Sub.

16
HDCP Function
HDCP function is supported on this motherboard. To use HDCP
function with this motherboard, you need to adopt the monitor
that supports HDCP function as well. Therefore, you can enjoy
the superior display quality with high-denition HDCP
encryption contents. Please refer to below instruction for more
details about HDCP function.
What is HDCP?
HDCP stands for High-Bandwidth Digital Content Protection,
a specication developed by Intel®for protecting digital
entertainment content that uses the DVI interface. HDCP is a
copy protection scheme to eliminate the possibility of
intercepting digital data midstream between the video source,
or transmitter - such as a computer, DVD player or set-top box -
and the digital display, or receiver - such as a monitor, television
or projector. In other words, HDCP specication is designed to
protect the integrity of content as it is being transmitted.
Products compatible with the HDCP scheme such as DVD
players, satellite and cable HDTV set-top-boxes, as well as few
entertainment PCs requires a secure connection to a compliant
display. Due to the increase in manufacturers employing HDCP
in their equipment, it is highly recommended that the HDTV or
LCD monitor you purchase is compatible.

2.6 Jumpers Setup
The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is “Short”. If no jumper cap
is placed on pins, the jumper is “Open”. The
illustration shows a 3-pin jumper whose
pin1 and pin2 are “Short” when jumper cap
is placed on these 2 pins.
Jumper Setting Description
Clear CMOS Jumper
(CLRCMOS1)
(see p.9, No. 6)
Note: CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the
system parameters to default setup, please turn off the computer and unplug
the power cord from the power supply. After waiting for 15 seconds, use a
jumper cap to short pin2 and pin3 on CLRCMOS1 for 5 seconds. However,
please do not clear the CMOS right after 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 ac-
tion. Please be noted that the password, date, time, user default prole, 1394
GUID and MAC address will be cleared only if the CMOS battery is removed.

2.7 Onboard Headers and Connectors
Onboard headers and connectors are NOT jumpers. Do NOT place
jumper caps over these headers and connectors. Placing jumper caps
over the headers and connectors will cause permanent damage of the
motherboard!
Serial ATA3 Connectors These four Serial ATA3 (SATA3)
(SATA3_1: see p.9, No. 12) connectors support SATA data
(SATA3_2: see p.9, No. 10) cables for internal storage
(SATA3_3: see p.9, No. 11) devices. The current SATA3
(SATA3_4: see p.9, No. 9) interface allows up to 6.0 Gb/s
data transfer rate.
Serial ATA (SATA) Either end of the SATA data
Data Cable cable can be connected to the
(Optional) SATA / SATAII / SATA3 hard
disk or the SATAII / SATA3
connector on this motherboard.
USB 2.0 Headers Besides six default USB 2.0
(9-pin USB6_7) ports on the I/O panel, there
(see p.9 No. 19) are two USB 2.0 headers on
this motherboard. Each
USB 2.0 header can support
two USB 2.0 ports.
