Chapter 2: Installation This is a Mini-ITX form factor (6.7" x 6.7", 17.0 x 17.0 cm) motherboard. Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. Make sure to unplug the power cord before installing or removing the motherboard.
2.3 Installation of Memory Modules (SO-DIMM) AD2550RA/U3S3 / AD2550R/U3S3 / AD2550R motherboard provides two 204-pin DDR3 (Double Data Rate 3) SO-DIMM slots. 1. It is not allowed to install a DDR or DDR2 memory module into DDR3 slot; otherwise, this motherboard and SO-DIMM may be damaged.
2.4 Expansion Slots (PCI Express Slots) There is 1 PCI Express slot on this motherboard. PCIE slots: AD2550RA/U3S3 / AD2550R/U3S3 PCIE1 (PCIE 1.0 x1 slot) is used for PCI Express x1 lane width cards. AD2550R PCIE1 (PCIE 1.0 x4 slot) is used for PCI Express x4 lane width cards.
2.5 Onboard Headers and Connectors Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps over these headers and connectors. Plac- ing jumper caps over the headers and connectors will cause permanent damage to the motherboard! Serial ATA2 Connectors These five Serial ATA2 (SATA2) connectors sup- (see p.10,12,14)
Page 26
USB 2.0 Headers Besides two default USB and Ports 2.0 ports on the I/O panel, (9-pin USB0_1) there are are two USB 2.0 (see p.10,12) headers and one port on this motherboard. Each USB 2.0 header can support two (9-pin USB8_9) USB 2.0 ports.

PWRBTN (Power Switch): Connect to the power switch on the chassis front panel. You may configure the way to turn off your system using the power switch. RESET (Reset Switch): Connect 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.
B. Internet status indicator (2-pin LAN1_LED, LAN2_LED) These two 2-pin headers allow you to use the Gigabit internet indicator cable to connect to the LAN status indicator. When this indicator flickers, it means that the internet is properly connected. C. Chassis intrusion pin (4-pin CHASSIS) This header is provided for host computer chassis with chassis intrusion detection designs.
CPU Fan Connectors Please connect the CPU fan (4-pin CPU_FAN1) cable to the connector and (see p.10,12,14) +12V match the black wire to the CPU_FAN_SPEED ground pin. FAN_SPEED_CONTROL Though this motherboard provides a 4-Pin CPU fan (Quiet Fan) connector, 3-Pin CPU fans can still work successfully even with- out the fan speed control function.
