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. 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.
2.3 Installation of Memory Modules (SO-DIMM) AD2550B-ITX motherboard provides two 204-pin DDR3 (Double Data Rate 3) SODIMM 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. Please install the memory module from DDR3_A2 slot for the first priority. Installing a SO-DIMM Please make sure to disconnect power supply before adding or removing SO-DIMMs or the system components. Step 1. Step 2.
2.4 Expansion Slot (PCI Slot) There is 1 PCI slot on this motherboard. PCI slot: The PCI slot is used to install expansion card that has the 32-bit PCI interface. Installing an expansion card Step 1. Step 2. Step 3. Step 4. Step 5. Step 6. 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.
2.5 ASRock Smart Remote Installation Guide ASRock Smart Remote is only used for ASRock motherboard with CIR header. Please refer to below procedures for the quick installation and usage of ASRock Smart Remote. Step1. Find the CIR header located next to the USB 2.0 header on ASRock motherboard. USB 2.0 header (9-pin, black) CIR header (4-pin, gray) Step2. Connect the front USB cable to the USB 2.0 header (as below, pin 1-5) and the CIR header.
3 CIR sensors in different angles 1. 2. 3. Only one of the front USB port can support CIR function. When the CIR function is enabled, the other port will remain USB function. Multi-Angle CIR Receiver is used for front USB only. Please do not use the rear USB bracket to connect it on the rear panel. Multi-Angle CIR Receiver can receive the multi-direction infrared signals (top, down and front), which is compatible with most of the chassis on the market.
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 Clear CMOS Description (CLRCMOS1, 2-pin jumper) (see p.10 No. 11) 2-pin jumper Note: CLRCMOS1 allows you to clear the data in CMOS.
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! (SATAII_2: see p.10, No. 6) SATAII_2 (SATAII_1: see p.10, No. 14) SATAII_1 Serial ATA2 Connectors Serial ATA (SATA) Data Cable These two Serial ATA2 (SATA2) connectors support SATA data cables for internal storage devices.
