Chapter 1 1 General Information
1.1 Introduction AIMB-281 is designed with the Intel H61 for industrial applications that require both performance computing and enhanced power management capabilities. The motherboard supports Intel Core i7-3770 3.4 GHz/Core i5-3550S 3.0 GHz/Core i7-2600 3.4 GHz/Core i5-3570 2.3 GHz/Core i5-3450 3.1 GHz/Core i5-2500T 2.3 GHz/Core i32125 3.3 GHz/Core i3-3220 3.3 GHz/Xeon E3-1275 3.4 GHz/Xeon E3-1225 3.1 GHz/ Pentium G620 2.6 GHz/Celeron G460 1.
1.3.4 Graphics Controller: Intel® HD Graphics Display memory: 256 MB maximum shared memory with 2GB and above system memory installed DVI: Supports DVI up to resolution 1920 x 1200 @ 60Hz refresh rate CRT: Supports VGA up to resolution 2048 x 1536 @ 75Hz refresh rate LVDS: Supports LVDS up to resolution 1920 x 1200 1.3.
1.4 Jumpers and Connectors Connectors on the AIMB-281 motherboard link it to devices such as hard disk drives and a keyboard. In addition, the board has a number of jumpers used to configure your system for your application. The tables below list the function of each of the board jumpers and connectors. Later sections in this chapter give instructions on setting jumpers. Chapter 2 gives instructions for connecting external devices to your motherboard. Table 1.

Warning! Always completely disconnect the power cord from chassis whenever you work with the hardware. Do not make connections while the power is on. Sensitive electronic components can be damaged by sudden power surges. Only experienced electronics personnel should open the PC chassis. Caution! The computer is provided with a battery-powered real-time clock circuit. There is a danger of explosion if battery is incorrectly replaced. Replace only with same or equivalent type recommended by the manufacturer.
1.8.2 Clear CMOS (JCMOS1) This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which includes system setup information such as system passwords. To erase the RTC RAM: 1. Turn OFF the computer and unplug the power cord. 2. Remove the onboard battery. 3. Move the jumper cap from pins 1-2 (default) to pins 2-3.
You do not need to clear the RTC when the system hangs due to overclocking. For system failure due to overclocking, use the C.P.R. (CPU Parameter Recall) feature. Shut down and reboot the system so the BIOS can automatically reset parameter settings to default values. 1.8.3 LVDS Back Light Power Selection Chapter 1 Note! General Information +5V +3.
1.8.4 AT/ATX Power Mode Select (JPSON) This jumper allows you to select ATX Mode or AT mode. ATX MODE (Default) AT MODE 1.9 System Memory AIMB-281 has two 204-pin memory sockets for 1066/1333/1600 MHz memory modules with maximum capacity of 16GB (Maximum 8GB for each DIMM). AIMB-281 supports only non-ECC DDR3 memory modules. 1.10 Memory Installation Procedures To install DIMMs, first make sure the two handles of the DIMM socket are in the “open” position, i.e., the handles lean outward.
1.12 Processor Installation The AIMB-281 is designed for LGA1155, Intel Core i7/Core i5/Core i3/Pentium/Celeron processor.
