Caution 3.1 Unplug the power cord from the wall socket before touching any component. Use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity. Hold components by the edges to avoid touching the ICs on them. Whenever you uninstall any component, place it on a grounded anti-static pad or in the bag that came with the component. Before you install or remove any component, ensure that the ATX power supply 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. Motherboard Overview Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. Refer to the chassis documentation before installing the motherboard. Warning Make sure to unplug the power cord before installing or removing the motherboard. Failure to do so can cause you physical injury and damage motherboard components. 3.1.1 Placement Direction When installing the motherboard, make sure that you place it into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis as indicated in the image below. 3.1.2 Screw Holes Place four (4) screws into the holes indicated by circles to secure the motherboard to the chassis. Do not over-tighten the screws! Doing so can damage the motherboard. Caution Hardware Installation 19 MANO861 Mini ITX Board Place this side towards the rear of the chassis. 3.2 Central Processing Unit (CPU) ® The motherboard comes with a surface mount Intel LGA1155 socket supports 22nm/32nm ® ® ® Intel Core™ i7 / i5 / i3 / Pentium / Celeron processor in the LGA1155 package. Important Caution 20 ® Your boxed Intel Core™ i7/ i5/ i3 mobile processor package should come with installation instructions for the CPU, fan and heatsink assembly. If the instructions in this section do not match the CPU documentation, follow the latter. Upon purchase of the motherboard, make sure that the PnP cap is on the socket and the socket pins are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the PnP cap/socket pins/motherboard components. Axiomtek will shoulder the cost of repair only if the damage is shipment/transit-related. Keep the cap after installing the motherboard. Axiomtek will process Return Merchandise Authorization (RMA) requests only if the motherboard comes with the cap on the LGA1155 socket. The product warranty does not cover damage to the socket pins resulting from incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP cap. Install the CPU fan and heatsink assembly before you install motherboard to the chassis. If you purchased a separate CPU heatsink and fan assembly, make sure that you have properly applied Thermal Interface Material to the CPU heatsink or CPU before you install the heatsink and fan assembly. Hardware Installation MANO861 Mini ITX Board 3.2.1 1. Installing the CPU Locate the CPU socket on the motherboard. Before installing the CPU, make sure that the socket box is facing towards you and the load lever is on your left. Caution 2. Separate CPU cooler and its base first with screw driver. 3. Assemble the CPU fan retention module. Hardware Installation 21 MANO861 Mini ITX Board 4. Position the CPU over the socket, making sure that the gold triangle is the same side as CPU socket triangle. CPU socket triangle 5. Lock and unlock CPU. Caution 22 Gold triangle The CPU fits in only one correct orientation. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU! Hardware Installation MANO861 Mini ITX Board 3.2.2 Installing the CPU Heatsink and Fan 1. 2. Place the heatsink base on the relative bottom of motherboard. Place the heatsink assembly on the top of the CPU, making sure that the four fasteners match the holes on the motherboard. 3. Screw tightly the four fasteners. 4. Connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN. Do not forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug this connector. Important Hardware Installation 23 MANO861 Mini ITX Board 3.3 System Memory 3.3.1 Overview The motherboard comes with two 204-pin Double Data Rate 3 (DDR3) Small Outline Dual Inline Memory Modules (SO-DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR SO-DIMM but has a 204-pin footprint compared to the 204-pin DDR2 DIMM. DDR3 DIMMs are notched differently to prevent installation on a DDR2 DIMM socket. The following figure illustrates the location of the sockets: Channel Slot Channel A Channel B DIMMA1 DIMMB1 204-pin DDR3 SO-DIMM sockets 24 Hardware Installation MANO861 Mini ITX Board 3.3.2 Memory Configurations You may install 1GB, 2GB, and 4GB non-ECC DDR3 SO-DIMMs into the SO-DIMM sockets using the memory configurations in this section. Important 3.3.3 IF you installed four 1GB memory modules, the system may detect less than 3GB of total memory because of address space allocation for other critical functions. This limitation applies to Windows XP 32-bit version operating system since it does not support PAE (Physical Address Extension) mode. IF you install Windows XP 32-bit version operating system, we recommend that you install less than 3GB of total memory. For dual channel configuration, the total size of memory module(s) installed per channel must be the same for better performance (DIMMA1=DIMMB1). Always install SO-DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor. Due to CPU limitation, SO-DIMM modules with 128Mb memory chips or double-sided x16 memory chips are not supported in this motherboard. Installing a SO-DIMM 1. Unlock a SO-DIMM socket by pressing the retaining clips outward. 2. Align a SO-DIMM on the socket such that the notch on the SO-DIMM matches the break on the socket.

Some embedded systems are not watched by human for 24 hours. It is usually too slow to wait for someone to reboot when computer hangs. The systems need to be able to reset automatically when things go wrong. The watchdog timer gives us solution. The watchdog timer is a counter that triggers a system reset when it counts down to zero from a preset value. The software starts counter with an initial value and must reset it periodically. If the counter ever reaches zero which means the software has crashed, the system will reboot. The integrated watchdog timer can be set up by programming. There are 1~255 levels available. How to Use Watchdog Timer Assume that program A needs to keep running in a system. The value of watchdog timer must be set bigger than the running time of program A. Then, after the running time of program A is finished, either to disable or to reset watchdog timer. When program A has problems that cause system shut down, the system can be rebooted by watchdog timer when the value of watchdog timer has counted down to 0.
