Chapter 1: Introduction1.2 Processor and Chipset OverviewThe H12SSW-iN/NT motherboard offers maximum I/O expandability, energy efficiency, anddata reliability in a 7-nm process architecture. It is optimized for high-performance computing,NVMe storage solutions, and ideal for High Density Data Center applications.The H12SSW-iN/NT supports the new 7 nm microarchitecture process technology, whichsignificantly increases system performance for a multitude of server applications.The AMD EPYC 7002/7003 series supports the following features: ACPI Power Management Logic Support Rev. 6.2 Adaptive Thermal Management/Monitoring PCIe 4.0 w/transfer rates of up to 16 Gb/s SATA 3.0 w/transfer rates of up to 6 Gb/s System Management Bus (SMBus) Specification Version 2.01.3 Special FeaturesThis section describes the health monitoring features of the H12SSW-iN/NT. The motherboardhas an onboard System Hardware Monitor chip that supports system health monitoring.Recovery from AC Power LossThe Basic I/O System (BIOS) provides a setting that determines how the system will respondwhen AC power is lost and then restored to the system. You can choose for the system toremain powered off (in which case you must press the power switch to turn it back on), orfor it to automatically return to the power-on state. See the Advanced BIOS Setup sectionfor this setting. The default setting is Last State.1.4 System Health MonitoringThis section describes the health monitoring features of the H12SSW-iN/NT motherboard. Themotherboard has an onboard Baseboard Management Controller (BMC) chip that supportssystem health monitoring. Once a voltage becomes unstable, a warning is given or an errormessage is sent to the screen. The user can adjust the voltage thresholds to define thesensitivity of the voltage monitor.17
H12SSW-iN/NT Motherboard User's ManualOnboard Voltage MonitorsThe onboard voltage monitor will continuously scan crucial voltage levels. Once a voltagebecomes unstable, it will give a warning or send an error message to the screen. Users canadjust the voltage thresholds to define the sensitivity of the voltage monitor. Real time readingsof these voltage levels are all displayed in BMC.Fan Status Monitor with Firmware ControlUsers can check the RPM status of the cooling fans through the IPMI Web interface. Thechassis fans are controlled by Thermal Management.Environmental Temperature ControlThe thermal control sensor monitors the CPU temperature in real time and will turn on thethermal control fan whenever the CPU temperature exceeds a user-defined threshold. Theoverheat circuitry runs independently from the CPU. Once the thermal sensor detects thatthe CPU temperature is too high, it will automatically turn on the thermal fans to prevent theCPU from overheating. The onboard chassis thermal circuitry can monitor the overall systemtemperature and alert the user when the chassis temperature is too high.Note: To avoid possible system overheating, please be sure to provide adequate airflow toyour system.System Resource AlertThis feature is available when used with SuperDoctor 5 . SuperDoctor 5 is used to notify theuser of certain system events. For example, you can configure SuperDoctor 5 to provide youwith warnings when the system temperature, CPU temperatures, voltages and fan speedsgo beyond a predefined range.1.5 ACPI FeaturesACPI stands for Advanced Configuration and Power Interface. The ACPI specification definesa flexible and abstract hardware interface that provides a standard way to integrate powermanagement features throughout a computer system including its hardware, operating systemand application software. This enables the system to automatically turn on and off peripheralssuch as network cards, hard disk drives and printers.In addition to enabling operating system-directed power management, ACPI also provides ageneric system event mechanism for Plug and Play and an operating system-independentinterface for configuration control. ACPI leverages the Plug and Play BIOS data structureswhile providing a processor architecture-independent implementation that is compatible withWindows 2016 and 2019 operating systems.18
Chapter 1: Introduction1.6 Power SupplyAs with all computer products, a stable power source is necessary for proper and reliableoperation. It is even more important for processors that have high CPU clock rates. In areaswhere noisy power transmission is present, you may choose to install a line filter to shieldthe computer from noise. It is recommended that you also install a power surge protector tohelp avoid problems caused by power surges.1.7 Super I/OThe ASpeed AST2500 Super I/O provides one high-speed, 16550 compatible UniversalAsynchronous Receiver/Transmitter (UART), which support serial infrared communications.This UART includes a send/receive FIFO, a programmable baud rate generator, completemodem control capability and a processor interrupt system. This UART provides legacy speedwith baud rate of up to 115.2 Kbps as well as an advanced speed with baud rates of 250 K,500 K, or 1 Mb/s, which support higher speed modems.The Super I/O provides functions that comply with ACPI (Advanced Configuration and PowerInterface), which includes support of legacy and ACPI power management through the SystemManagement Interrupt (SMI) or System Control Interrupt (SCI). It also features auto powermanagement to reduce power consumption.19
H12SSW-iN/NT Motherboard User's ManualChapter 2Installation2.1 Static-Sensitive DevicesElectrostatic Discharge (ESD) can damage electronic com ponents. To prevent damage to yourmotherboard, it is important to handle it very carefully. The following measures are generallysufficient to protect your equipment from ESD.Precautions Use a grounded wrist strap designed to prevent static discharge. Touch a grounded metal object before removing the board from the antistatic bag. Handle the board by its edges only; do not touch its components, peripheral chips, memorymodules or gold contacts. When handling chips or modules, avoid touching their pins. Put the motherboard and peripherals back into their antistatic bags when not in use. For grounding purposes, make sure th
