Figure 1-3. System Block Diagram
Note: This is a general block diagram and may not exactly represent the features on your motherboard. See the previous pages for the actual specifications of your motherboard.
1.2 Processor and Chipset Overview
The H12SSL-i/C/CT/NT motherboards offer maximum I/O expandability, energy efficiency, and data reliability in a 7-nm process architecture, and is optimized for high performance computing, NVMe storage solutions, and ideal for High Density Data Center applications.
The H12SSL-i/C/CT/NT supports the new microarchitecture 7-nm process technology, which drastically increases system performance for a multitude of server applications.
The AMD EPYC™ 7002/7003 Series Processor supports the following features:
• ACPI Power Management Logic Support Rev. 6.1
• Adaptive Thermal Management/Monitoring
• PCIe 4.0, SATA 3.0 w/transfer rates of up to 6 Gb/s
• System Management Bus (SMBus) Specification Version 2.0
1.3 Special Features
This section describes the health monitoring features of the H12SSL-i/C/CT/NT. The motherboard has an onboard System Hardware Monitor chip that supports system health monitoring.
Recovery from AC Power Loss
The Basic I/O System (BIOS) provides a setting that determines how the system will respond when AC power is lost and then restored to the system. You can choose for the system to remain powered off (in which case you must press the power switch to turn it back on), or for it to automatically return to the power-on state. See the Advanced BIOS Setup section for this setting. The default setting is Last State.
1.4 System Health Monitoring
This section describes the health monitoring features of the H12SSL-i/C/CT/NT motherboard. The motherboard has an onboard Baseboard Management Controller (BMC) chip that supports system health monitoring. Once a voltage becomes unstable, a warning is given or an error message is sent to the screen. The user can adjust the voltage thresholds to define the sensitivity of the voltage monitor.
Onboard Voltage Monitors
The onboard voltage monitor will continuously scan crucial voltage levels. Once a voltage becomes unstable, it will give a warning or send an error message to the screen. Users can adjust the voltage thresholds to define the sensitivity of the voltage monitor. Real time readings of these voltage levels are all displayed in BMC.
Fan Status Monitor with Firmware Control
Users can check the RPM status of the cooling fans through the IPMI Web interface. The chassis fans are controlled by Thermal Management.
Environmental Temperature Control
The thermal control sensor monitors the CPU temperature in real time and will turn on the thermal control fan whenever the CPU temperature exceeds a user-defined threshold. The overheat circuitry runs independently from the CPU. Once the thermal sensor detects that the CPU temperature is too high, it will automatically turn on the thermal fans to prevent the CPU from overheating. The onboard chassis thermal circuitry can monitor the overall system temperature and alert the user when the chassis temperature is too high.
Note: To avoid possible system overheating, please be sure to provide adequate airflow to your system.
System Resource Alert
This feature is available when used with SuperDoctor 5 ^® . SuperDoctor 5 is used to notify the user of certain system events. For example, you can configure SuperDoctor 5 to provide you with warnings when the system temperature, CPU temperatures, voltages and fan speeds go beyond a predefined range.
1.5 ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI specification defines a flexible and abstract hardware interface that provides a standard way to integrate power management features throughout a computer system including its hardware, operating system and application software. This enables the system to automatically turn on and off peripherals such as network cards, hard disk drives and printers.
In addition to enabling operating system-directed power management, ACPI also provides a generic system event mechanism for Plug and Play and an operating system-independent interface for configuration control. ACPI leverages the Plug and Play BIOS data structures while providing a processor architecture-independent implementation that is compatible with Windows 2012/R2 and Windows 2016 operating systems.
1.6 Power Supply
As with all computer products, a stable power source is necessary for proper and reliable operation. It is even more important for processors that have high CPU clock rates. In areas where noisy power transmission is present, you may choose to install a line filter to shield the computer from noise. It is recommended that you also install a power surge protector to help avoid problems caused by power surges.
1.7 Super I/O
The ASpeed AST2500 Super I/O provides one high-speed, 16550 compatible Universal Asynchronous Receiver/Transmitter (UART), which support serial infrared communications. This UART includes a send/receive FIFO, a programmable baud rate generator, complete modem control capability and a processor interrupt system. This UART provides legacy speed with 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 Power Interface), which includes support of legacy and ACPI power management through the System Management Interrupt (SMI) or System Control Interrupt (SCI). It also features auto power management to reduce power consumption.

Installation
2.1 Static-Sensitive Devices
Electrostatic Discharge (ESD) can damage electronic components. To prevent damage to your motherboard, it is important to handle it very carefully. The following measures are generally sufficient 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, memory modules 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 that your chassis provides excellent conductivity between the power supply, the case, the mounting fasteners and the motherboard.

2.3 Processor and Heatsink Installation
Warning: When handling the processor package, avoid placing direct pressure on the label area of the fan.
Important:
- For the Processor/Heatsink installation you need to use a T20 screwdriver when opening/closing the CPU socket.
- Always connect the power cord last, and always remove it before adding, removing or changing any hardware components. Make sure that you install the processor into the CPU socket before you install the CPU heatsink.
- If you buy a CPU separately, make sure that you use an AMD-certified multi-directional heatsink only.
- Make sure to install the motherboard into the chassis before you install the CPU heatsink.
- When receiving a motherboard without a processor pre-installed, make sure that the plastic CPU socket cap is in place and none of the socket pins are bent; otherwise, contact your retailer immediately.
• Refer to the Supermicro website for updates on CPU support.
Installing the Processor and Heatsink
- Unscrew the screws holding down Force Frame in the sequence of 3-2-1. The screws are numbered on the Force Frame next to each screw hole.

- The spring-loaded Force Frame will raise up after the last screw securing it (#1) is removed. Gently allow it to lift up to its stopping position.

While keeping a secure grip of the Rail Frame, lift it to a position so you can do the next step of removing the External Cap.
Note: The Rail Frame is spring loaded, so keep a secure grip on it as you lift it so it does not snap up.

- Remove the External Cap from the Rail Frame by pulling it upwards through the rail guides on the Rail Frame.

-
The CPU Package is shipped from the factory with the Carrier Frame pre-assembled. Grip the handle of the Carrier Frame/CPU Package assembly from its shipping tray, and while gripping the handle, align the flanges of the Carrier Frame onto the rails of the Rail Frame so its pins will be at the bottom when the Rail Frame is lowered later.
-
Slide the Carrier Frame/CPU Package downwards to the bottom of the Rail Frame. Ensure the flanges are secure on the rails as you lower it downwards.

Note: You can only install the CPU inside the socket in one direction with the handle at the top. Make sure that it is properly inserted into the CPU socket before closing the Rail Frame plate. If it doesn't close properly, do not force it as it may damage your CPU. Instead, open the Rail Frame plate again, and double-check that the CPU is aligned properly.
- Lift up the Rail Frame till it securely rests in upright position. Then remove the PnP Cover Cap from the CPU socket below. Grip the two lift tabs marked "Remove" at the middle of the cap and pull vertically upwards to remove the PnP Cover Cap.

Warning! The exposed socket contacts are extremely vulnerable and can be damaged easily. Do not touch or drop objects onto the contacts and be careful removing the PnP Cover Cap and when placing the Rail Frame over the socket.
- Gently lower the Rail Frame down onto the socket until the latches on the Rail Frame engage with the Socket housing. and it rests in place. DO NOT force it into place!

Un-installing the Processor and Heatsink
- Remove the heatsink attached to the top of the CPU Package by reversing the installation procedure.
- Clean the Thermal grease left by the heatsink on the CPU package lid to limit the risk of it contaminating the CPU package land pads or contacts in the socket housing.
- Reverse the procedure for installing the Force Frame onto the socket, unscrewing the plate in the 3-2-1 screw order and lift the Force Frame to the vertical position.
- Lift the Rail Frame using the lift tabs near the front end of the Rail Frame. Note that the Rail Frame is spring loaded, so be careful lifting it up into a vertical position.
- Grip the handle of the Carrier Frame and pull upwards to extract it from the Rail Frame. Return the Carrier Frame/CPU Package to its original shipping container.
- Grip the handle on the External Cap and return it to the Rail Frame sliding it downwards till it rests in the frame.
- Gripping the Rail Frame, rotate it downwards till it rests above and locks over the socket housing in its horizontal position.
- Push and rotate down the Force Frame till it is over the External Cap and Rail Frame into a horizontal position.
- While holding down the Force Frame, secure it back to the socket frame by securing screw 1 in place. Note that without a CPU Package in place, it is not necessary to tighten down screws 2 and 3 at this time.

2.8 Jumper Settings
How Jumpers Work
To modify the operation of the motherboard, jumpers can be used to choose between optional settings. Jumpers create shorts between two pins to change the function of the connector. Pin #1 is identified with a thicker border line on the printed circuit board. See the diagram below for an example of jumping pins 1 and 2. Refer to the motherboard layout page for jumper locations.
Note: On two-pin jumpers, "Closed" means the jumper is on and "Open" means the jumper is off the pins.

Clear CMOS (JBT1)
JBT1 is used to clear CMOS, which will also clear any passwords. Instead of pins, this jumper consists of contact pads to prevent accidentally clearing the contents of CMOS.
To Clear CMOS
- First power down the system and unplug the power cord(s).
- Remove the cover of the chassis to access the motherboard.
- Remove the onboard battery from the motherboard.
- Short the CMOS pads with a metal object such as a small screwdriver for at least four seconds.
- Remove the screwdriver (or shorting device).
- Replace the cover, reconnect the power cord(s), and power on the system.
Note: Clearing CMOS will also clear all passwords.
Do not use the PW_ON connector to clear CMOS.

- Make sure that you are using a qualified power supply. An unqualified power supply may cause the system to lose the CMOS setup information. Refer to Section 1.6 for details on recommended power supplies.
- The battery on your motherboard may be old. Check to verify that it still supplies \~3VDC. If it does not, replace it with a new one.
- If the above steps do not fix the setup configuration problem, contact your vendor for repairs.
When the System Becomes Unstable
A. If the system becomes unstable during or after OS installation, check the following:
- CPU/BIOS support: Make sure that your CPU is supported and that you have the latest BIOS installed in your system.
- Memory support: Make sure that the memory modules are supported by testing the modules using memtest86 or a similar utility.
Note: Refer to the product page on our website at http://www.supermicro.com for memory and CPU support and updates.
- HDD/SSD support: Make sure that all disk drives work properly. Replace bad HDDs/SSDs with good ones.
- System cooling: Check the system cooling to make sure that all heatsink fans and CPU/system fans, etc., work properly. Check the hardware monitoring settings in the IPMI to make sure that the CPU and system temperatures are within the normal range. Also check the front panel Overheat LED and make sure that it is not on.
- Adequate power supply: Make sure that the power supply provides adequate power to the system. Make sure that all power connectors are connected. Please refer to our website for more information on the minimum power requirements.
- Proper software support: Make sure that the correct drivers are used.
B. If the system becomes unstable before or during OS installation, check the following:
- Source of installation: Make sure that the devices used for installation are working properly, including boot devices such as CD/DVD and CD/DVD-ROM.
- Cable connection: Check to make sure that all cables are connected and working properly.
- Using the minimum configuration for troubleshooting: Remove all unnecessary components (starting with add-on cards first), and use the minimum configuration (but with a CPU and a memory module installed) to identify the trouble areas. Refer to the steps listed in Section A above for proper troubleshooting procedures.
- Identifying bad components by isolating them: If necessary, remove a component in question from the chassis, and test it in isolation to make sure that it works properly. Replace a bad component with a good one.
- Check and change one component at a time instead of changing several items at the same time. This will help isolate and identify the problem.
- To find out if a component is good, swap this component with a new one to see if the system will work properly. If so, then the old component is bad. You can also install the
component in question in another system. If the new system works, the component is good and the old system has problems.
3.2 Technical Support Procedures
Before contacting Technical Support, please take the following steps. Also, note that as a motherboard manufacturer, we do not sell directly to end-users, so it is best to first check with your distributor or reseller for troubleshooting services. They should know of any possible problem(s) with the specific system configuration that was sold to you.
- Please review the 'Troubleshooting Procedures' and 'Frequently Asked Questions' (FAQs) sections in this chapter or see the FAQs on our website before contacting Technical Support.
- BIOS upgrades can be downloaded from our website.
Note: Not all BIOS can be flashed depending on the modifications to the boot block code.
-
If you still cannot resolve the problem, include the following information when contacting us for technical support:
-
Motherboard model and PCB revision number
- System configuration
- BIOS release date/version (this can be seen on the initial display when your system first boots up)
An example of a Technical Support form is posted on our website.
Distributors: For immediate assistance, please have your account number ready when contacting our technical support department by e-mail.
3.3 Frequently Asked Questions
Question: What type of memory does my motherboard support?
Answer: The H12SSL-i/C/CT/NT supports up to 2TB Registered ECC DDR4-3200 SDRAM in eight DIMM slots. See Section 2.4 for details on installing memory.
Question: How do I update my BIOS?
Answer: It is recommended that you do not upgrade your BIOS if you are not experiencing any problems with your system. Updated BIOS files are located on our website at http://www.supermicro.com. Please check our BIOS warning message and the information on how to update your BIOS on our website. Select your motherboard model and download the BIOS file to your computer. Also, check the current BIOS revision to make sure that it is newer
than your BIOS before downloading. You can choose from the zip file and the .exe file. If you choose the zip BIOS file, please unzip the BIOS file onto a bootable USB device. Run the batch file using the format FLASH.BAT filename.rom from your bootable USB device to flash the BIOS. Then, your system will automatically reboot.
Question: Why can't I turn off the power using the momentary power on/off switch?
Answer: The instant power off function is controlled in BIOS by the Power Button Mode setting. When the On/Off feature is enabled, the motherboard will have instant off capabilities as long as the BIOS has control of the system. When the Standby or Suspend feature is enabled or when the BIOS is not in control such as during memory count (the first screen that appears when the system is turned on), the momentary on/off switch must be held for more than four seconds to shutdown the system. This feature is required to implement the ACPI features on the motherboard.
Question: For the AMD EPYC platform, we found that the Windows Server 2012/2016 OS would not install properly. It however works fine with Linux OS, any suggestions?
Answer: This issue is due to Windows server OS' compatibility with the virtualization function, we suggest to disable IOMMU (Input/Output Memory Management Unit) before installing the Windows Server OS. After installing the OS and hot fix update is finished, then you could enable the IOMMU in BIOS.

C.1 Overview
The Unified Extensible Firmware Interface (UEFI) provides a software-based interface between the operating system and the platform firmware in the pre-boot environment. The UEFI specification supports an architecture-independent mechanism for add-on card initialization to allow the UEFI OS loader, which is stored in the add-on card, to boot the system. The UEFI offers clean, hands-off control to a computer system at bootup.
C.2 Recovering the UEFI BIOS Image
A UEFI BIOS flash chip consists of a recovery BIOS block and a main BIOS block (a main BIOS image). The boot block contains critical BIOS codes, including memory detection and recovery codes for the user to flash a new BIOS image if the original main BIOS image is corrupted. When the system power is on, the boot block codes execute first. Once it is completed, the main BIOS code will continue with system initialization and bootup.
C.3 Recovering the BIOS Block with a USB Device
This feature allows the user to recover a BIOS image using a USB-attached device without the need for additional utilities. A USB flash device such as a USB flash drive or a USB CD/DVD device can be used for this purpose. A USB hard disk drive cannot be used for BIOS recovery at this time.
The file system supported by UEFI is FAT (including FAT12, FAT16, and FAT32) installed on a bootable or non-bootable USB-attached device. Note that the BIOS might need several minutes to locate the SUPER.ROM file if the media size becomes too large because it contains too many folders and files.
To perform UEFI BIOS recovery using a USB-attached device, follow the instructions below.
- Using a different system, copy the "Super.ROM" binary image file into the disc Root "\" Directory of a USB device or a writeable CD/DVD.
Note: If you cannot locate the "Super.ROM" file in your driver disk, visit our website at www.supermicro.com to download the BIOS image into a USB flash device and rename it "Super.ROM".
-
While the system is turned off, insert the USB device that contains the new BIOS binary image (SUPER.ROM).
-
Power on the system.

- After the system is turned on, the system will enter the BIOS Recovery menu. Select "Proceed with flash update" to start the BIOS recovery process. DO NOT INTERRUPT THIS PROCESS UNTIL IT IS FINISHED!

Notes:
• The BIOS recovery (SUPER.ROM) will not work if BIOS has a multi-block crash.
- If you have purchased an OOB license, you can do a BIOS flash again through BMC WebGUI or SUM. Please refer to these SUPERMICRO software-related videos:
