Chapter 1: Introduction

1.2 Processor and Chipset Overview

The H12SSW-iN/NT motherboard offers maximum I/O expandability, energy efciency, and

data 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, which

signicantly increases system performance for a multitude of server applications.

The AMD EPYC® 7002 series processor supports the following features:

• ACPI Power Management Logic Support Rev. 6.2

• Adaptive Thermal Management/Monitoring

• PCI-E 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) Specication Version 2.0

1.3 Special Features

This section describes the health monitoring features of the H12SSW-iN/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 H12SSW-iN/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 dene the

sensitivity of the voltage monitor.

17

H12SSW-iN/NT Motherboard User's Manual

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 dene 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-dened 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 airow 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 congure SuperDoctor 5 to provide you

with warnings when the system temperature, CPU temperatures, voltages and fan speeds

go beyond a predened range.

1.5 ACPI Features

ACPI stands for Advanced Conguration and Power Interface. The ACPI specication denes
a exible 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 conguration control. ACPI leverages the Plug and Play BIOS data structures

while providing a processor architecture-independent implementation that is compatible with
Windows 2016 and 2019 operating systems.

18

Chapter 1: Introduction

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 lter 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 Conguration 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.

2.1 Static-Sensitive Devices

Electrostatic Discharge (ESD) can damage electronic com ponents. To prevent damage to your
motherboard, it is important to handle it very carefully. The following measures are generally

sufcient 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 be-

tween the power supply, the case, the mounting fasteners and the motherboard.

• Use only the correct type of CMOS onboard battery as specied by the manufacturer. Do

not install the CMOS battery upside down, which may result in a possible explosion.

Unpacking

The motherboard is shipped in antistatic packaging to avoid static damage. When unpacking
the motherboard, make sure that the person handling it is static protected.

20

Chapter 2: Installation

2.2 Motherboard Installation

All motherboards have standard mounting holes to t different types of chassis. Make sure

that the locations of all the mounting holes for both the motherboard and the chassis match.
Although a chassis may have both plastic and metal mounting fasteners, metal ones are
highly recommended because they ground the motherboard to the chassis. Make sure that
the metal standoffs click in or are screwed in tightly.

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-certied 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

1. 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.

Chapter 2: Installation

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.

7. 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.

8. 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!

27

H12SSW-iN/NT Motherboard User's Manual

9. Gently lower the force frame down onto the rail frame and hold it in place until it is
seated in the Socket housing. Note that the force frame is spring loaded and has to be

held in place before it is secured. Important: Use a torque screwdriver, set it at 16.1

kgf-cm (14.0 lbf-in) with a Torx T20 screw head bit, to prevent damage to the CPU.

10. Place and re-screw the screws in the reverse order to the way you removed them

(holes 1-2-3 in order). When nished, the force frame will be secure over both the rail

frame and CPU package.

28

Chapter 2: Installation

11. After the force frame is secured and the CPU package is in place, now you must install
the heatsink to the frame. Lower the heatsink down till it rests securely over the four
screw holes on CPU package on the socket frame.

12. Using a diagonal pattern, tighten the four screws down on the heatsink in a clockwise

fashion till it is secure. The heatsink will now be secured and you have nished installing

the processor and heatsink onto the motherboard. Repeat this procedure for any
remaining CPU sockets on the motherboard.

2. 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.

3. 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.

4. 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.

5. 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.

6. Grip the handle on the external cap and return it to the rail frame sliding it downwards
till it rests in the frame.

7. Gripping the rail frame, rotate it downwards till it rests above and locks over the socket
housing in its horizontal position.

8. Push and rotate down the force frame till it is over the external cap and rail frame into a
horizontal position.

9. While holding down the force frame, secure it back to the socket frame by securing

DIMM Module Population

When populating the motherboard with DIMM modules, please keep in mind the following:

• Always use DDR4 DIMM modules of the same type, size and speed.

• All eight memory channels per CPU socket should be populated with each channel having

equal capacity. This enables the memory subsystem to operate in eight-way interleaving

mode, which should provide the best performance in most cases.

• In most congurations, populating fewer than eight channels is supported, but not recom-

mended.

System Boot Failure

If the system does not display POST (Power-On-Self-Test) or does not respond after the
power is turned on, check the following:

1. Clear the CMOS settings by unplugging the power cord and contacting both pads on

the CMOS Clear Jumper (JBT1). Refer to chapter 2.8..

2. Remove all components from the motherboard, especially the DIMM modules. Make

sure that system power is on.

3. Turn on the system with only one DIMM module installed. If the system boots, check for

bad DIMM modules or slots by following the Memory Errors Troubleshooting procedure
in this Chapter.

Memory Errors

1. Make sure that the DIMM modules are properly and fully installed.

2. Conrm that you are using the correct memory. Also, it is recommended that you use
the same memory type and speed for all DIMMs in the system. See Section 2.4 for
memory details.

3. Check for bad DIMM modules or slots by swapping modules between slots and noting
the results.

4. Check the power supply voltage 115V/230V switch.

When the System Keeps Losing its Setup Conguration

1. Make sure that you are using a high quality power supply. A poor quality power supply
may cause the system to lose the CMOS setup information. Refer to Section 1 for
details on power supplies.

50

Chapter 3: Troubleshooting

2. 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.

3. If the above steps do not x the setup conguration 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:

1. CPU/BIOS support: Make sure that your CPU is supported and that you have the latest
BIOS installed in your system.

2. 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.

3. HDD support: Make sure that all hard disk drives (HDDs) work properly. Replace the
bad HDDs with good ones.

4. 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.

5. 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.

2. Cable connection: Check to make sure that all cables are connected and working
properly.

3. Using the minimum conguration for troubleshooting: Remove all unnecessary

components (starting with add-on cards rst), and use the minimum conguration (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.

51

H12SSW-iN/NT Motherboard User's Manual

4. 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.

5. 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.

6. To nd 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 rst check with

Appendix C: UEFI BIOS Recovery

Appendix C

UEFI BIOS Recovery

Warning: Do not upgrade the BIOS unless your system has a BIOS-related issue. Flashing

the wrong BIOS can cause irreparable damage to the system. In no event shall Supermicro
be liable for direct, indirect, special, incidental, or consequential damages arising from a BIOS
update. If you need to update the BIOS, do not shut down or reset the system while the BIOS
is updating. Doing so may cause a boot failure.

C.1 Overview

The Unied Extensible Firmware Interface (UEFI) provides a software-based interface
between the operating system and the platform rmware in the pre-boot environment.
The UEFI specication 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 ash 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 ash a new BIOS image if the original main BIOS image
is corrupted. When the system power is on, the boot block codes execute rst. 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

If the BIOS le is corrupted and the system is not able to boot up, this feature will allow you
to recover the BIOS image using a USB-attached device. A USB ash drive or a USB CD/
DVD ROM drive may be used for this purpose. Please note that a USB hard disk drive is
NOT supported. Follow the procedures on the next page to recover the BIOS.

95

H12SSW-iN/NT Motherboard User's Manual

1. Using a different system, copy the standard BIOS binary image le into the root directory
of a USB ash drive with FAT16 or FAT32 format and rename the le to SUPER.ROM.

Note: If you cannot locate the "SUPER.ROM" le in your driver disk, visit our website at
www.supermicro.com to download the correct BIOS image into a USB ash device and
rename it "SUPER.ROM".

2. While the system is turned off, insert the USB device that contains the new BIOS binary

image (SUPER.ROM).

3. Power on the system.

4. After the system is turned on, the system will enter the BIOS Recovery menu. Select

"Proceed with ash update" to start the BIOS recovery process. DO NOT INTERRUPT
THIS PROCESS UNTIL IT FINISHED!

96

Appendix C: UEFI BIOS Recovery

5. After the Boot Sector Recovery Process is complete, press any key to reboot the system.

Notes:

* The BIOS recovery (SUPER.ROM) will not work if BIOS suffered a multi-block crash.

* If you have purchased an OOB license, you can do a BIOS ash again through BMC WebGUI
or SUM. Please refer to these SUPERMICRO software-related videos:

Activate OOB license: https://www.youtube.com/watch?v=V4spX_DOV7I

SUPERMICO BIOS Update: https://www.youtube.com/watch?v=S8z6iOEHGwY

* If the BIOS ash recovery fails, contact our RMA Department to have the BIOS chip

reprogrammed. This will require shipping the board to Supermicro for repair.

Submit your RMA request at https://www.supermicro.com/support/rma

Please make sure to follow all instructions when returning the motherboard.
