H12SSL Motherboard Series User's Manual

1.2 Processor and Chipset Overview

The H12SSL-i/C/CT/NT motherboards offer maximum I/O expandability, energy efciency,

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 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) Specication 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.

16

Chapter 1: Introduction

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 dene

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 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.

17

H12SSL Motherboard Series User's Manual

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 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 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.

Installation

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.

• 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 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

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.

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
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.

Chapter 3: Troubleshooting

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/SSD support: Make sure that all disk drives work properly. Replace bad HDDs/
SSDs 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.

6. 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:

1. 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.

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.

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

51

H12SSL Motherboard Series User's Manual

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

your distributor or reseller for troubleshooting services. They should know of any possible

problem(s) with the specic system conguration that was sold to you.

1. 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.

2. BIOS upgrades can be downloaded from our website.

Note: Not all BIOS can be ashed depending on the modications to the boot block code.

3. If you still cannot resolve the problem, include the following information when contacting
us for technical support:

• Motherboard model and PCB revision number

• BIOS release date/version (this can be seen on the initial display when your system rst

boots up)

• System conguration

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 les 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

le to your computer. Also, check the current BIOS revision to make sure that it is newer

52

Chapter 3: Troubleshooting

than your BIOS before downloading. You can choose from the zip le and the .exe le. If
you choose the zip BIOS le, please unzip the BIOS le onto a bootable USB device. Run
the batch le using the format FLASH.BAT lename.rom from your bootable USB device to
ash 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 rst 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 ne 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 x update is nished, then you could

enable the IOMMU in BIOS.

Chapter 4

UEFI BIOS

4.1 Introduction

This chapter describes the AMIBIOS™ Setup utility for H12SSL Motherboard Series
motherboards that are equipped with the EPYC 7002 Series Processor. The BIOS is stored

on a chip and can be easily upgraded using a ash program.

Note: Due to periodic changes to the BIOS, some settings may have been added or deleted
and might not yet be recorded in this manual. Please refer to the Manual Download area of

our website for any changes to BIOS that may not be reected in this manual.

Starting the Setup Utility

To enter the BIOS Setup Utility, hit the <Delete> key while the system is booting-up. (In
most cases, the <Delete> key is used to invoke the BIOS setup screen. There are a few
cases when other keys are used, such as <F1>, <F2>, etc.) Each main BIOS menu option
is described in this manual.

The Main BIOS screen has two main frames. The left frame displays all the options that can

be congured. “Grayed-out” options cannot be congured. The right frame displays the key

legend. Above the key legend is an area reserved for a text message. When an option is
selected in the left frame, it is highlighted in white. Often a text message will accompany it.
(Note that BIOS has default text messages built in. We retain the option to include, omit, or
change any of these text messages.) Settings printed in Bold are the default values.

A " " indicates a submenu. Highlighting such an item and pressing the <Enter> key will
open the list of settings within that submenu.

The BIOS setup utility uses a key-based navigation system called hot keys. Most of these
hot keys (<F1>, <F2>, <F3>, <Enter>, <ESC>, <Arrow> keys, etc.) can be used at any time
during the setup navigation process.

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

This feature allows the user to recover a BIOS image using a USB-attached device without

the need for additional utilities. A USB ash device such as a USB ash 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 le 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 le if the media size becomes too large because it contains
too many folders and les.

To perform UEFI BIOS recovery using a USB-attached device, follow the instructions below.

1. Using a different system, copy the "Super.ROM" binary image le into the disc Root "\"
Directory of a USB device or a writeable CD/DVD.

97

H12SSL Motherboard Series User's Manual

Note: If you cannot locate the "Super.ROM" le in your driver disk, visit our website at

www.supermicro.com to download the 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 IS FINISHED!

98

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 has 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.
