Chapter 1: Introduction

1.2 Processor and Chipset Overview

The H11DSi / H11DSi-NT motherboard offers maximum I/O expandability, energy efciency,

and data reliability in a 14nm/7nm process architecture, and is optimized for embedded
storage solutions, networking applications, or cloud-computing platforms.

The H11DSi / H11DSi-NT supports the new microarchitecture 14nm/7nm process technology,
which drastically increases system performance for a multitude of server applications.

The EPYC 7001/7002* Series Processors supports the following features:

• ACPI Power Management Logic Support Rev. 6.1

• Adaptive Thermal Management/Monitoring

• PCIe 3.0 w/ transfer rate of up to 8.0 GT/s and SATA 3.0 w/ transfer rate of up to 6.0 GB/s

• System Management Bus (SMBus) Specication Version 3.1.1

1.3 Special Features

This section describes the health monitoring features of the H11DSi / H11DSi-NT motherboard.
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.

17

H11DSi / H11DSi-NT User's Manual

1.4 System Health Monitoring

This section describes the health monitoring features of the H11DSi / H11DSi-NT motherboard.
The motherboard has an onboard 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
onboard CPU and 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.

18

Chapter 1: Introduction

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 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 Super I/O (Aspeed AST2500 chip) includes a data separator, write pre-compensation
circuitry, decode logic, data rate selection, a clock generator, drive interface control logic and
interrupt and DMA logic. The wide range of functions integrated onto the Super I/O greatly

reduces the number of components required for interfacing with oppy disk drives.

The Super I/O provides one high-speed, 16550 compatible serial communication port
(UART), which supports serial infrared communication. This UART includes a 16-byte 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 a SMI
or SCI function pin. It also features auto power management to reduce power consumption.

The IRQs, DMAs and I/O space resources of the Super I/O can be exibly adjusted to meet

ISA PnP requirements, which support ACPI and APM (Advanced Power Management).

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.

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 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

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

H11DSi / H11DSi-NT 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

DIMM Module Population

There is no specic order or sequence required when installing memory modules. However

do keep the following in mind:

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

• Mixed DIMM speeds can be installed. However, all DIMMs will run at the speed of the

slowest DIMM.

• The motherboard will support odd-numbered modules (1 or 3 modules installed). However,

to achieve the best memory performance, fully populate the motherboard with validated
memory modules.

3.1 Troubleshooting Procedures

Use the following procedures to troubleshoot your system. If you have followed all of the
procedures below and still need assistance, refer to the ‘Technical Support Procedures’ and/
or ‘Returning Merchandise for Service’ section(s) in this chapter. Always disconnect the AC
power cord before adding, changing or installing any non hot-swap hardware components.

Before Power On

1. Check that the LEDM1 is blinking before the motherboard is turned on.

2. Check that the LED3 on the motherboard is on.

3. Make sure that the power connector is connected to your power supply.

4. Make sure that no short circuits exist between the motherboard and chassis.

5. Disconnect all cables from the motherboard, including those for the keyboard and

mouse.

6. Remove all add-on cards.

7. Install a CPU, a heatsink, and at least one DIMM on the motherboard. Check all

jumper settings properly. Make sure that the heatsink is fully seated.

8. Use the correct type of onboard CMOS battery (CR2032) as recommended by the

manufacturer. To avoid possible explosion, do not install the CMOS battery upside down.

No Power

1. Make sure that no short circuits exist between the motherboard and the chassis.

2. Verify that all jumpers are set to their default positions.

3. Turn the power switch on and off to test the system.

4. 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.

49

H11DSi / H11DSi-NT User's Manual

No Video

1. Check that the VGA cable is connected properly, and the monitor is on.

2. Set JPG1 to [1-2] and check if you follow the guidelines to install the memory module (see
DIMM Module Population in chapter 2).

3. Reseat the memory DIMM module

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.

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

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.

What to do if the System is Losing the 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.

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.

50

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 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.

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

H11DSi / H11DSi-NT User's Manual

component in question in another system. If the new system works, the component is
good and the old system has problems.

le 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 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 shut down 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.

4.1 Introduction

This chapter describes the AMIBIOS™ Setup utility for the H11DSi / H11DSi-NT motherboard.

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.

" indicates a submenu. Highlighting such an item and pressing the <Enter> key will open

A "
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.

5.1 Introduction

This chapter describes the AMIBIOS™ Setup utility for the H11DSi / H11DSi-NT motherboard.

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.

" indicates a submenu. Highlighting such an item and pressing <Enter> will open the

A "
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.
