Super X11SDD-8C/18C-F User's Manual

1.2 Processor Overview

The Intel Xeon D-2141I and D-2191 series processor offers performance, reliability, and
high intelligence. As a low-power system-on-a-chip motherboard, the X11SDD-8C/18C-F is

optimized for a variety of workloads that include networking and cloud storage.

• 14nm silicon process technology enables high density, lower-power system designs with

thermal design points of 60W to 110W. (D-2141I 65W, D-2191 86W)

• Up to four integrated ports of 10 Gigabit Intel® Ethernet

• Up to 512 GB of memory

• Intel Turbo Boost Technology 2.0, Intel Speed Shift Technology, and Intel Hyper-Threading

Technology (Intel HT Technology).

• Intel Advanced Encryption Standard New Instructions (Intel AES-NI) provide integrated

support for fast, low-overhead encryption, and Intel Trusted Execution Technology (Intel

TXT) provides platform verication (through authenticated boot) to enable strong security

with reduced performance impact

• New Intel Advanced Vector Extensions 512 (Intel AVX-512)

• Includes Intel Node Manager (Intel NM) Base for adaptive power management

1.3 Special Features

This section describes the health monitoring features of the X11SDD-8C/18C-F 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.

16

Chapter 1: Introduction

1.4 System Health Monitoring

This section describes the health monitoring features of the X11SDD-8C/18C-F 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.

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 BIOS.

Fan Status Monitor with Firmware Control

The system health monitor embedded in the BMC chip can check the RPM status of the
cooling fans. The CPU and chassis fans are controlled via lPMI.

Environmental Temperature Control

System Health sensors monitor temperatures and voltage settings of onboard processors
and the system in real time via the IPMI interface. Whenever the temperature of the CPU or

the system exceeds a user-dened threshold, system/CPU cooling fans will be turned on to

prevent the CPU or the system from overheating

Note: To avoid possible system overheating, please provide adequate airow to your

system.

System Resource Alert

This feature is available when used with SuperDoctor 5® in the Windows OS or in the Linux
environment. SuperDoctor is used to notify the user of certain system events. For example,

you can congure SuperDoctor to provide you with warnings when the system temperature,
CPU temperatures, voltages and fan speeds go beyond a predened range.

17

Super X11SDD-8C/18C-F 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 CD-ROMs, 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.

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) provides a high-speed, 16550 compatible serial
communication port (UART), which supports serial infrared communiciation. The UART
inlcudes send/receive FIFO, a programmable baud rate generator, complete modem control
capability, and a processor interrupt system. The UART provides legacy speed with a 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, supporting hihger 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.

Chapter 2

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 your computer chassis provides excellent conductivity

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

• Use only the correct type of onboard CMOS battery. Do not install the onboard battery

upside down to avoid 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.

19

Super X11SDD-8C/18C-F User's Manual

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 Memory Support and Installation

Note: Check the Supermicro website for recommended memory modules.

Important: Exercise extreme care when installing or removing DIMM modules to pre-

vent any possible damage.

Memory Support

The X11SDD-8C/18C-F motherboard supports up to 256GB Registered ECC RDIMM and up
to 512GB LRDIMM. Populating these DIMM slots with memory modules of the same type and
size will result in interleaved memory, which will improve memory performance.

DIMM Module Population Conguration

For optimal memory performance, follow the table below when populating memory.

Chapter 2: Installation

DIMM Module Population Sequence

When installing memory modules, the DIMM slots should be populated in the following order:
DIMMA1, DIMMB1, DIMMD1, DIMME1.

• 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 (one or three modules installed).

However, for best memory performance, install DIMM modules in pairs to activate memory
interleaving.

2.6 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 identied with a square solder pad 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 the pins and Open means
the jumper is off.

CMOS Clear

JBT1 is used to clear the CMOS. Instead of pins, this jumper consists of contact pads to
prevent accidental clearing of the CMOS. To clear the CMOS, use a metal object such as a
small screwdriver to touch both pads at the same time to short the connection.

Note: Shut down the system and then short JBT1 to clear the CMOS.

Chapter 3: Troubleshooting

3. Remove all memory modules and turn on the system (if the alarm is on, check the
specs of memory modules, reset the memory or try a different one).

System Boot Failure

If the system does not display POST or does not respond after the power is turned on, check
the following:

1. Check for any error beep from the motherboard speaker.

• If there is no error beep, try to turn on the system without DIMM modules installed. If there

is still no error beep, replace the motherboard.

• If there are error beeps, clear the CMOS settings by unplugging the power cord and con-

tacting both pads on the CMOS clear jumper (JBT1). (Refer to Section 2-6 in Chapter 2.)

2. Remove all components from the motherboard, especially the DIMM modules. Make
sure that system power is on and that memory error beeps are activated.

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

When a no-memory beep code is issued by the system, check the following:

1. Make sure that the memory modules are compatible with the system and that the
DIMMs are properly and fully installed. Click on the Tested Memory List link on the
motherboard product page to see a list of supported memory.

2. Check if different speeds of DIMMs have been installed. It is strongly recommended that
you use the same RAM type and speed for all DIMMs in the system.

3. Make sure that you are using the correct type of DIMM modules recommended by the
manufacturer.

4. Check for bad DIMM modules or slots by swapping a single module among all memory
slots and check the results.

5. Make sure that all memory modules are fully seated in their slots. Follow the instructions
given in Section 2-4 in Chapter 2.

6. Please follow the instructions given in the DIMM population tables listed in Section 2-4
to install your memory modules.

Losing the System's 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 2-6 for
details on recommended 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.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: Click on the Tested Memory List link on the motherboard product page to see
a list of supported memory.

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

properly.

42

Chapter 3: Troubleshooting

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

UEFI BIOS

4.1 Introduction

This chapter describes the AMIBIOS™ Setup utility for the X11SDD 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 the 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>, <Enter>, <ESC>, <Arrow> keys, etc.) can be used at any time during the
setup navigation process.

48

During the POST (Power-On Self-Test) routines, which are performed upon each system
boot, errors may occur.

Non-fatal errors are those which, in most cases, allow the system to continue to boot. These
error messages normally appear on the screen.

Fatal errors will not allow the system to continue with bootup. If a fatal error occurs, you
should consult with your system manufacturer for possible repairs.

These fatal errors are usually communicated through a series of audible beeps. The table
below lists some common errors and their corresponding beep codes encountered by users.

Appendix D

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 to avoid possible boot failure.

D.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 that will allow the UEFI
OS loader stored in an add-on card to boot the system. The UEFI offers clean, hands-off

management to a computer during system boot.

D.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 recovery block contains critical BIOS codes, including memory detection
and recovery codes for the user to ash a healthy BIOS image if the original main BIOS image
is corrupted. When the system power is turned on, the recovery block codes execute rst.

Once this process is complete, the main BIOS code will continue with system initialization

and the remaining POST (Power-On Self-Test) routines.

Note 1: Follow the BIOS recovery instructions below for BIOS recovery when the main

BIOS block crashes.

Note 2: When the BIOS recovery block crashes, you will need to follow the procedures
to make a Returned Merchandise Authorization (RMA) request. (For a RMA request,
please see section 3.5 for more information). Also, you may use the Supermicro Up­date Manager (SUM) Out-of-Band (OOB) (https://www.supermicro.com.tw/products/

nfo/SMS_SUM.cfm) to reash the BIOS.
