Super X11SCL-IF User's Manual

1.2 Processor and Chipset Overview

Built upon the functionality and capability of the Intel Xeon E-2100, 8th Generation Core
i3, Pentium, and Celeron series processor (Socket H4 - LGA 1151) and the Intel C242

chipset, the X11SCL-IF motherboard provides optimized system performance, efcient power

management, and features based on cutting edge technology to address the needs of next-

generation computer users. The X11SCL-IF offers maximum I/O exibility and data reliability

in a 14-nm process architecture and is ideal for entry-level computing, SMB and micro server
platforms.

The Intel Xeon E-2100, 8th Generation Core i3, Pentium, and Celeron processor and the
C242 chipset support the following features:

• DDR4 288-pin memory support

• Support of SMBus speeds of up to 400KHz for BMC connectivity

• Improved I/O capabilities to high-storage-capacity congurations

• SPI Enhancements

• BMC supports remote management, virtualization, and the security package for enterprise

platforms

1.3 Special Features

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

Onboard Voltage Monitors

An onboard voltage monitor will continuously scan the voltages of the onboard chipset,
memory, CPU, and battery. 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. Real time voltage levels are displayed in IPMI.

18

Chapter 1: Introduction

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 in the BMC monitor the 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 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, 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 Server 2016.

19

Super X11SCL-IF User's Manual

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 where
noisy power transmission is present.

The X11SCL-IF motherboard accommodates a 24-pin ATX power supply. Although most

power supplies generally meet the specications required by the CPU, some are inadequate.

In addition, one 12V 4-pin power connection is also required to ensure adequate power to
the system.

Warning: To avoid damaging the power supply or the motherboard, be sure to use
power supplies that contain 24-pins and 4-pins, respectively. Connect the power sup­plies to the 24-pin power connector (JPW1), and the 4-pin power connector (JPW2)
on the motherboard. Failure in doing so may void the manufacturer warranty on your
power supply and motherboard.

It is strongly recommended that you use a high quality power supply that meets ATX power

supply Specication 2.02 or above and is SSI compliant. (For more information, please refer

to the website at http://www.ssiforum.org/).

1.7 Serial Port

The X11SCL-IF motherboard supports one serial communication connection. COM Port 1
can be used for input/output. The UART provides legacy speeds with a baud rate of up to

2.1 Static-Sensitive Devices

Electrostatic Discharge (ESD) can damage electronic com ponents. To avoid damaging your
system board, 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 motherboard 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 computer chassis provides excellent conduc-

tivity 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.

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.

Location of Mounting Holes

Note: 1) To avoid damaging the motherboard and its components, please do not use

a force greater than 8 lbf-in on each mounting screw during motherboard installation.

2) Some components are very close to the mounting holes. Please take precaution­ary measures to avoid damaging these components when installing the motherboard
to the chassis.

22

Chapter 2: Installation

Installing the Motherboard

1. Install the I/O shield into the back of the chassis, if applicable.

2. Locate the mounting holes on the motherboard. See the previous page for the location.

3. Locate the matching mounting holes on the chassis. Align the mounting holes on the
motherboard against the mounting holes on the chassis.

4. Install standoffs in the chassis as needed.

5. Install the motherboard into the chassis carefully to avoid damaging other motherboard
components.

6. Using the Phillips screwdriver, insert a pan head #6 screw into a mounting hole on the
motherboard and its matching mounting hole on the chassis.

7. Repeat Step 5 to insert #6 screws into all mounting holes.

8. Make sure that the motherboard is securely placed in the chassis.

Note: Images displayed are for illustration only. Your chassis or components might
look different from those shown in this manual.

2.3 Processor and Heatsink Installation

Warning: When handling the processor package, avoid placing direct pressure on the LGA lands

(gold contacts) of the CPU or CPU socket. Improper installation or socket misalignment can
cause serious damage to the CPU or motherboard, which may result in RMA repairs. Please
read and follow all instructions thoroughly before installing your CPU and heatsink.

Important:

• Always connect the power cord last, and unplug it before adding, removing, or changing

any hardware components. You must install the processor into the CPU socket before you
install the heatsink.

• If you buy a CPU separately, make sure that you use an Intel-certied multi-directional

heatsink only.

• Install the motherboard into the chassis before you install the CPU heatsink.

• When receiving a motherboard without a pre-intstalled processor, check that a plastic

protective cover is on the CPU socket and none of the socket pins are bent. If they are,
contact your retailer.

• Refer to the Supermicro website for updates on CPU support.

Installing the LGA 1151 Processor

1. Press the load lever down to release the load plate from its locking position.

2. Gently lift the load lever to open the load plate. Remove the plastic protective cover. Do
not touch the CPU socket contacts.

3. Locate the triangle on the CPU and CPU socket, which indicates the location of Pin 1.

Holding the CPU by the edges with your thumb and index nger, align the triangle on

the CPU with the triangle on the socket. The CPU keys (the semi-circle cutouts) may
also be aligned against the socket keys as a guide.

4. Carefully lower the CPU straight down into the socket. Do not drop the CPU on the
socket, or move it horizontally or vertically to avoid damaging the CPU or socket.
Inspect the four corners of the CPU to make sure that the CPU is properly installed.

25

Note: You can only install the CPU in one direction. Make sure it is properly inserted

into the socket before closing the load plate. If it doesn't close properly, do not force
it as it may damage your CPU. Instead, open the load plate again and double-check
that the CPU is properly aligned.

Installing an Active CPU Heatsink with Fan

1. Locate the CPU fan header on the motherboard (FAN1: CPU FAN).

2. Position the heatsink so that its fan wires are closest to the CPU fan header and are not
interfering with other components.

3. Inspect the CPU fan wires to make sure they are routed through the bottom of the
heatsink.

4. Remove the thin layer of protective lm from the heatsink. CPU overheating may occur if

the protective lm is not removed from the heatsink.

5. Apply the proper amount of thermal grease on the CPU. If your heatsink came with a
thermal pad, please ignore this step.

General Guidelines for Optimizing Memory Performance

• Always use DDR4 memory 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. However, to achieve the best

memory performance, a balanced memory population is recommended.
