Chapter 1: Introduction
1.2 Processor and Chipset Overview
Built upon the functionality and capability of the Intel Xeon E-2100, 8th Gen Core i3, Pentium,
and Celeron processor and the C246 chipset, this motherboard provides superb system
performance, efcient power management, and a rich feature set based on cutting edge
technology to address the needs of next-generation computer users. This motherboard is
optimized for medical and surveillance devices.
The Intel Xeon E-2100, 8th Gen Core i3, Pentium, and Celeron processor and the C246
chipset support the following features:
• PCI-E 3.0 M.2
• Intel Hyper-Threading, Intel VT-D, VT-x
• TSX-NI, AES, SGX
• Intel Turbo Boost Technology
• Intel Rapid Storage Technology
• 64GB DDR4 Very Low Prole UDIMM memory support with speeds of up to 2666MHz
1.3 Special Features
This section describes the health monitoring features of the B2SC1-CPU 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
Super B2SC1-CPU User's Manual
1.4 System Health Monitoring
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. The user
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 chip can check the RPM status of a cooling fan. The CPU and
chassis fans are controlled by the BIOS 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 provide adequate airow to your
system.
System Resource Alert
This feature is available when used with SuperDoctor 5® in the Windows®operating system or
in the Linux environment. 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
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®Server 2012/2016 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 transmission is present, you may choosr 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 AST2500 provides high-speed, 16550 compatible serial communication ports
(UART), which support serial infrared communication. The UART includes send/receive FIFO,
a programmable baud rate generator, complete modem control capability, and a processor
interrupt system. The UART provides legacy speed with baud rate of up to 115.2 Kbps.
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 components. To avoid damaging
your motherboard and your system, 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.

19
Chapter 2: Installation
2.2 Processor and Heatsink Installation
Warning: When handling the processor package, avoid placing direct pressure on the label
area of the fan.
Important:
• 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 Intel-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 LGA1151 Processor
1. Press the load lever down to release the load plate from its locking position.

Super B2SC1-CPU User's Manual
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.
