Chapter 1: Introduction

1.2 Processor and Chipset Overview

Built upon the functionality and capability of the AMD Ryzen™ Threadripper™ PRO 3000

Series Processors, up to 64 cores. The M12SWA-TF motherboard o󰀨ers maximum I/O
expendability, energy e󰀩ciency, and data reliability in a 7nm process architecture, and is

optimized for embedded storage solutions, networking applications, or cloud-computing
platforms.

With support of the new microarchitecture 7nm process technology, the M12SWA-TF
drastically increases system performance for a multitude of workstation applications.

The AMD Ryzen™ Threadripper™ PRO 3000 Series Processors support the following
features:

• Leading single threaded and multithreaded performance

• AMD PRO Technologies

• Unrivaled memory bandwidth1

• PCIe® 4.0 support for next-gen GPUs and storage

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

platforms.

1.3 Special Features

This section describes the health monitoring features of the M12SWA-TF 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 o󰀨 (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

M12SWA-TF User's Manual

1.4 System Health Monitoring

This section describes the health monitoring features of the M12SWA-TF 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

PC health monitoring in the BIOS can check the RPM status of the cooling fans. 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 o󰀨 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 2019 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 AST2600 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

su󰀩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 di󰀨erent 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 stando󰀨s click in or are screwed in tightly.

Installing the Motherboard

Note: Always connect the power cord last, and always remove it before adding, removing,

or changing any hardware components. Install the I/O shield into the chassis.

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

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

3. Install stando󰀨s in the chassis as needed.

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

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

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

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

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

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. The spring-loaded Force Frame will raise up after the last screw securing it (#1) is
removed. Gently allow it to lift up to its stopping position.

3. Lift the Rail Frame up by gripping the lift tabs near the front end of the rail frame. While
keeping a secure grip of the Rail Frame, lift it to a position so you can do the next step
of removing the External Cap.

4. Note: The Rail Frame is spring loaded, so keep a secure grip on it as you lift it so it
does not snap up.

6. The CPU Package is shipped from the factory with the Carrier Frame pre-assembled.
Grip the handle of the Carrier Frame/CPU Package assembly from its shipping tray, and

while gripping the handle, align the anges of the Carrier Frame onto the rails of the Rail

Frame so its pins will be at the bottom when the Rail Frame is lowered later.

7. Slide the Carrier Frame/CPU Package downwards to the bottom of the Rail Frame.

Ensure the anges are secure on the rails as you lower it downwards.

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.

8. 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.

9. 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!

10. 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.

11. 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.

12. 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.

13. As illustrated, tighten the four screws down on the heatsink in a diagonal pattern till

it is secured. The heatsink will now be secured and you have nished installing the

processor and heatsink onto the motherboard. Repeat this procedure for any remaining
CPU sockets on the Motherboard.
