Chapter 1: Introduction

1.2 Processor and Chipset Overview

Built upon the functionality and capability of the Intel E3-1200 V5 series processors (Socket
LGA 1151) and the Intel C232 PCH, the C7C232-CB-ML motherboard offers maximum I/O

expandability, energy efciency, and data reliability in a 14-nm process architecture and is

optimized for desktop solutions.

The Intel E3-1200 V5 and PCH C232 platform supports the following features:

• ACPI Power Management Logic Support, Rev. 4.0a

• Intel Turbo Boost Technology

• Congurable TDP (cTDP) and Lower-Power Mode

• Adaptive Thermal Management/Monitoring

• PCI-E 3.0 and SATA 3.0 w/transfer rates of up to 6 Gb/s

• Intel Trusted Execution Technology (Intel TXT)

• Intel Virtualization Technology for Directed I/O (Intel VT-d)

1.3 Special Features

This section describes the health monitoring features of the C7C232-CB-ML 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

C7C232-CB-ML User's Manual

1.4 System Health Monitoring

This section describes the health monitoring features of the C7C232-CB-ML 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. 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 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 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.

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 8/R2, and 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 (ITE8732F) 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 two high-speed, 16550 compatible serial communication ports
(UARTs), one of which supports serial infrared communication. Each UART includes a 16-byte
send/receive FIFO, a programmable baud rate generator, complete modem control capability
and a processor interrupt system. Both UARTs provide 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).

19

C7C232-CB-ML User's Manual

1.8 Advanced Power Management

The following new advanced power management features are supported by the motherboard.

Intel® Intelligent Power Node Manager (IPNM)

Available when the Supermicro Power Manager (SPM) is installed, Intel's Intelligent Power
Node Manager (IPNM) provides your system with real-time thermal control and power

management for maximum energy efciency. Although IPNM Specication Version 2.0/3.0

is supported by the BMC (Baseboard Management Controller), your system must also have

IPNM-compatible Management Engine (ME) rmware installed to use this feature.

Note: Support for IPNM 2.0/3.0 support is dependent on the power supply used in
the system.

Management Engine (ME)

The Management Engine, which is an ARC controller embedded in the IOH (I/O Hub), provides
Server Platform Services (SPS) to your system. The services provided by SPS are different
from those provided by the ME on client platforms.

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.

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:

• 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 to release the load plate, which covers the CPU socket, from its
locking position.

4. Align the CPU key that is the semi-circle cutouts against the socket keys. Once it is
aligned, carefully lower the CPU straight down into the socket. (Do not drop the CPU on
the socket. Do not move the CPU horizontally or vertically.

25

C7C232-CB-ML User's Manual

5. Do not rub the CPU against the surface or against any pins of the socket to avoid
damaging the CPU or the socket.

6. With the CPU inside the socket, inspect the four corners of the CPU to make sure that
the CPU is properly installed.

7. Use your thumb to gently push the load lever down to the lever lock.

Note: You can only install the CPU inside the socket in one direction. Make sure that

it is properly inserted into the CPU 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 aligned properly.

Installing an Active CPU
Heatsink with Fan

1. Locate the CPU fan power connector on
the motherboard. (Refer to the layout on
the right for the CPU Fan location.)

2. Position the heatsink so that the heatsink
fan wires are closest to the CPU fan
power connector and are not interfered
with other components.

Chapter 2: Installation

Thermal Grease

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

4. Remove the thin layer of the protective

lm from the heatsink.

Important: CPU overheating may oc-

cur if the protective lm is not removed

from the heatsink.

5. Apply the proper amount of thermal
grease on the CPU.

Note: If your heatsink came with a ther­mal pad, please ignore this step.

6. If necessary, rearrange the wires to
make sure that the wires are not pinched
between the heatsink and the CPU. Also
make sure to keep clearance between the

fan wires and the ns of the heatsink.

7. Align the four heatsink fasteners with
the mounting holes on the motherboard.
Gently push the pairs of diagonal
fasteners (#1 & #2, and #3 & #4) into
the mounting holes until you hear a click.
Also, make sure to orient each fastener
so that the narrow end of the groove is
pointing outward.

8. Repeat step 7 to insert all four heatsink
fasteners into the mounting holes.

9. Once all four fasteners are securely
inserted into the mounting holes, and
the heatsink is properly installed on the
motherboard, connect the heatsink fan
wires to the CPU fan connector.

28

Removing the Heatsink

Note: We do not recommend that

the CPU or the heatsink be removed.
However, if you do need to remove the
heatsink, please follow the instructions
below to remove the heatsink and to
prevent damage done to the CPU or
other components.

Active Heatsink Removal

1. Unplug the power cord from the power
supply.

Chapter 2: Installation

Unplug the

PWR cord

2. Disconnect the heatsink fan wires from
the CPU fan header.

3. Gently press on the fastener cap, turn it
counterclockwise to make a 1/4 (900) turn
and pull the fastener upward to loosen it.

4. Repeat step 3 to loosen all fasteners from
the mounting holes.

5. With all fasteners loosened, remove the
heatsink from the CPU.

2.4 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 C7C232-CB-ML supports up to 32GB of DDR4 Non-ECC UDIMM 2133MHz memory.
Populating these DIMM modules with a pair of 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.

DIMM Module Population Sequence

When installing memory modules, the DIMM slots must be populated in the following order:

DIMMB2, DIMMA2, then DIMMB1, DIMMA1. The blue slots must be populated rst.
