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

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.

Load Plate

Load Lever

24

Chapter 2: Installation

2. Gently lift the load lever to open the load plate. Remove the plastic cap.

3. Use your thumb and your index nger to hold the CPU at the north center edge and the
South center edge of the CPU.

North Center Edge

South Center Edge

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.

place

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.

26

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.

2.8 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

at right 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 and "Open" means the
jumper is off the pins.

Troubleshooting

3.1 Troubleshooting Procedures

Use the following procedures to troubleshoot your system. If you have followed all of the
procedures below and still need assistance, refer to the ‘Technical Support Procedures’ and/
or ‘Returning Merchandise for Service’ section(s) in this chapter. Always disconnect the AC
power cord before adding, changing or installing any non hot-swap hardware components.

Before Power On

1. Check that the power LED on the motherboard is on.

2. Make sure that the power connector is connected to your power supply.

3. Make sure that no short circuits exist between the motherboard and chassis.

4. Disconnect all cables from the motherboard, including those for the keyboard and
mouse.

5. Remove all add-on cards.

6. Install a CPU, a heatsink*, and connect the internal speaker and the power LED to the
motherboard. Check all jumper settings as well. (Make sure that the heatsink is fully
seated.)

7. Use the correct type of onboard CMOS battery (CR2032) as recommended by the
manufacturer. To avoid possible explosion, do not install the CMOS battery upside down.

No Power

1. Make sure that no short circuits exist between the motherboard and the chassis.

2. Verify that all jumpers are set to their default positions.

3. Check that the 115V/230V switch on the power supply is properly set.

4. Turn the power switch on and off to test the system.

5. 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.

49

C7C232-CB-ML User's Manual

No Video

1. If the power is on but you have no video, remove all the add-on cards and cables.

2. Use the speaker to determine if any beep codes exist. Refer to Appendix A for details on
beep codes.

Note: If you are a system integrator, VAR or OEM, a POST diagnostics card is recom­mended. For I/O port 80h codes, refer to Appendix B.

System Boot Failure

If the system does not display POST (Power-On-Self-Test) 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

contacting both pads on the CMOS Clear Jumper (JBT1). Refer to 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

1. Make sure that the DIMM modules are properly and fully installed.

2. Conrm that you are using the correct memory. Also, it is recommended that you use
the same memory type and speed for all DIMMs in the system. See Section 2.4 for
memory details.

3. Check for bad DIMM modules or slots by swapping modules between slots and noting
the results.

4. Check the power supply voltage 115V/230V switch.

50

Chapter 3: Troubleshooting

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 1.5 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.

3. 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: Refer to the product page on our website at http:\\www.supermicro.com for
memory and CPU support and updates.

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
the system. Make sure that all power connectors are connected. Please refer to our
website for more information on the minimum power requirements.

6. Proper software support: Make sure that the correct drivers are used.

B. If the system becomes unstable before or during OS installation, check the following:

1. Source of installation: Make sure that the devices used for installation are working
properly, including boot devices such as CD/DVD and CD/DVD-ROM.

2. Cable connection: Check to make sure that all cables are connected and working
properly.

51

C7C232-CB-ML User's Manual

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 a 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.

Chapter 3: Troubleshooting

3.2 Technical Support Procedures

Before contacting Technical Support, please take the following steps. Also, note that as a

motherboard manufacturer, we do not sell directly to end-users, so it is best to rst check with

your distributor or reseller for troubleshooting services. They should know of any possible

problem(s) with the specic system conguration that was sold to you.

1. Please review the ‘Troubleshooting Procedures’ and 'Frequently Asked Questions'
(FAQs) sections in this chapter or see the FAQs on our website before contacting
Technical Support.

2. BIOS upgrades can be downloaded from our website. Note: Not all BIOS can be

ashed depending on the modications to the boot block code.

3. If you still cannot resolve the problem, include the following information when contacting
us for technical support:

• Motherboard model and PCB revision number

• BIOS release date/version (this can be seen on the initial display when your system rst

boots up)

• System conguration

An example of a Technical Support form is posted on our website.

C7C232-CB-ML User's Manual

3.3 Frequently Asked Questions

Question: What type of memory does my motherboard support?

Answer: The motherboard supports up to 64 GB of DDR4 2133MHZ ECC UDIMM memory.

See Section 2.4 for details on installing memory.

Question: How do I update my BIOS?

Answer: It is recommended that you do not upgrade your BIOS if you are not experiencing

any problems with your system. Updated BIOS les are located on our website at http://www.

supermicro.com. Please check our BIOS warning message and the information on how to

update your BIOS on our website. Select your motherboard model and download the BIOS

le to your computer. Also, check the current BIOS revision to make sure that it is newer
than your BIOS before downloading. You can choose from the zip le and the .exe le. If
you choose the zip BIOS le, please unzip the BIOS le onto a bootable USB device. Run
the batch le using the format FLASH.BAT lename.rom from your bootable USB device to
ash the BIOS. Then, your system will automatically reboot.

Question: Why can't I turn off the power using the momentary power on/off switch?

Answer: The instant power off function is controlled in BIOS by the Power Button Mode

setting. When the On/Off feature is enabled, the motherboard will have instant off capabilities
as long as the BIOS has control of the system. When the Standby or Suspend feature is

enabled or when the BIOS is not in control such as during memory count (the rst screen

that appears when the system is turned on), the momentary on/off switch must be held for
more than four seconds to shut down the system. This feature is required to implement the
ACPI features on the motherboard.

Chapter 4

BIOS

4.1 Introduction

This chapter describes the AMIBIOS™ Setup utility for the C7C232-CB-ML motherboards.

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 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>, <F2>, <F3>, <F4>, <Enter>, <ESC>, <Arrow> keys, etc.) can be used at
any time during the setup navigation process.

A.1 BIOS Error POST (Beep) Codes

During the POST (Power-On Self-Test) routines, which are performed each time the system
is powered on, errors may occur.

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

Fatal errors are those which will not allow the system to continue the boot-up procedure. 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.

BIOS Beep (POST) Codes

Beep Code Error Message Description

1 beep Refresh Circuits have been reset (Ready to power up)

5 short, 1 long Memory error No memory detected in system

A.2 Additional BIOS POST Codes

The AMI BIOS supplies additional checkpoint codes, which are documented online at http://

www.supermicro.com/support/manuals/ ("AMI BIOS POST Codes User's Guide").

When BIOS performs the Power On Self Test, it writes checkpoint codes to I/O port 0080h.
If the computer cannot complete the boot process, a diagnostic card can be attached to the
computer to read I/O port 0080h (Supermicro p/n AOC-LPC80-20).
