1-4 Special Features

Recovery from AC Power Loss

Basic I/O System (BIOS) provides a setting for you to determine 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 a power-on state. See the Advanced BIOS
Setup section to change this setting. The default setting is Last State.

1-5 PC Health Monitoring

This section describes the PC health monitoring features of the board.
All have an onboard System Hardware Monitoring chip that supports PC
health monitoring. An onboard voltage monitor will scan these onboard
voltages continuously: +1.8V, +3.3V, +5V, +/- 12V, +3.3V Stby, +5V
Stby, VBAT, HT, Memory Temperature, PCH Temperature, and System
Temperature. 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.

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 via SIO.

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.

1-4

Chapter 1: Introduction

System Resource Alert

This feature is available when the system is used with SuperDoctor 5

in the Windows and Linux operating systems. SuperDoctor is used to

notify the user of certain system events. For example, you can also

congure SuperDoctor to provide you with warnings when the system

temperature, CPU temperatures, voltages, and fan speeds go beyond

predened thresholds.

1-6 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 PC system, including its hardware, operating system and

application software. This enables the system to automatically turn on

and off peripherals such as CD-ROMs, 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 7, Windows 8, and Windows 2008 Operating Systems.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will

start to blink to indicate that the CPU is in suspend mode. When the user

presses any key, the CPU will wake up, and the LED will automatically

stop blinking and remain on.

1-5

Supermicro C7C242-CB-M/MW Motherboard User’s Manual

1-7 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 or overclocked processors.

This motherboard accommodates 24-pin ATX power supplies. Although

most power supplies generally meet the specications required by the

CPU, some are inadequate. In addition, the 12V 8-pin power connector
located at JPW2 is also required to ensure adequate power supply to the
system. Also your power supply must supply 1.5A for the Ethernet ports.

Attention! To prevent damage to the power supply or mother­board, please use a power supply that contains a 24-pin and a
8-pin power connectors. Be sure to connect these connectors to
the 24-pin (JPW1) and the 8-pin (JPW2) power connectors on the
motherboard.

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

that meets ATX power supply Specication 2.02 or above. It must also

be SSI compliant. (For more information, please refer to the web site
at http://www.ssiforum.org/). Additionally, 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.

1-8 Super I/O

The Super I/O supports one high-speed, 16550 compatible serial com­munication port (UART). This UART includes a 16-byte send/receive FIFO,
a programmable baud rate generator, complete modem control capability
and a processor interrupt system. The UART provides legacy speed with
a 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 an SMI or SCI function pin. It also
features auto power management to reduce power consumption.

2-2 Static-Sensitive Devices

Electrostatic-Discharge (ESD) can damage electronic components. 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 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 your computer chassis provides
excellent conductivity 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 board, make sure that the person handling it
is static protected.

2-2

Chapter 2: Installation

2-3 Processor and Heatsink Installation

Attention! 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 system board into the chassis before
you install the CPU heatsink.

When receiving a server board 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 small triangle marker on the CPU to its corresponding tri­angle marker on the load bracket. 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.)

2-4

Chapter 2: Installation

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.

8. Close the load plate with the CPU inside the socket. Lock the "Close

1st" lever rst, then lock the "Open 1st" lever second. Gently push

the load levers down to the lever locks.

The C7C242-CB-M/MW suppor ts up to 64GB of Unbuf fered (UDIMM),
ECC/Non-ECC DDR4 memory up to 2666MHz in four 288-pin memory

slots. Populating these DIMM modules with a pair of memory modules
of the same type and same size will result in interleaved memory, which
will improve memory performance.

Note: Be sure to use memory modules of the same type, same
speed, same frequency on the same motherboard. Mixing of mem­ory modules of different types and speeds is not allowed.

2-9

Supermicro C7C242-CB-M/MW Motherboard User’s Manual

Memory Population Guidelines

When installing memory modules, the DIMM slots should be populated in
the following order: DIMMA2, DIMMB2, then DIMMA1, DIMMB1.

• Always use DDR4 DIMM modules of the same size and speed.

• Mixed DIMM speeds can be installed. However, all DIMMs will run at the
speed of the slowest DIMM.

2-5 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
motherboard and 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. Then use a screwdriver
to secure the motherboard onto the motherboard tray.

Fan Headers

Your motherboard has three fan head­ers. These fans are 4-pin fan headers.
Although pins 1-3 of the fan headers are
backward compatible with the traditional
3-pin fans, we recommend the use 4-pin
fans to take advantage of the fan speed
control. This allows the fan speeds to
be automatically adjusted based on the
motherboard temperature. Refer to the

table on the right for pin denitions.

Chassis Intrusion (JL1)

A Chassis Intrusion header is located at
JL1 on the motherboard. Attach the ap­propriate cable from the chassis to inform
you of a chassis intrusion when the chassis
is opened.

2-8 Jumper Settings

Explanation of Jumpers

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.

Note: On two-pin jumpers, "Closed"
means the jumper is on, and "Open"
means the jumper is off the pins.

JTPM1:

JBT1 & JCMOS

JBT1 is used to clear the saved system setup conguration stored in the

CMOS chip. To clear the contents of the CMOS usng JBT1, short the two

pads of JBT1 with a metallic conductor such as a athead screwdriver.

JCMOS works similarly to JBT1. Close pins 2 and 3 of JCMOS to clear
CMOS. This will erase all user settings and revert everything to their
factory defaults.

Watch Dog Timer Enable/Disable

Watch Dog (JWD1) is a system monitor
that can reboot the system when a soft­ware application hangs. Close pins 1 and
2 to reset the system if an application
hangs. Close pins 2 and 3 to generate a
non-maskable interrupt signal for the ap­plication that hangs. Refer to the table on
the right for jumper settings.

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 hardware components.

Before Power On

1. Make sure that the Standby PWR LED is not on. (Note: If it is on,
the onboard power is on. Be sure to unplug the power cable before
installing or removing the components.)

2. Make sure that there are no short circuits between the motherboard
and chassis.

3. Disconnect all ribbon/wire cables from the motherboard, including
those for the keyboard and mouse. Also, be sure to remove all add­on cards.

4. Install a CPU and heatsink (be sure that it is fully seated) and then
connect the chassis speaker and the power LED to the mother­board. Check all jumper settings as well.

No Power

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

2. Make sure that all jumpers are set to their default positions.

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

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

3-1

Supermicro C7C242-CB-M/MW Motherboard User’s Manual

5. The battery on your motherboard may be old. Check to make sure
that it still supplies ~3VDC. If it does not, replace it with a new
one.

No Video

1. If the power is on, but you have no video--in this case, you will

need to remove all the add-on cards and cables rst.

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

3. Remove all memory modules and turn on the system. (If the

alarm is on, check the specications of memory modules, reset the

memory or try a different one.)

Memory Errors

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

2. You should be using unbuffered Non-ECC DDR4 (up to 2666MHz)
memory recommended by the manufacturer. Also, it is recom­mended that you use the memory modules of the same type and
speed for all DIMMs in the system. Do not use memory modules
of different sizes, different speeds and different types on the same
motherboard.

3. Check for bad DIMM modules or slots by swapping modules be­tween slots to see if you can locate the faulty ones.

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

When the System is Losing the Setup Configuration

1. Please be sure to use a high quality power supply. A poor quality
power supply may cause the system to lose CMOS setup informa­tion. Refer to Section 1-7 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.

3-2

Chapter 3: Troubleshooting

3. If the above steps do not x the Setup Conguration problem,

contact your vendor for repairs.

3-2 Technical Support Procedures

Before contacting Technical Support, please make sure that you have
followed all the steps listed below. Also, note that as a motherboard
manufacturer, Supermicro does 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 go through the ‘Troubleshooting Procedures’ and 'Frequently
Asked Question' (FAQ) sections in this chapter or see the FAQs on
our website (http://www.supermicro.com/support/faqs/) before
contacting Technical Support.

2. BIOS upgrades can be downloaded from our website at (http://

www.supermicro.com/support/bios/).

Note: Not all BIOS can be ashed. Some cannot be ashed; it

depends on the boot block code of the BIOS.

3. If you've followed the instructions above to troubleshoot your
system, and still cannot resolve the problem, then contact Supermi­cro's technical support and provide them with the following infor­mation:

• 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 on our website at (http://

www.supermicro.com/support/contact.cfm).

4. Distributors: For immediate assistance, please have your account

number ready when placing a call to our technical support depart-

ment. We can be reached by e-mail at [e-mail],

by phone at: [phone], option 2, or by fax at (408)503-

8019.

Supermicro C7C242-CB-M/MW Motherboard User’s Manual

3-3 Frequently Asked Questions

Question: What type of memory does my motherboard support?

Answer: The C7C242-CB-M/MW supports up to 32GB of unbuffered Non-

ECC U-DIMM DDR4. See Section 2-4 for details on installing memory.

Question: How do I update my BIOS?

Answer: We do NOT recommend that you 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/support/bios/.
Please check our BIOS warning message and the information on how
to update your BIOS on our web site. Select your motherboard model
and download the BIOS ROM le to your computer. Also, check the cur­rent BIOS revision to make sure that it is newer than your BIOS before

downloading. You may choose the zip le or the .exe le. If you choose
the zipped BIOS le, please unzip the BIOS le onto a bootable device
or a USB pen/thumb drive. To ash the BIOS, run the batch le named
"ami.bat" with the new BIOS ROM le from your bootable device or USB

pen/thumb drive. Use the following format:

F:\> ami.bat BIOS-ROM-lename.xxx <Enter>

Note: Always use the le named “ami.bat” to update the BIOS,
and inse r t a spa ce be twe en "ami.bat" and the l ename. The BI­OS - ROM-  lenam e will bea r th e motherbo a r d name (i .e., CZ39 0)

Appendix A

BIOS Error 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 with bootup. The error messages normally appear on the screen.

Fatal errors will not allow the system to continue to bootup. 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 numbers on the fatal error list correspond to the number of
beeps for the corresponding error.

Appendix C: UEFI BIOS Recovery

Appendix C

UEFI BIOS Recovery Instructions

Attention! Do not upgrade the BIOS unless your system has a
BIOS-related issue. Flashing the wrong BIOS can cause irreparable
damage to the system. In no event shall Supermicro be liable for
direct, indirect, special, incidental, or consequential damages aris­ing from a BIOS update. If you need to update the BIOS, do not
shut down or reset the system while the BIOS is updating to avoid
possible boot failure.

C-1 An Overview to the UEFI BIOS

The Unied Extensible Firmware Interface (UEFI) specication provides a

software-based interface between the operating system and the platform

rmware in the pre-boot environment. The UEFI specication supports

an architecture-independent mechanism for add-on card initialization to

allow the UEFI OS loader, which is stored in the add-on card, to boot
up the system. UEFI offers a clean, hands-off control to a computer

system at bootup.

C-2 How to Recover the UEFI BIOS Image

A UEFI BIOS ash chip consists of a recovery BIOS block and a main
BIOS block (a main BIOS image). The recovery block contains critical

BIOS codes, including memory detection and recovery codes for the user

to ash a healthy BIOS image if the original main BIOS image is cor­rupted. When the system power is turned on, the recovery block codes
execute rst. Once this process is complete, the main BIOS code will
continue with system initialization and the remaining POST (Power-On
Self-Test) routines.

Note: Follow the BIOS Recovery instructions below for BIOS recov­ery when the main BIOS boot crashes. However, when the BIOS

boot block crashes, you will need to follow the procedures to make
a Returned Merchandise Authorization (RMA) request.

C-1

Supermicro C7B360-CB-M/MW Motherboard User’s Manual

C-3 To Recover the Main BIOS Block Using a USB­Attached Device

This feature allows the user to recover a BIOS image using a USB-

attached device without additional utilities used. A USB ash device such

as a USB Flash Drive, or a USB CD/DVD ROM/RW device can be used for

this purpose. However, a USB Hard Disk drive cannot be used for BIOS

recovery at this time.

To perform UEFI BIOS recovery using a USB-attached device, follow the

instructions below.

1. Using a different machine, copy the "Super.ROM" binary image le

into the disc Root "\" Directory of a USB device or a writeable CD/
DVD.

Note: If you cannot locate the "SUPER.ROM" le in your driver
disk, visit our website at www.supermicro.com to download the
BIOS package. Extract the BIOS binary image into a USB ash
device and rename it "SUPER.ROM" for the BIOS recovery use.

2. Insert the USB device that contains the new BIOS image ("SUPER.
ROM") into any available USB port. Be sure the le is saved in the
very top (root) folder.

3. With the USB device inserted, power on the system.

4. After locating the new BIOS binary image, the system will enter the

BIOS Recovery menu as shown below.
