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: CPU core, +3.3V, +5V, +/- 12V, +3.3V Stby, +5V Stby, VBAT, HT, Memory PCH Temperature, System Temperature, and CPU 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 and 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 OS environment or used with SuperDoctor II in Linux.

SuperDoctor is used to notify the user of cer tain 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.

Supermicro C7Z270-CG-M 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.

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 two high-speed, 16550 compatible serial communication ports (UARTs). 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 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 com ponents. 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.

Load Plate

2-3

Supermicro C7Z270-CG-M Motherboard User’s Manual

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.

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.

CPU properly installed

into place

Attention! You can only install the CPU inside the socket only 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.

2-5

Supermicro C7Z270-CG-M Motherboard User’s Manual

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.

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.

Attention! CPU overheating may

occur if the protective lm is not

removed from the heatsink.

Thermal Grease

Heatsink Fins

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.

Recommended Supermicro

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.

Towards the edge of the motherboard

The C7Z270-CG-M suppor ts up to 64GB of Unbuffered (UDIMM) non-

ECC DDR4 memor y, up to 3733MHz+ 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.

Notes

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.

Due to memory allocation to system devices, the amount of memory that remains available for operational use will be reduced when 4 GB of RAM is used. The reduction in memory availability is disproportional. See the following table for details.

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 (CPU FAN1, CPU FAN2, SYS FAN1 and SYS FAN2)

Your motherboard has four fan headers. These fans are 4-pin fan headers.

Although pins 1-3 of SYS FAN1 and SYS FAN2 headers are backward compat-

ible 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

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.

Manufacturing Mode

Close pins 2-3 of jumper JPME2 to bypass SPI ﬂash security and force the system to operate in Manufacturing Mode,

allowing the user to ﬂash the system rmware from a host server for system setting modications. Refer to the table

on the right for jumper settings.

Clear CMOS & JBT1

Clear CMOS and JBT1 are 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 metallic conductor such as

a ﬂathead screwdriver. Clear BIOS works the same way but is a push

button switch. This will erase all user settings and revert everything to their factory-set defaults.

PCI-E Slot SMB Enable

Use jumpers I2C1/I2C2 to enable PCI-E SMB (System Management Bus) support to improve system management for the PCI slots. 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.

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.

3-1

Supermicro C7Z270-CG-M Motherboard User’s Manual

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 t0 3000) MHz 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

Answer: The C7Z270-CG-M supports up to 64GB of unbuffered Non-ECC

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 insert a space between "ami.bat" and the lename. The BIOS-ROM-lename will bear the motherboard name (e.g.,

C7Z270CGM) and build version as the extension. For example, "C7Z270CGM". When completed, your system will automatically reboot.

If you choose the .exe le, please run the .exe le under Windows to create the BIOS ash oppy disk. Insert the oppy disk into the system you wish to ash the BIOS. Then, boot the system to the oppy disk. The BIOS utility will automatically ash

the BIOS without any prompts. Please note that this process may take a few minutes to complete. Do not be concerned if the screen is paused for a few minutes.

When the BIOS ashing screen is completed, the system will reboot and will show “Press F1 or F2”. At this point, you will need to load the BIOS defaults. Press <F1> to go to the BIOS setup screen, and press <F9> to load the default settings. Next, press <F10> to save and exit. The system will then reboot.
