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 dene 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-dened 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 airow to your system.

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 congure SuperDoctor to provide you with
warnings when the system temperature, CPU temperatures, voltages
and fan speeds go beyond predened thresholds.
1-6 ACPI Features
ACPI stands for Advanced Conguration and Power Interface. The ACPI
specication denes 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 conguration 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-L 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 specications 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 Specication 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.
