Chapter 1: Introduction 1-3 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.
A1SAi & A1SRi Series Motherboard User’s Manual 1-5 ACPI Features ACPI stands for Advanced Configuration and Power Interface. The ACPI specification defines a flexible 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.

Chapter 2: Installation 2-3 Memory Support The A1SAi & A1SRi Series motherboard supports up to 64GB of DDR3 ECC Unbuffered SODIMM 1600/1333 MHz in four memory slots. The A1SRi-2358F supports up to 16GB at 1333MHz in two slots: DIMMA1 and DIMMA2. 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: Check the Supermicro website for recommended memory modules.
A1SAi & A1SRi Series Motherboard User’s Manual Populating Memory Modules Note 1: Install the desired number of DIMMs into the memory slots, starting with DIMMA1, then DIMMB1, then DIMMA2, then DIMMB2. Pay attention to the notch along the bottom of the module to prevent incorrect DIMM module installation. DIMMB1/B2 are not available on A1SRi-2358F. Note 2: The motherboard will support one, two, or four DIMM modules. However, for best memory performance, please install DIMM modules in pairs.
Chapter 2: Installation Note: 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. Possible System Memory Allocation & Availability System Device Size Physical Memory Remaining (-Available) (4 GB Total System Memory) Firmware Hub flash memory (System BIOS) 1 MB 3.99 Local APIC 4 KB 3.
A1SAi & A1SRi Series Motherboard User’s Manual 2-4 Motherboard Installation All motherboards have standard mounting holes to fit 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.
Chapter 2: Installation Installing the Motherboard 1. Install the I/O shield into the back of the chassis. 2. Locate the mounting holes on the motherboard. (See the previous page.) 3. Locate the matching mounting holes on the chassis. Align the mounting holes on the motherboard against the mounting holes on the chassis. 4. Install standoffs in the chassis as needed. 5. Install the motherboard into the chassis carefully to avoid damaging other motherboard components. 6.

Chapter 2: Installation 2-7 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 identified 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.
A1SAi & A1SRi Series Motherboard User’s Manual CMOS Clear JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact pads to prevent accidental clearing of CMOS. To clear CMOS, use a metal object such as a small screwdriver to touch both pads at the same time to short the connection. Always remove the AC power cord from the system before clearing CMOS. Note 1: For an ATX power supply, you must completely shut down the system, remove the AC power cord, and then short JBT1 to clear CMOS.
Chapter 2: Installation Watch Dog Timer Enable Watch Dog (JWD1) is a system monitor that can be used to reboot the system when a software application hangs. Close pins 1-2 to reset the system if an application hangs. Close pins 2-3 to generate a non-maskable interrupt signal for the application that hangs. See the table on the right for jumper settings. Watch Dog must also be enabled in the BIOS. VGA Enable Jumper JPG1 allows the user to enable the onboard VGA connector.
A1SAi & A1SRi Series Motherboard User’s Manual 2-8 Onboard Indicators Link Speed LED GbE LAN LEDs There are four GbE LAN ports on the motherboard. Each Gigabit Ethernet LAN port has two LEDs.

See the tables on right for more information.
Chapter 2: Installation Onboard Power LED Onboard PWR LED Indicator LED Settings An Onboard Power LED is located at LED3 on the motherboard. When this LED is on, the system is on. Be sure to turn off the system and unplug the power cord before removing or installing components. See the table on the right for more information. Overheat/PWR Fail/Fan Fail LED An onboard Overheat/PWR Fail/ Fan Fail LED is located at LED8. See the table on the right for more information. LED7 COM1 VGA USB 3.
A1SAi & A1SRi Series Motherboard User’s Manual Unit Identification LED A rear UID LED indicator (LED7) is located next to the Unit Identifier (UID) switch on the I/O backplane. The front panel UID LED is located at pin 7 of the Front Control Panel at JF1. Connect a cable to pin 7 on JF1 for front panel UID LED indication. When you press the UID switch, both rear UID LED and front panel UID LED Indicators will be turned on. Press the UID switch again to turn off both LED Indicators.
Chapter 2: Installation 2-9 SATA Connections Serial ATA Ports Serial ATA Pin Definitions There are up to six Serial ATA ports on the motherboard. I-SATA0/1 support SATA 3.0 connections. I-SATA2~5 are SATA 2.0 ports. These ports provide serial-link signal connections, which are faster than the connections of Parallel ATA. See the table on the right for pin definitions. Note: I-SATA4/5 are not available on the A1SRi-2358F. USB2.0-0/1 LED7 JUIDB1 USB 3.0-3 JPG1 USB3.
