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.
A1SRM-LN7F/LN5F 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 A1SRM-LN7F/LN5F Series motherboard supports up to 64GB of DDR3 UDIMM 1600MHz in four memory slots. The C2358 supports up to 16GB at 1333MHz in two slots: DIMMA1 and DIMMA2. Populating these DIMM slots with 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.
A1SRM-LN7F/LN5F Series Motherboard User’s Manual Memory Installation Guidelines (For -2758 Only) When installing memory modules, the DIMM slots should be populated in the following order: DIMMA1, DIMMB1, then DIMMA2, DIMMB2. • Always use DDR3 DIMM modules of the same size, type and speed. Mixing memory modules of different types and speeds is not allowed. • The motherboard will support one DIMM module installed. However, for best memory performance, install DIMM modules in pairs.
Chapter 2: Installation 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.
A1SRM-LN7F/LN5F Series Motherboard User’s Manual 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.

A1SRM-LN7F/LN5F Series Motherboard User’s Manual 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.
Chapter 2: Installation 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.
A1SRM-LN7F/LN5F Series Motherboard User’s Manual Watch Dog Timer Enable Watch Dog Jumper Settings Watch Dog (JWD1) is a system monitor that can be used to enter LAN bypass default set- Jumper Setting tings, reset the system or enter NMI when the Timer expires.
