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.

1-4 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: VCCP,

VDIMM, 12V, 5VCC, 3.3VCC, VBAT, 5V Dual, and 3.3V AUX. Once a voltage

becomes unstable, a warning is given, or an error message is sent to the screen.

Environmental Temperature Control

This motherboard came with a passive heatsink built in. Please follow the instruc-

tions given in your system design guide or your system user manual to provide

adequate airow to your system. The onboard BaseBoard Management Controller

(BMC) monitors CPU, memory and motherboard environment temperatures for fan

control and PC health management.

Note: To avoid possible system overheating, please be sure to provide

adequate airow to your system.

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.

1-11

A1SRM-LN7F/LN5F Series Motherboard User’s Manual

1-5 ACPI Features

ACPI stands for Advanced Conguration and Power Interface. The ACPI specica-

tion 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. A1SRM Series motherboard supports S0 and S5 only.

1-6 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.

Note 1: The A1SRM-LN7F/LN5F Series motherboard alternatively sup-

ports a 4-pin 12V DC input power supply for embedded applications. The

12V DC input is recommended up to 14A by design, therefore it provides

up to 168W power input to the motherboard. Please keep onboard power

use within the power limits specied above. Over-current DC power use

may cause damage to the motherboard!

Note 2: Do not use the 4-pin DC power at JPW2 when the 24-pin ATX

power at JPW1 is connected to the power supply. Do not plug in both

JPW2 and JPW1 at the same time.

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.

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.

Installing DIMM Memory Modules

1. Align the key on the bottom of the DIMM module against the key on the mem-

ory slot. Take note of the notches on the side of the DIMM module, and of the

locking clips on the socket to avoid causing damage.

Socket Key

2. Install the DIMM module straight down into the socket until it is securely seat-

ed in the socket. The side clips will automatically lock the module into place.

Locking Clip

Removing Memory Modules

Reverse the steps above to remove the DIMM modules from the motherboard.

Chapter 2: Installation

2-4 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 fas-

teners, 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.

This section provides brief descriptions and pin-out denitions for onboard headers

and connectors. Be sure to use the correct cable for each header or connector.

ATX PWR, DC PWR and HDD PWR
Connectors (JPW1, JPW2, J4)

The 24-pin ATX power connector header

(JPW1) is used to provide power to the

motherboard. JPW2 is the 12V DC power

connector that provides alternative power

for special enclosure when the 24-pin

ATX power is not in use. The 4-pin HDD

power connector J4 provides power to

onboard HDD devices.

Fan Headers (Fan 1 ~ Fan 3)

The A1SRM-LN7F/LN5F Series 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 you use 4-pin fans

to take advantage of the fan speed control via

Pulse Width Modulation through the BMC. This

allows the fan speeds to be automatically ad-

justed 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 intru-

sion when the chassis is opened.

2-7 Jumper Settings

Explanation of Jumpers

To modify the operation of the mother-

board, 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.

VGA Enable

Jumper JPG1 allows the user to enable the

onboard VGA connector. The default setting

is pins 1-2 to enable the connection. See the

table on the right for jumper settings.

CMOS Clear

JB T1 is used to clear CM OS . In st ea d of pins, thi s "j um pe r" consists of co nt ac t pa ds

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 connec-

tion. 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.

Note 2: Be sure to remove the onboard CMOS Battery before you short

JBT1 to clear CMOS.

Note 3: Clearing CMOS will also clear all passwords.

hardware components.

Before Power On

1. Make sure that the 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 add-on cards.

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.

No Video

1. If the power is on, but you have no video, you will need to remove all the add-

on cards and cables rst.

3-1

A1SRM-LN7F/LN5F Series Motherboard User’s Manual

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 ECC or Non-ECC DDR3 UDIMM (1.5V, 1.35V) 1600/1333

MHz memory recommended by Supermicro. Also, it is required 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, nor 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.

Losing the System’s Setup Conguration

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 1-6

for details on recommended power supplies.

2. The battery on your motherboard may be old. Check to verify that it still sup-

plies ~3VDC. If it does not, replace it with a new one.

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

vendor for repairs.

3-2

Chapter 3: Troubleshooting

Chapter 4: AMI BIOS

Chapter 4

BIOS

4-1 Introduction

This chapter describes the AMI BIOS setup utility for the A1SRM-LN7F/LN5F Series

motherboard. The ROM BIOS is stored in a Flash EEPROM and can be easily

updated. This chapter describes the basic navigation of the AMI BIOS setup utility

setup screens.

Note: For AMI BIOS Recovery, please refer to the UEFI BIOS Recovery

Instructions in Appendix C.

Starting BIOS Setup Utility

To enter the AMI BIOS setup utility screens, press the <Delete> key while the

system is booting up.

Note: In most cases, the <Delete> key is used to invoke the AMI BIOS

setup screen. There are a few cases when other keys are used, such as

<F1>, <F2>, etc.

Each main BIOS menu option is described in this manual. The Main BIOS setup

menu screen has two main frames. The left frame displays all the options that can

be congured. Grayed-out options cannot be congured. Options in blue can be

congured by the user. The right frame displays the key legend. Above the key

legend is an area reserved for a text message. When an option is selected in the

left frame, it is highlighted in white. Often a text message will accompany it. (Note:

the AMI BIOS has default text messages built in. Supermicro retains the option to

include, omit, or change any of these text messages.)

The AMI BIOS setup utility uses a key-based navigation system called "hot keys".

Most of the AMI BIOS setup utility "hot keys" can be used at any time during the

setup navigation process. These keys include <F1>, <F4>, <Enter>, <ESC>, arrow

keys, etc.

Note: Options printed in Bold are default settings.

How To Change the Conguration Data

The conguration data that determines the system parameters may be changed by

entering the AMI BIOS setup utility. This setup utility can be accessed by pressing

<Del> at the appropriate time during system boot.
