latest technologies making it another standout in the long line of ASUS
quality server motherboards!

The NR-LSR supports the Intel
coupled with the ServerWorks® Grand Champion Low End (GCLE)
SystemSet to deliver a reliable and high performance server platform.

The NR-LSR is pre-installed in the ASUS AP160R-S 1U barebone
server system.

The figure below shows the top view of the NR-LSR motherboard installed

1.2 Special features

1.2.1 Product highlights

Latest processor technology

The NR-LSR motherboard supports the Intel
478-pin surface mount ZIF socket. The processor features the Intel
NetBurst™ micro-architecture that includes hyper-pipelined technology, a
rapid execution engine, a 400MHz system bus, and an execution trace cache
to offer a significant increase in performance. See page 2-4 for more
information.

Pentium® 4 processor via a

®

DDR memory support

Employing the Double Data Rate (DDR) memory technology, the NR-LSR
motherboard supports up to 8GB of system memory using PC2100/1600
registered ECC DDR DIMMs. The ultra-fast 200MHz memory bus doubles
the speed of the PC100 SDRAM to deliver the required bandwidth for the
latest 3D graphics, multimedia, and Internet applications. See page 2-10.

Dual-channel Ultra-160/320 SCSI

The LSI® 53C1010R 64-bit/66MHz PCI SCSI controller is onboard to
support dual-channel Ultra-160 SCSI connectors that provide high-speed
data transfer interfaces.

Advanced 64-bit PCI-X slots

The 64-bit/133MHz expansion slot onboard supports a proprietary riser
card with two PCI-X slots (on both sides). The PCI-X slots maximize I/O
bandwidth for the next generation 64-bit PCI-X cards that support
133/100MHz bus. The PCI-X specification 1.0a allows full peer-to-peer
transactions between PCI buses and provides options for intelligent I/O
and server management cards.

Onboard LAN

The motherboard comes with the Intel® 82550PM Fast Ethernet controller
and the Intel® 82544GC Gigabit Ethernet controller to support the latest
LAN technologies.

1-2

Chapter 1: Product introduction

Onboard VGA

The ATI Rage-XL PCI-based VGA controller integrates an 8MB display
SDRAM to provide onboard video solution.

Integrated IDE bridge

The motherboard includes two connectors to support an IDE board with
dual-channel bus master IDE connectors. The IDE connectors support
Ultra DMA 100/66/33, PIO modes 3 & 4 devices.

ASUS NR-LSR motherboard user guide

1.2.2 Value-added solutions

Temperature, fan, and voltage monitoring

The CPU temperature is monitored by the ASUS ASIC to prevent
overheating and damage. The system fan rotations per minute (RPM) is
monitored for timely failure detection. The system voltage levels are
monitored to ensure stable supply of current for critical components.

Dual function power switch

While the system is ON, pressing the power switch for less than 4 seconds
puts the system to sleep mode or to soft-off mode, depending on the BIOS
setting. Pressing the power switch for more than 4 seconds lets the
system enter the soft-off mode regardless of the BIOS setting.

Remote Ring In

This feature allows the system to wake up remotely through an internal or
external modem, if present.

Wake-Up support

The motherboard includes Wake-On-LAN, Wake-On-Ring, and BIOS
Wake-Up features.

Server management

The motherboard comes with an ASMC connector that supports the
optional ASMC-HE/ME/LE card to comply with server reliability, availability,
and serviceability requirements. Remote management response via
remote diagnostics and troubleshooting still works even when the
operating system has stopped functioning.

ACPI ready

The Advanced Configuration power Interface (ACPI) provides more energy
saving features for operating systems that support OS Direct Power
Management (OSPM).

Concurrent PCI

This feature allows multiple PCI transfers from PCI master buses to the
memory and processor.

1-4

Chapter 1: Product introduction

Auto fan off

The system fans power off automatically when the system is in sleep
mode. This feature reduces both power consumption and system noise.

Chassis intrusion detection

The motherboard supports chassis intrusion monitoring through the ASUS
ASIC. A chassis intrusion event is retained in the system memory for more
protection.

Smart BIOS

The 4Mbit firmware gives an easy-to-use interface that provides more
control and protection to the motherboard. The BIOS has a boot block
write protection and HD/SCSI/MO/ZIP/CD/Floppy boot selection, and is
Year 2000 certified.

Compliance

Both the BIOS and the hardware levels of the motherboard meet the
stringent requirements for SDG 2.0 certification. The new SDG 2.0
requirements for systems and components are based on the following
high-level goals: support for Plug-and-Play compatibility and power
management for configuring and managing all system components, 32-bit
device drivers, and installation procedures for Windows NT/2000/XP.
Color-coded connectors and descriptive icons make identification easy as
required by the PC ‘99 specification.

ASUS NR-LSR motherboard

2.1 Motherboard installation

Before you install the motherboard, study the configuration of your chassis
to ensure that the motherboard fits into it. The NR-LSR uses the extended
ATX form factor that measures 12 x 12 inches (30.5 x 30.5 cm).

Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so may cause you physical injury and
damage motherboard components.

2.1.1 Placement direction

When installing the motherboard, make sure that you place it into the
chassis in the correct orientation. The edge with external ports goes to the
rear part of the chassis as indicated in the image below.

2.1.2 Screw holes

Place eight (8) screws into the holes indicated by circles to secure the
motherboard to the chassis.

Do not overtighten the screws! Doing so may damage the
motherboard.

Place this side towards
the rear of the chassis

2.3 Before you proceed

Take note of the following precautions before you install motherboard
components or change any motherboard settings.

1. Unplug the power cord from the wall socket before touching any
component.

2. Use a grounded wrist strap or touch a safely grounded object or to
a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity.

3. Hold components by the edges to avoid touching the ICs on them.

4. Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.

5. Before you install or remove any component, ensure that the

ATX power supply is switched off or the power cord is
detached from the power supply. Failure to do so may cause

severe damage to the motherboard, peripherals, and/or
components.

2.4 Central Processing Unit (CPU)

2.4.1 Overview

The motherboard comes with a surface mount 478-pin Zero Insertion
Force (ZIF) socket designed for the Intel® Pentium® 4 processor. The
processor includes the Intel® NetBurst™ micro-architecture that features
the hyper-pipelined technology, rapid execution engine, 400MHz system
bus, and execution trace cache. Together, these attributes improve system
performance by allowing higher core frequencies, faster execution of
integer instructions, and data transfer rate of up to 3.2GB/s.

Gold Mark

Note in the illustration that the CPU has a gold triangular mark on one
corner. This mark indicates the processor Pin 1 that should match a
specific corner of the CPU socket.

Incorrect installation of the CPU into the socket may bend the pins and
severely damage the CPU!
