Chapter 2

This chapter lists the hardware setup procedures that you have to perform when installing or removing system components.

ASUS TW100-E5

Hardware setup

2.1 Chassis covers

2.1.1 Removing the left side cover

You have to remove the left side cover to install or replace internal components of

the server system.

• Ensure that you unplug the power cord before removing the side cover.

• Take extra care when removing the side cover. Keep your ngers from

components inside the chassis that can cause injury, such as the CPU fan, rear fan, and other sharp-edged parts.

To remove the left side cover

1. Remove the two screws that secure

the left side cover to the chassis.

2. Slide the left side cover for about

half an inch toward the rear until it is disengaged from the chassis.

3. Carefully lift the cover and set it

aside.

Chapter 2: Hardware setup2-2

2.1.2 Removing the right side cover

Most internal components can be installed or replaced after removing the left

side cover. However, for components such as Serial ATA hard disk drives, you

may have to remove the right side cover for easier component installation or replacement.

To remove the right side cover

1. Remove the two screws that secure the left side cover to the chassis.

2. Slide the right side cover for about

half an inch toward the rear until it is disengaged from the chassis.

3. Carefully lift the cover and set it aside.

2.2 Motherboard overview

The barebone server comes with the P5N-VM WS motherboard already installed. The motherboard is secured to the chassis by eight (8) screws as indicated by the

circles in the illustration below.

Refer to Chapter 3: Motherboard information for detailed information on the motherboard.

Place this side towards the rear of the chassis

Ensure to unplug the power cord before installing or removing any motherboard component or connection. Failure to do so can cause you physical injury and damage motherboard components.

Chapter 2: Hardware setup2-4

2.3 Central Processing Unit (CPU)

The motherboard comes with a surface mount LGA775 socket designed for the

Intel® Core™ 2 Extreme / Core™ 2 Quad / Core™ 2 Duo / Pentium Celeron® dual-core / Celeron® processors.

2.3.1 Installing the CPU

To install a CPU:

1. Locate the CPU socket on the motherboard.

Before installing the CPU, make sure that the socket box is facing towards you

and the load lever is on your left.

dual-core /

2. Press the load lever with your

thumb (A), then move it to the left

(B) until it is released from the

retention tab.

To prevent damage to the socket pins, do not remove the PnP cap unless you are installing a CPU.

3. Lift the load lever in the direction of

the arrow to a 135º angle.

4. Lift the load plate with your thumb

and forenger to a 100º angle (4A),

then push the PnP cap from the

load plate window to remove (4B).

5. Position the CPU over the socket,

making sure that the gold triangle is on the bottom-left corner of the

socket then t the socket alignment

key into the CPU notch.

The CPU ts in only one correct

orientation. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU!

6. Apply several drops of thermal paste

to the exposed area of the CPU that the heatsink will be in contact with, ensuring that it is spread in an even thin layer.

Some heatsinks come with preapplied thermal paste. If so, skip this step.

The Thermal Interface Material is toxic and inedible. If it gets into your eyes or touches your skin, ensure to wash it off immediately, and seek professional medical help.

To prevent contaminating the paste, DO NOT spread the paste with your nger

directly.

Chapter 2: Hardware setup2-6

7. Close the load plate (A), then push

the load lever (B) until it snaps into

the retention tab.

2.3.2 Installing the CPU heatsink

The IntelIntel® Core™ 2 Extreme / Core™ 2 Quad / Core™ 2 Duo / Pentium core / Celeron® dual-core / Celeron® processors require an Intel certied or ASUS

qualied heatsink and fan assembly to ensure optimum thermal condition and

performance.

When you buy a boxed Intel CPU, the package includes the cooler, fan, thermal

grease, installation manual, and other items that are necessary for CPU installation.

• Ensure that you have applied the thermal grease to the top of the CPU before installing the heatsink and fan.

• Refer to the installation manual that came with the CPU package for details on heatsink/fan assmbly and installation.

To install the CPU cooler and fan

1. Place the cooler on top of the installed CPU, making sure that the four screws match the holes on the support plate.

The support plate only comes with the optional CPU heatsink. If you buy a boxed Intel CPU with a bundled CPU fan, you can install the CPU fan without the support plate.

2. Use a screwdriver to tighten the

four (4) cooler screws in a diagonal sequence.

Chapter 2: Hardware setup2-8

3. Connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN.

Do not forget to connect the CPU_FAN connector! Hardware monitoring errors can occur if you fail to plug this connector.

2.4 System memory

2.4.1 Overview

The motherboard comes with four Double Data Rate II (DDR2) Dual Inline Memory Modules (DIMM) sockets to support 240-pin DDR2 modules.

2.4.2 Memorycongurations

You may install 512 MB, 1 GB, and 2 GB non-ECC, unbuffered DDR2 DIMMs into

the DIMM sockets.

• You may install varying memory sizes in Channel A and Channel B. The system maps the total size of the lower-sized channel for the dual-channel conguration. Any excess memory from the higher-sized channel is then

mapped for single-channel operation.

• Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor.

• When installing total memory of 4GB capacity or more, Windows 32bit operation system may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is recommended.

• This motherboard does not support memory modules made up of 128 Mb

chips.

• Due to chipset limitation, this motherboard can only support up to
