1. Setting the Cabinet ready: -

         Check how to open the cabinet and determine where to fix the components.

2. Fitting the Mother board.

        Open the cabinet on either side

b) The back side of the

Check whether the mother board is placed in such a way that the I/O ports of the motherboardcorrectly

fit in the I/O shields. Ensure all the specified screws for the motherboard are fixed and intact.

3.Installing the CPU:

    CPU is one of the most dedicated components of the computer.

    The CPU pins have to be clearly studied before fixing into the relevant processor space on

the motherboard.

. 

After the CPU is rightly placed in its position the lever is to be locked.

As a part of the CPU installation, before the CPU is fixed in the right

position a lever is provided, which needs to be unlocked. This lever is

perpendicular to the mother board.The CPU, which is a square shaped electronic component, comes with pins below it.

One should find for an indication on one of the corners of the CPU on both sides.

This arrow mark is also found on the motherboard which guides for the fixation of the

CPU. Once match of the pins verses motherboard slot gently push the CPU.

After the CPU is rightly placed in its position, the lever is to be locked.

Installing CPU fan

The CPU heat sink fan is to be carefully plugged on to the CPU by pushing down

the metal plastic clips.

The metal/plastic clips provided with heat sink fan should fix on to the CPU

socket and have to be locked. c)Once the heat sink CPU fan is fixed and locked,

it should be connected to the power supply available on the mother board through

the power connector.

4.Fitting the RAM:

    RAM Installation:

Next is installing the RAM. Insert the RAM into an available expansion socket.

Note how the RAM is keyed to the socket. This ensures the RAM can be plugged

into the socket one way only. Finally press the RAM firmly into position,

making certain the Ram is completely seated in the socket.

.

5.Installing SMPS:

    Next is installing the SMPS. This is an electronic power supply unit that provides and regulates     the power supply to all components of a computer system.

    As shown in the diagram the SMPS needs to install into cabinet at the place provided for it. 

    After placing the SMPS into the relevant provider space fix the outer screws to it intact.

6.Installing the ATX Power Connector ATX Connectors
Next installing the ATX power connector. It is a 20/24-pin power connector. This is the primary power

supply to the mother board.

7.Installing the HDD and Floppy disk:

Installing the Hard Disk Drive (HDD) is clearly understood in the following steps.

First see the rare of the HDD. It consists of the 3 types of pins.

One left side the HDD has multiple pins termed as the IDE connector.

In the middle is the jumper setting pins for the HDD.

On the extreme right side is the power connector pins

. Every device except FDD (floppy Disk Drive)

uses this type of power connector. And HDD and CDD (Compact Disk Drive)

connected by this type of IDE cable.

Power connector

Mount the HDD into mounting slot meant for the HDD with the rear end facing and

secure the inner screws intact.

Connect the IDE cable to the HDD as well as the mother board as shown in the figure.

Remember for all the power connectors to be plugged in, one needs to align the Red line on

the cable to Pin-1 of the IDE port. Hence connect the power cable to the HDD rare end

by gently pushing theconnector.

8.Floppy Disk Drive installation: Installation of FDD is very similar to HDD.

We need to identify the relevant pins for the mother board and power supply connectivity.

First step in the FDD installation is mounting of the FDD into the FDD mounting slot by removing

the cover side of front side of the cabinet as shown in the figure below.

-Push the FDD case into opened of the cabinet curtaining of the FDD.

-Secure FDD with inner screws.

Connect the one end of cable to mother board and other to end to FDD

Connect the power connector to the FDD.

9.CD ROM Installation:
Next installing the CD-ROM. Remove the cover of front side of the cabinet curtaining

of the CD-ROM.

Push CD-ROM case into opened space. Secure CD-ROM with inner screws.

Connect the one end of cable to motherboard and another end to CD-ROM.

Connect the power connector to the CD-ROM.

10.Switches and LED connectors:

    Installing the Switches and LEDs of front side of the cabinet.

Please refer to your mother board manual to locate where the connectors are.

Different mother boards place the connectors in different locations. The connectors

for the switches and LEDs are normally grouped together. They should look similar to

the figure given below.

11.Input/Output Device Installation: Finally connect all peripheral devices like mouse,

key- board, monitor, etc, to the I/O ports shown in the figure below.

Keyboard:

Keyboard has round shape connectors. The male connector appears at the edge

of the keyboard’s cable and the female connector appears at the back side of the system unit.

We are using the 6 pins round keyboard connector.

Mouse:

The mouse connector is same as the keyboard connector. The male connector appears

at the edgeof mouse cable and female connector appears at the backside of the system.

It is also having 6 pins toconnect the mouse.

Monitor:

The monitor of computer has „D‟ shape connectors. The male

Monitor connector has 15 pins and it appears at the edge of monitor‟s cable.

The female monitor connector appears at the back of the system unit.

Printer:

Printer connector is the oldest connector of a computer. The male printer connector has 25

pins and itappears at the edge of the printer cable and the backside of the system unit

Audio/Speakers:

For audio effect we are using speakers. The audio male connector have single thick pin

and each male connector of individual speaker is distinguish with separate colour.

The male connectors

appear at the edge of the speaker cables. The female audio connectors appear in

same colour at the back side of the system. The female audio connectors have some

special symbols i.e,

The first symbol displays “line-out”.
The second symbol displays “line-in”.
The third symbol displays “Mic-in”.

Line-out it sends the out put to speakers.

Line-in it takes the input from speakers.

Mic-in it takes the input from microphone

Ethernet / Networking:

The Ethernet connectors are used when two or more than two computers

need to linked with otherover a computer network like LAN (local area network).

The of male Ethernet connector is quite similar to male modem connector except

it is more flat.The female Ethernet connector appears at the backof the system unit.

USB:

USB (universal serial bus) is the latest and most popular connector.

Using USB connectors we can connect so many different devices

our computer. Any device equipped with has slim male connectorwith

slim metal coating appearing at the end of the devices cable. For connecting

the device, a female USB connector is provided at the back of the system unit.

We can identify the USB connector with this symbol.
