UTP cable is the most common cable in LANs.


Lab Length:
1 Hour


Lab

In this lab you will make a UTP network cable, and a UTP crossover network
cable, and then use the crossover cable to connect two PCs toge
ther to
transmit and receive data over a small peer
-
to
-
peer network.


1.

Cut the appropriate length cable with wire cutters.




2.

On one end of the cable, strip approximately three quarters of an inch
off of the outer jacket exposing the eight colored wires.




3.

To make a regular UTP cable, arrange the wires in the following order
from left to right:

4.

Trim the ends of the wires to an even length with wire cutters.




5.

Slide the wires in
to the RJ
-
45 connector with the copper tabs facing up
(hook is facing down), and the wires in the order listed above. Make sure
all the wires seat all the way forward in the connector.




6.

Crimp tightly using the crimping tool.




7.

Follow steps 2
-
6 again o
n the other side of the cable.


8.

Test cable with cable tester.





9.

Now make a UTP crossover cable. To make a crossover cable follow the
same procedure on one end, and on the other end follow the same
procedure with the following wire order from left to rig

10.

Test crossover cable with cable tester.


11.

Take two PCs and connect them from NIC card to NIC card with the UTP
crossover cable.




12.

On both computers enter the DOS Command Prompt
by clicking on
“Start”, “Programs”, “Accessories”, “Command Prompt.”


13.

Type “ipconfig” and press “Enter” to find the IP Address of both
computers.




In this case the IP Address is “12.253.8.111”. If no IP Address appears or if
it appears as all 0’s, go to

step 15 to load the TCP/IP Protocol.


14.

To verify that the computers are indeed connected we will have them
‘ping’ eachother. Type “ping 12.253.8.111” (replace my IP Address with
your IP Address) and then press “Enter”. Do this to both computers, but
do not

type the IP Address of the computer that you are currently on,
rather type the IP Address of the other computer. It’s like calling
someone. The IP Address is like the telephone number of the computer,
so if I want to call you I have to dial your number, n
ot my own. You should
see something similar to this:




Notice that the host computer’s IP Address is still posted on top,
“12.253.8.111”, but I ‘pinged’ the other computer’s IP Address which was
“12.253.8.120” and got a response. Do this with both comput
ers. If it works
then proceed to step 29.


15.

THE FOLLOWING STEPS ARE ONLY TO BE DONE IF NO IP ADDRESS
IS FOUND IN STEP 13. To load the TCP/IP Protocol right
-
click on the
“My Network Places” icon on the desktop and select “properties” from
the pull
-
down menu
that appears. This opens the “Network and Dial
-
up
Connections” Properties window. It should look something like this:




16.

Right
-
click on the “Local Area Connection” icon and select “Properties”
from the pull
-
down menu that appears. The “Local Area Connecti
ons
Properties” box will appear and should look something like this:




17.

Click the “Install” button. The “Select Network Component Type” box will
appear and look like this:




18.

Select “Protocol” from the list and click “Add”. The “Select Network
Protocol”
box will appear and look like this:




19.

Select “Internet Protocol (TCP/IP)” from the list and click “Ok”. This will
install the TCP/IP Protocol. You also want to make sure you have a “Client
for Microsoft Networks” and “File and Printer Sharing for Microso
ft
Networks”. If you already have BOTH of these items and your screen
looks similar to the picture below then you may proceed to step 26. If
not then click on “Install” again and go to the next step to install the
client and service.




20.

The “Select Networ
k Component Type” box will appear again and look like
this:




21.

Select “Client” from the list and click the “Add” button. The “Select
Network Client” box will appear:




22.

Select “Client for Microsoft Networks” from the list and click “OK”. This
will take y
ou back to the screen depicted in step 19. If you still do not
have all three items proceed to the next step, otherwise skip to step 26.


23.

Click on “Install” one more time. The “Select Network Component Type”
box will appear again and look like this:




24.

Se
lect “Service” from the list and click “Add”. The “Select Network
Service” box will appear:




25.

Select “File and Printer Sharing for Microsoft Networks” from the list
and click “OK”. This will take you back to the screen depicted in step 19.
You should hav
e all the items on that list now, and can proceed to the
next step.


26.

Now that all the items you need for networking are installed you have to
establish an IP Address. Select “Internet Protocol (TCP/IP)” and click
the “Properties” button. The “Internet Prot
ocol TCP/IP Properties” box
will appear:




27.

Click the radio button next to “Use the following IP address:”. Fill the
boxes below to look like this:




For each computer make the last digit in the “IP address” row different
(example: 10.0.0.2), but make
sure the number in the “Subnet mask” row is
the same for all computers on your network. When you are done click on
“OK”.


28.

Now you have established an IP address and all of the items needed for
networking. Click “Close” and then go back to the beginning of

step 12.


29.

Now we will use another method to see what computers are on the
network. Close all open windows. Double
-
click on the “My Network Places”
icon on the desktop and something similar to this should appear:




30.

Double
-
click on the “Entire Network” ic
on and this should appear:




31.

Click on the “entire contents” blue link. Something similar to this will
appear:




32.

Double
-
click on the “Microsoft Windows Network” icon and a list of all
the workgroups in your network will appear. It will look similar to t
his:




33.

Double
-
click on the workgroup you wish to view and you will see a list of
all the computers’ network names that are actively in that workgroup. If
you wish to view shared information on a specific computer all you have to
do is double
-
click on it
from this screen and use it like it were on your
local computer if you have the appropriate network security clearence.


34.

Now that we have verified the connection, we will use the connection to
map a network drive, but before that can be done we must share

a drive
to be mapped to. Do the following steps on both computers. Close all open
windows. Double
-
click on the “My Computer” icon on the desktop. This will
bring up a screen that shows all of the disk drives on your computer, like
this:




35.

Right
-
click on

the “Local Disk (C:)” icon and select “Properties” from the
pull
-
down menu. This displays the hard disk’s properties window that
provides information about the local hard disk:




36.

Click on the “Sharing” tab towards the top of the window. This will displa
y
something like the picture below:




37.

Select “Share this folder”. In the text box next to “Share name” type
“C”:




38.

Click “OK”. The hard disk on that computer is now shared. Remember to
do this to both computers.


39.

Once both computers have their hard di
sks shared close all open windows.
Right
-
click on either the “My Computer” or “My Network Places” icon and
select “Map network drive” from the pull
-
down menu that appears. The
screen that appears will look like this:




40.

Make sure the box next to “Reconnec
t at logon” in not checked. In the
box next to “Folder:” type two backslashes followed by the network name
of the computer you want to map to followed by one backslash and the
share name on that computer that you want to map to. Look at the
example below.
When the information is correct click “Finish”.


A new window will appear. This window contains the contents of the drive you
just mapped, in this case the other computer’s hard disk. Depending on the
network and share permissions you can use this window j
ust like it was a
second hard disk on the compter you are on. You can get information from it
and you can send information to it. It functions like a part of your computer,
even though it is still physically in the other computer. Sharing is not limited
to

entire disk drives. You can choose to share a single folder if you want, and
the procedure is the same for sharing it and mapping to it.


41.

To disconnect from the mapping close the window viewing that mapping.
Right
-
click on either the “My Computer” or “My

Network Places” icon and
select “Disconnect network drive” from the pull
-
down menu that appears.
This will display a window similar to this:


42.

Select the network drive you wish to disconnect and click “OK”.


Conclusion

In this lab you learned how to make U
TP and UTP crossover cables and
connect two PCs using the crossover cable. You also learned how to verify
that two computers are able to transmit and receive data to and from
eachother.
