Twisted-Pair Cabling
There are different grades, or categories, of twisted-pair cabling. Category 5
is the most reliable and is highly recommended. Category 3 is a good second
choice. Straight-through cables are used for connecting computers to a hub.
Crossover cables are used for connecting a hub to another hub (there is an
exception: some hubs have a built-in uplink port that is crossed internally,
which allows you to link or connect hubs together with a straight-through
cable instead).
You can buy pre-made Category 5
cabling, or cut and crimp your own.
Category 5 cables can be purchased or
crimped as either straight-through or
crossover. Inside a Category 5 cable are
8 thin, color-coded wires inside that run
from one end of the cable to the other.
All 8 wires are used. In a straight-
through cable, wires 1, 2, 3, and 6 at
one end of the cable are also wires 1, 2,
3, and 6 at the other end. In a crossover
cable, the order of the wires change
from one end to the other: wire 1
becomes 3, and 2 becomes 6. See the
diagrams on the next page for more
detailed information on
straight-through and
crossover cabling.
To determine which wire is wire number 1, hold the cable so that the end of
the plastic RJ-45 tip (the part that goes into a wall jack first) is facing away
from you. Face the clip down so that the copper side faces up (the springy
clip will now be parallel to the floor).When looking down on the copper side,
wire 1 will be on the far left.
7. After a few seconds you will be brought back to the main Network win-
dow. The TCP/IP Protocol should now be listed.

Supply them as needed (i.e.: D:\win98, D:\win95,
c:\windows\options\cabs.)
9. Windows will ask you to restart the PC. Click Ye s .
The TCP/IP Installation is complete.
