Ethernet 10/100Base-T Straight Thru Cable

This cable will work with both 10Base-T and 100Base-TX and is used to connect a network interface card to a hub or network outlet. These cables are sometimes called "whips".

  4 Blue 4  
  5 White/Blue 5  
RX- 6 Green 6 RX-

Note: It's important that each pair is kept as a pair. TX+ & TX- must be in the pair, and RX+ & RX- must together in another pair. (Just as the table above shows).

Just for your information, this is how the pairs are named:

Pair Pins Common color
1 4 & 5 Blue
2 1 & 2 Orange
3 3 & 6 Green
4 7 & 8 Brown

The + side of each pair is called the "tip" and the - side is called the "ring", a reference to old telephone connectors.
