NOTE:
The RJ-45 Ethernet interfaces use category 5 or higher Ethernet twisted pair cables for connection.
EIA/TIA cabling specifications define two standards, 568A and 568B, for cable pinouts.
•
Standard 568A—pin 1: white/green stripe, pin 2: green solid, pin 3: white/orange stripe, pin 4:
blue solid, pin 5: white/blue stripe, pin 6: orange solid, pin 7: white/brown stripe, pin 8: brown
solid.
•
Standard 568B—pin 1: white/orange stripe, pin 2: orange solid, pin 3: white/green stripe, pin 4:
blue solid, pin 5: white/blue stripe, pin 6: green solid, pin 7: white/brown stripe, pin 8: brown
solid.
Ethernet twisted pair cables can be classified into straight through and crossover cables based on their
pinouts:
•
Straight-through—The pinouts at both ends comply with standard 568B, as shown in
.
•
Crossover—The pinouts at one end comply with standard 568B, and those at the other end
comply with standard 568A, as shown in
