Figure 49 RJ-45 connector pinout diagram

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 Figure 50.

• C

rossover—The pinouts at one end comply with standard 568B, and those at the other end

comply with standard 568A, as shown in Figure 51.
