Figure 60 RJ-45 connector pinout
NOTE:
The RJ-45 Ethernet ports of the HP A-F5000 firewall 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 are T568B compliant, as shown in
Crossover: The pinouts are T568B compliant at one end and T568A compliant at the other end, as
•
shown in Figure 62.
