Cable pinouts

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.
Cable type
Based on performance
Ethernet cables can be classified as category 3, category 4, category 5, category 5e, category 6,
category 6A, and category 7 cables based on performance. Category 5, category 5e, and category 6
are the most commonly used twisted pair cables on LANs.

NOTE:
Connect 10-Gigabit RJ-45 ports on the switch by using category 6A or category 7 twisted pair
cables. Connect other RJ-45 ports on the switch by using category 5 or above twisted pair cables.
Based on pinouts
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
63.
•
Crossover—The pinouts at one end comply with standard 568B, and those at the other end
comply with standard 568A, as shown in
