122RJ-45 connectorAn Ethernet twisted pair cable connects network devices through the RJ-45 connectors at the twoends. Figure 67 shows the pinouts of an RJ-45 connector.Figure 67 RJ-45 connector pinout diagramCable pinoutsEIA/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: brownsolid.• 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: brownsolid.Cable typeBased on performanceEthernet cables can be classified into category 3, category 4, category 5, category 5e, category 6,category 6A, and category 7 cable based on performance.Table 69 Ethernet cable descriptionType DescriptionCategory 5 Transmits data at a maximum speed of 100 Mbps, with a bandwidth of 100 MHz.Category 5e Transmits data at a maximum speed of 1000 Mbps, with a bandwidth of 100 MHz.Category 6 Transmits data at a speed higher than 1 Gbps, with a bandwidth of 250 MHz.Category 6A Transmits data at a speed higher than 10 Gbps, with a bandwidth of 500 MHz.Category 7 Transmits data at a speed higher than 10 Gbps, with a bandwidth of 600 MHz.NOTE:• Connect 10-Gigabit RJ-45 ports on the S12500-X switch by using category 6A or category 7 twistedpair cables.• Connect other RJ-45 ports on the S12500-X switch by using category 5 or above twisted pair cables.PIN #8PIN #1
