Network Port, QSFP+ Port, SFP Port, and SFP+ Port Connector Pinout Information for EX4300 Switches

Depending on the switch model EX4300 switches support 10/100/1000BASE-T Ethernet network ports, SFP network ports, SFP+ uplink and uplink module ports, and QSFP+ ports.

Tables in this topic describe the connector pinout information for these ports.

  • Table 44—10/100/1000BASE-T Ethernet network port connector pinout information
  • Table 45—SFP network port connector pinout information
  • Table 46—Built-in SFP+ port and SFP+ uplink module port connector pinout information
  • Table 47—Built-in QSFP+ port and QSFP+ uplink module port connector pinout information
