Network Port Connector Pinout Information for an EX3200 or EX4200 Switch

A network port on an EX3200 or EX4200 switch uses an RJ-45 connector to connect to a device.

The port uses an autosensing RJ-45 connector to support a 10/100/1000Base-T connection. Two LEDs on the port indicate link/activity on the port and the port status. See “Network Port LEDs in EX3200 and EX4200 Switches” on page 20.

Table 15 on page 40 provides the pinout information for the RJ-45 connector. An

RJ-45 cable, with a connector attached, is supplied with the switch.
