Four built-in Gigabit Ethernet ports provide LAN connections over copper interfaces to hubs, switches, local servers, and workstations. You can also designate an Ethernet port for management traffic. When configuring one of these ports, you use the interface name that corresponds to the port’s location. From left to right on the front panel, the interface names for the ports are ge-0/0/0, ge-0/0/1, ge-0/0/2, and ge-0/0/3.
For Gigabit Ethernet port pinout information, see RJ-45 Connector Pinout for Gigabit Ethernet Ports.
Each port has two LEDs, a TX/RX LED on the left side and a LINK LED on the right side. Table 10 describes the built-in Ethernet port LEDs.
