Built-In Gigabit Ethernet Ports

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-0/0/3
For Gigabit Ethernet port pinout information, see "Gigabit Ethernet uPIM RJ-45
Connector Pinout" on page 235.
Each port has two LEDs, a
side. Table 10 on page 23 describes the built-in Ethernet port LEDs.

Console Port

You can use the console port on the chassis front panel to connect to the Routing
Engine through an RJ-45 serial cable. From the chassis console port, you can use the
CLI to configure the router. The console port is configured as data terminal equipment
(DTE) and supports the RS-232 (EIA-232) standard.
For information about securing the chassis console port, see the J-series Services
Router Administration Guide.
For pinout information, see "Chassis Console Port Pinouts" on page 236.
