M10i Routing Engine Interface Ports

Each Routing Engine has a set of ports for connecting to one or more external devices on which system administrators can issue Junos OS command-line interface (CLI) commands to manage the router (see M10i Routing Engine 850 LEDs).

The ports with the indicated label in each set function as follows:

• AUX/MODEM— Connects the Routing Engine to a laptop, modem, or other auxiliary device through an RS-232 (EIA-232) serial cable.
• MGMT—Connects the Routing Engine through an Ethernet connection to a management LAN (or any other device that plugs into an Ethernet connection) for out-of-band management. The port uses an autosensing RJ-45 connector to support both 10- and 100-Mbps connections.

  To the left of each MGMT port is a link status indicator, which lights to show that a link has been established over the Ethernet connection. To the right of each MGMT port is an activity indicator, which flashes when data is being transferred.

• CONSOLE—Connects the Routing Engine to a system console through an RS-232 (EIA-232) serial cable.
