Connecting and Communicating with the Router

	Command or Action	Purpose
Step 3
	Start the terminal emulation program.	(Optional) Prepares a computer for router communications.
		• The step is not required if you are connecting through a
		terminal.
		• Terminals send keystrokes to and receive characters
		from another device. If you connect a computer to the
		Console port, you must use a terminal emulation
		program to communicate with the router. For
		instructions on using the terminal emulation program,
		see the documentation for that program.
Step 4
	Press Enter.	Initiates communication with the router.
		• If no text or router prompt appears when you connect to
		the Console port, press Enter to initiate
		communications.
		• If no text appears when you press Enter and the router
		has been started recently, give the router more time to
		complete the initial boot procedure, then press Enter.
		• If the router has no configuration, the router displays
		the prompt: Enter root-system username:. If a
		standalone router is starting up for the first time, see
		Chapter 2, “Bringing Up the Cisco IOS XR Software on
		a Standalone Router.” If a multishelf system is starting
		up for the first time, see Chapter 3, “Bringing Up the
		Cisco IOS XR Software on a Multishelf System.”
		• If the router has been configured, the router displays the
		prompt: Username:
Step 5
	Log in to the router.	Establishes your access rights for the router management
		session.
		• Enter your username and password, as described in the
		“Logging In to a Router or an SDR” section on
		page 4-11.
		• After you log in, the router displays the CLI prompt,
		which is described in the “CLI Prompt” section on
		page 4-12.

Establishing a Connection Through a Terminal Server

A terminal server connection provides a way to access the Console port from a remote location. It is less expensive to connect to the router through the Management Ethernet interface (because you do not have the additional cost of a terminal server). However, if you need to perform tasks that require Console port access from a remote location, a terminal server is the best connection method.

The procedure for connecting to the router through a terminal server is similar to the procedure for directly connecting through the Console port. For both connection types, the physical connection takes place through the Console port. The difference is that the terminal server connects directly to the Console port, and you must use a Telnet session to establish communications through the terminal server to the router.
