You configure the switch by issuing Junos OS command-line interface (CLI) commands, either on a console
device attached to the console (CON) port on the front panel, or over a telnet connection to a network
connected to the Ethernet management (C0 or C1) port on the front panel.
Before you begin connecting and configuring an EX4650 switch, gather the following information:
Name the switch will use on the network
Domain name the switch will use
IP address and prefix length information for the Ethernet interface
IP address of a default switch
IP address of a DNS server
Password for the root user
This procedure connects the switch to the network, but does not enable it to forward traffic. For complete
information about enabling the switch to forward traffic, including examples, see the Junos OS configuration
guides.
To configure the software:
1. Verify that the switch is powered on.
2. Log in as the root user. There is no password.
3. Start the CLI.
root# cli
root@>
4. Enter configuration mode.
cli> configure
[edit]
root@#
5. Set the root authentication password by entering either a clear-text password, an encrypted password,
or an SSH public key string (DSA or RSA).
[edit]
root@# set system root-authentication plain-text-password
New password: password
Retype new password: password
