2. Log in as root. There is no password. If the software booted before you connected the cable to the console port, you
might need to press the Enter key for the prompt to appear.

New password: password
Retype new password: password
6. (Optional) Give the NFX250 a name. If the name includes spaces, enclose the name in quotation marks (“ ”).

7. Configure the IP address and prefix length for the device management interface.
[edit]
root@jdm# set interfaces jmgmt0 unit 0 family inet address address/prefix-length
