Step 2: Up and Running

Connect and Configure

You’ll need to do the initial configuration of the NFX250 through the console port using the CLI. Before you begin connecting and configuring the NFX250, make sure the serial port on your laptop or PC are set to the defaults:

• Baud Rate—9600

• Flow Control—None

• Data—8

• Parity—None

• Stop Bits—1

• DCD State—Disregard

Here’s how to connect and configure the NFX250 to the network from the console port:

1. Connect the console port (labeled CON on the NFX250 front panel) to a laptop using the RJ-45 cable and RJ-45 to DB-9 adapter (not provided). The Juniper Device Manager (JDM) CLI is displayed.
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.
3. Start the CLI.
4. Enter configuration mode.
5. Add a password to the root administration user account. Enter a plain text 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.
   Note

   jmgmt0 is the out-of-band management network interface in JDM.

   
   
   

   To configure an IPV6 address, type root@jdm# set interface jmgmt0 family inet6 address address v6_address.

   Note

   jmgmt0 is the management port labeled MGMT on the NFX250 front panel.

8. Configure the default gateway.
9. Commit the configuration to activate it on the device.
10. Connect the NFX250 to the Internet (WAN ports 0/12 and 0/13).

    The ISP assigns an IP address to the NFX250 through Dynamic Host Configuration Protocol (DHCP).

11. Connect your laptop to a LAN port (ports 0/0 to 0/11).

    The DHCP server running on the NFX250 assigns an IP address to your computer.
