Step 2: Up and Running


Now that the SRX380 is powered on, let’s do some initial configuration to get the switch up and running on the network. It’s simple to provision and manage the SRX380 and other devices on your network. You can choose the configuration tool that’s right for you:

Configure Root Authentication

  1. Connect the management port (MGMT) on the SRX380 front panel to the Ethernet port on your laptop.

    The SRX380 functions as a DHCP server and automatically assigns an IP address to the laptop.

    Ensure that the laptop acquires an IP address on the network.

  2. If the laptop is unable to get an IP address, manually configure an IP address in the network.

    Be sure you don’t assign the IP address to the laptop because this is the IP address assigned to the SRX380.

  3. Set the root authentication password:
    1. Open a browser and type You don’t need to log in.

      The J-Web Setup wizard opens on your screen.

    2. Click Skip in the upper-right corner of the Setup wizard. The Device Password page appears.
    3. Type a root authentication password and click OK. The J-Web login page appears.

Plug and Play

The SRX380 already has factory-default settings configured right out of the box to make it a plug-and-play device. So all you have to do to get the SRX380 up and running is connect it to your LAN and WAN networks. Here’s how:

  1. Connect the WAN network to port 0/0.
  2. Connect the LAN network to any of the ports from 0/1 through 0/18.
  3. Check to see if the SRX380 is connected to the Internet. Go to If the page doesn’t load, check the Internet connection.

After you complete these steps, you can start using the SRX380 on your network right away. You can go back and customize settings at anytime. The J-Web Setup wizard is always available to you.

Customize the Basic Configuration

To customize basic settings using the J-Web Setup wizard, have these values handy:

  • Hostname

  • Root authentication password

  • IP address for the NTP server

  • IP address for the DNS server

  • IP address for the management interface

Log in to J-Web and select Configure > Setup Wizard to launch the Setup wizard. Select the configuration mode that’s right for you. You can then follow the screens as they appear in the Setup wizard.

  • Standard—Configure basic security settings for the SRX380.

  • Cluster (HA)—Set up the SRX380 in chassis cluster mode.

  • Passive—Set up the SRX380 in Tap mode. Tap mode enables the SRX380 to passively monitor traffic flows across a network.
