In this guide, we provide a simple, three-step path, to quickly get you up and running with your new SRX320. We’ve
simplified and shortened the installation and configuration steps, and included how-to videos. You'll learn how to install
the SRX320 in a rack, power it up, and deploy it on your network using the CLI.
NOTE: We think you'll want to check out our Guided Setup: SRX300 Line Firewalls. Our Guided Setup picks
up where this Day One+ ends, providing step-by-step instructions on how to easily secure and validate your
branch location.

Meet the SRX320
The Juniper Networks®SRX320 Firewall provides next-generation security, routing, switching, and WAN connectivity in
a small desktop device. The SRX320 features eight 1GbE ports, including six RJ-45 network ports and two small form-factor
pluggable (SFP) transceiver ports. The SFP ports are MACsec capable.

You can install the SRX320 on a table or desk, on a wall, or in a rack. We show you how to install it in a rack.
What’s in the Box?
•SRX320 Firewall
•A power cord appropriate for your geographic location
•A USB cable
What Else Do I Need?
DB-9 to RJ-45 cable or a DB-9 to RJ-45 adapter with a CAT5E copper cable—We no longer include a DB-9 to RJ-45 cable
or a DB-9 to RJ-45 adapter with a CAT5E copper cable as part of the device package. If you require a console cable, you
can order it separately with the part number JNP-CBL-RJ45-DB9 (DB-9 to RJ-45 adapter with a CAT5E copper cable).

To mount the SRX320 in a rack, you’ll need to order the rack mount kit appropriate for your installation. The required
rack mount kit depends on whether you have a PoE or non-PoE SRX320 model, and whether you already have a power
supply adapter tray. Check out the following table to see which rack mount kit you need.

Rack It
1. Review General Safety Guidelines and Warnings.
2. Wrap and fasten one end of the electrostatic discharge (ESD) grounding strap around your bare wrist, and connect the
other end to a site ESD point.
3. Attach the mounting bracket and power supply adapter tray to the sides of the SRX320 using the screws that came
with the rack mount kit and the screwdriver.
3
4. Place the power supply adapter in the tray.
5. Lift the SRX320 and position it in the rack. Line up the bottom hole in the mounting brackets with a hole in each rack
rail, making sure the SRX320 is level.
4
6. While you’re holding the SRX320 in place, have a second person insert and tighten the rack mount screws to secure
the adapter tray and mounting brackets to the mounting rails. Make sure to tighten the screws in the two bottom holes
first and then tighten the screws in the two top holes.

7. Check that the mounting brackets on each side of the rack are level.
Power On
Now that you’ve installed the SRX320 in the rack, you’re ready to connect it to power.
5
1. Wrap and fasten one end of the electrostatic discharge (ESD) grounding strap around your bare wrist, and connect the
other end to a site ESD point.
NOTE: If the SRX320 has a supply adapter tray, you can perform step 2 and 3 with the power supply adapter
seated in the tray.
2. Plug the DC connector end of the power cable into the power connector at the back of the SRX320.

3. Plug the AC adapter end of the power cable into the power supply adapter.
4. If the AC power source outlet has a power switch, turn it off.
5. Plug the power cord into the AC power source outlet.
6. If the AC power source outlet has a power switch, turn it on.
The SRX320 powers up as soon as you connect it to power. When the STAT LED on the front panel is lit solid green,
the SRX320 is ready to use.
Step 2: Up and Running

Initial Configuration Using the CLI | 7
Now that the SRX320 is powered on, let’s do some initial configuration to get it up and running on the network.

NOTE: Be sure to check out our Guided Setup: SRX300 Line Firewalls. Our Guided Setup picks up where this
Day One+ leaves off, providing step-by-step instructions on how to easily secure and validate your branch
location.
SRX320 Provisioning Options
It’s simple to provision and manage the SRX320 and other devices on your network. Choose the configuration tool that’s
right for you:
•Junos CLI commands. In this guide we show you how to configure the SRX320 with CLI commands that leverage the
plug and play factory defaults.
•J-Web, Juniper Networks GUI is pre-installed on the SRX320. For information on performing initial configuration using
the J-Web setup wizard see Configure SRX Devices Using the J-Web Setup Wizard in the J-Web User Guide for SRX
Series Devices.
•Juniper Networks Cloud-based applications. These applications feature plug and play to quickly get you up and running
on the network:
•Juniper Sky™ Enterprise, Juniper Networks-hosted public cloud-based Software as a Service (SaaS) solution. You’ll
need to have a Juniper Sky Enterprise subscription service before you can use it to configure the SRX320. For more
information, check out the Juniper Sky Enterprise Getting Started Guide.
•Contrail Service Orchestration (CSO). If you're using Junos OS Release 19.2 or earlier, you can use Juniper Networks
Network Service Controller to configure the SRX320 with ZTP. Network Service Controller is a component of CSO.
See Configure the Device Using ZTP with Juniper Networks Network Service Controller.
To use CSO, you’ll need an authentication code. See the Contrail Service Orchestration (CSO ) Deployment Guide.
Initial Configuration Using the CLI
IN THIS SECTION
Connect to the Serial Console Port | 8
Perform Initial Configuration | 9
Congratulations! Your SRX is Up and Running | 11
7
You can use the console port on the SRX to do the initial configuration. This section assumes you start from a factory
default configuration. See SRX320 Firewall Hardware Guide for details on the SRX320 factory default configuration.
After you configure the SRX320, you can log in on a local LAN port, or remotely over the WAN interface, to manage and
configure the SRX using the CLI or J-Web.
We recommend that you use the ge-0/0/0 interface for WAN connectivity on the SRX320. By default this interface is
set to receive its Internet access configuration from the service provider.
NOTE: This examples assumes you are using DHCP to configure the WAN interface. If the WAN provider does
not support DHCP ypu’ll need to manually configure the WAN interface and related static routing. See Junos
Initial Configuration.
Have this information handy before you begin the initial configuration:
•Root password
•Hostname
Connect to the Serial Console Port
1. Plug one end of the Ethernet cable into the RJ-45 to DB-9 serial port adapter for your SRX320.
NOTE: We no longer include a DB-9 to RJ-45 cable or a DB-9 to RJ-45 adapter with a CAT5E copper cable
as part of the device package. If you require a console cable, you can order it separately with the part number
JNP-CBL-RJ45-DB9 (DB-9 to RJ-45 adapter with a CAT5E copper cable).
2. Plug the RJ-45 to DB-9 serial port adapter into the serial port on the management device.
3. Connect the other end of the Ethernet cable to the serial console port on the SRX320.
8
4. Start your asynchronous terminal emulation application (such as Microsoft Windows HyperTerminal) and select the
appropriate COM port to use (for example, COM1).
5. Verify that the serial port settings are set to the default:
•Baud rate—9600
•Parity—N
•Data bits—8
•Stop bits—1
•Flow control—none
NOTE: You can also connect to the SRX320 using a mini-USB console port. See the SRX320 Hardware Guide.
Perform Initial Configuration
1. Login as the root user and start the CLI. You don't need a password if you're running the factory default.
login: root
root@%cli
root>
NOTE: You can view the factory-default settings with the show configuration operational mode command.
2. Enter configuration mode.
root> configure
[edit]
root#
3. Since you're doing the initial configuration manually, you'll need to remove ZTP from the configuration. This stops the
periodic log messages that report on ZTP status.
Set the root authentication password and commit the change to deactivate ZTP.
[edit]
root# delete chassis auto-image-upgrade
root# delete system phone-home
root# set system root-authentication plain-text-password
New password: password
9
Retype new password: password
Issue the commit command to activate the candidate configuration that disables ZTP:
[edit]
root# commit
4. Enable root login over SSH, and allow SSH access over the WAN interface (ge-0/0/0).
[edit]
root# set system services ssh root-login allow
root# set security zones security-zone untrust interfaces ge-0/0/0.0 host-inbound-traffic system-services ssh
5. Configure the hostname.
[edit]
root# set system host-name host_name
6. That’s it! The initial configuration is complete. Commit the configuration to activate the changes on the SRX.
[edit]
root# commit
