You’ll also need:

Someone to help you do the installation
Rack mount screws appropriate for your rack
A number two Phillips (+) screwdriver
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).

Rack It

Here’s how to install the SRX345 in a rack:

Review General Safety Guidelines and Warnings.
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.
Attach the mounting brackets to the sides of the SRX345 using the eight mounting screws and the screwdriver. Depending on how you’d like he SRX345 to sit in the rack, you can attach the mounting brackets to the front or center mounting holes.
Lift the SRX345 and position it in the rack. Line up the bottom hole in each mounting bracket with a hole in each rack rail, making sure that the SRX345 is level.
While you’re holding the SRX345 in place, have a second person insert and tighten the rack mount screws to secure the mounting brackets to the rack. Make sure to tighten the screws in the two bottom holes first and then tighten the screws in the two top holes.
Check that the mounting brackets on each side of the rack are level

Power On
Now that you’ve installed your SRX345 in the rack, you’re ready to connect it to power

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the other end of the ESD strap to the ESD point on the rack.
Attach a grounding cable to earth ground, and then attach the other end to the grounding point on the side panel of the SRX345.
Plug the power cord into the SRX345 rear panel.
If the AC power source outlet has a power switch, turn it off.
Plug the other end of the power cord into the AC power source outlet.
If the AC power source outlet has a power switch, turn it on.
If you are using a SRX345 Firewall with dual AC power supplies, then repeat Step 3 through Step 5 for the second power supply. The SRX345 powers up as soon as you connect it to power. When the PWR and STAT LEDs on the front panel are lit solid green, the SRX345 is ready to use.

Step 2: Up and Running

Initial Configuration Using the CLI | 6

Now that the SRX345 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.

SRX345 Provisioning Options
It’s simple to provision and manage the SRX345 and other devices on your network. You can choose the configuration tool that’s right for you:

Junes CLI commands. In this guide we show you how to configure the SRX345 with CLI commands that leverage the plug and play factory defaults.
J-Web, Juniper Networks Setup wizard that is preinstalled on the SRX345. 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 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 SRX345. For more information, check out the Juniper Sky Enterprise Getting Started Guide.
Juniper Networks Contrail Service Orchestration (CSO). To use CSO, you’ll need an authentication code. See the Contrail Service Orchestration (CSO ) Deployment Guide

If you are using Junos OS Release 19.2 or earlier, you can use Juniper Networks Network Service Controller to configure the SRX345 with ZTP. Network Service Controller is a component of CSO. See Configure the Device Using ZTP with Juniper Networks Network Service Controller.

Initial Configuration Using the CL

N THIS SECTION
Connect to the Serial Console Port | 7
Perform Initial Configuration | 8
Congratulations! Your SRX is Up and Running | 9

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 SRX345 Firewall Hardware Guide for details on the SRX345 factory default configuration.

After you configure the SRX345, 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 SRX345. 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, you’ll need to manually configure the WAN interface and related static routing. See Junes Initial Configuration.

Have this information handy before you begin the initial configuration:

Root password
Hostname

Connect to the Serial Console Port

Plug one end of the Ethernet cable into the RJ-45 to DB-9 serial port adapter for your SRX345
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)
Plug the RJ-45 to DB-9 serial port adapter into the serial port on the management device.
Connect the other end of the Ethernet cable to the serial console port on the SRX345.
Start your asynchronous terminal emulation application (such as Microsoft Windows HyperTerminal) and select the appropriate COM port to use (for example, COM1).
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 SRX345 using a mini-USB console port. See the SRX345 Hardware Guide.

Perform Initial Configuration

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.
Enter configuration mode.
root> configure
[edit] root#
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
Retype new password: password
Issue the commit command to activate the candidate configuration that disables ZTP:
[edit] root# commit
Enable root login over SSH, and allow SSH access over the WAN interface (ge-0/0/0).
[edit] root# set system services sash root-login allow
root# set security zones security-zone untrusty interfaces ge-0/0/0.0 host- inbound-traffic system-services sash
Configure the hostname.
[edit] root# set system host-name hostname
That’s it! The initial configuration is complete. Commit the configuration to activate the changes on the SRX.
[edit] root# commit

Congratulations! Your SRX is Up and Running

Your SRX345 is now online and providing secure Internet access to devices attached to the LAN ports. You can manage the device locally and remotely, using the Junos CLI, J-Web, or a cloud based provisioning service. Here’s what your network looks like:
SRX is Up and Running

A few things to keep in mind about your new SRX345 branch network:

You access the SRX CLI or J-Web user interface locally using the 192.168.1.1 address. To access the SRX remotely, specify the IP address assigned by the WAN provider. Simply issue a show interfaces ge-0/0/0 terse CLI command to confirm the address in use by the WAN interface.
The management interface is configured as a DHCP server for the 192.168.1.0/24 subnet.
Devices attached to the LAN ports are configured to use DHCP. They receive their network configuration from the SRX. These devices obtain an IP address from the 192.168.2.0/24 address pool and use the SRX as their default gateway.
All LAN ports are in the same subnet with Layer 2 connectivity. All traffic is permitted between trust zone interfaces.
All traffic originating in the trust zone is permitted in the untrusty zone. Matching response traffic is allowed back from the untrusty to the trust zone. Traffic that originates from the untrusty zone is blocked from the trust zone.
The SRX performs source NAT (S-NAT) using the WAN interface’s IP for traffic sent to the WAN that originated from the trust zone.
Traffic associated with specific system services (HTTPS, DHCP, TFTP, and SSH) is permitted from the untrusty zone to the local host. All local host services and protocols are allowed for traffic that originates from the trust zone.
