5. Install the second screw in each mounting bracket.
6. Verify that the mounting screws on one side of the rack are aligned with the
mounting screws on the opposite side and that the device is level.
The SRX300 Services Gateway can also be mounted on a desk or a wall. For
details, see the SRX300 Services Gateway Hardware Guide.
NOTE: The mounting kits are not shipped with the device and must be
ordered separately.
Connect the Grounding Cable (Optional)
1. Attach an ESD strap to an ESD point and place the other end of the strap
around your bare wrist.
2. Connect the grounding cable to a proper earth ground.
3. Place the grounding cable lug over the grounding point on the rear of the
chassis.
CAUTION: A licensed electrician must attach a cable lug to the
grounding cable. A cable with an incorrectly attached lug can damage
the device.
4. Secure the grounding cable lug to the grounding point with the screw.

2. The services gateway functions as a DHCP server and automatically assigns
an IP address to the management device. Ensure that the management
device acquires an IP address on the 192.168.1.0/24 network from the device.
If an IP address is not assigned to the management device, manually
configure an IP address in the 192.168.1.0/24 network. Do not assign the
192.168.1.1 IP address to the management device, as this IP address is assigned
to the services gateway. By default, the DHCP server is enabled on the L3
VLAN interface, irb.0 (interface ge-0/0/1 to ge-0/0/6), which is configured
with an IP address of 192.168.1.1/24.
3. Connect port 0/0 or 0/7 to the ISP device to obtain a dynamic IP address.
4. Access the J-Web interface (https://192.168.1.1). The recommended browser
is Internet Explorer version 10 or 11, Mozilla Firefox version 46 (or later), or
Google Chrome 55 (or later).
To configure the device using Zero Touch Provisioning, follow the procedure in
the “Configure the Device Using ZTP with Juniper Networks Network Service
Controller” section.
To configure the device using J-Web, click Skip to J-Web and follow the
procedure in the “Configure the Device Using J-Web” section.
Configure the Device Using ZTP with Juniper Networks
Network Service Controller
Zero Touch Provisioning (ZTP) enables you to complete the initial configuration
of the SRX300 Services Gateway in your network automatically, with minimum
intervention.
Network Service Controller is a component of the Juniper Networks Contrail
Service Orchestration platform that simplifies and automates the design and
implementation of custom network services that use an open framework.
For more information, refer to the Network Service Controller section
in the datasheet at http://www.juniper.net/assets/us/en/local/pdf/
datasheets/1000559-en.pdf.
To configure the device automatically using ZTP:
NOTE: To complete the ZTP process, ensure that the services gateway
is connected to the Internet. See the “Connect the Management Device”
section.
•If you already have the authentication code, enter the code in the webpage
displayed.
On successful authentication, the initial configuration is applied and
committed on the services gateway. Optionally, the latest Junos OS image is
installed on the device before the initial configuration is applied.
•If you do not have the authentication code, you can use the J-Web setup
wizard to configure the services gateway. Click Skip to J-Web and follow the
procedure in the “Configure the Device Using J-Web” section.

Configure the Device Using J-Web
To configure the device using J-Web, follow the steps in this section.
1. Enter the root authentication password.
2. Select one of the following setup modes:
•Guided Setup (uses a dynamic IP address)—Allows you to set up the
device in a custom security configuration. You can select either the Basic
or the Expert option.
•Default Setup (uses a dynamic IP address)—Allows you to quickly set up
the device with the default configuration. Any additional configuration can
be done after the wizard setup is completed.
•High Availability—Allows you to set up a chassis cluster with a default basic
configuration.
NOTE: The initial configuration requires that you specify the device
name and root password. You can skip all the other steps and go
directly to the Confirm & Apply page to apply the configuration.

2. Configure the basic settings:
a. Device name
b. Password for the root account (Use the password that you entered in
Step 1 of the “Configure the Device Using J-Web” section.)
c. Time
3. Configure the security topology:
a. Internet zone (Untrust)
b. Internal zones (Trust)
c. DMZ
4. Configure the security policy:
a. Licenses (Security services)
b. DMZ policy
c. Internet and internal policies
d. Remote VPN
5. Configure Network Address Translation:
a. Internal Source NAT
b. Internal Destination NAT
c. DMZ Destination NAT
6. Review the settings and click Apply Settings.
NOTE: Check the connectivity from the management device to the
SRX Series device. You might lose connectivity to the SRX Series device
if you have changed the internal zone IP. Click the URL for reconnection
instructions on the Confirm & Apply page to reconnect, if required.
7. Click Done to complete the setup.

How to Set Up Your SRX300 Services Gateway 8
Configure the Device Using the Default Setup Mode
1. Configure the basic settings – device name, root account information, and
system time.
2. Configure the security policy – licenses.
3. Review the settings and click Apply Settings. Click Done to complete the
setup.
You can also configure the services gateway using the CLI, by connecting to the
Console port. For details, see the SRX300 Services Gateway Hardware Guide.
Verify the Settings
Access http://www.juniper.net to ensure that you are connected to the Internet.
This connectivity ensures that you can pass trac through the services gateway.
If the page does not load, perform the following checks to see if you can identify
the problem:
•Verify your configuration settings, and ensure that you have applied the
configuration.
•Check if the ISP-supplied device connecting your SRX Series device to the
Internet is turned on and working properly. Try turning it o and on again.
After you complete these steps, the SRX Series device can pass trac from any
trust port to the untrust port.
NOTE: With this step, you have successfully completed the initial
configuration, and your SRX300 Services Gateway is ready for use.
Change the Configuration Settings (Optional)
After you complete the initial setup configuration, you can access the J-Web
setup wizard by clicking Configure > Device Setup > Set Up. You can either
edit the existing settings or create a new configuration. If you choose to create
a new configuration, then all the current configuration in the services gateway
will be deleted.

How to Set Up Your SRX300 Services Gateway 9
Power O the Device
You can power o the device in one of the following ways:
• Graceful shutdown—Press and immediately release the Power button.
• Forced shutdown—Press the Power button, and hold it for 10 seconds.
After powering o a power supply, wait at least 60 seconds before turning it
back on.
Reset the Configuration
Use the RESET CONFIG button to restore the device to the factory-default
configuration or to a rescue configuration. To press the RESET CONFIG button,
insert a small probe (such as a straightened paper clip) into the pinhole on the
front panel.
Pressing and quickly releasing the RESET CONFIG button loads and commits
the rescue configuration. The rescue configuration is a previously committed,
valid configuration set through J-Web or the CLI. The STATUS LED is solid amber
during this time.
Pressing and holding the RESET CONFIG button for 15 seconds or more,
until the STATUS LED is solid amber, deletes all configurations (backup
configurations and rescue configuration), and loads and commits the factory
configuration.
NOTE: After resetting the device, check the device status by viewing
the LEDs on the front panel. For information on the LED states, see the
“Power On the Device“ section.
