3. Have one person grasp the sides of the device, lift it, and position it in the rack.

Align the bottom hole in each mounting bracket with a hole in each rack rail,

making sure that the chassis is level.

4. Have a second person install a mounting screw into each of the two aligned

holes. Use a number-3 Phillips screwdriver to tighten the mounting screws.

g005162

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.

NOTE: The ge-0/0/0 and ge-0/0/7 interfaces (ports 0/0 and 0/7)

are WAN interfaces. Do not use these ports for the initial conﬁguration

procedure.

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.

How to Set Up Your SRX300 Services Gateway 6

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.

Conﬁgure the Device Using the Guided Setup Mode

1. Select the expertise level as Basic or Expert.

The following table compares the Basic and Expert levels:

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.
