Juniper SRX320 Manual

The SRX320 Services Gateway consolidates security, routing, switching,

and WAN interfaces for small distributed enterprises. With advanced threat

mitigation capabilities, the services gateway provides cost-eective and secure

connectivity across distributed enterprises.

With a desktop form-factor chassis, the SRX320 Services Gateway has six

1-Gigabit Ethernet ports, two 1-Gigabit Ethernet SFP ports, 4 GB of DRAM

memory, and 8 GB of ﬂash memory. The SRX320 Services Gateway is available

with or without Power over Ethernet (PoE) capability. In the PoE model, the six

Ethernet ports are PoE capable.

the Device

Install the Device in a Rack

1. Position a mounting bracket on each side of the chassis. Use a number-1

Phillips screwdriver to install the screws that secure the mounting brackets

and power supply adapter tray to the chassis.

For 75 W power supply adapter:

2. Place the power supply adapter in the tray.

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.

5. Install the second screw in each mounting bracket.

g000951

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 SRX320 Services Gateway can also be mounted on a desk or a wall. For

details, see the SRX320 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.

NOTE: 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.

Conﬁgure the Device Using J-Web

To conﬁgure the device using J-Web, follow the steps in this section.

Connect the Management Device

1. To conﬁgure the device using J-Web (recommended), connect any of the

network ports numbered 0/1 through 0/5 to the Ethernet port on the

management device, using an RJ-45 cable.

g00097

Ethernet port

RJ-45 cable Ethernet port

NOTE: The ge-0/0/0 interface (port 0/0) is a WAN interface. Do not

use this port for the initial conﬁguration procedure.

If you will be using the Default setup mode to conﬁgure the device, use

only port 0/1. For information on the setup modes, see the following

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 subnetwork 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 subnetwork. 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-0/0/5). which is

conﬁgured with an IP address of 192.168.1.1/24.

How to Set Up Your SRX320 Services Gateway 5

1. Access the J-Web interface using the URL https://192.168.1.1. The

recommended browser is Internet Explorer version 9 or 10, or Mozilla Firefox

version 38 (or later).

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. Connect port 0/0 to the ISP device to obtain a dynamic IP address.

2. Select the expertise level as Basic or Expert.

The following table compares the Basic and Expert levels:

3. Conﬁgure the basic settings:

a. Device name

b. Password for the root account

c. Time

4. Conﬁgure the security topology:

a. Internet zone (Untrust)

b. Internal zones (Trust)

c. DMZ

5. Conﬁgure the security policy:

a. Licenses (Security services)

b. DMZ policy

c. Internet and internal policies

d. Remote VPN

6. Conﬁgure Network Address Translation:

a. Internal Source NAT

b. Internal Destination NAT

c. DMZ Destination NAT

7. 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.

8. Click Done to complete the setup.

Conﬁgure the Device Using the Default Setup Mode

1. Connect port 0/0 to the ISP device to obtain a dynamic IP address.

NOTE: Verify that the management device is connected to port 0/1 on

the services gateway before proceeding to the next step.

2. Conﬁgure the basic settings – device name, root account information, and

system time.

How to Set Up Your SRX320 Services Gateway 7

3. Conﬁgure the security policy – licenses.

4. Review the settings and click Apply Settings. Click Done to complete the

setup.

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.

You can also conﬁgure the services gateway using the CLI, by connecting to the

Console port. For details, see the SRX320 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 SRX320 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 Conﬁguration Wizards > 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.

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.
