Juniper SRX300 Series Setup guide

The SRX300 Services Gateway consolidates security, routing, switching,

and WAN interfaces for small retail oces. With advanced threat mitigation

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

connectivity.

With a desktop form-factor chassis, the SRX300 Services Gateway has six

1 G Ethernet ports, two 1 G SFP ports, 4 GB of DRAM memory, and 8 GB of

ﬂash memory.

Connect the Grounding Cable (Optional)

1. Connect the grounding cable to a proper earth ground.

2. 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.

3. Secure the grounding cable lug to the grounding point with the screw. Apply

between 6 in.-lb (0.67 Nm) and 8 in.-lb (0.9 Nm) of torque to the screw.

Power On the Device

NOTE: Before connecting the device to the power supply, attach an ESD

strap to an ESD point and place the other end of the strap around your

bare wrist.

1. Plug the DC connector end of the power cable into the power connector on

the rear of the device.

2. Plug the AC adapter end of the power cable into an AC power outlet.

3. Turn on the power to the AC power receptacle.

4. Note the following LED indications. Wait until the STATUS LED is solid green

before proceeding to the next step.

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.

g000737

SRX300

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 page 5.

2. Ensure that the management device acquires an IP address. The IP address

should be on the corresponding IP subnet for the interface you connected to

in step 1. The device functions as a DHCP server and will assign an IP address

to the management device.

For example, if you are connected to port 0/1, then the IP address of the

management device should be from the 192.168.1.x network. If an IP address

is not assigned to the management device, manually conﬁgure an IP address.

Do not assign the 192.168.1.1 IP address to the management device, as this IP

address is assigned to the device. You can use the ipconﬁg (or ifconﬁg for

Macintosh or Linux users) command to verify the IP address.

Refer to the Interfaces table on page 2 for information on the subnet for each

interface.

NOTE: To conﬁgure the device using the CLI, connect the RJ-45 cable

from the CONSOLE port to the supplied DB-9 adapter, which then

connects to the serial port on the management device (serial port

settings: 9600-N-1).

Alternately, you can use the USB cable to connect to the mini-USB

console port on the services gateway. To use the USB console port,

you must download a USB driver to the management device from

http://www.juniper.net/support/downloads/group/?f=junos.

How to Set Up Your SRX300 Services Gateway 5

1. Access the J-Web interface using the URL http://192.168.x.1, where x is the

port number to which you are connected on the services gateway. The

recommended browser is Mozilla Firefox version 23.x or later.

2. Select one of the following setup modes:

•Guided Setup (uses a static 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 only 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 static IP address. Ensure that

the cable connecting the ISP-supplied device to the SRX Series device is

ﬁrmly seated.

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

b. Internal zones

c. DMZ

5. Conﬁgure the security policy:

a. Licenses

b. DMZ policy

c. Internal policy

d. Remote access

6. Conﬁgure Network Address Translation:

a. Source NAT

b. 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 management zone IP. Click the URL for reconnection

instructions on the Conﬁrm & Apply page to reconnect, if required.

8. Click Done to complete the setup.

How to Set Up Your SRX300 Services Gateway 7

Conﬁgure the Device Using the Default Setup Mode

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

that the cable connecting the ISP-supplied device to the SRX Series device is

ﬁrmly seated.

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.

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 management zone IP. Click the URL for reconnection

instructions on the Conﬁrm & Apply page to reconnect, if required.

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 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 a rescue conﬁguration has been set, an amber ALARM LED

indicates a minor issue, and a solid red ALARM LED indicates a major

problem.
