Revision 1

J-series Services Routers provide IP routing, WAN and LAN connectivity, and

management services. Available in several models, Services Routers typically connect

small, branch, or regional offices to a central site, and link Internet service provider

(ISP) networks.

The J-series Services Router Quick Start provides instructions to initially set up J2300,

J2320, J2350, J4350, and J6350 Services Routers. You need no previous JUNOS

software experience, but must have managed a network and configured other routers.

For more information, see the J-series documentation at http://www.juniper.net/techpubs.

J-series™Services Router Quick Start

What You Need To Know

Management IP Address

When you first connect a management PC or laptop to a built-in Ethernet port on a

Services Router, the router acts as a DHCP client and attempts to perform an

autoinstallation. If it does not find a DHCP server, the router assigns 192.168.1.1/24

as the IP address for port 0. (If you are connected to port 1, 192.168.2.1/24 is

assigned as the IP address. On the J2320, J2350, J4350 and J6350 routers, port 2

and port 3 are assigned 192.168.3.1/24 and 192.168.4.1/24, respectively.)

Because this address is not part of any explicit configuration, it is removed when

you change the configuration in any way. You must configure an IP address for this

LAN port when you commit your initial configuration. (See “Step 4. Configuring Basic

Settings with J-Web Quick Configuration”on page 11 or “Step 4. Configuring Basic

Settings with the CLI”on page 14.)

J-Web Access

The Web interface to the router—called the J-Web interface—is enabled by default.

To configure the router with the Web interface, you attach a PC or laptop to a built-in

Ethernet port. The examples in this document use the first built-in Ethernet port:

■On J2300 routers, the first built-in Ethernet port is Fast Ethernet PORT 0 (internally

named fe-0/0/0).

■On J2320, J2350, J4350 and J6350 routers, the first built-in Ethernet port is

Gigabit Ethernet port 0/0 (internally named ge-0/0/0).

See “Step 1. Connecting, Logging In, and Starting the J-Web Interface”on page 9.

CLI Console Access

Services Routers are shipped with a console cable and adapter. To configure a Services

Router through the console port with the JUNOS command-line interface (CLI), you

use a terminal emulation program such as Microsoft Windows HyperTermimal. (See

“Step 1. Connecting, Logging In, and Starting the CLI”on page 13.)

Required Licenses

To use the following features on a Services Router, you must purchase a license. (See

“Step 3. Adding Licenses with the CLI”on page 14 or “Step 4. Configuring Basic

Settings with J-Web Quick Configuration”on page 11.)

■Advanced Border Gateway Protocol (BGP) support for route reflectors

■Data link switching (DLSw)

■J-Flow traffic analysis

What You Need To Know ■3

What You Need To Know

Slot Numbers

J2300 routers have built-in WAN ports. Other models have slots for replaceable

Physical Interface Modules (PIMs):

■J2320 Services Routers—Slots 1 through 3 are numbered from top to bottom

and left to right.

■J2350 Services Routers—Slots 1 through 5 are numbered from top to bottom

and left to right.

■J4350 and J6350 Services Routers—Slots 1 through 6 are numbered from top to

bottom and left to right.

Interfaces and Ports

Interfaces are named by type, slot number, module number (always 0), and port

number. Port numbering starts with 0. For example:

■On J2300 routers, built-in Fast Ethernet LAN PORT 0 and PORT 1, which are in

slot 0, are named fe-0/0/0 and fe-0/0/1.

■On J2320, J2350, J4350, and J6350 routers, the built-in Gigabit Ethernet LAN

ports 0/0 through 0/3, which are in slot 0, are named ge-0/0/0, ge-0/0/1,

ge-0/0/2, and ge-0/0/3.

■On models with replaceable PIMs, the first port on a T1 PIM in slot 1 is named

t1-1/0/0.

Remote Access

Although Telnet and SSH are both supported, they are disabled by default.

b. Remove the clear plastic cover protecting the terminal block.

c. Remove the two center screws next to the labels –48 VDC and RTN.

d. Secure the positive (+) DC source power cable lug to the RTN terminal,

tightening the screw only until snug. Do not overtighten.

e. Secure the negative (–) DC source power cable lug to the –48 VDC terminal,

tightening the screw only until snug. Do not overtighten.

f. Replace the plastic cover.

4. Repeat Step 2 or Step 3 for the second power supply, if one is installed.

For complete instructions, see the Getting Started Guide for your router.

Basic Connection and Configuration with the J-Web Interface

For J-Web access, you connect from your management PC or laptop to the Services

Router through one of the built-in Ethernet interfaces. The examples in this document

use port 0. (For information about the J-Web interface, see “J-Web Basics”on page 15.)

Step 1. Connecting, Logging In, and Starting the J-Web Interface

When the Services Router is powered on for the first time, it searches for a DHCP

server, and if it does not find one, it assigns an IP address within the 192.168.1.0/24

subnetwork to any devices connected to it.

To connect to the J-Web interface through port 0/0 on the router:

Basic Connection and Configuration with the J-Web Interface ■9

Basic Connection and Configuration with the J-Web Interface

1. On the management device, such as a PC or laptop, you use to access the J-Web

interface, verify that the address of the port that you connect to the router is set

to one of the following:

■An Ethernet address on the 192.168.1/24 subnetwork other than

192.168.1.1

■An Ethernet address from a DHCP server

2. Turn off the power to the management device.

3. Plug one end of the Ethernet cable into the Ethernet port on the management

device.

4. Connect the other end of the Ethernet cable to the built-in Ethernet port on the

router.

5. Power on the router by pressing the power button on the front panel.

6. Wait until the STATUS LED on the front panel turns solid green.

7. Turn on the power to the management device. The router assigns an IP address

to the management device within the 192.168.1/24 subnetwork if the device

is configured to use DHCP.

8. From the management device, open a Web browser and enter the IP address

192.168.1.1 in the address field. The Set Up Quick Configuration page appears.

9. Configure basic settings for your router as described in “Step 4. Configuring Basic

Settings with J-Web Quick Configuration”on page 11.

NOTE: You must manually configure the IP address for the management port you

are using before you save your initial configuration. When you save the configuration

for the first time, the DHCP lease is lost and you will lose the connection to the router

if you have not manually configured the IP address. If you lose connection through

the management interface, you must connect through the console port.

Step 2. Updating the Software with the J-Web Interface

After starting up the Services Router, you might want to download the latest version

of the JUNOS software from the Juniper Networks Web site and load it onto the

router. To update the JUNOS software:

1. Go to http://www.juniper.net/support, and follow the links to download the JUNOS

software for J-series routers to your PC or laptop.

2. Log in to the J-Web interface.

3. Click Manage>Software>Upload software package.

4. Click Browse, locate the JUNOS software package file on your PC or laptop hard

drive, and open the file.

5. Select the check box next to Reboot If Required, and click Upload Package.

For complete instructions, see the J-series Services Router Administration Guide.
