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.

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.

Basic Connection and Configuration with the CLI

Step 2. Updating the JUNOS Software with the CLI
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. You can use the CLI, but we recommend the J-Web interface for the download.
To update the JUNOS software with the CLI:
1. Go to http://www.juniper.net/support, and follow the links to download the JUNOS
software for J-series routers to an FTP server.
2. Download the JUNOS software to the router with the CLI or J-Web interface:
root> request system software add validate unlink reboot source
For complete instructions, see the J-series Services Router Administration Guide.
Step 3. Adding Licenses with the CLI
If you purchased one or more licenses, you received an envelope with instructions
for obtaining license keys from the Web. To enable each license on the router, you
must add the license key. You can add one or more license keys from the CLI.
To add a license key and enable a license:
1. Follow the instructions in your license envelope to generate the license key from
the Web site.
2. Copy the license key onto the router with the CLI:
a. Type the following command, and press Enter:
root> request system license add terminal
b. When prompted, copy and paste the license key from the Web site at the
command line, separating multiple license keys with a blank line.
c. To exit license key entry, press Ctrl+D.
For complete instructions, see the Getting Started Guide for your router.
Step 4. Configuring Basic Settings with the CLI
In CLI configuration mode, you use the set command to enable features, and the
delete command to disable them. The commands you enter do not update the active
configuration on the router until you use the commit command.
To configure basic settings with the CLI:
1. From the CLI, enter configuration mode:
root> configure
root#
14 ■Basic Connection and Configuration with the CLI
J-series™Services Router Quick Start

2. Set the IP addresses of the built-in Ethernet ports. For example:
■On a J2300 router:
root# set interfaces fe-0/0/0 unit 0 family inet address 192.168.1.1/24
root# set interfaces fe-0/0/1 unit 0 family inet address 192.168.2.1/24
■On a J4350 or J6350 router:
root# set interfaces ge-0/0/0 unit 0 family inet address 192.168.1.1/24
root# set interfaces ge-0/0/1 unit 0 family inet address 192.168.2.1/24
root# set interfaces ge-0/0/2 unit 0 family inet address 192.168.3.1/24
root# set interfaces ge-0/0/3 unit 0 family inet address 192.168.4.1/24
The unit number is the logical interface number. IP addresses are configured on
the logical interface. Setting the protocol family to inet specifies the routing table
of IPv4 addresses.
3. Set a default route (default gateway) for IPv4 packets. For example:
root# set routing-options static route 192.168.1.254/24 next-hop 10.1.1.50
4. Configure one or more static routes:
root# set routing-options static route destination-prefix next-hop address
5. Set the hostname. For example:
root# set system host-name Chicago
6. Save your configuration settings and activate them on the Services Router:
root# commit

Safety Warnings Summary
NOTE: This is a summary of safety warnings. For a complete list of warnings, including
translations, see the Getting Started Guide for your router at
http://www.juniper.net/techpubs/.
WARNING: Certain ports on the router are designed for use as intrabuilding
(within-the-building) interfaces only (Type 2 or Type 4 ports as described in
GR-1089-CORE, Issue 4) and require isolation from the exposed outside plant (OSP)
cabling. To comply with NEBS requirements and protect against lightening surges
and commercial power disturbances, the intrabuilding ports must not be metallically
connected to interfaces that connect to the OSP or its wiring. The intrabuilding ports
on the router are suitable for connection to intrabuilding or unexposed wiring or
cabling only. The addition of primary protectors is not sufficient protection for
connecting these interfaces metallically to OSP wiring.
CAUTION: To comply with intrabuilding lightning and surge requirements,
intrabuilding wiring must be shielded, and the shield for the wiring must be grounded
at both ends.
CAUTION: Before removing or installing components of a router, attach an ESD strap
to an ESD point and place the other end of the strap around your bare wrist. Failure
to use an ESD strap could result in damage to the router.
CAUTION: For routers with AC power supplies, an external surge protective device
(SPD) must be used at the AC power source.

J-series™Services Router Quick Start

■Permit only trained and qualified personnel to install or replace Services Router
components.
■The equipment is suitable for installation in locations where the National Electrical
Code (NEC) applies, as well as in Network Telecommunication Facilities.
■Perform only the procedures described in this quick start and the Getting Started
Guide for your router. Other services must be performed by authorized service
personnel only.
■Before you connect a Services Router to a power source, read the installation
instructions in the Getting Started Guide for your router.
■Before installing the router, read the guidelines about preparing for router
installation in the Getting Started Guide for your router, to make sure that the
site meets power, environmental, and clearance requirements for the router.
■When installing the Services Router, do not use a ramp inclined at more than
10 degrees.
■We recommend that two people perform installation of J-series Services Routers.
Have one person lift the router into position and a second person secure the
mounting screws. To prevent injury, keep your back straight and lift with your
legs, not your back.
■Mount the Services Router at the bottom of the rack if it is the only unit in the
rack.
■When mounting the Services Router in a partially filled rack, load the rack from
the bottom to the top, with the heaviest component at the bottom of the rack.
■If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the Services Router in the rack.
■Grounding surfaces are to be cleaned and brought to a bright finish before
grounding connections can be made.
■When removing or installing an electrical component, always place it
component-side up on a flat antistatic surface or in an electrostatic bag.
■Do not work on the system or connect or disconnect cables during electrical
storms.
■Before working on equipment that is connected to power lines, remove jewelry,
including rings, necklaces, and watches. Metal objects heat up when connected
to power and ground and can cause serious burns or become welded to the
terminals.
■Failure to observe these safety warnings can result in serious physical injury.
