READ THIS END USER LICENSE AGREEMENT (“AGREEMENT”) BEFORE DOWNLOADING, INSTALLING, OR USING THE SOFTWARE. BY DOWNLOADING,
INSTALLING, OR USING THE SOFTWARE OR OTHERWISE EXPRESSING YOUR AGREEMENT TO THE TERMS CONTAINED HEREIN, YOU (AS CUSTOMER
OR IF YOU ARE NOT THE CUSTOMER, AS A REPRESENTATIVE/AGENT AUTHORIZED TO BIND THE CUSTOMER) CONSENT TO BE BOUND BY THIS
AGREEMENT. IF YOU DO NOT OR CANNOT AGREE TO THE TERMS CONTAINED HEREIN, THEN (A) DO NOT DOWNLOAD, INSTALL, OR USE THE SOFTWARE,
AND (B) YOU MAY CONTACT JUNIPER NETWORKS REGARDING LICENSE TERMS.
1. The Parties. The parties to this Agreement are Juniper Networks, Inc. and its subsidiaries (collectively “Juniper”), and the person or organization that
originally purchased from Juniper or an authorized Juniper reseller the applicable license(s) for use of the Software (“Customer”) (collectively, the “Parties”).
2. The Software. In this Agreement, “Software” means the program modules and features of the Juniper or Juniper-supplied software, and updates and
releases of such software, for which Customer has paid the applicable license or support fees to Juniper or an authorized Juniper reseller. “Embedded
Software” means Software which Juniper has embedded in the Juniper equipment.
3. License Grant. Subject to payment of the applicable fees and the limitations and restrictions set forth herein, Juniper grants to Customer a non-exclusive

e. The Global Enterprise Edition of the Steel-Belted Radius software may be used by Customer only to manage access to Customer’s enterprise network.
Specifically, service provider customers are expressly prohibited from using the Global Enterprise Edition of the Steel-Belted Radius software to support any
commercial network access services.
The foregoing license is not transferable or assignable by Customer. No license is granted herein to any user who did not originally purchase the applicable
license(s) for the Software from Juniper or an authorized Juniper reseller.
4. Use Prohibitions. Notwithstanding the foregoing, the license provided herein does not permit the Customer to, and Customer agrees not to and shall
not: (a) modify, unbundle, reverse engineer, or create derivative works based on the Software; (b) make unauthorized copies of the Software (except as
necessary for backup purposes); (c) rent, sell, transfer, or grant any rights in and to any copy of the Software, in any form, to any third party; (d) remove
any proprietary notices, labels, or marks on or in any copy of the Software or any product in which the Software is embedded; (e) distribute any copy of
the Software to any third party, including as may be embedded in Juniper equipment sold in the secondhand market; (f) use any ‘locked’ or key-restricted
feature, function, service, application, operation, or capability without first purchasing the applicable license(s) and obtaining a valid key from Juniper, even
if such feature, function, service, application, operation, or capability is enabled without a key; (g) distribute any key for the Software provided by Juniper
to any third party; (h) use the Software in any manner that extends or is broader than the uses purchased by Customer from Juniper or an authorized Juniper
reseller; (i) use the Embedded Software on non-Juniper equipment; (j) use the Software (or make it available for use) on Juniper equipment that the Customer
did not originally purchase from Juniper or an authorized Juniper reseller; (k) disclose the results of testing or benchmarking of the Software to any third
party without the prior written consent of Juniper; or (l) use the Software in any manner other than as expressly provided herein.
5. Audit. Customer shall maintain accurate records as necessary to verify compliance with this Agreement. Upon request by Juniper, Customer shall furnish
such records to Juniper and certify its compliance with this Agreement.
6. Confidentiality. The Parties agree that aspects of the Software and associated documentation are the confidential property of Juniper. As such, Customer
shall exercise all reasonable commercial efforts to maintain the Software and associated documentation in confidence, which at a minimum includes
restricting access to the Software to Customer employees and contractors having a need to use the Software for Customer’s internal business purposes.
■iii
7. Ownership. Juniper and Juniper's licensors, respectively, retain ownership of all right, title, and interest (including copyright) in and to the Software,

if the Software is embedded in another Juniper product, the price paid by Customer for such other product. Customer acknowledges and agrees that Juniper
has set its prices and entered into this Agreement in reliance upon the disclaimers of warranty and the limitations of liability set forth herein, that the same
reflect an allocation of risk between the Parties (including the risk that a contract remedy may fail of its essential purpose and cause consequential loss),
and that the same form an essential basis of the bargain between the Parties.
9. Termination. Any breach of this Agreement or failure by Customer to pay any applicable fees due shall result in automatic termination of the license
granted herein. Upon such termination, Customer shall destroy or return to Juniper all copies of the Software and related documentation in Customer’s
possession or control.

15. Miscellaneous. This Agreement shall be governed by the laws of the State of California without reference to its conflicts of laws principles. The provisions
of the U.N. Convention for the International Sale of Goods shall not apply to this Agreement. For any disputes arising under this Agreement, the Parties
hereby consent to the personal and exclusive jurisdiction of, and venue in, the state and federal courts within Santa Clara County, California. This Agreement
constitutes the entire and sole agreement between Juniper and the Customer with respect to the Software, and supersedes all prior and contemporaneous
agreements relating to the Software, whether oral or written (including any inconsistent terms contained in a purchase order), except that the terms of a
separate written agreement executed by an authorized Juniper representative and Customer shall govern to the extent such terms are inconsistent or conflict
with terms contained herein. No modification to this Agreement nor any waiver of any rights hereunder shall be effective unless expressly assented to in
writing by the party to be charged. If any portion of this Agreement is held invalid, the Parties agree that such invalidity shall not affect the validity of the
remainder of this Agreement. This Agreement and associated documentation has been written in the English language, and the Parties agree that the English
version will govern. (For Canada: Les parties aux présentés confirment leur volonté que cette convention de même que tous les documents y compris tout
avis qui s'y rattaché, soient redigés en langue anglaise. (Translation: The parties confirm that this Agreement and all related documentation is and will be

Overview of Services Routers
J-series Services Routers provide stable, reliable, and efficient IP routing, WAN and
LAN connectivity, and management services for small to medium-sized enterprise
networks. Services Routers typically connect small, branch, or regional offices to a
central site router, and link Internet service provider (ISP) networks.
All J-series Services Routers run the JUNOS Internet software, which offers many
advanced routing and security services. For more information about software features,
see “J-series Software Features and Licenses” on page 7. A single, common JUNOS
code base simplifies deployment, patches, and software upgrades.
You can use two user interfaces to monitor, configure, troubleshoot, and manage a
Services Router:
■J-Web interface—A Web-based graphical interface that allows you to operate a
router without commands. The J-Web interface provides access to all JUNOS
functionality and features. Quick Configuration wizards simplify basic
configuration and minimize the risk of operator error.
■JUNOS command-line interface—A Juniper Networks command shell that runs
on top of a UNIX-based operating system kernel. The CLI is a straightforward
command interface. On a single line, you type commands that are executed
when you press the Enter key. The CLI provides command Help and command
completion.
For an introduction to the J-Web and CLI interfaces, see “Services Router User
Interface Overview” on page 79. For more information, see the J-Web Interface UserGuide and the JUNOS CLI User Guide.

J2320 and J2350 Chassis
The J2320 and J2350 chassis is a rigid sheet metal structure that houses all the other
router components (see Figure 1 on page 14 through Figure 7 on page 17). The
chassis can be installed in many types of racks or cabinets. For information about
acceptable rack types, see “Rack Requirements” on page 102.
In addition to the components described in subsequent sections, the chassis includes
the following components:
■Mounting brackets—One pair of metal brackets can be mounted at the front or
center of the chassis for mounting the chassis in a rack or cabinet.
■Earthing terminal—A protective earthing terminal and a PEM nut at the rear of
the chassis ensure safe dissipation of static electricity in all situations.
■ESD point—One electrostatic discharge (ESD) point, a banana plug receptacle at
the front of the chassis, minimizes the risk of electrical discharge in potentially
hazardous environments.
CAUTION: Before removing or installing components of a functioning 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.
The router must be connected to earth ground during normal operation. The protective
earthing terminal on the rear of the chassis is provided to connect the router to
ground (see Figure 3 on page 15). Additional grounding is provided to an AC-powered
router when you plug its power supply into a grounded AC power receptacle.
For additional safety information, see “Safety and Regulatory Compliance
Information” on page 245.

J2320 and J2350 Midplane
The J2320 and J2350 midplane is located in the center of the chassis and forms the
rear of the PIM card cage (see Figure 6 on page 16 and Figure 7 on page 17). You
install the PIMs into the midplane from the front of the chassis. Data packets are
transferred across the midplane from the PIM to the Routing Engine, and from the
Routing Engine across the midplane to the destination PIM.
A time-division multiplexing (TDM) bus in J2320 and J2350 routers provides support
for the Avaya VoIP module TGM550. The TGM550 converts the voice path from the
TDM bus to compressed or uncompressed and packetized VoIP on an Ethernet
connection. For more information, see “PIM and VoIP Module Overview” on page 43.
J2320 and J2350 Routing Engine Hardware
The Routing Engine consists of the following components. For more information,
see “Software Overview” on page 39.
■Processor—Creates the packet forwarding switch fabric for the router and runs
JUNOS Internet software to maintain the router's routing tables and routing
protocols.
■DRAM—Buffers incoming packets and provides storage for the routing and
forwarding tables and for other Routing Engine processes.
To view the amount of DRAM installed on your router, issue the show chassis
routing-engine command.
■EPROM—Stores the serial number of the Routing Engine.
To view the serial number of the Routing Engine, issue either the show chassis
routing-engine command or the show chassis hardware command.
■Crypto Accelerator Module—Processor card that enhances performance of
cryptographic algorithms used in IP security (IPSec) services. The cryptographic
algorithms supported include Advanced Encryption Standard (AES), Data
Encryption Standard (DES), triple DES (3DES), Hashed Message Authentication
Code-Message Digest 5 (HMAC-MD5), and HMAC-Secure Hash Algorithm 1
(SHA-1). The Crypto Module is an optional feature of J2320 and J2350 Services
Routers.
To determine whether there is a Crypto Accelerator Module installed on your
router, issue the show chassis hardware command.
■Compact flash—Provides primary storage for software images, configuration
files, and microcode. J-series routers have a primary or internal compact flash
located on the system board. For information about replacing the internal
compact flash, see “Replacing Internal Compact Flashes on J2320 and J2350
Routers” on page 180.
J2320 and J2350 Services Routers also provide a slot in the rear of the chassis
into which you can insert an additional external compact flash. For information
about external compact flashes, see “J2320 and J2350 External Compact
Flashes” on page 24.
18■J2320 and J2350 Services Router Hardware Features
J2320 and J2350 Boot Devices
J2320 and J2350 Services Routers can boot from three devices:
■Internal compact flash
■External compact flash (also known as the removable compact flash)
■USB storage device
Normally, a J2320 or J2350 Services Router boots from the internal compact flash.
If the internal compact flash fails, the router attempts to boot from the external
compact flash if it is installed. If the external compact flash is not present or fails,
the router attempts to boot from the USB storage device.
J2320 and J2350 Front Panel
The front panel of a J2320 or J2350 Services Router (see Figure 8 on page 19 and
Figure 9 on page 19) allows you to install or remove PIMs, view router status LEDs,
access the console port, and perform simple control functions.

Power Button and POWER LED
The power button is located on the left side of the front panel (see
Figure 1 on page 14). You can use the power button to power the Services Router
on and off. When you power on the router, the Routing Engine boots as the power
supply completes its startup sequence.
The POWER LED is located to the upper left of the LED dashboard. Table 7 on page
21 describes the POWER LED.

After the router is powered on, status indicators—such as LEDs on the front panel
and show chassis command output—can take up to 60 seconds to indicate that the
power supply is functioning normally. Ignore error indicators that appear during the
first 60 seconds.
If you need to power off the router after the Routing Engine finishes booting, use the
J-Web interface or the CLI to halt the Services Router first. For instructions, see the
J-series Services Router Administration Guide. Alternatively, you can press and release
the power button to gracefully shut down the router. For more information, see
“Powering a Services Router On and Off” on page 127.
STATUS LED
When the system is powered on, the STATUS LED changes from off to blinking green.

HA LED
The HA (high availability) LED is for future use. The LED lights when the router starts,
but otherwise remains unlit.
RESET CONFIG Button
Use the RESET CONFIG button to return the router to either the rescue configuration
or the factory default configuration. The button is recessed to prevent it from being
pressed accidentally. To press this button insert a small probe (such as a straightened
paper clip) into the pinhole on the front panel (see Figure 8 on page 19 and
Figure 9 on page 19).
For example, if someone inadvertently commits a configuration that denies
management access to a Services Router, you can delete the invalid configuration
and replace it with a rescue configuration by pressing the RESET CONFIG button. You
must have previously set the rescue configuration through the J-Web interface or the
CLI. The rescue configuration is a previously committed, valid configuration.
CAUTION: Pressing and holding the RESET CONFIG button for 15 seconds or
more—until the STATUS LED blinks red—deletes all configurations on the router,
including the backup configurations and rescue configuration, and loads and commits
the factory configuration.

Chapter 2: System Overview
You can change the default behavior of the RESET CONFIG button. For more
information, see the J-series Services Router Basic LAN and WAN Access ConfigurationGuide.
Built-In Gigabit Ethernet Ports
Four built-in Gigabit Ethernet ports provide LAN connections over copper interfaces
to hubs, switches, local servers, and workstations. You can also designate an Ethernet
port for management traffic. When configuring one of these ports, you use the
interface name that corresponds to the port’s location. From left to right on the front
panel, the interface names for the ports are ge-0/0/0, ge-0/0/1, ge-0/0/2, and
ge-0/0/3.
For Gigabit Ethernet port pinout information, see “Gigabit Ethernet uPIM RJ-45

USB Port
The USB ports on the front panel of the router (see Figure 8 on page 19 and
Figure 9 on page 19) accept a USB storage device or USB storage device adapter with
a compact flash installed, as defined in the CompactFlash Specification published by
the CompactFlash Association. When a USB storage device is installed and configured,
it automatically acts as a secondary boot device if the internal compact flash fails on
startup. Depending on the size of the USB storage device, you can also configure it
to receive any core files generated during a failure. For information about configuring
a USB storage device, see the J-series Services Router Administration Guide.
NOTE: For a list of supported USB storage devices, see the J-series Services Router
Release Notes at http://www.juniper.net.
J2320 and J2350 External Compact Flashes
J2320 Power System
On J2320 and J2350 routers, an external compact flash, also known as removable
compact flash, accepts a type I or II compact flash, as defined in the CompactFlashSpecification published by the CompactFlash Association. The J2320 and J2350 chassis
has a slot on the rear for external compact flashes (see Figure 3 on page 15). When
the external compact flash is installed and configured, it automatically acts as the
secondary boot device if the internal compact flash fails on startup.
Depending on the capacity of the external compact flash, you can also configure it
to receive any core files generated during a failure. For information about configuring
an external compact flash, see the J-series Services Router Administration Guide.
The J2320 Services Router uses AC power (see Figure 3 on page 15). The autosensing
power supply distributes the different output voltages to the router components
according to their voltage requirements. The power supply is fixed in the chassis,
and is not field-replaceable.
The AC power supply has a single AC appliance inlet that requires a dedicated AC
power feed.
The J2320 AC-powered chassis has a power switch and does not include a power
LED.
For information about site power preparations, see “Power Guidelines, Requirements,
and Specifications” on page 105. For information about connecting the router to power
and ground, see “Connecting Power” on page 122.
J2350 Power System
The J2350 Services Router uses either AC or DC power. The autosensing power supply
(see Figure 4 on page 15 or Figure 5 on page 16) distributes the different output
voltages to the router components according to their voltage requirements. The
power supply is fixed in the chassis, and is not field-replaceable.
24■J2320 and J2350 Services Router Hardware Features
Chapter 2: System Overview
The AC power supply has a single AC appliance inlet that requires a dedicated AC
power feed. The DC power supply has a terminal block that provides a single DC
input (–48 VDC and return) and requires a dedicated 15 A (–48 VDC) circuit breaker.
The J2350 AC-powered or DC-powered chassis has a power switch and does not
include a power LED.
For information about site power preparations, see “Power Guidelines, Requirements,
and Specifications” on page 105. For information about connecting the router to power
and ground, see “Connecting Power” on page 122.
NOTE: You cannot mix DC and AC power supplies in the same chassis.
WARNING: DC-powered Services Routers are intended for installation only in a
restricted access location.
J2320 and J2350 Cooling System
The cooling system in J2320 and J2350 routers is from side to side. The J2320 router
has five cooling fans and the J2350 router has four cooling fans. The fans draw air
through vents along the left side of the chassis and exhaust it through vents on the
right side of the chassis. The airflow produced by these fans keeps router components
within the acceptable temperature range (see Figure 11 on page 26 and
Figure 12 on page 26). The speed of the fans is adjusted automatically according to
the current temperature.
On J2350 routers that comply with Network Equipment Building System (NEBS)
criteria, an air filter protects the air intake opening at the front of the chassis and
must be replaced periodically. To verify that the system is a NEBS-compliant system,
run the show chassis hardware command. A NEBS-compliant system displays the
term NEBS in the output. For instructions on how to replace air filters, see “Replacing
Air Filters on J2350 Routers” on page 207.
The Routing Engine monitors the temperature of the router components. If the
maximum temperature specification, as measured at the CPU junction, is exceeded
and the router cannot be adequately cooled, the Routing Engine shuts down the
hardware components.
J2320 and J2350 routers shut down when the CPU temperature reaches 80°C (176°F).
There is no alarm for temperature. You can view the CPU junction temperature using
the show chassis routing-engine command. The CPU temperature runs a few degrees
higher than the routing engine temperature displayed on the Monitor>Chassis page
of the J-Web interface.
An additional fan is part of each power supply. This fan is not regulated by the
operating system.

J4350 and J6350 Chassis
The J4350 and J6350 chassis is a rigid sheet metal structure that houses all the other
router components (see Figure 13 on page 28 through Figure 18 on page 30). The
chassis can be installed in many types of racks or cabinets. For information about
acceptable rack types, see “Rack Requirements” on page 102.
In addition to the features described in subsequent sections, the chassis includes the
following features:
■Mounting brackets—One pair of metal brackets can be mounted at the front or
center of the chassis. Use the brackets for mounting the chassis in a rack or
cabinet.
Chapter 2: System Overview
■Earthing terminals—Two protective earthing terminals, PEM nuts at the rear of
the chassis ensure safe dissipation of static electricity in all situations.
■ESD point—One electrostatic discharge (ESD) point, a banana plug receptacle at
the front of the chassis, minimizes the risk of electrical discharge in potentially
hazardous environments.
CAUTION: Before removing or installing components of a functioning 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.
The router must be connected to earth ground during normal operation. The protective
earthing terminals on the rear of the chassis are provided to connect the router to
ground (see Figure 14 on page 28). Additional grounding is provided to an AC-powered
router when you plug its power supply into a grounded AC power receptacle.
For additional safety information, see “Safety and Regulatory Compliance

The midplane is located in the center of the chassis and forms the rear of the PIM
card cage (see Figure 18 on page 30). You install the PIMs into the midplane from
the front of the chassis. Data packets are transferred across the midplane from the
PIM to the Routing Engine, and from the Routing Engine across the midplane to the
destination PIM.
J4350 and J6350 Routing Engine Hardware
The Routing Engine consists of the following components. For more information,
see “Software Overview” on page 39.
■Processor—Creates the packet forwarding switch fabric for the router and runs
JUNOS Internet software to maintain the router's routing tables and routing
protocols.
■DRAM—Buffers incoming packets and provides storage for the routing and
forwarding tables and for other Routing Engine processes.
Chapter 2: System Overview
To view the amount of DRAM installed on your router, issue the show chassis
routing-engine command.
■EPROM—Stores the serial number of the Routing Engine.
To view the serial number of the Routing Engine, issue either the show chassis
routing-engine command or the show chassis hardware command.
■Crypto Accelerator Module—Processor card that enhances performance of
cryptographic algorithms used in IP security (IPSec) services. The cryptographic
algorithms supported include Advanced Encryption Standard (AES), Data
Encryption Standard (DES), triple DES (3DES), Hashed Message Authentication
Code-Message Digest 5 (HMAC-MD5), and HMAC-Secure Hash Algorithm 1
(SHA-1).
To determine whether there is a Crypto Accelerator Module installed on your
router, issue the show chassis hardware command.
■Compact flash—Provides primary storage for software images, configuration
files, and microcode. J4350 and J6350 routers have a slot on the motherboard
for an internal compact flash. For information about replacing the compact flash,
see “Replacing Internal Compact Flashes on J4350 and J6350
Routers” on page 183.
J4350 and J6350 Boot Devices

For example, if someone inadvertently commits a configuration that denies
management access to a Services Router, you can delete the invalid configuration
and replace it with a rescue configuration by pressing the RESET CONFIG button. You
must have previously set the rescue configuration through the J-Web interface or the
CLI. The rescue configuration is a previously committed, valid configuration.
CAUTION: Pressing and holding the RESET CONFIG button for 15 seconds or
more—until the STATUS LED blinks red—deletes all configurations on the router,
including the backup configurations and rescue configuration, and loads and commits
the factory configuration.
You can change the default behavior of the RESET CONFIG button. For more
information, see the J-series Services Router Basic LAN and WAN Access ConfigurationGuide.
Built-In Gigabit Ethernet Ports
Four built-in Gigabit Ethernet ports provide LAN connections over copper interfaces
to hubs, switches, local servers, and workstations. You can also designate an Ethernet
port for management traffic. When configuring one of these ports, you use the
interface name that corresponds to the port’s location. From left to right on the front

The J6350 Services Router uses either AC or DC power. You can install one or two
autosensing, load-sharing power supplies on the system board at the bottom of the
chassis, as shown in Figure 15 on page 28 or Figure 17 on page 29. The power
supplies distribute the different output voltages to the router components, depending
on their voltage requirements. When two power supplies are installed and operational,
they automatically share the electrical load.
For full redundancy, two power supplies are required. If a power supply stops
functioning for any reason, the second power supply instantly begins providing all
the power the router needs for normal functioning. It can provide full power
indefinitely.
Each power supply has an LED located to the upper right of the power supply
connector. Table 16 on page 37 describes the power supply LED.
For information about site power preparations, see “Power Guidelines, Requirements,

The Routing Engine monitors the temperature of the router components. If the
maximum temperature specification, as measured at the CPU junction, is exceeded
and the router cannot be adequately cooled, the Routing Engine shuts down the
hardware components.
When the CPU temperature reaches 80°C (176°F), a yellow alarm is triggered. When
the CPU temperature reaches 105°C (221°F), the system shuts down. There is no
red alarm for temperature. You can view the CPU junction temperature using the
show chassis routing-engine command. The CPU temperature runs a few degrees
higher than the routing engine temperature displayed on the Monitor>Chassis page
of the J-Web interface.
NOTE: On J4350 and J6350 routers that are not designed to comply with Network
Equipment Building System (NEBS) criteria, the temperature at which the system
shuts down is 90°C (194°F) rather than 105°C (221°F). To verify that the system is
a NEBS-compliant system, run the show chassis hardware command. A
NEBS-compliant system displays the term NEBS in the output.
An additional fan is part of each power supply. This fan is not regulated by the

Chapter 2: System Overview
Software Overview
Each J-series Services Router runs the JUNOS Internet software on its general-purpose
processors. Designed for the large production networks typically supported by Internet
service providers (ISPs), the JUNOS software includes processes for Internet Protocol
(IP) routing and for managing interfaces, networks, and the router chassis.
The JUNOS Internet software runs on the Routing Engine. The Routing Engine kernel
coordinates communication among the JUNOS software processes and provides a
link to the Packet Forwarding Engine.
With the J-Web interface and the command-line interface (CLI) you configure the
routing protocols that run on the Services Router and set the properties of its network
interfaces. After activating a software configuration, use either user interface to
monitor the protocol traffic passing through the router, manage operations, and
diagnose protocol and network connectivity problems.
This section contains the following topics:

■JUNOS Software Processes on page 40
■User Interfaces on page 41
Software Overview■39
J2320, J2350, J4350, and J6350 Services Router Getting Started Guide
Routing Engine and Packet Forwarding Engine
A Services Router has two primary software processing components:
■Routing Engine—The Routing Engine provides three main functions:
■Creates the packet forwarding switch fabric for the Services Router, providing
route lookup, filtering, and switching on incoming data packets, then directing
outbound packets to the appropriate interface for transmission to the
network.
■Maintains the routing tables used by the router and controls the routing
protocols that run on the router.
■Provides control and monitoring functions for the router, including controlling
and other features; and forwards packets to the next hop along the route to their
final destination.
For information about Routing Engine hardware, see “J2320 and J2350 Routing
Engine Hardware” on page 18 and “J4350 and J6350 Routing Engine
Hardware” on page 31.
Kernel and Microkernel
The Routing Engine kernel provides the underlying infrastructure for all JUNOS
software processes by doing the following:
■Linking the routing tables maintained by the routing protocol process with the
forwarding table maintained by the Routing Engine
■Coordinating communication with the Packet Forwarding Engine, primarily by
synchronizing the Packet Forwarding Engine’s forwarding table with the master
forwarding table maintained by the Routing Engine
The microkernel contains device drivers and processes that the Packet Forwarding
Engine uses to govern the flow of packets through the Services Router.
JUNOS Software Processes
The JUNOS software running on the Routing Engine and Packet Forwarding Engine
consists of multiple processes that are responsible for individual Services Router
functions.
40■Software Overview
The separation of functions provides operational stability, because each process
accesses its own protected memory space. In addition, because each process is a
separate software package, you can selectively upgrade all or part of the JUNOS
software, for added flexibility.

User Interfaces
Responsible for most of the packet transmission through a Services Router. The overall
performance of the router is largely determined by the effectiveness of the forwarding
process.
The user interfaces on a Services Router interact with the management process to
execute commands and store and retrieve information from the configuration
database. The user interfaces operate as clients that communicate with the JUNOS
Internet software through an application programming interface (API).
The following primary user interfaces are shipped with the router:
■J-Web graphical user interface—Includes quick configuration capabilities for
performing the minimum required steps to enable a feature, plus a built-in
configuration editor with access to the entire configuration hierarchy to fully
configure the router. The J-Web interface also provides tools for monitoring,
managing, and diagnosing router operation.
■Command-line interface (CLI)—Grants access to the complete JUNOS command
and configuration hierarchies, to monitor the router, diagnose problems, and
configure it completely.

42■Software Overview
Chapter 3
PIM and VoIP Module Overview
J-series Services Routers accept Physical Interface Modules (PIMs) and Avaya VoIP
modules in the slots on the front of the chassis.
CAUTION: PIMs and VoIP modules are not hot-swappable. You must power off the
Services Router before removing or inserting a PIM or VoIP module. Ensure that the
PIMs and VoIP modules are installed in the router chassis before booting up the
system.
A Physical Interface Module (PIM) is a network interface card that is installed on a
J-series Services Router, to provide physical connections to a LAN or a WAN. The
PIM receives incoming packets from the network and transmits outgoing packets to
the network. Each PIM is equipped with a dedicated network processor that forwards
incoming data packets to the Routing Engine, and receives outgoing data packets
from the Routing Engine. During this process, the PIM performs framing and
line-speed signaling for its medium type.
For a complete list of supported PIMs, see “Field-Replaceable PIMs” on page 46.
Avaya VoIP modules are installed in the router chassis like PIMs, but are controlled
by the Avaya Communication Manager (CM) software rather than the JUNOS Internet
software. For a complete list of supported modules, see “Avaya VoIP
Modules” on page 67.

ITU-T Standard G.992.1 that defines how ADSL works over Integrated Services Digital
Network (ISDN) lines.
ISDN cost-control feature defining the bandwidth threshold that must be reached on
all links before a Services Router initiates additional ISDN data connections to provide
more bandwidth.
ISDN interface intended for home and small enterprise applications. BRI consists of
two 64-Kbps B-channels and one 16-Kbps D-channel.
Alternative feature to dial-in that enables a J-series Services Router to call back the
caller from the remote end of a backup ISDN connection. Instead of accepting a call
from the remote end of the connection, the router rejects the call, waits a configured
period of time, and calls a number configured on the router's dialer interface. See also
dial-in.
Telephone number of the caller on the remote end of a backup ISDN connection, used
to dial in and also to identify the caller. Multiple caller IDs can be configured on an
ISDN dialer interface. During dial-in, the router matches the incoming call's caller ID
against the caller IDs configured on its dialer interfaces. Each dialer interface accepts
calls from only callers whose caller IDs are configured on it.

A DTE cable uses a male 9-pin or 25-pin connector, and a DCE cable uses a female
9-pin or 25-pin connector.
Interface configured for dial-on-demand routing backup. In OSPF, the demand circuit
reduces the amount of OSPF traffic by removing all OSPF protocols when the routing
domain is in a steady state.
Feature that reestablishes network connectivity through one or more backup ISDN
dialer interfaces after a primary interface fails. When the primary interface is
reestablished, the ISDN interface is disconnected.
Feature that enables J-series Services Routers to receive calls from the remote end of
a backup ISDN connection. The remote end of the ISDN call might be a service provider,
a corporate central location, or a customer premises equipment (CPE) branch office.
All incoming calls can be verified against caller IDs configured on the router's dialer
interface. See also callback.

(DDR) backup
dialer watch
“dying gasp” notification
ePIM
Stateless firewall filter that enables dial-on-demand routing backup when applied to
a physical ISDN interface and its dialer interface configured as a passive static route.
The passive static route has a lower priority than dynamic routes. If all dynamic routes
to an address are lost from the routing table and the router receives a packet for that
address, the dialer interface initiates an ISDN backup connection and sends the packet
over it. See also dial-on-demand routing backup; floating static route.
Feature that provides a J-series Services Router with full-time connectivity across an
ISDN line. When routes on a primary serial T1, E1, T3, E3, Fast Ethernet, or PPPoE
interface are lost, an ISDN dialer interface establishes a backup connection. To save
connection time costs, the Services Router drops the ISDN connection after a configured
period of inactivity. Services Router with ISDN interfaces support two types of
dial-on-demand routing backup: on-demand routing with a dialer filter and dialer
watch. See also dialer filter; dialer watch.
Dial-on-demand routing (DDR) backup feature that provides reliable connectivity
without relying on a dialer filter to activate the ISDN interface. The ISDN dialer interface
monitors the existence of each route on a watch list. If all routes on the watch list are
lost from the routing table, dialer watch initiates the ISDN interface for failover
connectivity. See also dial-on-demand routing backup.
Ability of a Services Router with a digital subscriber line (DSL) connection that has lost
power to send a message informing the attached DSL access multiplexer (DSLAM)
that it is about to go offline.
Enhanced PIM. A particular type of high-speed PIM, such as the Gigabit Ethernet ePIM
or 4-port Fast Ethernet ePIM, which can be inserted only in high-speed slots (slots 3
and 6 on a J4350 Services Router, or slots 2, 3, 5, and 6 on a J6350 Services Router).

the dynamic routes are no longer available. When a floating static route is configured
on an interface with a dialer filter, the interface can be used for backup.
Interface between an ISDN network and a network termination device consisting of
two twisted pairs, one each for transmitting and receiving. The S/T interface usually
resides in the customer premises and operates at 192 Kbps, of which ISDN traffic
accounts for 144 Kbps.
Single twisted–pair interface line connecting the customer premises unit in an ISDN
network to the central office. A U interface runs at 144 Kbps (128 Kbps for two B
channels and 16 Kbps for the D channel).
Standard telephone service that allows limited speed and bandwidth of 52 Kbps, which
is also know as public switched telephone network (PSTN).
ISDN service intended for higher-bandwidth applications than ISDN BRI. ISDN PRI
consists of a single D-channel for control and signaling, plus a number of 64-Kbps
B-channels—either 23 B-channels on a T1 line or 30 B-channels on an E1 line—to
carry network traffic.
Universal switching PIM. A particular type of PIM, such as the Gigabit Ethernet uPIM,
which can be universally inserted in any slot on a J2320, J2350, J4350, or J6350
Services Router.

Field-Replaceable PIMs
PIMs are removable and insertable only when the Services Router is powered off.
You can install a PIM into one of the slots in the router chassis. If a slot is not occupied
by a PIM, a PIM blank panel must be installed to shield the empty slot and to allow
cooling air to circulate properly through the router.

Chapter 3: PIM and VoIP Module Overview
Features. Gigabit Ethernet uPIMs provide the following key features:
■The multiport uPIMs can be used as switches in the access layer (for connections
to workstations and desktops). For more information, see the J-series Services
Router Basic LAN and WAN Access Configuration Guide.
■Link speed for 8-port and 16-port Gigabit Ethernet uPIMs is configurable to 10,
100, or 1000 Mbps, and transmission mode is configurable to half or full duplex.
The 1-port and 6-port SFP Gigabit Ethernet uPIMs cannot be manually
configured—they are set at 1000 Mbps and full duplex.
■Autonegotiation.
■1-port and 6-port Gigabit Ethernet uPIMs use SFP transceivers to allow different
connectors to be used on uPIM ports. These SFP Gigabit Ethernet uPIMs support
1000Base-SX, 1000Base-LX, and 1000Base-T SFPs. They do not support
1000Base-LH SFPs.
1000Base-SX and 1000Base-LX SFP transceivers have the following characteristics:
■Duplex LC/PC connector (Rx and Tx).
■Optical interface support—See Table 22 on page 52.
■8-port and 16-port Gigabit Ethernet uPIMs—and SFPs on the 1-port and 6-port
uPIMs—support 1000Base-T RJ-45 connectors.
For pinouts of cable connectors for Gigabit Ethernet uPIMs, see “Gigabit Ethernet
uPIM RJ-45 Connector Pinout” on page 235.
Limitations. Gigabit Ethernet uPIMs have the following limitations:
■Gigabit Ethernet uPIMs do not support SNMP.
■Gigabit Ethernet uPIM interfaces can be configured up to a maximum MTU size
of 9014 bytes.
Installation. Gigabit Ethernet uPIMs can be inserted in any slot on J2320, J2350,
J4350, or J6350 Services Routers.
Throughput for a uPIM is higher when it is inserted in a high-speed slot. High-speed
slots are slots 3 and 6 on the J4350 router, and slots 2, 3, 5, and 6 on the J6350
router.
16-port Gigabit Ethernet uPIMs are two slots high. Because the connector on the PIM
is on the lower half, the PIM occupies the slot that it is plugged into and the slot above
it. Thus you cannot install a 16-port uPIM in the top slots of a router. For example,
on a J4350 router you cannot install a 16-port uPIM in slots 1 and 4. If you install
the PIM in slot 2, it occupies both slots 2 and 1.
To install or remove a PIM, see “Replacing a PIM” on page 174.
Interface LEDs. For 8-port and 16-port Gigabit Ethernet uPIMs, the activity LED is
located on the left side of each port, and the link LED is located on the right side of
each port. For the 6-port Gigabit Ethernet uPIM, the LEDs are located to the right of
each port, with the link LED above the activity LED. LEDs on the 1-port uPIM are
clearly labeled.Table 21 on page 52 describes the meaning of the LEDs.

For ISDN BRI trunking, the TIM521 supports up to four BRI interfaces to the central
office at the ISDN T reference point. Information is communicated on each port in
two ways:
Table 41: LEDs for TIM521
■Over two 64-Kbps B-channels, called B1 and B2, that can be circuit-switched
simultaneously
NOTE: The TIM521 does not support BRI stations or combining both B-channels
together to form a 128-Kbps channel.
■Over a 16-Kbps channel, called the D-channel, that is used for signaling. The
TIM521 occupies one time slot for all four D-channels
The circuit-switched connections have an a-law or mu-law option for voice operation.
The circuit-switched connections operate as 64-Kbps clear channels transmitting
data.
