Overview
ERX routers are modular, carrier-class networking devices that deliver performance, reliability, and service differentiation to both business and consumer Internet users. The ERX7xx and ERX14xx models offer high port density, low power consumption, and fully redundant Internet access routing and edge aggregation. The Juniper Networks ERX310 Broadband Services Router supports the same services, but with smaller capacity and scaling capabilities. ERX routers offer the complete edge solution for IP-optimized carriers.
ERX Routers
Five models of ERX routers are available:
Juniper Networks ERX1440 Broadband Services Router
Juniper Networks ERX1410 Broadband Services Router
Juniper Networks ERX710 Broadband Services Router
Juniper Networks ERX705 Broadband Services Router
Juniper Networks ERX310 Broadband Services Router
All models use the same software. However, the specific model determines the:
Combination of line modules supported
Conditions for line rate performance of line modules
Type, capacity, and number of SRP modules used

ERX14xx Models
NOTE: In the E Series documentation, the term ERX14xx models refers to both the ERX1440 and ERX1410 routers. The terms ERX1440 and ERX1410 routers refer to the specific models. See Figure 1 on page 5 and Figure 2 on page 5.
The ERX1440 router manages an extremely high volume of network traffic, and uses a 40-Gbps switch route processor (SRP) module, either the SRP-40G or SRP-40G+ module.(The SRP-40G+moduleobsoletesthe SRP-40G module;however, thesoftware continues to support both modules.) In this model, all line modules operate at full wire speed simultaneously.
The ERX1410 router manages high levels of network traffic, and uses the 10-Gbps SRP module (SRP-10G). You can configure the ERX1410 router to enable the line modules either to operate at full line rate performance or to allow line modules to operate at a rate dependent on the resources available. The former option restricts the allowed combinationsof linemodules.For information on configuringperformanceof linemodules, see JunosE System Basics Configuration Guide, Chapter 6, Managing Modules.
NOTE: The 10-Gbps SRP module used in the ERX310 router is different from
the 10-Gbps SRP module used in the ERX1410 router. See “SRP Module” on page 9 for more information.
Externally, the ERX1440 chassis is the same as the ERX1410 chassis. (See Figure 1 on page 5 and Figure 2 on page 5.) Both routers contain 14 vertical slots to accommodate modules.
Internally, the ERX1440 chassis differs from the ERX1410 chassis, and includes a special midplane for the 40-Gbps SRP module.
Installation procedures and operating procedures are identical for both systems. All ERX7xx and ERX14xx models use the same SRP I/O module, but different power input modules are used.
NOTE: The router may look different from the routers shown in the figures
in this chapter, depending on the line modules in the slots.

ERX7xx Models
NOTE: In the E Series documentation,the term ERX7xx models refers to both the ERX705 and ERX710 routers.The terms ERX705 and ERX710 routers refer to the specific models. See Figure 3 on page 6 and Figure 4 on page 7.
The ERX7xx models are robust, high-density routers with less capacity than the ERX14xx models. The ERX7xx models use either the SRP-10G module or the SRP-5G module.
You can configure the ERX7xx models to enable the line modules (LM) to operate either at full line rate performance or at a rate dependent on the resources available. For information about configuring performance of line modules, see JunosE System Basics Configuration Guide, Chapter 6, Managing Modules.
NOTE: The 10-Gbps SRP module used in the ERX310 router is different from
the 10-Gbps SRP module used in the ERX710 router. See “SRP Module” on page 9 for more information.
The ERX705 chassis is the same as the ERX710 chassis. (See Figure 3 on page 6 and Figure 4 on page 7.) The chassis contains seven slots to accommodate modules. Installation procedures and operating procedures are identical for both systems. All ERX7xx and ERX14xx models use the same SRP I/O module, but different power input modules are used.
NOTE: The router may look different from the routers shown in the figures
in this chapter, depending on the line modules in the slots.

ERX310 Broadband Services Router
The ERX310 router is a low-end platform that supports all of the same services as the ERX7xx and ERX14xx models, but with smaller capacity and scaling capabilities. Like the ERX7xx and ERX14xx models, the ERX310 router uses the same software architecture, providing a single IP entry point into the network with the same IP-based protocols and services that are available on other ERX routers. The ERX310 router is designed to be used as a small distributed POP router as well as a high-end CPE router.
Chapter 1: ERX Overview
The ERX310 routeris athree-slot chassis witha midplane architecture.One slot supports one nonredundant10-Gbps SRPmodule, while the other twoslots support line modules. The router supportsexisting E Series ASIC-based line modules(except theOC48/STM16 line module), as well as a select number of combination cards. The combination cards provide a fixed combination of interfaces on the I/O module so that a single slot can support multiple interfaces (ATM OC3 and GE, for example).
NOTE: The 10-Gbps SRP module used in the ERX310 router is different from
the 10-Gbps SRP module used in the ERX7xx and ERX14xx models. See “SRP Module” on page 9 for more information.
The ERX310 router is available in either redundant AC- or DC-powered models.

ERX Modules
Chapter 1: ERX Overview
Each system supports an SRP module and a selection of line modules. You can use any line module for access or uplink. Access line modules receive traffic from low-speed circuits, and thesystem routes the traffic onto higher-speed uplinkline modules andthen to the core of the network.
Each module connects to a correspondingI/O module via a passive midplane. See Figure 8 on page 9.
The front panel of each module contains a collection of status LEDs (light-emitting diodes). For information about how to interpret the LEDs, see “Troubleshooting” on page 95.

SRP Module
Switch route processor (SRP) modules perform system management, routing table calculations and maintenance, forwarding table computations, statistics processing, configuration storage, and other control plane functions. Each SRP module is a

Module Details
ERX7xx and ERX14xx models use up to two redundant SRP modules operating in an active/standby configuration. ERX310 router use only one SRP module. An SRP module must be present for any system to boot.
SRP modules ranging from 5 Gbps to 40 Gbps can be used in ERX7xx and ERX14xx models. Only a 10-Gbps SRP module (SRP-SE10G) can be used in ERX310 router. See the ERX Module Guide for complete information.
NOTE: Because of different physical dimensions and switch fabric capabilities,
SRP modules are not interchangeable between systems. For example, the 10-Gbps SRP module used in ERX7xx and ERX14xx models cannot be used in the ERX310 router, and vice versa.
CAUTION: Do not remove the SRP module while the system is running.
NOTE: SomeSRP modules require a minimum amount of memory to be used
with JunosE Release5.3.0or a higher-numbered release. See the ERX Module Guide for module specifications.

For details about installing SRP modules, see “Installing Modules” on page 31.
SRP Module Redundancy
SRP module redundancy is available only for ERX7xx and ERX14xx models. See “Redundancy Features” on page 14
Nonvolatile Storage
The PCMCIA slot on the front of the SRP module holds a Type II PCMCIA nonvolatile storage (NVS) card. (See Figure 9 on page 10 and Figure 10 on page 11.) This card is loaded with the system's software and configuration files. The PCMCIA card is factory installed.
CAUTION: Although you can remove PCMCIA NVS (Flash) cards from a
running router, we recommend that you do not do so. If you remove the card while data is being written to or copied from the NVS card, data can be lost or corrupted. Therefore, we strongly recommend that you shut down the router before removing a PCMCIA NVS card.
SRP I/O Module
The SRP I/O module is a single corresponding input/output module that interfaces with the SRP modules through the system's midplane. The same SRP I/O module works with all SRP modules, but is router specific. The I/O module used in ERX7xx and ERX14xx models cannot be used in the ERX310 router, and vice versa. See Figure 2 on page 5, Figure 4 on page 7, and Figure 6 on page 8 for locations.
Module Details
The SRP I/O module provides standard craft management interfaces, including:
10/100Base-T—The port enables access to the ERX router for Ethernet management functions via CLI or SNMP, for example.
RS-232—The port provides a serial connection for monitoring the system's hardware configuration through a PC (running terminal emulation software) or ASCII terminal. Allows direct CLI access.
Alarm contacts—The contacts provide for remote indication of critical, major, and minor router alarms (ERX7xx and ERX14xx models only; currently not implemented)
External timing inputs—The inputs provide a method of ensuring that the clock timing used by the router remains synchronized with the network's system clock. BNC connectors and wire wraps are available for ERX7xx and ERX14xx models only.
For details about installing the SRP I/O module, see “Installing Modules” on page 31.
Line Modules
Line modules (LM) process data from different types of network connections. For information about available line modules and which SRP modules support specific line modules, see the ERX Module Guide.

Chapter 1: ERX Overview
Figure 11 on page 13 shows a representative line module. For details about installing line modules, see “Installing Modules” on page 31.
Figure 11: Representative Line Module
Packet Classification
Most linemodules support packetclassification on ingress;some non-ASICline modules do not. A classification engine on theline modulematches specific fields (such as source and destination IP address, source and destination port, and protocol), the ingress IP interface, layer 2 fields, or some combination of these against user-configured filters at wire speed.
I/O Modules
Most line modules have a corresponding input/output (I/O) module that provides the physical interconnection to the network. Insert each I/O module into the back of the system, directly behind its corresponding line module.
For information about which line modules pair with which I/O modules, see the ERX Module Guide. See Figure 2 on page 5, Figure 4 on page 7, and Figure 6 on page 8 for locations. For details about installing I/O modules, see “Installing Modules” on page 31.
Network Management Tools
You can use different management tools to configure the system to meet the specific networking requirements.

CLI Management
The CLI provides fully developed and automated configuration and status functionality through a localRS-232 port, Telnet, orSSH via any reachablenetwork. For a full discussion of the CLI, see JunosE System Basics Configuration Guide, Chapter 2, Command-Line Interface.
SNMP MIB Management
The system offers a complete SNMP interface for configuration, status, and alarm reporting. The system supports both Standard and Enterprise MIBs (Management Information Bases). The Juniper Networks E Series Enterprise MIB is ASN.1 notated for easy importing into third-party SNMP management applications. For more information, see JunosE System Basics Configuration Guide, Chapter 4, Configuring SNMP.
NMC-RX Device Management System
The NMC-RX application provides a global methodof managing allrouters,line modules, and ports through a graphical user interface.
Redundancy Features
This section describes system redundancy features.
SRP Modules
ERX7xx and ERX14xx models use a 1:1 redundancy scheme for the SRP module. When two SRP modules of the same type are installed in the chassis, one acts as a primary (active) and the second as a redundant (standby) module. Both SRP modules share a single SRP I/O module located in the rear of the chassis.
If the standby SRP module detects that the primary SRP module is not active (and high-availability mode is not enabled), it reboots the system and takes control. If high-availability mode has been enabled, automatic switchover occurs with near hitless failover. If you upgrade software, you must copy the software to the redundant SRP and reboot it. For information about configuring and managing SRP module redundancy, see JunosE System Basics Configuration Guide, Chapter 6, Managing Modules.
After you install two SRP modules, the modules negotiate for the primary role.A number of factors determine which module becomes the primary; however, preference is given to the module in the lower-numbered slot. The SRP modules record their latest roles and retain them the next time you switch on the system. For information about installing SRP modules, see “Installing Modules” on page 31.
NOTE: This section applies to ERX7xx and ERX14xx models only. ERX310
routers contain one SRP module and therefore do not offer SRP module redundancy.
