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 and Figure 2. |
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+ module obsoletes the SRP-40G module; however, the software 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 combinations of line modules. For information on configuring performance of line modules, see the Managing Modules chapter in the JunosE System Basics Configuration Guide.
| 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 for more information. |
Externally, the ERX1440 chassis is the same as the ERX1410 chassis. (See Figure 1 and Figure 2.) 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. |

Figure 2: ERX14xx Models, Rear View
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 and Figure 4. |
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 the Managing Modules chapter in the JunosE System Basics Configuration Guide.
| 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 for more information. |
The ERX705 chassis is the same as the ERX710 chassis. (See Figure 3 and Figure 4.) 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.
The ERX310 router is a three-slot chassis with a midplane architecture. One slot supports one nonredundant 10-Gbps SRP module, while the other two slots support line modules. The router supports existing E Series ASIC-based line modules (except the OC48/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 for more information. |
The ERX310 router is available in either redundant AC- or DC-powered models.
