E-Series Routers

Five models of E-series routers are available:

All models use the same software. However, the specific model determines the:

ERX-14xx Models



Note: In the E-series documentation, the term ERX-14xx models refers to both the ERX-1440 router and the ERX-1410 router. The terms ERX-1440 router and ERX-1410 router refer to the specific models. See Figure 1-4 and Figure 1-5.

The ERX-1440 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 ERX-1410 router manages high levels of network traffic, and uses the 10-Gbps SRP module (SRP-10G). You can configure the ERX-1410 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 E-Series System Basics Configuration Guide, Chapter 5, Managing Line Modules and SRP Modules.



Note: The 10-Gbps SRP module used in the ERX-310 router is different from the 10-Gbps SRP module used in the ERX-1410 router. See section SRP Module, later in this chapter, for more information.

Externally, the ERX-1440 chassis is the same as the ERX-1410 chassis (see Figure 1-4 and Figure 1-5). Both routers contain 14 vertical slots to accommodate modules.

Internally, the ERX-1440 chassis differs from the ERX-1410 chassis, and includes a special midplane for the 40-Gbps SRP module.

Installation procedures and operating procedures are identical for both systems. All ERX-7xx/14xx 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.

ERX-7xx Models



Note: In the E-series documentation, the term ERX-7xx models refers to both the ERX-705 router and the ERX-710 router. The terms ERX-705 router and ERX-710 router refer to the specific models. See Figure 1-6 and Figure 1-7.

The ERX-7xx models are robust, high-density routers with less capacity than the ERX-14xx models. The ERX-7xx models use either the SRP-10G module or the SRP-5G module.

You can configure the ERX-7xx models to enable the line modules 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 E-Series System Basics Configuration Guide, Chapter 5, Managing Line Modules and SRP Modules.



Note: The 10-Gbps SRP module used in the ERX-310 router is different from the 10-Gbps SRP module used in the ERX-710 router. See section SRP Module, later in this chapter, for more information.

The ERX-705 chassis is the same as the ERX-710 chassis (see Figure 1-6 and Figure 1-7). The chassis contains seven slots to accommodate modules. Installation procedures and operating procedures are identical for both systems. All ERX-7xx/14xx 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.

ERX-310 Router

The ERX-310 router is a low-end platform that supports all of the same services as the ERX-7xx/14xx models, but with smaller capacity and scaling capabilities. Like the ERX-7xx/14xx models, the ERX-310 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 E-series routers. The ERX-310 router is designed to be used as a small distributed POP router as well as a high-end CPE router.

The ERX-310 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).



Note: The 10-Gbps SRP module used in the ERX-310 router is different from the 10-Gbps SRP module used in the ERX-7xx/14xx models. See section SRP Module, later in this chapter, for more information.

The ERX-310 router is available in either redundant AC- or DC-powered models.
