The ERX System

The ERX edge routers are modular, carrier-class networking devices that deliver performance, reliability, and service differentiation to both business and consumer Internet users. The systems offer high port density, low power consumption, and fully redundant Internet access routing and edge aggregation. The ERX edge routers offer the complete edge solution for IP-optimized carriers.

Four models of the ERX edge router are available:

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

ERX-1400 Series

In the ERX documentation, the term ERX-1400 series refers to both the ERX-1440 system and the ERX-1410 system. The terms ERX-1440 system and ERX-1410 system refer to the specific models.

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

Externally, the ERX-1440 chassis is the same as the ERX-1410 chassis (see Figure 1-1 and Figure 1-2). Both systems contain fourteen vertical slots to accommodate modules and have the same power requirements. Installation procedures and operating procedures are identical for both systems. All ERX systems use the same SRP I/O modules.



Note: The system may look different from the systems shown in the figures in this chapter, depending on the line modules in the slots.

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

ERX-700 Series

In the ERX documentation, the term ERX-700 series refers to both the ERX-705 system and the ERX-700 system. The terms ERX-705 system and ERX-700 system refer to the specific models.

The ERX-705 system is a compact, high-performance model that manages low traffic density and uses a 5-Gbps SRP module, the SRP-5G+ module. The ERX-700 system is a robust, high-density system with less capacity than the ERX-1400 series. The ERX-700 system uses either the SRP-10G module or a 5-Gbps SRP module, the SRP-5G module. (Although the SRP-5G+ module obsoletes the SRP-5G module; the software continues to support both modules.)

You can configure the ERX-700 series to enable the line modules either to operate at full line rate performance or to operate at a rate dependent on the resources available. For information about configuring performance of line modules, see ERX System Basics Configuration Guide, Chapter 5, Managing Line Modules and SRP Modules.

The ERX-705 chassis is the same as the ERX-700 chassis (see Figure 1-3 and Figure 1-4). The chassis contains seven slots to accommodate modules. Installation procedures and operating procedures are identical for both systems. All ERX systems use the same SRP I/O modules.



Note: The system may look different from the systems shown in the figures in this chapter, depending on the line modules in the slots.
