Juniper Networks ERX-1410 - Manual (Page 22)

CHAPTER 1
ERX System Overview 1-2
All models use the same software. However, the specific model
determines:
• The combination of line modules supported
• The conditions for line rate performance of line modules
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.
