E-series Overview Figure 5: ERX-14xx Model, Rear View Fan tray module SRP I/O module Power input module Cable management bracket Plenum 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.
Page 24 ERX 7.0.x Hardware Guide The ERX-705 chassis is the same as the ERX-710 chassis (see Figure 6 and Figure 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.
Page 25: Erx-310 Router
E-series Overview 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.

E-series Overview Figure 13: ERX-310 SRP Module Ejector Midplane connectors Status LEDs PCMCIA NVS card Board reset button Integrated fabric system processor board NMI button Module Details ERX-7xx/14xx models use up to two redundant SRP modules operating in an active/standby configuration. ERX-310 routers use only one SRP module. An SRP module must be present for any system to boot.
Page 30: Srp Module Redundancy
If you remove the card while data is being written to or copied from the NVS card, data may be lost or corrupted. Therefore, Juniper Networks strongly recommends that you shut down the router before removing a PCMCIA NVS card.
Page 31: Module Details
E-series Overview Module Details The SRP module provides standard craft management interfaces, including: 10/100Base-T—Enables access to the E-series router for Ethernet management functions via CLI or SNMP, for example. RS-232—Provides a serial connection for monitoring the system’s hardware configuration through a PC (running terminal emulation software) or ASCII terminal.
Page 32: Packet Classification
ERX 7.0.x Hardware Guide Figure 14: Representative Line Module Ejector Status LEDs Midplane connectors Board reset button NMI button Packet Classification Most line modules support packet classification on ingress (some non-ASIC line modules do not). A classification engine on the line module matches 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.
Page 33: Network Management Tools
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 3, Configuring SNMP.
Page 34: Nvs Cards
ERX 7.0.x Hardware Guide 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.
Page 35 E-series Overview Guide. In this scheme, an extra line module in a group of identical line modules provides redundancy in case of line module failure. To use this feature, you need a: Spare line module Redundancy midplane Redundancy I/O module A redundancy midplane may cover 3–6 slots.
