    Chapter 1: ERX Overview ERX Modules Each system supports an SRP module and a selection of line modules. You can use any line module for access or uplink. Access line modules receive traffic from low-speed circuits, and the system routes the traffic onto higher-speed uplink line modules and then to the core of the network.

  • Page 27: Module Details

    Chapter 1: ERX Overview Figure 10: SRP Module for ERX310 Router Module Details ERX7xx and ERX14xx models use up to two redundant SRP modules operating in an active/standby configuration. ERX310 router use only one SRP module. An SRP module must be present for any system to boot. SRP modules ranging from 5 Gbps to 40 Gbps can be used in ERX7xx and ERX14xx models.

  • Page 28: Srp Module Redundancy

    ERX 11.1.x Hardware Guide NOTE: Some SRP modules require a minimum amount of memory to be used with JUNOSe Release 5.3.0 or a higher-numbered release. See the ERX Module Guide for module specifications. For details about installing SRP modules, see “Installing Modules” on page 31. SRP Module Redundancy SRP module redundancy is available only for ERX7xx and ERX14xx models.

Line Modules Line modules (LM) process data from different types of network connections. For information about available line modules and which SRP modules support specific line modules, see the ERX Module Guide.

  • Page 30: I/O Modules

    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 4, Configuring SNMP.

  • Page 31: Nvs Cards

    Chapter 1: ERX Overview ERX7xx and ERX14xx models use a 1:1 redundancy scheme for the SRP module. When two SRP modules of the same type are installed in the chassis, one acts as a primary (active) and the second as a redundant (standby) module. Both SRP modules share a single SRP I/O module located in the rear of the chassis.

  • Page 32: Line Modules

    ERX 11.1.x Hardware Guide Line Modules NOTE: This section applies to ERX7xx and ERX14xx models only. ERX310 routers do not offer line module redundancy.
