    E120 and E320 11.1.x Hardware Guide E120 Model A fully configured E120 router consists of 2 switch route processors (SRPs), 3 switch fabric modules (SFMs), 6 line modules, and up to 2 I/O adapters (IOAs) per line module. See Figure 3 on page 6 and Figure 4 on page 7. An IOA shelf (bracket) can be installed on a slot-by-slot basis to create a left and right IOA bay, enabling you to use up to two IOAs in the same slot.

  • Page 23: E120 And E320 Modules

    Chapter 1: E120 and E320 Overview Figure 4: E120 Router, Rear View E120 and E320 Modules The routers support SRP modules, SFM modules, line modules, and IOAs. You can use a 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 25: Nonvolatile Storage

    Chapter 1: E120 and E320 Overview NOTE: You cannot use SRP modules of different capacities in the same configuration. For example, you cannot install a SRP-100 module and a SRP-320 module in the same router. For details about installing SRP modules, see “Installing Modules” on page 27. Nonvolatile Storage Depending on the model, each SRP module has either two Type II PCMCIA nonvolatile storage (NVS) cards or two ATA flash cards (0, 1).

  • Page 27: Line Modules

    Chapter 1: E120 and E320 Overview NOTE: Hot-swapping an SRP IOA is unsupported during a unified in-service software upgrade (ISSU). If you have configured RADIUS server on an SRP IOA that you want to replace, you can perform either of the following actions to prevent loss of accounting or logout information: Disable accounting and, when there is no subscriber login or logout activity, hot-swap SRP IOA.

  • Page 28: Packet Classification

    E120 and E320 11.1.x Hardware Guide Figure 7: Representative Line Module Packet Classification The line module supports packet classification on ingress. 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.

    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 30: Redundancy Features

    E120 and E320 11.1.x Hardware Guide Redundancy Features This section describes system redundancy features. SRP Modules The router uses a 1:1 redundancy scheme for the SRP module. When two SRP modules are installed in the router, one acts as the primary (active) and the second as a redundant (standby) module.
  • Page 31 Chapter 1: E120 and E320 Overview The system monitors the temperature of each module. If the temperature of a module exceeds the maximum limit, the system immediately goes into thermal protection mode and the LMs and SFM modules are powered off. The system controllers remain active and respond on all management interfaces.

    Chapter 8: Maintaining the Router Upgrading a System That Contains One SRP Module If the system contains only one SRP module, you must power down the system before you upgrade the NVS card. CAUTION: If you do not use the halt command before removing or powering down an SRP module, the system's NVS card can become corrupted.

    E120 and E320 11.1.x Hardware Guide CAUTION: When handling modules, use an antistatic wrist strap connected to an ESD grounding jack. This action helps to protect the module from damage by electrostatic discharge. To upgrade the NVS cards on the SRP modules in a system that contains two SRP modules: Wear an antistatic wrist strap and connect it to one an ESD grounding jack on the router.
