I/O Modules
Most line modules have a corresponding input/output (I/O) module that provides
the physical interconnection to the network. Insert each I/O module into the back of
the system, directly behind its corresponding line module.
For information about which line modules pair with which I/O modules, see
Chapter 12, Module Specifications. See Figure 5, Figure 7, and Figure 9 for locations.
For details about installing I/O modules, see Chapter 5, Installing Modules.
Network Management Tools
You can use different management tools to configure the system to meet the
specific networking requirements.
CLI Management
The CLI provides fully developed and automated configuration and status
functionality through a local RS-232 port, Telnet, or SSH via any reachable network.
For a full discussion of the CLI, see the JUNOSe System Basics Configuration Guide,
Chapter 2, Command Line Interface.
SNMP MIB Management
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.
NMC-RX Device Management System
The NMX-RX application provides a global method of managing all routers, line
modules, and ports through a graphical user interface.
Redundancy Features
The system has the following redundancy features:
SRP Modules
ERX-7xx/14xx 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 and the second as a standby. Both SRP modules share a single SRP I/O
module located in the rear of the chassis.
NOTE: This section applies to ERX-7xx/14xx models only. ERX-310 routers contain
one SRP module and therefore do not offer SRP module redundancy.
