The terms ERX-705 router and ERX-710 router refer to the specific models. See Figure 3 and Figure 4. The ERX-7xx models are robust, high-density routers with less capacity than the ERX-14xx models.
ERX Overview The ERX-705 chassis is the same as the ERX-710 chassis. (See Figure 3 and Figure 4.) The chassis contains seven slots to accommodate modules. Installation procedures and operating procedures are identical for both systems. All ERX-7xx and ERX-14xx models use the same SRP I/O module, but different power input modules are used. NOTE: The router may look different from the routers shown in the figures in this chapter, depending on the line modules in the slots.
ERX 8.0.x Hardware Guide ERX-310 Router The ERX-310 router is a low-end platform that supports all of the same services as the ERX-7xx and ERX-14xx models, but with smaller capacity and scaling capabilities. Like the ERX-7xx and ERX-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 ERX routers.

ERX 8.0.x Hardware Guide 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 JUNOSe System Basics Configuration Guide, Chapter 2, Command-Line Interface.
ERX Overview 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. For information about installing SRP modules, see “Installing Modules” on page 35.
ERX 8.0.x Hardware Guide 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 can cover 3–6 slots. It provides additional connectivity that enables the spare line module to take control of the I/O module associated with any failed line module in the redundancy group. The spare I/O module provides connectivity from the spare line module to the redundancy midplane.

Chapter 3 Installing ERX Routers This chapter describes how to install ERX routers in a rack. It contains the following sections: Before You Begin on page 27 Freestanding Installation on page 27 Rack-Mounted Installation on page 28 The Next Step on page 33 Before You Begin Before installing E-series routers, be sure you: Have a plan for installing the routers that takes into consideration future expansion of your system. Have the tools and accessories needed to complete the installation.
ERX 8.0.x Hardware Guide WARNING: Two people are required to lift an E-series router. CAUTION: To prevent electrostatic damage to the system and its components, make sure persons handling the router wear an antistatic device. Connectors are located on the I/O modules and the power input module. These modules are installed from the rear of the router. (See Figure 14.) See “Cabling ERX Routers” on page 53 for cabling installation procedures.
Installing ERX Routers You can install an ERX-14xx model, an ERX-7xx model, and an ERX-310 router together in the same rack. (See Figure 15.) CAUTION: If you install an ERX-7xx model or ERX-310 router directly above an ERX-14xx model in the same rack, you must install a plenum between the ERX-7xx model or ERX-310 router and the ERX-14xx model so that the air can circulate between the systems. (See Figure 51.) This plenum is available from Juniper Networks.
ERX 8.0.x Hardware Guide Figure 15: ERX Routers Installed in Recommended Order Safety Guidelines Observe the following safety guidelines when mounting the router in a rack. WARNING: Install equipment in the rack from the bottom upward. This helps to maintain the stability of the rack and reduces the chance of the rack tipping over. WARNING: Three people are required to install the router in a rack: two to lift the system into position and one to screw it to the rack.
Installing ERX Routers CAUTION: Evaluate the overall loading of the branch circuit before you install any equipment into a rack. WARNING: Connect the router or rack to ground (earth), and ensure that a reliable grounding path is maintained in the rack. WARNING: Do not work on the system or connect or disconnect cables during lightning activity. WARNING: Be sure circuit breakers for the power source are in the OFF position before attaching power cables.
ERX 8.0.x Hardware Guide Preparing the Equipment Racks Following your installation plan, use a tape measure and marking pen to measure and mark space on each equipment rack for each router component. For horizontal spacing, follow Network Equipment Building System (NEBS) requirements. If you choose not to install a plenum, be sure to include 2 U of space between each chassis for proper exhaust. A plenum, however, is highly recommended.
Installing ERX Routers The Next Step After you finish installing the router: If you need to install any modules, see “Installing Modules” on page 35. If the router was delivered with the modules already installed, see “Cabling ERX Routers” on page 53 for instructions on connecting cables.

Chapter 9 Troubleshooting This chapter explains how you can troubleshoot a specific problem, such as abnormal LED activity or no system power, when you power up the router.
ERX 8.0.x Hardware Guide might fail if the module has not completed initialization. Use the show version command to display line module status. Do not enter commands for a line module until its state is listed as online. Troubleshooting Power Failures The system’s distributed power system is designed to consume low levels of power and dissipate low levels of heat. See “System Specifications” on page 119 for specifications of power consumption and heat dissipation.
Troubleshooting familiarize yourself with LED activity so that you can easily detect and correct a module-related problem with minimal or no system downtime. LED Identification The system’s modules have two sets of status LEDs. The top set indicates overall router and module status. The bottom set indicates module-specific status, such as port status (line modules) or fan status (SRP module). The number next to the port status LED on a line module corresponds to the number of the port on the I/O module.
