ERX System Overview 1 This chapter provides information about the system. Topic Page The ERX System 1-1 Where the ERX System Fits In 1-6 ERX System Modules 1-7 Network Management Tools 1-11 Redundancy Features 1-11 The Next Step 1-15 The ERX System The ERX edge routers are modular, carrier-class networking devices that deliver performance, reliability, and service differentiation to both business and consumer Internet users.
1-2 CHAPTER 1 ERX System Overview All models use the same software. However, the specific model determines: • The combination of line modules supported • The conditions for line rate performance of line modules ERX-1400 Series In the ERX documentation, the term ERX-1400 series refers to both the ERX-1440 system and the ERX-1410 system. The terms ERX-1440 system and ERX-1410 system refer to the specific models.

The terms ERX-705 system and ERX-700 system refer to the specific models.
The ERX System ERX Edge Routers The ERX-705 chassis is the same as the ERX-700 chassis (see Figure 1-3 and Figure 1-4). The chassis contains seven slots to accommodate modules. Installation procedures and operating procedures are identical for both systems. All ERX systems use the same SRP I/O modules. Note: The system may look different from the systems shown in the figures in this chapter, depending on the line modules in the slots.
1-6 CHAPTER 1 ERX System Overview Where the ERX System Fits In Figure 1-5 and Figure 1-6 illustrate the position of the system as an edge router in an end-to-end Internet network. Communications with the system can take place over a variety of media. In Figure 1-5, the customers are businesses using T1/T3 communication lines. In Figure 1-6, the customers are using digital subscriber lines (DSLs) with a DSL access multiplexer (DSLAM).
ERX System Modules ERX Edge Routers ERX System Modules The 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 Internet. Each module connects to a corresponding I/O module via a passive midplane. See Figure 1-7.
1-8 CHAPTER 1 ERX System Overview SRP Module The SRP module (see Figure 1-8) is a two-board assembly; both boards connect to the system’s midplane and to each other: • The fabric board is a switch fabric server that queues packets for the line modules. The fabric server houses a flexible hardware queuing resource that empowers IP QoS for each physical and logical interface, providing weighted scheduling for preferential packet delivery.
ERX System Modules ERX Edge Routers Midplane connectors Fabric board Ejector Functional status LEDs Redundancy status LEDs Board reset button Nonmaskable interrupt (NMI) button PCMCIA NVS card Ejector System processor board Figure 1-8 SRP module SRP I/O Module A single corresponding input/output module called the SRP I/O module interfaces with one or two SRP modules through the system’s midplane. The same SRP I/O works with all models of the SRP module. This I/O module is two slots wide.
1-10 CHAPTER 1 ERX System Overview Line Modules Line modules process data from different types of network connections. For information about the available line modules and which SRP modules support specific line modules, see Appendix B, Module Specifications. Figure 1-9 shows a representative line module. For details about installing line modules, see Chapter 3, Installing ERX Modules. Packet Classification Each line module supports packet classification on ingress.
Network Management Tools ERX Edge Routers 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 in the back of the system, directly behind its corresponding line module. For information about which line modules pair with which I/O modules, see Appendix B, Module Specifications. For details about installing I/O modules, see Chapter 3, Installing ERX Modules.
1-12 CHAPTER 1 ERX System Overview SRP I/O module located in the rear of the chassis. If the primary SRP fails, the redundant SRP module assumes control without rebooting or initializing itself. (As a consequence, if you upgrade software, you must copy the software to the redundant SRP and reboot it.) For information about configuring and managing SRP module redundancy, see ERX System Basics Configuration Guide, Chapter 5, Managing Line Modules and SRP Modules.
Redundancy Features ERX Edge Routers If there is not enough space on the primary NVS card to create the synchronization reserve file, the synchronize command fails, and you see a warning message on the console. To resolve this issue, either delete unwanted files from the primary NVS card or replace the redundant NVS card with a higher-capacity NVS card. Line Modules The ERX system supports line module redundancy for several line modules.
1-14 CHAPTER 1 ERX System Overview Redundancy I/O module Primary I/O module 1 3 1 2 3 4 A packet arrives at the primary I/O module. The packet passes along the redundancy midplane from the primary I/O module to the redundancy I/O module. The packet passes from the redundancy I/O module to the spare line module. The spare line module processes the packet.
The Next Step ERX Edge Routers Fans Forced air-cooling keeps the temperature of the ERX modules and components within normal operating limits. In the ERX-1400 series, six cooling fans are located in a tray at the top of the system (see Figure 7-5). In the ERX-700 series, four cooling fans are located in a tray on one side of the system (see Figure 7-7). The system monitors the temperature of each module.

Accessing the ERX System 5 This chapter provides information on the various ways you can access the system to manage it. Managing your router includes both configuring and monitoring it. For basic information on the management of the system, see ERX System Basics Configuration Guide, Chapter 4, Managing the System.
5-2 CHAPTER 5 Accessing the ERX System For initial access to the system, you need to physically connect your console directly to the system’s RS-232 port. This connection allows you to use the CLI to set an IP address on the system. Once you configure the IP address, you can access the system remotely (for example, via Telnet). Console Port Setup You can connect a console (PC, Macintosh, or UNIX workstation) directly to the system via the RS-232 terminal port on the SRP I/O module.
Console Port Setup ERX Edge Routers Connecting Directly to the ERX System When you connect a console directly to the system, use a cable appropriate for your terminal connector. The cable must have a female DB-9 connector to attach to the RS-232 port on the system. To connect a console directly to the system: 1 Connect the female DB-9 connector to the RS-232 port on the system’s SRP I/O module. See Figure 5-1. 2 Connect the crossover adapter connector to your PC’s serial port.
5-4 CHAPTER 5 Accessing the ERX System address for the system. The system powers up in User Exec mode. To assign an IP address: 1 Enter the enable command at the User Exec prompt. host1>enable host1# The system is now in Privileged Exec mode. 2 Set an IP address on the Ethernet interface: • Substitute the slot number where the SRP module is located for the slotnumber variable. • Use an IP address valid for the system. host1#configure terminal Enter configuration commands, one per line. End with CNTL/Z.
Telnet Setup ERX Edge Routers The system is now in Privileged Exec mode. 2 Enter the configure command. host1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. host1(config)# The system is now in Global Configuration mode. 3 Enter the line command. host1(config)#line vty 0 4 host1(config-line)# The system is now in Line Configuration mode. 4 Disable the password.
5-6 CHAPTER 5 Accessing the ERX System Caution: Do not change the IP address for the Ethernet interface that you are using to communicate with the system. If you change the address, you will lose the Telnet session. SNMP The system supports Simple Network Management Protocol (SNMP), a standard management protocol for IP networks. You can configure the system as an SNMP agent. As an SNMP agent, the system provides access to management information that it maintains.
Powering Up the System 6 This chapter provides instructions for powering up the system and information on electrical specifications. Topic Page Before You Power Up the System 6-1 Powering Up 6-2 Status LEDs 6-3 Powering Down 6-3 The Next Step 6-4 Before You Power Up the System Before powering up the system, you should complete the tasks shown in Table 6-1.

Resetting Line Modules and SRP Modules ERX Edge Routers Resetting Line Modules and SRP Modules Two recessed buttons on line modules and SRP modules provide the mechanisms for resetting. You can use the NMI button to reset the software on the module and the board reset button to reset the module. See Figure 1-8 and Figure 1-9. If a line module fails to respond for an extended period of time, there may be a software problem with that module.
8-12 CHAPTER 8 Troubleshooting If ECC detects a double-bit error in a system that contains a redundant SRP module, the redundant module becomes active and the system continues to operate. However, you must still troubleshoot the SRP module with the double-bit error. If ECC detects a double-bit error in a system that does not contain a redundant SRP module, you must troubleshoot the SRP module immediately. See Fixing Double-Bit Errors.

Installing ERX System Software E Caution: Check the Release Notes for extra information about installing and upgrading the software. This appendix provides information on how to install new software on the Juniper Networks ERX systems.
E-2 APPENDIX E Installing ERX System Software example, if the release number is x.y.z, the name of the directory is x-y-z. To identify the software release file: 1 Access the software directory. 2 Find the files with the extension .rel. • The software release file for the ERX-1440 system has the format erx40_x-y-z.rel, where x.y.z is the release number. • The software release file for all other ERX systems has the format erx_x-y-z.rel, where x.y.z is the release number.
Installing Software When a Firewall Exists ERX Edge Routers 9 Install the software release file to the system space on the ERX system. 10 Save the current configuration. 11 Reboot the system.
E-4 APPENDIX E Installing ERX System Software 4 Set an IP address on the interface. host1#configure Configuring from terminal or file [terminal]? Enter configuration commands, one per line. End with CNTL/Z. host1(config)#interface fastEthernet 6/0 host1(config-if)#ip address ipAddress [ mask ] 5 Press , to return to Privileged Exec mode.
Installing Software When a Firewall Exists ERX Edge Routers If the network host is listed, go to step 8. Otherwise, proceed with step 6. 6 Add an entry to the Static Host Table so that the ERX system can access the network host. The host command allows you to specify the network host name and IP address. host1#configure Configuring from terminal or file [terminal]? Enter configuration commands, one per line. End with CNTL/Z.
E-6 APPENDIX E Installing ERX System Software directory. If you specify a subdirectory that does not exist, the ERX system creates the directory. Note: Be sure to transfer the software release file and all the files it lists. Task 9: Install Files on the System Space Installing the software release file to the system space installs all files listed in the software release file.
Installing Software When a Firewall Does Not Exist ERX Edge Routers 3 Press to return to Privileged Exec mode. 4 Check that the ERX system is ready to boot with the new software release. host1#show boot If the old software version is still listed, verify that you completed the previous steps correctly. 5 Run the reload command. host1#reload The following message appears when you execute this command: WARNING: Execution of this command will cause the system to reboot.
E-8 APPENDIX E Installing ERX System Software To install the software, perform the following tasks: 1 Obtain the required information for the installation. 2 Access the Privileged Exec CLI command mode. 3 Configure IP on an interface. 4 Configure access to the network host. 5 Mount the CD on the network host. 6 Copy the software release file to the ERX system. 7 Save the current configuration. 8 Reboot the system.
Installing Software When a Firewall Does Not Exist ERX Edge Routers 2 Determine the port number of the module. 3 Determine whether the interface already has an IP address. host1#show ip interface fastEthernet 6/0 Note: If an IP interface is not configured, you see the message: “Invalid interface.” If the interface already has an IP address, go to step 5. Otherwise, proceed with step 4. 4 Set an IP address on the interface.
E-10 APPENDIX E Installing ERX System Software If the network host is listed, go to step 8. Otherwise, proceed with step 6. 6 Add an entry to the Static Host Table so that the ERX system can access the network host.
