Industry Canada Notice CS-03

The Industry Canada label identifies certified equipment. This certification means that the equipment meets certain telecommunications network protective, operation and safety requirements as prescribed in the appropriate Terminal Equipment Technical Requirements document(s). The Department does not guarantee the equipment will operate to the user's satisfaction. Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using and acceptable method of connection. The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations.

Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.

Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.

Notice: The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the maximum number of terminals allowed to be connected to a telephone interface. The termination on an interface may consist of any combination of devices subject only to the requirement that the sum of the Ringer Equivalence Numbers of all the devices does not exceed 5.

Avis CS-03 d’Industrie Canada

L’étiquette du ministère des Communications du Canada indique que l’appareillage est certifié, c’est-à-dire qu’il respecte certaines exigences de sécurité et de fonctionnement visant les réseaux de télécommunications. Le ministère ne garantit pas que l’appareillage fonctionnera à la satisfaction de l’utilisateur. Avant d’installer l’appareillage, s’assurer qu’il peut être branché aux installations du service de télécommunications local. L’appareillage doit aussi être raccordé selon des méthodes acceptées. Le client doit toutefois prendre note qu’une telle installation n’assure pas un service parfait en tout temps.

Les réparations de l’appareillage certifié devraient être confiées à un service d’entretien canadien désigné par lefournisseur. En cas de réparation ou de modification effectuées par l’utilisateur ou de mauvais fonctionnement del’appareillage, le service de télécommunications peut demander le débranchment de l’appareillage.

Pour leur propre sécurité, les utilisateurs devraient s’assurer que les mises à la terre des lignes de distribution d’électricité, des lignes téléphoniques et de la tuyauterie métallique interne sont raccordées ensemble. Cette mesure de sécurité est particulièrement importante en milieu rural.

Attention: Les utilisateurs ne doivent pas procéder à ces raccordements eux-mêmes mais doivent plutôt faire appel aux pouvoirs de réglementation en cause ou à un électricien, selon le cas.

Avis: Veuillez prendre note que pour tout appareillage supportant des lignes de type “loopstart,” l'indice d'équivalence de la sonnerie (IES) assigné à chaque dispositif terminal indique le nombre maximal de terminaux qui peuvent être raccordés à une interface. La terminaison d'une interface téléphonique peut consister en une combinaison de quelques dispositifs, à la seule condition que la somme d'indices d'équivalence de la sonnerie de tous les dispositifs n'excède pas 5. Le REN figure sur l’étiquette “FCC Rules Part 68” située sur le support du module ou à l’arrière de l’unité.

D.O.C. Explanatory Notes: Equipment Attachment Limitations

The Canadian Department of Communications label identifies certified equipment. This certification meets certain telecommunication network protective, operational and safety requirements. The department does not guarantee the equipment will operate to the users satisfaction.

Before installing the equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the company’s inside wiring associated with a single line individual service may be extended by means of a certified connector assembly (telephone extension cord). The customer should be aware that compliance with the above condition may not prevent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.

Caution: Users should not attempt to make such connections themselves, but should contact the appropriate electrical inspection authority, or electrician, as appropriate.

Notes explicatives du ministère des Communications: limites visant les accessoires

Avant d’installer l’appareillage, s’assurer qu’il peut être branché aux installations du service de télécommunications local. L’appareillage doit aussi être raccordé selon des méthodes acceptées. Dans certains cas, le câblage interne du service de télécommunications utilisé pour une ligne individuelle peut être allongé au moyen d’un connecteur certifié (prolongateur téléphonique). Le client doit toutefois prendre note qu’une telle installation n’assure pas un service parfait en tout temps.

Les réparations de l’appareillage certifié devraient être confiées à un service d’entretien canadien désigné par le fournisseur. En cas de réparation ou de modification effectuées par l’utilisateur ou de mauvais fonctionnement de l’appareillage, le service de télécommunications peut demander le débranchment de l’appareillage.

Attention: Les utilisateurs ne doivent pas procéder à ces raccordements eux-mêmes mais doivent plutôt faire appel aux pouvoirs de réglementation en cause ou à un électricien, selon le cas.

The systems offer high port density, low power consumption, and fully redundant Internet access routing and edge aggregation. The ERX edge routers offer the complete edge solution for IP-optimized carriers.

Four models of the ERX edge router are available:

• ERX-1440 system

• ERX-1410 system

• ERX-705 system

• ERX-700 system

CHAPTER 1

ERX System Overview

ERX-1400 Series

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

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 ERX-1440 system manages an extremely high volume of network traffic and uses a 40-Gbps switch route processor (SRP) module, either the SRP-40G or SRP-40G+ module. (The SRP-40G+ module obsoletes the SRP-40G module; however, the software continues to support both modules.) In this model, all line modules operate at full wire speed simultaneously.

The ERX-1410 system manages high levels of network traffic, and uses the 10-Gbps SRP module (SRP-10G). You can configure the ERX-1410 system to enable the line modules either to operate at full line rate performance or to allow line modules to operate at a rate dependent on the resources available. The former option restricts the allowed combinations of line modules. For information on configuring performance of line modules, see ERX System Basics Configuration

Guide, Chapter 5, Managing Line Modules and SRP Modules.

Externally, the ERX-1440 chassis is the same as the ERX-1410 chassis (see Figure 1-1 and Figure 1-2). Both systems contain fourteen vertical slots to accommodate modules and have the same power requirements. 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.

Internally, the ERX-1440 chassis differs from the ERX-1410 chassis, and includes a special midplane for the 40-Gbps SRP module.

In the ERX documentation, the term ERX-700 series refers to both the ERX-705 system and the ERX-700 system. The terms ERX-705 system and ERX-700 system refer to the specific models.

The ERX-705 system is a compact, high-performance model that manages low traffic density and uses a 5-Gbps SRP module, the SRP-5G+ module. The ERX-700 system is a robust, high-density system with less capacity than the ERX-1400 series. The ERX-700 system uses either the SRP-10G module or a 5-Gbps SRP module, the SRP-5G module. (Although the SRP-5G+ module obsoletes the SRP-5G module; the software continues to support both modules.)

You can configure the ERX-700 series to enable the line modules either to operate at full line rate performance or to operate at a rate dependent on the resources available. For information about configuring performance of line modules, see ERX System Basics Configuration

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.

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

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.

The front panel of each system module contains a collection of status LEDs (light-emitting diodes). See Figure 1-8. For information about how to interpret the LEDs, see Chapter 8, Troubleshooting.

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.

• The system processor board is the dedicated processor that boots the

system, manages diagnostics, and supports routing protocol processing.

An SRP module must be present for the system to boot. For details about installing SRP modules, see Chapter 3, Installing ERX Modules. For specifications of SRP modules, see Appendix B, Module Specifications.

Caution: Do not remove the SRP module while the system is running.

You can install two SRP modules of the same type in the system. If you do, the first SRP module serves as the primary; the second as a redundant module, which enhances the system’s reliability. See

Redundancy Features, later in this chapter.

Nonvolatile Storage

The PCMCIA slot on the front of the SRP module holds a Type II PCMCIA nonvolatile storage (NVS) card. This card retains the system’s configuration and software. See Figure 1-8. The PCMCIA card is factory installed.

SRP I/O Module

Figure 1-8 SRP 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. See Figure 1-2 and Figure 1-4.

The SRP module provides standard craft management interfaces, including:

• 10/100Base-T – a port for Ethernet management

• RS-232 – a port for VT100 management access

• External timing inputs – ports for external timing sources

For details about installing the SRP I/O module, see Chapter 3, Installing

ERX Modules.

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. 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.
