Regulatory Compliance Statement s

Industry Canada Compliance Statement

This digital apparatus does not exceed the Class A limits for radio noise emiss ions from digital apparatus set out in the Radio Interference Regulations of the Canadian Department of Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de la class A prescrites dans le Règlement sur le brouillage radioélectrique édicté par le ministère des Communications du Canada.

NOTICE: The Industry Canada label identifies certified equipment. This certification means that the equipment meets telecommunications network protective, operational, 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 con nected to the facilities of the local telecommunications company. The equipment must also be installed using an 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 appr opriate 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 c onnected 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.

VCCI Compliance Statement

This is a Class A product based on the standard of the Voluntary Control Council for Interference by Information Technology Equipment (VCCI). If this equipment is used in a domestic environment, radio disturbance may arise. When such trouble occurs, the user may be required to take corrective actions.

Safety Information: Class 1 Laser Transceivers

This product may use Class 1 laser transceivers. Read the following safety information before installing or operating this product.

The Class 1 laser transceivers use an optical feedback loop to maintain Class 1 operation limits. This control loop eliminates the need for maintenance checks or adjustments. The output is factory set and does not allow any user adjustment. Class 1 laser transceivers comply with the following safety standards:

• 21 CFR 1040.10 and 1040.11, U.S. Department of Health and Human Services (FDA)

• IEC Publication 825 (International Electrotechnical Commission)

• CENELEC EN 60825 (European Committee for Electrotechnical Standardization)

When operating within their performance limitations, laser transceiver output meets the Class 1 accessible emission limit of all three standards. Class 1 levels of laser radiation are not considered hazardous.

Laser Radiation and Connectors

When the connector is in place, all laser radiation remains within the fiber. The maximum amount of radiant power exiting the fiber (under normal conditions) is –12.6 dBm or 55 x 10

Removing the optical connector from the transceiver allows laser radiation to emit directly from the optical port. The maximum radiance from the optical port (under worst case conditions) is 0.8 W cm or 8 x 10

Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases eye hazard. When viewing the output optical port, power must be removed from the network adapter.

2 SmartSwitch Router User Reference Manual

This chapter provides information that you need to know before configuring the SmartSwitch Router (SSR). If you have not yet installed the SSR, use the instructions in the SmartSwitch Router Getting Started Guide to install the chassis an d perform basic setup tasks, then return to this manual for more detailed configuration information.

Configuration Files

The SmartSwitch Router Getting Started Guide introduced the following configuration files used by the SSR:

• Startup – The configuration file that the SSR uses to configure itself when the system

is powered on. The Startup configuration remains even when the system is rebooted.

Chapter 1

Introduction

• Active – The commands from the Startup configuration file and any configuration

commands that you have made active from the scratchpad. The active configuration remains in effect until you power down or reboot the system.

• Scratchpad – The configuration commands you have entered during a CLI session.

These commands are temporary and do not become active until you explicitly make them part of the active configuration.

Note:

Entering commands and saving configuration files are discussed in more detail in the following section.

SmartSwitch Router User Reference Manual 3

Because some commands depend on other commands for successful execution, the SSR scratchpad simplifies system configuration by allowing you to enter configuration commands in any order, even when dependencies exist. When you activate the commands in the scratchpad, the SSR sorts out the dependencies and executes the command in the proper sequence.

Chapter 1: Introduction

Using the Command Line Interface

Note:

The CLI allows you to enter and execute commands from the SSR Console or from Telnet sessions. Up to four simultaneous Telnet sessions are allowed. CLI commands are grouped by subsystems. For example, the set of commands that let you configure and display IP routing table information all start with ip. Within the set of ip commands are commands such as set, show, start, stop, configure, etc. The complete set of commands for each subsystem is described in the SmartSwitch Router Command Line Interface Reference Manual.

The SSR provides both a graphical user interface (CoreWatch) and a command line interface (CLI) to configure and manage the SSR. In this manual, example configurations show how to use the CLI comman d s to configure the SSR. Using CoreWatch is described in the CoreWatch User’s Manual.

Command Modes

The CLI provides access to four different command modes. Each command mode provides a group of related commands. This section describes how to access and list the commands available in each command mode and explains the primary uses for each command mode.

User Mode

Enable Mode

After you log in to the SSR, you are automatically in User mode. The User commands available are a subset of those available in Enable mode. In general, the User commands allow you to display basic inform ation and use basic utilities such as ping.

The User mode command prompt consists of the SSR name followed by the angle bracket (>), as shown below:

ssr>

The default name is SSR unless it has been changed during initial configuration. Refer to the SmartSwitch Router Getting Started Guide for the procedures for changing the system name.

Enable mode provides more facilities than User mode. You can display critical features within Enable mode including router configuration, access control lists, and SNMP statistics. To enter Enable mode from the User mode, enter the command enable (or en), then supply the password when prompted.
