ABOUT THIS GUIDE

Introduction

This guide describes how to install and use the SuperStack®II

Advanced RPS Management Module.

Each procedure is outlined in a series of steps. These procedures

are written primarily for network supervisors who are responsible

for installing and configuring the Management Module. You should

also be familiar with PC hardware and software, and have a basic

understanding of your network. Your network should be set up

and operating properly.

vi ABOUT THIS GUIDE

Convention Description

“Enter” vs. “Type” When the word “enter” is used in this guide, it means

to type something, then press the [Return] or [Enter] key.

Do not press the [Return] or [Enter] key when the

instruction simply says “type”.

Text represents as

screeen display This typeface is used to represent displays that appear on

your screen, for example:

Enter the IP address:

Text represents as

commands This typeface is used to represent commands that you

enter, for example:

IP 191.0.0.172

Keys When specific keys are referred to in the text, they are

shown as [Enter] or [Return].

Italics Italics are used to denote new terms or emphasis.

Angle brackets These give a description (either general or specific) of

something that you should type in as part of a

command, for example <string> means type in some

string of letters.

They can also be used to give a general description of

something liable to change, and so not stated explicitly

in this manual for example <software version>.

1INTRODUCTION

In the modern business environment, communication and sharing

information is crucial. With computer networks becoming larger

and more complex, a constant power supply is vital to the

operation of your organization. A Redundant Power Supply (RPS)

provides a highly reliable resilient power supply to maintain

network integrity.

The SuperStack®II Advanced RPS Management Module provides

network management of the Advanced RPS through monitoring

and control. The Management Module is shipped with default

settings that you can change to meet the needs of your

organization.

Networking Terminology

A Network is a collection of workstations (for example

IBM-compatible personal computers) and other equipment (for

example, printers), connected for the purpose of exchanging

information. Networks vary in size. Some are within a single room,

others span continents.

Ethernet is a type of local area network, referring to the

technology used to pass information around the network.

10BASE-T is the name given to the Ethernet protocol that runs

over Unshielded Twisted-Pair (UTP) cable. The Management

Module uses an RJ-45 connector for connecting your network.

1-2 CHAPTER 1: INTRODUCTION

Simple Network Management Protocol (SNMP) is a protocol

that controls how a management station gains information from a

device. SNMP is composed of three areas:

■A set of rules that define how a management station can

communicate with a device.

■A Management Information Base (MIB) that defines what

information can be obtained from the device by the

management station. Every SNMP-manageable device has a

MIB.

■Unsolicited messages called Traps, which work differently to the

usual request/reply management communication. You can

configure a device so that it generates a Trap if a certain

condition occurs; for example, a power overload. The Trap will

be sent to the management station to inform it of the

occurrence.

Device is a term that is used to refer to a piece of network

equipment. Every device has a unique address that is used to

identify it on the network.

Internet Protocol (IP) is a data communication protocol used to

connect computers and data equipment into computer networks. It

is used on a large international network called the Internet, which

is composed of universities, government facilities, research

institutions, and private companies.

Serial Line Internet Protocol (SLIP) is the protocol for routing IP

data down a serial line.

2INSTALLATION

This chapter describes the SuperStack®II Advanced RPS

Management Module and how to install the module in the

SuperStack II Advanced RPS.

The SuperStack II Advanced RPS Management Module

The Management Module plugs directly into your SuperStack II

Advanced RPS chassis.

The Management Module connects to an Ethernet network with a

10BASE-T cable having an RJ-45 connector.

The module contains a full SNMP agent that implements the

relevant portions of MIB II and private extensions for more control.

New versions of the agent may be loaded onto the module as they

become available.

WARNING: The RJ-45 connector is a data socket. Only data cables

should be connected to it. Do not connect telephone outlets to

these connectors.

AVERTISSEMENT: Le connecteur RJ-45 est une prise de donnèes.

Seuls des câbles de dennèes devraient y être connectès. Ne reliez

pas de prises tèlèphoniques à ces connecteurs.

WARNUNG: Bei dem Anschluß RJ-45 handelt es sich um eine

Datenbuchse, an die ausschließlich Datenleitungen angeschlossen

werden dürfen. Schließen Sie keine Telefonanschlüsse an diese

Buchsen an.
