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.

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.
