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.

DUA1608-0AAA01
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.

Before You Start 2-3
Before You Start
The SuperStack II Advanced RPS Management Module will only
operate with the SuperStack II Advanced RPS. You will need a
10BASE-T cable for connection to your Ethernet network and a
serial cable to configure your Management Module. You may also
use the serial cable and for management via a modem, if required.
Installing the Management Module
To install the Management Module, you need access to the cables
that are connected to your network.
WARNING: Ensure that the Advanced RPS is disconnected from
the mains. Both power cables must be removed.
AVERTISSEMENT: S’assurer que le système Préliminaire RPS est
déconnecté du secteur d’alimentation. Les deux câbles doivent
être retirés.
WARNUNG: Versichern Sie sich, daß das Advanced RPS von Netz
getrennt ist. Beide Netzstecker müssen entfernt werden.
1Remove the blanking plate on the SuperStack II Advanced RPS rear
panel. Retain the blanking plate and screws for re-use if the
Management Module is removed. The plate is important to the
flow of cooling air to the unit.

3CONFIGURING THE
MANAGEMENT MODULE
You need to configure the SuperStack®II Advanced RPS
Management Module before you can use it. The Management
Module has a Command Line Interface (CLI) that you can access by
connecting the module to a terminal or a computer with a terminal
emulation program directly or via a modem.
The CLI provides initial configuration of the Management Module.
To manage the Superstack II Advanced RPS, you can use 3Com
Transcend or another SNMP network manager.
Before You Start
If your network has a BootP server configured to respond, the
Management Module will solicit its addresses automatically.
Otherwise, make sure you ask your network administrator to
supply the following values. Space is provided for you to record
these values for future reference.
IP address:........................................................................................
Subnet mask:....................................................................................
Default Router:..................................................................................
SLIP address:.....................................................................................
SLIP mask:.........................................................................................

DUA1608-0AAA01
3-2 CHAPTER 3: CONFIGURING THE MANAGEMENT MODULE
You will only need to configure the addresses of the module if
there is no configured BootP server on your network. To use the
configuration program for the Management Module, you need:
■A serial cable (see Table A-2 in Appendix A).
■A terminal with an RS-232 serial port, or a PC with a terminal
emulation program such as Windows Terminal®.
The host serial port should be set to 9600 baud, no parity, 8 bits,
and 1 stop bit. The console port always runs at these settings.
Local Configuration
To connect the module to the terminal and start the configuration
program:
1Plug the serial cable into the module console port.
2Plug the other end of the serial cable into the serial port on the
back of the terminal.
3Press [Return]. The following login prompt should appear (see
System Login on page 3-4 for more details).

Local Configuration 3-3
If you still do not see the login prompt, check the following
conditions:
■Check the communications settings of the terminal you are
using. It should be set to 9600 baud, no parity, 8 bits, and 1
stop bit.
■If the serial configuration is correct, check the cable between
the module and terminal to be sure all connections are secure.
■Make sure your terminal program is on the correct
communications port for your RS-232 connection.
