Introduction

This guide describes how to install and use the SuperStack ° II UPS
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.

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 our organization. Your computer system relies on the
battery backup of an Uninterruptible Power System (UPS) to
maintain network integrity when the main power source fails.

The SuperStack II UPS Management Module provides network
power management through UPS monitoring and control. The
Management Module is shipped with default settings that you can
change to meet the needs of your organization.

This chapter describes the SuperStack II UPS Management Module
and how to install the module in the SuperStack II UPS.

The SuperStack II UPS Management Module

The Management Module is a single box that connects to the
SuperStack II UPS directly through the management power
connector.

The Management Module is available in two different models:

Ethernet (3C16020) and Token Ring (3C16021). The Ethernet
model can connect to a twisted-pair Ethernet (10base-T) network
using an RJ-45 connector. With the Token-Ring model, you can
connect the Management Module to a shielded or unshielded
twisted-pair Token Ring at 4 Mbps or 16 Mbps.

The module contains a full SNMP agent that implements the
Internet standard (RFC-1628) UPS Management Information Base,
private extensions for more control, and relevant portions of MIB II.

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 données.
Seuls des âbles de données devraient y être connectés. Ne reliez
pas de prises téléphoniques à ces connecteurs.

Before You Start

You must have a SuperStack II UPS installed and operating to use
the Management Module, in addition to one of the following
cables:

Twisted-pair cable for an Ethernet network

■

The patch cable (STP or UTP) for your Token Ring network type

■

Installing the Management Module

To install the Management Module, you need access to the
management power connector on the UPS and the cables that are
connected to your network.
