Introduction

1.1 LRS-24 Overview

Management/CM-2 Functions

LRS-24 is managed by a UNIX-based or PC-based SNMP management system via

the Central Management card (CM-2). The software is user-friendly, GUI-based

and runs under PC/Windows (RADview-PC) or HP OpenView (RADview-HPOV)

systems. Configuration and monitoring are also provided via Telnet or ASCII

terminal.

Network management provides centralized control of all LRS-24 hubs, modem

cards and remote modems in the network, including interface configuration,

connection setup, alarm and monitoring. A single management station can

control up to 64,000 LRS-24 hubs.

Direct 10BaseT Ethernet connection enables real-time management of central

and remote sites. Performance information is available in graph and table format

for the last 24 hours. This information can be saved in a file for accounting

purposes.

If a major alarm occurs, the LRS-24 CM-2 card can dial out through an external

dial-up modem to a central management site. This saves a direct connection to

remote sites, while providing alerts if critical events occur. In addition alarms can

activate dry contacts. The dry contacts are placed on the system clock connector

on CM-2.

Two types of modem cards are available on the LRS-24:

• S-Mode: Cards with a built-in SNMP agent

• I-Mode: Cards without an SNMP agent. For these cards CM-2 serves as the

SNMP proxy agent. The CM-2 built-in agent complies with SNMP MIB II and

supports generic SNMP HPOV applications.

A new software version can be downloaded from a remote site onto the CM-2

via:

• LAN by TFTP

• Terminal by XMODEM.

CM-2 saves up to three software versions.

When the management station includes BootP software, the CM-2 card

automatically retrieves the IP address required for management connection. This

eliminates the need to configure IP addresses for new hub installations.
