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 protocol
• 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.
LRS-24 can also be managed from an ASCII terminal. It allows all functions of
SNMP except for GUI interface. The connection is made via a V.24 supervisory
port using SLIP or PPP protocol.
Telnet support enables terminal connection over any IP network.
The CM-2 panel includes an alphanumeric display with two characters used for
alerting on fault conditions and for the hub IP address.
