Chapter 4 Management via the CM-2 Module LRS-24 Installation and Operation Manual

4-2 Introduction

After performing the preliminary configuration, you can also manage the modules

installed in LRS-24 (equipped with the CM-2 module) using the following options:

• Manage all the modules installed in LRS-24 (including modules without

internal SNMP agents) by means of SNMP-based network management

stations. This is accomplished by connecting the station to the Ethernet port

located on the interface module serving the CM-2 module, LRSI-F1-CM2 or

LRSI-F2-CM2 through RS-232 using the SLIP Protocol. For example, you can

use the RADview network management station offered by RAD.

• Use the terminal as a supervision terminal under control of the software

installed in the CM-2 module, or in modules with supervision-terminal support

software.

• Manage via TELNET (terminal emulation).

1. If a key is not pressed for 10-15 minutes a message appears informing you that

you are disconnected from LRS-24. You must reconnect your terminal to

LRS-24.

2. Only one user can connect to LRS-24 at a time. If a second user tries to connect

to LRS-24 a message appears (see Chapter 5).

3. If Password Enable = YES and you do not press a key for 20 minutes a message

appears informing you that “You’re disconnected”. Press any key and the Password

Screen appears.

CM-2 Functions

CM-2 includes an advanced management module that enables using SNMP-based

network management stations to fully manage the equipment installed in LRS-24,

and monitor its status.

CM-2 performs the following functions:

• Identification of cards – automatically identifies the modules installed in the

LRS-24 hub and determines the internal management protocols supported by

each card. Basically, two types of protocols are used, one for managing

modules with internal SNMP agent, and another for managing modules

without agent.

• Initialization – automatically initializes the management parameters for each

module installed in LRS-24. This feature provides plug-and-play capabilities,

because the management system can always make contact and manage any

new module installed in LRS-24.

• Traps – remote connection involves an update in the management station’s

screen in order to receive Traps.

• Interface – provides the interface to SNMP-based network management

stations, and the interface required for using an ASCII terminal connected to

the CM-2 module as a supervision terminal.
