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

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).

Notes 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.
