LRS-24 Installation and Operation Manual Chapter 4 Management via the CM-2 Module
Introduction 4-5
Preliminary Configuration of CM-2 module
• Configuration of the terminal type supported by its supervisory port.
• Configuration of its SNMP agent parameters. This function is needed to
establish communication with SNMP-based management stations, and to
designate the management stations authorized to manage LRS-24.
The configuration activities are a prerequisite for performing other activities. They
must be performed whenever a new CM-2 module is installed in an LRS-24
system.
Preliminary Configuration of Other Modules.
• Preliminary configuration required by I/O modules is described in their
Installation and Operation Manuals. A complete set of preliminary
configuration activities, which are actually required only for modules with
internal SNMP agent, must also include configuration of I/O module
supervisory port.
• Remote connection involves an update in the management station’s screen in
order to receive Traps.
Initializing CM-2
The management module of the CM-2 module is designed for plug-and-play
support. As explained above, this includes automatic identification of the modules
installed in LRS-24, the management protocols that can be used for each module,
the preliminary configuration data, and other relevant information.
These activities are performed automatically, without any user intervention:
• Upon power-up
• Upon inserting or removing a module
• Upon moving a module to a new position in the enclosure.
These capabilities are essential to enable the replacement of modules while
LRS-24 is powered, without disrupting the operation of the equipment. In
addition, the CM-2 module includes provisions to ensure that the service provided
by the links supported by the modules installed in LRS-24 is not disrupted when
the module is temporarily removed, or even when the CM-2 module is completely
replaced. However, when the CM-2 module is removed, it is not possible to
perform monitoring and configuration activities.
The functions performed during initialization are adapted to the management
requirements of each type of module.
Modules with Internal SNMP Agent
The CM-2 module does not store parameters for modules with an internal SNMP
agent because they store their configuration data locally. However, the CM-2
module must detect the presence of these modules (whether present upon
power-up or inserted later), and transfer the configuration parameters needed for
starting the management communication.
