3.3 Control of ASMi-450 Operation, General
ASMi-450 operating mode is determined by a set of parameters stored in an internal non-volatile memory. These parameters are selected by the user, using the ASMi-450 front panel push-buttons, a supervision terminal, or a network management station (either a generic SNMP management station, or the RADview management station offered by RAD). When a supervision terminal, or a network management station is in control, the ASMi-450 cannot be controlled from the front panel; however, when under the control of a network management station, the front panel can still be used to read the current parameters, status, and statistics.
After the operating parameters have been selected, a process called configuration set-up, the ASMi-450 no longer requires operator attendance. The configuration stored in the ASMi-450 memory is not affected when power is turned off.
Upon turn-on, the ASMi-450 checks the validity of the stored configuration data, and if everything is OK, it assumes the last selected configuration.
∙If the configuration does not require modification, the ASMi-450 is then ready for operation immediately after power is applied.
∙If the configuration data is not valid, the ASMi-450 lets you load instead a default configuration. The default configuration, prepared by the manufacturer, is stored in the program EPROM.
All operations are performed using an interactive, menu-driven user-friendly interface. The interface is controlled by means of the display and three push- buttons. The ASMi-450 guides you in the execution of the required task by means of simple and clear messages, presents the range of available parameter values and checks your inputs. Moreover, the ASMi-450 will present to you only those parameter values available on your ASMi-450 model in the selected operating mode.
If you make a configuration error, e.g., you select a parameter value that conflicts with the current operating mode, the ASMi-450 rejects the erroneous selection and displays an error message that identifies the error.
You will find detailed instructions for operating the ASMi-450 in Section 3-6 and 3-7. Section 3-8 explains the configuration error messages, and presents instructions for correcting the problem.
The ASMi-450 display has the following functions:
∙Display of status messages.
∙Display of test functions.
∙Display of configuration parameters.
