3.3 Control of ASMi-450 Operation, General
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.
General Operating
Instructions
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.
Display Functions
The ASMi-450 display has the following functions:
• Display of status messages.
• Display of test functions.
• Display of configuration parameters.
