Configuration and Monitoring

An example of the Newton Configurator is shown in

. Newton

Control Panel parameters are listed in

Table 8 on page 59

.

Figure 27. Newton Configurator Example

Web Browser Interface

The web browser interface provides a graphical representation of module
configuration and monitoring.

Use of the web interface offers the following considerations (when appli-
cable for the module):

•

Provides complete access to all module status and configuration func-
tions, including factory parameter default recalls, slot configuration,
and SNMP monitoring controls.

•

Web access will require some normal network time delays for pro-
cessing of information.

•

Configuration parameter changes may require pressing

Apply

button or

Enter

, upload processing time,

and a manual screen refresh to become

effective.

•

Web interface recommended for setting up module and reporting
status for SNMP and monitoring.

Refer to the Frame Status page shown in

Figure 28 on page 41

. The modules

can be addressed by clicking either on a specific module icon in the frame
status display or on a module name or slot number in the link list on the
left.
