Parameter Verification

Normally when you change a parameter value on the controller or any module using the HTTP interface, the change takes place immediately. However, some parameters require validation before the change can be made. If you apply a parameter set requiring validation, a dialog box appears, indicating that validation is underway. If the change passes the validation, the dialog box closes when the check is complete. If a parameter does not pass validation, the parameter is surrounded by a red box. Hover your mouse over the top right corner of the red box to see an explanation of the error.

Parameter values are left at their original settings (the setting in effect prior to attempting to apply the invalid parameter setting(s)). If you navigate away from a page with invalid parameter settings, a dialog box indicates the following:

There are errors in setting parameter value(s) on this page. Would you like to drop the changes?

You have two choices:

• Yes—cancels the changes and reverts to previous settings.
• No—Returns the GUI to the page with the errors so you can change the parameters to (new) valid values.
