Saving Your Parameter Changes
When you make a change to a switch parameter, the change is, in most
cases, immediately activated on the switch as soon as you enter it.
However, a parameter change is initially saved only to temporary
memory by the switch and will be lost the next time you reset or power
cycle the unit. To permanently save a change, you must select the S -
Save Configuration Changes option. You should select that menu option
whenever you have made a change to a switch parameter that you want
the switch to retain even when it is reset or power cycled. If you do not
see the menu option, then there are no parameter changes to be saved.
