3.3  Saving and Resetting the Device 
To apply configuration changes to the device's volatile memory (RAM), click the Submit 
 button located on the page in which you are configuring. Modifications to parameters 
with on-the-fly capabilities are immediately applied to the device; other parameters are 
applied only after a device reset. However, parameters saved to the volatile memory revert 
to their previous settings after a hardware or software reset (or if the device is powered 
down). Therefore, to ensure that all parameter changes (whether on-the-fly or not) are 
retained, you need to save ('burn') them to the device's non-volatile memory (i.e., flash). 
You can also "gracefully lock" the device so that no new calls are allowed and existing calls 
are terminated only after a user-defined period. This is useful when, for example, you are 
uploading new software files to the device and you don't want to disrupt existing traffic. 
 
 
Note:
 
Parameters preceded by the lightning   sign are not changeable on-the-fly 
and require a device reset. 
 
¾  To save parameters to flash memory and reset the device: 
1.  On the toolbar, click Device Actions, and then from the drop-down list, choose Reset; 
the 'Maintenance Actions' page appears. 
Figure  3-6: Maintenance Actions Page 
 
2.  Under the 'Reset Configuration' group, ensure that 'Yes' is selected in the 'Burn to 
FLASH' drop-down list. 
3.  (Optional) To gracefully lock the device, click the LOCK  button, from the 'Graceful 
Option' drop-down list select 'Yes', and then define the time (in seconds) after which 
the device locks. 
4.  Click the Reset button.
