34.3 Locking and Unlocking the Device
The Lock and Unlock option allows you to lock the device so that it doesn't accept any new
calls and maintains only the current calls. This is useful when, for example, you are
uploading new software files to the device and you don't want any traffic to interfere with
the process.

To lock the device:
1. Open the Maintenance Actions page (see ''Basic Maintenance'' on page 539 ).
2. Scroll down to the 'LOCK / UNLOCK' group:
Figure 34-3: Locking the Device
3. From the 'Graceful Option' drop-down list, select one of the following options:
•
Yes: The device is locked only after the user-defined time in the 'Lock Timeout'
field (see Step 3) expires or no more active traffic exists (the earliest thereof). In
addition, no new traffic is accepted.
•
No: The device is locked regardless of traffic. Any existing traffic is terminated
immediately.
Note: These options are only available if the current status of the device is in
UNLOCKED state.
4. If you set 'Graceful Option' to Yes (in the previous step), then in the 'Lock Timeout'
field, enter the time (in seconds) after which the device locks. If no traffic exists and
the time has not yet expired, the device locks immediately.
5. Click the LOCK button; a confirmation message box appears requesting you to
confirm device lock.
