# Perform System Shutdown and Startup

To perform a system shutdown:

CAUTION: You should follow the policies of your site to warn users prior to the system shutdown, because this process removes the server from call processing.

1. From the Main menu, select (S) System Maintenance and then (S) System Shutdown.

2. Type shutdown (lowercase).

3. At the Modules to shutdown? prompt, enter 1.

4. The system displays a warning about call processing being terminated. Enter Y to continue. The system displays the status of each line of the module as "idle," "active" or "stopped," and updates the status every minute until all lines are stopped. The system stops any calls still in progress after five minutes.

5. At the Wait for message waiting queues to clear? prompt, enter Y to wait or N to proceed without waiting.

6. At the Wait for paging queues to clear? prompt, enter Y to wait or N to proceed without waiting.

7. At the Do you want to enter the menu to enable or disable modules? prompt, enter Y if you want to leave a server disabled after the shutdown/reboot (possibly for some offline maintenance) OR enter N to continue with shutdown (skip to step 10).

8. If you entered Y in step 7, module status is displayed. Enter (D) to disable a module or (E) to enable a previously-disabled module.

9. When prompted to select a module ID, enter 1. The module state is changed to your selected state.

10. Press Enter to return to the root # prompt.

11. Type startnpm.

- If you have disabled the module, the system warns you and offers a menu of offline maintenance choices (for example, system.restore, console). Select a maintenance procedure as required. To re-enable the module, type host.status and select (E) to enable.

- If you have just changed the module state to "enabled", the node reboots.

12. The screen displays startup messages and then returns to the root prompt. Type console to return to the Main menu.
