   • Reboot in number of minutes—Reboots the device in the number of minutes from now that you specify.

   • Halt Immediately—Stops the device software immediately. After the software has stopped, you can access the device through the console port only.
3. Choose the boot device from the Reboot from media list:
   • compact-flash—Reboots from the internal CompactFlash card. This selection is the default choice.
   • removable-compact-flash—Reboots from the optional external compact CompactFlash card. This selection is available on J2320 and J2350 Services Routers only.

4. (Optional) In the Message box, type a message to be displayed to any users on the device before the reboot occurs.
5. Click Schedule. The J-Web interface requests confirmation to perform the reboot or halt.
6. Click OK to confirm the operation.
   • If the reboot is scheduled to occur immediately, the device reboots. You cannot access the J-Web interface until the device has restarted and the boot sequence is complete. After the reboot is complete, refresh the browser window to display the J-Web interface login page.
   • If the reboot is scheduled to occur in the future, the Reboot page displays the time until reboot. You have the option to cancel the request by clicking Cancel Reboot on the J-Web interface Reboot page.
