DFL-900/1500 User Manual
Ans：
Under this circumstance, the DFL-1500 will automatically reboot and all configurations will still remain as before.
While I am upgrading firmware from local disk, the download is complete. After md5 checks, the screen appears "Upgrading
10.
kernel image". What will it happen if the power is off suddenly?
Ans：
Almost all the cases will not cause firmware fail. The DFL-1500 will automatically reboot and all configurations will still
remain as before. But sometimes it will make firmware fail. If the firmware fails, DFL-1500 will automatically enter rescue mode
when it reboots. You may need to do the factory reset, and then restore your original configuration to DFL-1500. Refer to the
factory reset procedure of DFL-1500 as Section 29.5. About restoring configuration procedure, please refer to Section 29.7.

Be sure that you have cleaned all the file cache in the browser, and try to connect the internet web server. If the web page
result still does not match with the web filter configuration, you may close your browser and reopen it.
