System Maintenance
18.1 Demands
1.
DFL-900 is designed to provide upgradeable firmware and database to meet the upcoming dynamics of the Internet. New
features, new attack signatures, new forbidden URLs, and new virus definitions require timely updates to the DFL-900.
This chapter introduces how to upgrade your system with TFTP and Web UI respectively.
2.
Sometimes one may want to reset the firmware to factory default due to loss of password, firmware corrupted,
configuration corrupted. Since DFL-900 does not have a reset button to prevent careless pressing of it, factory default has
to be set with web GUI or console terminal. Of course, when you loss the password, you have to use CLI only because you
can never enter the web GUI with the lost password.
18.2 Steps for TFTP Upgrade
Step 1 ¡ Ð
Setup TFTP server
Place the TFTP server TftpServer.exe in the
c:\ directory and double click to run it. Place all
bin files in the c:\ as well. Set the PC to be
192.168.1.x to be in the same subnet with the
DFL-900's LAN1. Login to DFL-900's console.
Enter en to enter privileged mode. Configure the
LAN1 address so that the DFL-900 can connect
to the TFTP server. The CI command to configure
LAN1
