Then wait for the automatic restart after the reset is complete, the default user name, password is netscreen, the default IP is 192.168.1.1
Second, the OS upgrade
Before upgrading, it is a good idea to back up the old OS image.
1. Set up a TFTP server, the address of the TFTP server and the firewall in the same network segment, you can access each other. Assuming that the firewall's trust IP is the IP of the 192.168.1.1,TFTP server is 192.168.1.100, then put the new NetScreen OS on the TFTP server.
2. Back up the old OS image
With the command:
ns5xp-> save software from Flash to TFTP 192.168.1.100 ns5xp.4.0.0r6.0
ns5xp.4.0.0r6.0 is the name of the file to be saved, you can take it yourself.
3. Refresh the OS image to the firewall
Refreshing the OS can be either a Web interface or a CLI command line. The Web page is very simple and is no longer explained here.
Command:
Save software from tftp 192.168.1.100 ns5xp.5.0.0r9.0 to Flash
ns5xp.5.0.0r9.0 is the file name of the new OS image to be refreshed, the command displays a large string of symbols after execution, and then displays information such as whether the file downloaded from TFTP is successful or not:
Save to Flash. It may take a few minutes ... update new flash image (013b5780,24
