If your device stopped responding to WWW management and you can not see it using OSReset software, then please use following guide to restore it to factory default configuration:

- Configure ip address of your computer (Linux based preferably) to 192.168.1.23 netmask 255.255.255.0

- in the shell console please type:

telnet -r 192.168.1.229 9000

but don't press enter just yet.

- power on the device - as soon as the ethernet LED stops to blink press enter on the shell console to execute the 'telnet' command

[root@jumper rewt]# telnet -r 192.168.1.229 9000

After connecting please press CTRL+C immediately.

Important: the telnet client must be run in so called character mode (hence the -r switch) so it sends each typed character separately.

Now, please enter following commands:

fis erase -f 0x500a0000 -l 0x00001000
fis erase -f 0x50180000 -l 0x00100000

And after pressing <ENTER> you should see:

OSBRiDGE> fis erase -f 0x500a0000 -l 0x00001000
... Erase from 0x500a0000-0x500a1000: ................
OSBRiDGE> fis erase -f 0x50180000 -l 0x00100000
... Erase from 0x50180000-0x50280000: ................
