How to take backup & Restore of SAN 300 switch, i dont have FTP,
there are multiple ways how to collect config:
From linux server, you may use SCP.
If you dont have FTP you may use MobaXterm and turn on FTP or SSH server to download config. Of course you have to be in same netwrok as switch.
Do you have brocade branded USB? Then you may download config to usb stick and restore it.
Everything is described in FOS admin guide, so please check it and then try to ask questions.
