the 4100 supports up to FOS 6.4 where last release is 6.4.3h. I would rather aim for FOS 6.4 than FOS 5.1. Why do you need FOS 5.1?

The current version of the customer DS-4100B is 5.0.1b.
5.1 version is required for firmware upgrade to 6.x.
I have all other version files for the upgrade.
Is there a way to download 5.1.x?
Thank you for your support.

send me a mail (martin dot sjoelin at brocade dot com) a mail with the output from licenseidshow and the serial number of the switch, and I will see what I can arrange for you.
