Brocade 4/64 (4900 AG457A)

Hi, I have done lots of firmware downloads on Brocade switches, but a have a challenge on 2 Brocade 4/64 that will not accept to upgrade fimrware from 6.32b to 6.40b as describes in the supportet release notes.

its says cannot downgrade to 6.1 or lower. Please downgrade to 6.2 first and then download the disired firmware version. Firmwaredownload failed.

Remenber its on two switches.  So any ideas ?  

The switches has been fastbootet and power down, it did not help.

Regards Finn

I have never ever had problems upgrading from the old levels.

Are you sure you've trying to upgrade to FOS 640b?

With that i mean, are you sure you've downloaded to right FOS zip file from the HP site.

And are sure your FTP server is pointing to the right directory and/or using the right path?

Look (where you unzipped the firmware) for files with names like v6.4.0b or open file like release.plist (or .xml)

They should be located in the SWBD* directories.

The first one matches the fos level contained in the zipfile and if you open release.* you'll notice the fos level in the first 10 lines of the file.
