M620 automatic firmware updates via FTP?? - LC023: Cannot access network share.

Hi, 

Could someone please the settings to use in the update section via ftp, namely:

FTP Server Settings
FTP Address 
User Name 
Password 
Catalog Location 
Catalog Filename (optional)

I've tried "ftp.dell.com", with login "anonymous" password an email (tried email with - in front as well), catalog location "/catalog" and catalog filename "catalog.cab"..

I keep getting this error:

LC023: Cannot access network share. Check network share access credentials (IP address, user name, password, share type, and so on). Refer to Lifecycle Controller Profile documentation for more details.

Can anyone advise on a solution here please.

TY
