Usage 
Information
RFC 3986 specifies that IPv6 host addresses in a uniform resource identifier (URI) must be 
enclosed in square brackets, [X:X:X:X::X]. For maximum flexibility this command accepts IPv6 
host addresses with or without the square brackets.
You must reload FTOS after executing this command. Use the upgrade system stack-
unit (S-Series stack member)
 command to copy FTOS from the management unit 
to one or more stack members.
Example
FTOS# upgrade system ?
ftp:    Copy from remote file system (ftp://
userid:password@hostip/filepath)
scp:    Copy from remote file system (scp://
userid:password@hostip/filepath)
tftp:   Copy from remote file system (tftp://hostip/filepath)
FTOS# upgrade system ftp://username:password@10.11.1.1/FTOS-
SB-7.7.1.0.bin
