CSS Software Overview Chapter 1 Managing the CSS Software CSS Software Overview The CSS software contains the files needed to run the CSS, including boot files, directories for archiving and logging files, and MIB files. This software is pre-installed on the CSS conventional hard disk or on an optional Flash disk, which is a Flash memory-based storage device. The CSS software is approximately 50 MB, and you can install a maximum of two software versions. The CSS software image is available from the Cisco Systems website (www.cisco.com) as an ArrowPoint Distribution Image (ADI), network boot ZIP (.zip) image, or GZIP-compressed (adi-gz) image. You can install the CSS software on an FTP server, which the CSS accesses through the File Transfer Protocol (FTP). The CSS accesses the ADI or GZIP file containing the CSS software from an FTP server, copies the file to the CSS disk, and unpacks it. The CSS then boots from the disk. You can also install the CSS software on a network-mounted drive on a remote system, which the CSS accesses through FTP. Network boot uses a special ZIP version of WebNS that ends with a .zip extension. Instead of the CSS disk, the network file system contains the CSS software. This software must be copied and uncompressed on the network drive. Refer to Chapter 2, Specifying the CSS Boot Configuration, for information on booting the CSS, including from a network boot drive. The CSS software version format is shown in Figure 1-1.
