HP's IP Console Switch G2 with Virtual Media and Common Access Card (CAC) support is a key component in managing the heterogeneous data centre and along with the IP Viewer software allows remote access to multiple servers running various operating systems. Virtual media capability allows a removable drive or ISO image to be remotely mapped to an attached server in the data centre or a remote office for software installations and upgrades. An intuitive user interface provides menus for configuration, virtual media, display, and even security and upgrades from the local console. The term CAC stands for Common Access Card, also known as "Smart Cards". The CAC allows government agency and other company employees to keep all of their network access information on a card that is read by either an external USB reader or a port on the PC/server.
