Legacy USB support provides USB functionality in environments where USB support is normally not available. Specifically, HP provides legacy USB functionality for: • POST • RBSU • Diagnostics • DOS • Operating environments which do not provide native USB support For more information on ProLiant USB support, refer to the HP website (http://h18004.www1.hp.com/products/servers/platforms/usb-support.html). Internal USB functionality An internal USB connector is available for use with security key devices and USB drive keys. This solution provides for use of a permanent USB key installed in the internal connector, avoiding issues of clearance on the front of the rack and physical access to secure data. For additional security, external USB functionality can be disabled through RBSU. Disabling external USB support in RBSU disables the USB connectors on the local I/O cable. Internal USB functionality is unaffected. Diagnostic tools 52

Internal USB functionality
An internal USB connector is available for use with security key devices and USB drive keys. This solution
provides for use of a permanent USB key installed in the internal connector, avoiding issues of clearance
on the front of the rack and physical access to secure data.
For additional security, external USB functionality can be disabled through RBSU. Disabling external USB
support in RBSU disables the USB connectors on the local I/O cable. Internal USB functionality is
unaffected.
