Diagnostic tools 55
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.
External USB functionality
HP provides external USB support to enable local connection of USB devices for server blade
administration, configuration, and diagnostic procedures. For more information, see "Using the HP c-
Class Blade SUV Cable (on page 50)."
For additional security, external USB functionality can be disabled through RBSU. Disabling external USB
support in RBSU disables the USB connectors on the HP c-Class Blade SUV Cable.
