Server Software and Configuration Utilities 71 USB Support HP provides both standard USB support and legacy USB support. Standard support is provided by the operating system through the appropriate USB device drivers. HP provides support for USB devices before the operating system loading through legacy USB support, which is enabled by default in the system ROM. HP hardware supports USB version 1.1 or 2.0, depending on the version of the hardware. 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 USB drive keys only. The internal connector shares the same bus with the front external USB connector, and connecting a device to both the front internal and front external USB connectors is not supported. This solution provides for use of a permanent boot drive from a USB drive key installed in the front internal connector, avoiding issues of clearance on the front of the rack and physical access to secure data. For additional security, you can individually disable the front, rear, and internal USB connectors through RBSU. Disabling the rear USB connectors in RBSU disables both rear USB ports.

Internal USB Functionality
An internal USB connector is available for use with USB drive keys only. The
internal connector shares the same bus with the front external USB connector,
and connecting a device to both the front internal and front external USB
connectors is not supported. This solution provides for use of a permanent boot
drive from a USB drive key installed in the front internal connector, avoiding
issues of clearance on the front of the rack and physical access to secure data.
For additional security, you can individually disable the front, rear, and internal
USB connectors through RBSU. Disabling the rear USB connectors in RBSU
disables both rear USB ports.
