operating system is functioning properly, the system periodically resets the timer. However, when the operating system fails, the timer expires and restarts the server. ASR increases server availability by restarting the server within a specified time after a system hang. At the same time, the HP SIM console notifies you by sending a message to a designated pager number that ASR has restarted the system. You can disable ASR from the System Management Homepage or through RBSU. USB support HP provides both standard USB 2.0 support and legacy USB 2.0 support. Standard support is provided by the OS through the appropriate USB device drivers. Before the OS loads, HP provides support for USB devices through legacy USB support, which is enabled by default in the system ROM. Legacy USB support provides USB functionality in environments where USB support is not available normally. Specifically, HP provides legacy USB functionality for the following: • POST • RBSU • Diagnostics • DOS • Operating environments which do not provide native USB support Redundant ROM support The node enables you to upgrade or configure the ROM safely with redundant ROM support. The node has a single ROM that acts as two separate ROM images. In the standard implementation, one side of the ROM contains the current ROM program version, while the other side of the ROM contains a backup version. NOTE: The server ships with the same version programmed on each side of the ROM. Safety and security benefits When you flash the system ROM, ROMPaq writes over the backup ROM and saves the current ROM as a backup, enabling you to switch easily to the alternate ROM version if the new ROM becomes corrupted for any reason. This feature protects the existing ROM version, even if you experience a power failure while flashing the ROM. Keeping the system current Drivers IMPORTANT: Always perform a backup before installing or updating device drivers. The node includes new hardware that may not have driver support on all OS installation media. If you are installing an Intelligent Provisioning-supported OS, use Intelligent Provisioning (on page 70) and its Perform Maintenance feature to install the latest supported drivers.
