Legacy USB support provides USB functionality in environments where USB support is not available
normally. Specifically, Hewlett Packard Enterprise provides legacy USB functionality for the following:
•
POST (system boot)
•
UEFI System Utilities
•
Preboot UEFI shell
•
DOS
•
Operating environments that do not provide native USB support
External USB functionality
Hewlett Packard Enterprise provides external USB support to enable local connection of USB devices for
server administration, configuration, and diagnostic procedures.
For additional security, external USB functionality can be disabled through USB options in UEFI System
Utilities.
Redundant ROM support
The server enables you to upgrade or configure the ROM safely with redundant ROM support. The server
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, the flashing mechanism 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
