• USB 3.0 capable devices operate at USB 2.0 speeds when installed in a USB 2.0 port.
• In UEFI Boot Mode, Hewlett Packard Enterprise provides legacy USB support in the preboot environment
before the operating system loading for USB 1.0, USB 2.0, and USB 3.0 speeds.
• In Legacy BIOS Boot Mode, Hewlett Packard Enterprise provides legacy USB support in the preboot
environment before the operating system loading for USB 1.0 and USB 2.0 speeds. USB 3.0 ports can be
used with all devices in Legacy BIOS Boot Mode but are not available at USB 3.0 speeds in the preboot
environment. Standard USB support (USB support from within the operating system) is provided by the
OS through the appropriate USB device drivers. Support for USB 3.0 varies by operating system.
The pre-OS behavior and default operation of the USB ports is configurable in the UEFI System Utilities. For
more information, see the UEFI System Utilities user guide for your product on the Hewlett Packard
Enterprise website.
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.
