For maximum compatibility of USB 3.0 devices with all operating systems, Hewlett Packard Enterprise
provides a configuration setting for USB 3.0 Mode. Auto is the default setting. This setting impacts USB 3.0
devices when connected to USB 3.0 ports in the following manner:
•
Auto (default)—If configured in Auto Mode, USB 3.0 capable devices operate at USB 2.0 speeds in the
preboot environment and during boot. When a USB 3.0 capable OS USB driver loads, USB 3.0 devices
transition to USB 3.0 speeds. This mode is compatible with operating systems that do not support USB 3.0
while allowing USB 3.0 devices to operate at USB 3.0 speeds with state-of-the-art operating systems.
•
Enabled—If Enabled, USB 3.0 capable devices operate at USB 3.0 speeds at all times (including the
preboot environment) when in UEFI Boot Mode. Do not use this mode with operating systems that do not
support USB 3.0. If operating in Legacy Boot BIOS Mode, the USB 3.0 ports cannot function in the preboot
environment and are not bootable.
•
Disabled—If configured for Disabled, USB 3.0 capable devices function at USB 2.0 speeds at all times.
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, 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
Access to Hewlett Packard Enterprise Support Materials
Access to some updates for ProLiant Servers may require product entitlement when accessed through the
Hewlett Packard Enterprise Support Center support portal. Hewlett Packard Enterprise recommends that you
have an HP Passport set up with relevant entitlements. For more information, see the Hewlett Packard
Enterprise website.
Updating firmware or System ROM
Multiple methods exist to update the firmware or System ROM:
•
Service Pack for ProLiant
•
FWUPDATE utility
•
FWUpdate command from within the Embedded UEFI Shell
