ASR increases server availability by restarting the server within a specified time after a system hang. You can
disable ASR from the System Management Homepage or through UEFI System Utilities.
USB support
Hewlett Packard Enterprise servers support both USB 2.0 ports and USB 3.0 ports. Both port types support
installing all types of USB devices (USB 1.0, USB 2.0, and USB 3.0), but might run at lower speeds in specific
situations:
• USB 3.0 capable devices operate at USB 2.0 speeds when installed in a USB 2.0 port.
• Hewlett Packard Enterprise provides legacy USB support in the pre-boot environment prior to the
operating system loading for USB 1.0, USB 2.0, and USB 3.0 speeds in both the UEFI Boot Mode and the
Legacy Boot Mode.
The pre-OS behavior and default operation of the USB ports is configurable in the UEFI System Utilities, so
that the user can change the default operation of the USB ports. For more information, see the UEFI System
Utilities user guide for your product on the
Hewlett Packard Enterprise website
.
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.
