IMPORTANT: If you are updating an existing server in an offline environment, obtain the latest version of HPE
SSA through Service Pack for ProLiant before performing configuration procedures.
Using one of multiple methods, you can run HPE SSA before launching the host operating system. In offline mode,
users can configure or maintain detected and supported devices, such as optional Smart Array controllers and
integrated Smart Array controllers. Some HPE SSA features are only available in the offline environment, such as
setting the boot controller and boot volume.
• Accessing HPE SSA in the online environment
This method requires an administrator to download the HPE SSA executables and install them. You can run HPE SSA
online after launching the host operating system.
For more information, see HPE Smart Array SR Gen10 Configuration Guide at the
Hewlett Packard Enterprise website.
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.
• In UEFI boot mode, Hewlett Packard Enterprise provides legacy USB support in the preboot environment before the
operating system loads for USB 1.0, USB 2.0, and USB 3.0 speeds.
• In legacy boot mode, Hewlett Packard Enterprise provides legacy USB support in the preboot environment before the
operating system loads for USB 1.0 and USB 2.0 speeds. USB 3.0 ports can be used with all devices in legacy 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 of the USB ports is configurable in the
Keeping the system current
Firmware
Firmware is a software program that is stored in the system ROM chip on the system board or to an optional controller.
Firmware controls the system when it is first powered on and then passes control to the operating system.
The firmware on the system board of the server is called the system ROM or the BIOS. The firmware on another piece of
hardware configured in the server is called the option ROM.
Firmware update
Update the firmware (also called "flashing the ROM") as part of regular server maintenance. In addition, check for specific
firmware updates in between regular updates to help keep the server performing optimally.
Firmware updates are created for, but are not limited to, the following reasons:
• To provide critical problem fixes that ensure system stability, such as upgrades that might prevent server
unresponsiveness and other issues that could put the system at risk.
• To correct product issues, such as ROM or processor functionality.
• To improve system performance or make the system more serviceable.
