HPE Insight Remote Support
Hewlett Packard Enterprise strongly recommends that you register your device for remote support to enable
enhanced delivery of your Hewlett Packard Enterprise warranty, HPE support services, or Hewlett Packard
Enterprise contractual support agreement. Insight Remote Support supplements your monitoring continuously
to ensure maximum system availability by providing intelligent event diagnosis, and automatic, secure
submission of hardware event notifications to Hewlett Packard Enterprise, which will initiate a fast and
accurate resolution, based on your product's service level. Notifications can be sent to your authorized
Hewlett Packard Enterprise Channel Partner for onsite service, if configured and available in your country.
For more information, see Insight Remote Support and Insight Online Setup Guide for ProLiant Servers and
BladeSystem c-Class Enclosures on the Hewlett Packard Enterprise website. Insight Remote Support is
available as part of Hewlett Packard Enterprise Warranty, HPE support services, or Hewlett Packard
Enterprise contractual support agreement.
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 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.
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.
