  • Page 15: Firmware Updates

    Note: Lenovo typically releases firmware in bundles called UpdateXpress System Packs (UXSPs). To ensure that all of the firmware updates are compatible, you should update all firmware at the same time. If you are updating firmware for both the Lenovo XClarity Controller and UEFI, update the firmware for Lenovo XClarity Controller first.
  • Page 16 Machine-type-specific firmware-only UXSPs are also available. See the following table to determine the best Lenovo tool to use for installing and setting up the firmware: Note: The server UEFI settings for option ROM must be set to Auto or UEFI to update firmware using Lenovo XClarity Administrator or Lenovo XClarity Essentials.
  • Page 17 Additional information about using Lenovo XClarity Provisioning Manager to update firmware is available http://sysmgt.lenovofiles.com/help/topic/LXPM/platform_update.html • Lenovo XClarity Controller If you need to install a specific update, you can use the Lenovo XClarity Controller interface for a specific server. Notes: – To perform an in-band update through Windows or Linux, the operating system driver must be installed and the Ethernet-over-USB (sometimes called LAN over USB) interface must be enabled.

  • Page 18: Configuring The Lan Over Usb Interface Manually

    Lenovo XClarity Essentials OneCLI is a collection of command line applications that can be used to manage Lenovo servers.Its update application can be used to update firmware and device drivers for your servers. The update can be performed within the host operating system of the server (in-band) or remotely through the BMC of the server (out-of-band).
