    If Lenovo determines that the levels of particulates or gases in your environment have caused damage to the device, Lenovo may condition provision of repair or replacement of devices or parts on implementation of appropriate remedial measures to mitigate such environmental contamination.

  • Page 18: Firmware Updates

    You can use the tools listed here to update the most current firmware for your server and the devices that are installed in the server. 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 BMC and UEFI, update the firmware for BMC first.
  • Page 19 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 UEFI to update the firmware using Lenovo XClarity Essentials.
