Firmware updates
Several options are available to update the firmware for the server.
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 Lenovo XClarity Controller and UEFI, update the firmware for Lenovo XClarity
Controller first.
Best practices related to updating firmware are available at the following location:

Important terminology
• In-band update. The installation or update is performed using a tool or application within an operating
system that is executing on the server's core processor.
• Out-of-band update. The installation or update is performed by the Lenovo XClarity Controller collecting
the update and then directing the update to the target subsystem or device. Out-of-band updates have no
dependency on an operating system executing on the core processor. However, most out-of-band
operations do require the server to be in the S0 (Working) power state.
• On-Target update. The installation or update is initiated from an operating system running on the server.
• Off-Target update. The installation or update is initiated from a computing device interacting directly with
the server's Lenovo XClarity Controller.
• UpdateXpress System Packs (UXSPs). UXSPs are bundled updates designed and tested to provide the
interdependent level of functionality, performance, and compatibility. UXSPs are server machine-type
specific and are built (with firmware and device driver updates) to support specific Windows Server, Red
Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES) operating system distributions.
Machine-type-specific firmware-only UXSPs are also available.
Description
• Sound power levels, idle
– 6.3 bels, typical
– 6.5 bels, maximum
• Sound power levels, operating
– 6.7 bels, typical
– 6.9 bels, maximum
Notes:
• These sound power levels are measured in controlled acoustical environments according
to procedures specified by ISO 7779 and are reported in accordance with ISO 9296.
• The declared acoustic noise levels are based on specified configurations, which may
change slightly depending on configuration and conditions.
Your server complies with ASHRAE class A2 specifications. Depending on the hardware
configuration, some server models comply with ASHRAE class A3 and class A4
specifications, see "ASHRAE class compliance information" on page 446.
