Firmware updates
Several o tions are available to u date the firmware for the server.
You can use the tools listed here to u date the most current firmware for your server and the devices that are
installed in the server.
Note: Lenovo ty ically releases firmware in bundles called U dateX ress System Packs (UXSPs). To ensure
that all of the firmware u dates are com atible, you should u date all firmware at the same time. If you are
u dating firmware for both the Lenovo XClarity Controller and UEFI, u date the firmware for Lenovo XClarity
Controller first.
Best ractices related to u dating firmware are available at the following location:
htt ://lenovo ress.com/LP0656
Important terminology
• In-band update. The installation or u date is erformed using a tool or a lication within an o erating
system that is executing on the server’s core rocessor.
• Out-of-band update. The installation or u date is erformed by the Lenovo XClarity Controller collecting
the u date and then directing the u date to the target subsystem or device. Out-of-band u dates have no
de endency on an o erating system executing on the core rocessor. However, most out-of-band
o erations do require the server to be in the S0 (Working) ower state.
• On-Target update. The installation or u date is initiated from an o erating system running on the server.
• Off-Target update. The installation or u date is initiated from a com uting device interacting directly with
the server’s Lenovo XClarity Controller.
• UpdateXpress System Packs (UXSPs). UXSPs are bundled u dates designed and tested to rovide the
interde endent level of functionality, erformance, and com atibility. UXSPs are server machine-ty e
s ecific and are built (with firmware and device driver u dates) to su ort s ecific Windows Server, Red
Hat Enter rise Linux (RHEL) and SUSE Linux Enter rise Server (SLES) o erating system distributions.
Machine-ty e-s ecific firmware-only UXSPs are also available.

From Lenovo XClarity Provisioning Manager V3, you can u date the Lenovo XClarity Controller firmware,
the UEFI firmware, and the Lenovo XClarity Provisioning Manager V3 software.
Note: By default, the Lenovo XClarity Provisioning Manager V3 Gra hical User Interface (GUI) is

• Lenovo XClarity Controller
If you need to install a s ecific u date, you can use the Lenovo XClarity Controller interface for a s ecific
server.
Notes:
– To erform an in-band u date through Windows or Linux, the o erating system driver must be installed
and the Ethernet-over-USB (sometimes called LAN over USB) interface must be enabled.
Additional information about configuring Ethernet over USB is available at:

Turn on the server
After the server erforms a short self-test ( ower status LED flashes quickly) when connected to in ut ower,
it enters a standby state ( ower status LED flashes once er second).
The server can be turned on ( ower LED on) in any of the following ways:
• You can ress the ower button.
• The server can restart automatically after a ower interru tion.
• The server can res ond to remote ower-on requests sent to the Lenovo XClarity Controller.
For information about owering off the server, see “Turn off the server” on age 10.
Turn off the server
The server remains in a standby state when it is connected to a ower source, allowing the Lenovo XClarity
Controller to res ond to remote ower-on requests. To remove all ower from the server ( ower status LED
off), you must disconnect all ower cables.
To lace the server in a standby state ( ower status LED flashes once er second):
Note: The Lenovo XClarity Controller can lace the server in a standby state as an automatic res onse to a
critical system failure.
• Start an orderly shutdown using the o erating system (if su orted by your o erating system).
• Press the ower button to start an orderly shutdown (if su orted by your o erating system).
• Press and hold the ower button for more than 4 seconds to force a shutdown.
When in a standby state, the server can res ond to remote ower-on requests sent to the Lenovo XClarity
Controller. For information about owering on the server, see “Turn on the server” on age 10.
