G8264 Installation Guide
If firmware updates are available, you can download them from the Lenovo
website. The switch might have features that are not described in the
documentation that comes with the switch, and the documentation might be
updated occasionally to include information about those features, or technical
updates might be available to provide additional information that is not included in
the switch documentation.
Configuration settings are lost during a firmware update. Before updating the
firmware, save a copy of the configuration to a separate device. In the event of a
failed update, the saved configuration can be restored. For more information about
the configuration file, see the Command Reference guide for your specific switch and
firmware version.
Attention: Installing the wrong firmware update might cause the network switch to
malfunction. Before you install a firmware, read any release notes, readme files and
change history files that are provided with the downloaded update. These files
contain important information about the update and the procedure for installing the
update, including any special procedure for updating from an early firmware version
to the latest version.
To check for firmware and documentation updates, go to the Lenovo website:
http://support.lenovo.com/
Note: Changes are made periodically to the Lenovo website. Procedures for
locating firmware and documentation might vary slightly from what is described
in this document.

switch to factory defaults, or to recover from a failed firmware download.
You can interrupt the boot process and enter the Boot Management menu from the
