Obtaining the Latest Level of Switch Firmware
If firmware updates are available, you can download them from 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.
Attention:
•
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
Application Guide
and
Command Reference
for your specific switch and firmware version.
•
Installing the incorrect firmware might cause the switch to malfunction. Before
you install 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 or requirements for updating from an early
firmware version to the latest version.
Upgrading the Switch Firmware
You can upgrade the switch firmware by using an FTP, TFTP or SFTP file server.
Typically, the file server runs as an application under your operating system. Make
sure that the file server application is installed on your file server; then, download
the switch firmware images from the Lenovo website into a directory on your file
server. Then enable the file server and set its default directory to the directory where
the switch firmware image resides.
Note:
Updating the firmware involves rebooting the switch. If you have made any
configuration changes you wish to persist beyond the upgrade process, you
must type the
copy
running-config
startup-config
command. This
command stores the current switch configuration and all changes to
nonvolatile memory.
To transfer the switch firmware image files from the FTP, TFTP or SFTP file server to
the switch, you can establish a Secure Shell (SSH) v2 or Telnet session through the
CMM. Ping the file server to make sure that you have a connection. The session
performs optimally if all three network entities (file server, CMM, and switch IP
addresses) are on the same subnet. Otherwise, you must use a router and
configure a gateway address on the switch. Use the management-module interface
to configure the IP addresses of the CMM external interface (eth0) and the switch so
that they are both on the same subnet as the file server.
