Overview of Firmware
C-Series servers use firmware downloaded from cisco.com. This firmware is certified by Cisco to upgrade
firmware on a C-Series server.
The firmware you downloads is packaged in a .zip file. After you have downloaded a firmware .zip from
Cisco, you can use it to update the firmware on your server. Cisco also provides release notes with each image,
which you can obtain from the same website from which you obtained the image.
Do not use the .zip file to reimage your server.Warning
You use a .bin file to reimage. You must extract the proper .bin upgrade file from this .zip file. You can extract
this .bin to a TFTP server or your local machine.
When you update the firmware, you can either upgrade an older firmware version to a newer one, or
downgrade a newer firmware version to an older one.
Note
The CIMC separates the firmware update process into stages to ensure that you can install the firmware to a
component while the server is running without affecting its uptime. Because you do not need to reboot the
server until after you activate, you can perform that task overnight or during other maintenance periods. When
you update firmware, the following stages occur:
