Firmware Image Management
Cisco delivers all firmware updates to Cisco UCS components in bundles of images. Cisco UCS firmware updates are available to be downloaded to fabric interconnects in a Cisco UCS domain in the following bundles:
- Cisco UCS Infrastructure Software Bundle
-
This bundle includes the following firmware images that are required to update the following components:

Note
Cisco UCS Infrastructure Bundle cannot be activated on Cisco UCS Mini and vice versa.
- Cisco UCS B-Series Blade Server Software Bundle
-
This bundle includes the following firmware images that are required to update the firmware for the blade servers in a Cisco UCS domain. In addition to the bundles created for a release, these bundles can also be released between infrastructure bundles to enable Cisco UCS Manager to support a blade server that is not included in the most recent infrastructure bundle.
- Cisco UCS C-Series Rack-Mount UCS-Managed Server Software Bundle
-
This bundle includes the following firmware images that are required to update components on rack-mount servers that have been integrated with and are managed by Cisco UCS Manager:

Note
You cannot use this bundle for standalone C-series servers. The firmware management system in those servers cannot interpret the header required by Cisco UCS Manager. For information on how to upgrade standalone C-series servers, see the C-series configuration guides.
Cisco also provides release notes, which you can obtain on the same website from which you obtained the bundles.
Firmware Image Headers
Every firmware image has a header, which includes the following:
Firmware Image Catalog
Cisco UCS Manager provides you with two views of the catalog of firmware images and their contents that have been downloaded to the fabric interconnect:
- Packages
-
This view provides you with a read-only representation of the firmware bundles that have been downloaded onto the fabric interconnect. This view is sorted by image, not by the contents of the image. For packages, you can use this view to see which component images are in each downloaded firmware bundle.
- Images
-
The images view lists the component images available on the system. You cannot use this view to see complete firmware bundles or to group the images by bundle. The information available about each component image includes the name of the component, the image size, the image version, and the vendor and model of the component.
You can use this view to identify the firmware updates available for each component. You can also use this view to delete obsolete and unneeded images. Cisco UCS Manager deletes a package after all images in the package have been deleted.
![]() Tip | Cisco UCS Manager stores the images in bootflash on the fabric interconnect. In a cluster system, space usage in bootflash on both fabric interconnects is the same, because all images are synchronized between them. If Cisco UCS Manager reports that the bootflash is out of space, delete obsolete images to free up space. |
Firmware Image Management for Cisco UCS Mini
Cisco UCS Minisupports 3 image bundles. The infrastructure bundle for Cisco UCS Mini contains UCS 6324 images for kickstart, system, and UCS Manager. The UCS 6324 images work only on Cisco UCS Mini platform. The blades and rack bundles are identical to the classic UCS bundle. The Cisco UCS Mini catalog works on the classic Cisco UCS.
![]() Note | The Cisco UCS infrastructure bundle can be downloaded on Cisco UCS Mini but it cannot be activated. The classic UCS kickstart, system, and UCS Manager cannot be activated on Cisco UCS Mini. No classic UCS infrastructure bundle is released for Release 3.0. |
Obtaining Software Bundles from Cisco
Determine which of the following software bundles you need to update the Cisco UCS domain:
-
Cisco UCS Infrastructure Software Bundle—Required for all Cisco UCS domains.
-
Cisco UCS B-Series Blade Server Software Bundle—Required for all Cisco UCS domains that include blade servers.
-
Cisco UCS C-Series Rack-Mount UCS-Managed Server Software Bundle—Only required for Cisco UCS domains that include integrated rack-mount servers. This bundle contains firmware to enable Cisco UCS Manager to manage those servers and is not applicable to standalone C-Series rack-mount servers.

What to Do Next
Download the software bundles to the fabric interconnect.
Downloading Firmware Images to the Fabric Interconnect from a Remote Location
![]() Note | In a cluster setup, the image file for the firmware bundle is downloaded to both fabric interconnects, regardless of which fabric interconnect is used to initiate the download. Cisco UCS Manager maintains all firmware packages and images in both fabric interconnects in sync. If one fabric interconnect is down, the download finishes successfully. The images are synced to the other fabric interconnect when it comes back online. |
Obtain the required firmware bundles from Cisco.
What to Do Next
After the image file for the firmware bundles download completes, update the firmware on the endpoints.
Downloading Firmware Images to the Fabric Interconnect from the Local File System
![]() Note | In a cluster setup, the image file for the firmware bundle is downloaded to both fabric interconnects, regardless of which fabric interconnect is used to initiate the download. Cisco UCS Manager maintains all firmware packages and images in both fabric interconnects in sync. If one fabric interconnect is down, the download finishes successfully. The images are synced to the other fabric interconnect when it comes back online. |
Obtain the required firmware bundles from Cisco.
| Step 1 | In the Navigation pane, click Equipment. | ||
| Step 2 | Click the Equipment node. | ||
| Step 3 | In the Work pane, click the Firmware Management tab. | ||
| Step 4 | Click the Installed Firmware tab. | ||
| Step 5 | Click Download Firmware. | ||
| Step 6 | In the Download Firmware dialog box, click the Local File System radio button in the Location of the Image File field. | ||
| Step 7 | In the
Filename field, type the full path and and name of
the image file.
If you do not know the exact path to the folder where the firmware image file is located, click Browse and navigate to the file.
| ||
| Step 8 | Click
OK.
Cisco UCS Manager GUI begins downloading the firmware bundle to the fabric interconnect. | ||
| Step 9 | (Optional)
Monitor the
status of the firmware bundle download on the
Download
Tasks tab.
| ||
| Step 10 | Repeat this task until all the required firmware bundles have been downloaded to the fabric interconnect. |
What to Do Next
After the image file for the firmware bundles download completes, update the firmware on the endpoints.
Canceling an Image Download
You can cancel the download task for an image only while it is in progress. After the image has downloaded, deleting the download task does not delete the image that was downloaded. You cannot cancel the FSM related to the image download task.
Determining the Contents of a Firmware Package
Checking the Available Space on a Fabric Interconnect
If an image download fails, check whether the bootflash on the fabric interconnect or fabric interconnects in the Cisco UCS has sufficient available space.
| Step 1 | In the Navigation pane, click Equipment. |
| Step 2 | Expand . |
| Step 3 | Click the fabric interconnect on which you want to check the available space. |
| Step 4 | In the Work pane, click the General tab. |
| Step 5 | Expand the
Local Storage Information area.
When you download a firmware image bundle, a fabric interconnect needs at least twice as much available space as the size of the firmware image bundle. If the bootflash does not have sufficient space, delete the obsolete firmware, core files, and other unneeded objects from the fabric interconnect. |
