Cisco UCS Firmware Versioning

Document ID: 110512

Updated: Aug 10, 2010



This document explains how to interpret UCS firmware version information and identify components of the UCS firmware.

The Cisco UCS firmware is delivered in these ways:

  • The UCS images are shipped as a single bundle or as individual component images, which include the UCS Manager, UCS Fabric Interconnect, IO module, BMC, BIOS, adapter, etc.

  • The UCS firmware is hosted on the Cisco Software Delivery System.

  • UCS Manager unpacks the bundle and updates the image catalog stored on the switch.

  • The UCS Manager maintains a catalog of all the component images stored on the switch.

  • Only one version of each component is shipped in any bundle. Component images for multiple hardware platforms with UCS are included in the same bundle.

  • Each component image is versioned and customer visible. You can upgrade each component image separately, provided that it is compatible.

The UCS firmware comes in two ways, either in a bundle or in individual images:

  • Bundle:

    • The bundle includes a package for each component that requires firmware.

    • Currently there are three bundles to track:

      • .bin—normal bundle

      • .gbin—bundle with debug information; engineering instructed only

      • dplug—dplug file that allows root access to the NX-OS; engineering instructed only

  • Individual images



Cisco recommends that you have a working knowledge of these:

  • The Cisco UCS Server Blade software and hardware

  • The UCS Manager

  • The impact and implications of the different commands described in this document

  • The UCS components and topology; refer to the network diagram for a typical solution.

Ensure that you meet these requirements before you attempt this configuration:

Components Used

The information in this document is based on Cisco UCS.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a default configuration. If your network is live, make sure that you understand the potential impact of any command.

Network Diagram

A typical Cisco UCS topology looks similar to this:

1. UCS Firmware Version Information

This section describes the UCS firmware version format.


The NX-OS version numbers adhere to the standard Cisco format. For example, 4.0(0)N1.1.

Other UCS Components

Other UCS components adhere to the standard software format (X.Y.Z). For example, 1.0.0.

  • X is a major version/release. It is used for major feature releases or architectural changes

  • Y is a minor version/release.

  • Z is a bug fix version/release.

2. The UCS Firmware Package

The image represents a piece of firmware that is specific to an end point. For example, IOM image, BMC image, etc. Multiple Images are bundled together to form a package. A package is meant only for ease of distribution and download. Unlike the image, a package does not have a version. The UCS manager allows the download of both the package and individual images. If you download a package, it is unpacked, and the individual images are extracted from it. A package is a read-only object that is created when it is downloaded. A package does not occupy any disk space. It represents a list of images that were unpacked as part of the package download. A package cannot be deleted. It is deleted automatically when all the images that came with it are deleted. When an individual image is downloaded, the package name is same as the image name.

Images that are in a package:

  • Fabric-Interconnect Kernel and System images

  • UCS Manager image

  • IOM firmware image

  • BMC firmware image

  • Adapter firmware - network facing (Cisco UCS CNA M71KR , Cisco UCS VIC M81KR )

  • Adapter firmware - host facing (applicable for Cisco UCS CNA M71KR adapter only)

    • Qlogic option ROM

    • Emulex option ROM

    • Emulex firmware

  • LSI option ROM

  • LSI firmware

  • BIOS

3. The UCS Firmware Bundle Overview

In order to see a UCS firmware bundle, complete these steps:

  1. Log into the UCS Manager.

  2. Click the Equipment tab on the Navigation pane.

  3. Click the Firmware Management tab on the Work pane.

  4. Click Package under the Firmware Management tab.

  5. Click the specific firmware bundle.
