Downloading a New Image

The ExtremeXOS core image (.xos) file contains the executable code that runs on the switch and is preinstalled at the factory. An ExtremeXOS module image (.xmod) supplements the core image. Note that the version number of the core image and the module must match. As new versions of this image are released, you should upgrade both the software and modular packages running on your system.

To find and install image files:

  1. Point your browser to and log in with your eSupport account.

    If you do not have an eSupport account, you can request one with the Request Web Login link.



    You can also download release notes from the eSupport site. The ExtremeXOS Release Notes will always have the most current download and install instructions.
  2. Find the ExtremeXOS image and all modules you wish to upgrade. Later you will install all files on the image at the same time.
  3. Save the files to a TFTP server on the network. You can also store them on a USB 2.0 device.
  4. When you have all images downloaded and saved, proceed to Finding the Inactive Partition.
