Before you proceed with the upgrade, ensure to always backup the configuration. Please refer to the following link on how to backup configuration in EXOS.
- Software upgrade procedure:
Step 1. Decide what version you want to upgrade.
The following link provides recommended EXOS and Switch Engine releases for each hardware platform.
Follow the steps in the article link below
※ Image File Names: You can identify the appropriate image or module for your platform based on the file name prefix of the image.
You can determine the appropriate image for your switch by navigating to the Extreme Portal, and then navigating to Products > ExtremeSwitching > (Select Model), where you will only be shown downloads for the selected model.
Step 3. Place the EXOS image on a TFTP server.
Step 4. Ensure that you are able to ping the TFTP server from the switch from the appropriate virtual router.
At least one of ping vr vr-Mgmt
exos_switch.1
# ping vr vr-mgmt 192.168.1.2
Ping(ICMP) 192.168.1.2:

Step 5. Type the command download image.
Reboot the system for the upgrade to take effect: Type reboot, then when asked if you want to reboot the switch now, type yes.
exos_switch.1
# download image 192.168.1.2
summitX-22.6.1.4-patch2-4.xos vr vr-mgmt

4. After rebooting the switch, type the command 'show version' and check the upgrade version.

- Additional notes
If upgrading a BlackDiamond chassis with two MSMs, then follow the steps above only on the Master MSM – after which it will automatically synchronize with the Backup.
It is unnecessary to specify the partition on which to load the new image, because by default it will be downloaded and installed on the non-active partition.
If XMODs are utilized in your environment, then install them prior to rebooting.
Upgrading via ScreenPlay is not currently supported in EXOS and must be done through the CLI.
By default, TFTP is used to transfer the EXOS image. The image can also be transferred via SCP or via USB (if the switch has a USB port). See the articles linked below for further details:
