Cisco Cisco Firepower Management Center 2000

Tasks that are running when the uninstallation begins are stopped, become failed tasks, and cannot be 
resumed; you must manually delete them from the task queue after the uninstallation completes. The task 
queue automatically refreshes every 10 seconds. You must wait until any long-running tasks are 
complete before you begin the uninstallation.

Select 

.

The Product Updates tab appears.

Click the install icon next to the uninstaller that matches the update you want to remove.

The Install Update page appears. 

Select the Defense Center and click 

, then confirm that you want to uninstall the update and reboot 

the device.

The uninstallation process begins. You can monitor the uninstallation progress in the task queue (

).

Do not use the web interface to perform any other tasks until the uninstallation has completed and the 
Defense Center reboots. Before the uninstallation completes, the web interface may become unavailable 
and the Defense Center may log you out. This is expected behavior; log in again to view the task queue. 
If the uninstallation is still running, do not use the web interface until the uninstallation has completed. 
If you encounter issues with the uninstallation (for example, if the task queue indicates that the update 
has failed or if a manual refresh of the task queue shows no progress for several minutes), do not restart 
the uninstallation. Instead, contact Support.

After the uninstallation finishes, clear your browser cache and force a reload of the browser. Otherwise, 
the user interface may exhibit unexpected behavior.

Log in to the Defense Center.

Select 

 and confirm that the software version is listed correctly: Version 5.3.1.

Verify that the appliances in your deployment are successfully communicating and that there are no 
issues reported by the health monitor.
