Updating Your Appliances

5. View the task queue (System > Monitoring > Task Status) to make sure that 

there are no tasks in progress.
Tasks that are running when the update begins are stopped, become failed 

tasks, and cannot be resumed; you must manually delete them from the task 

queue after the update completes. The task queue automatically refreshes 

every 10 seconds. You must wait until any long-running tasks are complete 

before you begin the update.

6. Select System > Updates.

The Product Updates tab appears.

7. Click the install icon next to the update you uploaded.

The Install Update page appears.

8. Select the Defense Center and click Install. Confirm that you want to install 

the update and reboot the Defense Center.
The update process begins. You can begin monitoring the update's progress 

in the task queue (System > Monitoring > Task Status). However, after the 

Defense Center completes its necessary pre-update checks, you are logged 

out. When you log back in, the Upgrade Status page appears. The Upgrade 

Status page displays a progress bar and provides details about the script 

currently being run. 
If the update fails for any reason, the page displays an error message 

indicating the time and date of the failure, which script was running when the 

update failed, and instructions on how to contact Support. Do not restart the 

update. 

If you encounter any other issue with the update (for example, if 

a manual refresh of the Update Status page shows no progress for several 

minutes), do not restart the update. Instead, contact Support. 

When the update completes, the Defense Center displays a success 

message and reboots. 

9. After the update finishes, clear your browser cache and force a reload of the 

browser. Otherwise, the user interface may exhibit unexpected behavior.

10. Log into the Defense Center.
11. Review and accept the End User License Agreement (EULA). Note that you 

are logged out of the appliance if you do not accept the EULA.

12. Select Help > About and confirm that the software version is listed correctly: 

Version 5.3.0. Also note the versions of the rule update and VDB on the 

Defense Center; you will need this information later.

13. Verify that the appliances in your deployment are successfully communicating 

and that there are no issues reported by the health monitor.
