Updating Your Appliances

3. Upload the update to the Defense Center by selecting System > Updates, then 

clicking Upload Update on the Product Updates tab. Browse to the update and 

click Upload.
The update is uploaded to the Defense Center.

4. Make sure that the appliances in your deployment are successfully 

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

5. Click the install icon next to the update you are installing.

The Install Update page appears.

6. Select the devices where you want to install the update.

If you are updating a stacked pair, selecting one member of the pair 

automatically selects the other. You must update members of a stacked pair 

together.

7. Click Install. Confirm that you want to install the update and reboot the 

devices.
The update process begins. You can monitor the update's progress in the 

Defense Center’s task queue (System > Monitoring > Task Status).
Note that managed devices may reboot twice during the update; this is 

expected behavior.
For Sourcefire Software for X-Series deployed inline, traffic is interrupted 

while VAPs reload.

If you encounter issues with the update (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 update. 

Instead, contact Support.

8. Select Devices > Device Management and confirm that the devices you updated 

have the correct software version: Version 5.3.0.5.

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

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

10. Reapply device configurations to all managed devices.

To reactivate a grayed-out Apply button, edit any interface in the device 

configuration, then click Save without making changes.

11. Reapply access control policies to all managed devices.

Applying an access control policy may cause a short pause in traffic flow and 

processing, and may also cause a few packets to pass uninspected. For more 

information, see the Sourcefire 3D System User Guide.
