FireSIGHT System Release Notes for the 5.4 Pre-Install
Version 5.4.0 Pre-Install
First Published: November 4, 2016

These release notes provide installation instructions and a summary of the defects resolved by the FireSIGHT System Version 5.4.0 Pre-Install.
Even if you are familiar with the update and reimage process, make sure you thoroughly read and understand these release notes, which describes prerequisites, warnings, and the installation procedure.
Tip For detailed information on the FireSIGHT System, refer to the online help or download the FireSIGHT System User Guide from the Support site.

For more information, see the following sections:
Installing the Update
Before you begin the update, you must thoroughly read and understand these release notes, especially Before You Begin.
You can install Version 5.4.0 Pre-Install on Defense Centers running at least Version 5.3.1 of the FireSIGHT System.
reboot or shut down your appliances during the update until you see the login prompt. The system may appear inactive during the pre-checks portion of the update; this is expected behavior and does not require you to reboot or shut down your appliances.
When to Perform the Update
Because the update process may affect traffic inspection, traffic flow, and link state, Cisco strongly recommends you perform the update in a maintenance window or at a time when the interruption will have the least impact on your deployment.
Use the Defense Center’s web interface to perform the update. Do not install the Version 5.4.0 Pre-Install on managed devices.
Order of Installation
Update your Defense Centers to Version 5.4.0 Pre-Install and then update the system to Version 5.4.0.
Installing the Update on Paired Defense Centers
When you begin to update a Defense Center in a pair, the other Defense Center in the pair becomes the primary, if it is not already. In addition, the paired Defense Centers stop sharing configuration information; paired Defense Centers do not receive software updates as part of the regular synchronization process.
To ensure continuity of operations, do not update paired Defense Centers at the same time. First, complete the update procedure for the secondary Defense Center, then update the primary Defense Center.
After the Installation
After you perform the update on the Defense Center, you must reapply device configuration and access control policies. 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 FireSIGHT System User Guide.
There are several additional post-update steps you should take to ensure that your deployment is performing properly. These include:
- verifying that the update succeeded
- making sure that all appliances in your deployment are communicating successfully
After installing the Version 5.4.0 Pre-Install on the Defense Center and reapplying device configuration, update the system to Version 5.4.0.
The next sections include detailed instructions not only on performing the update, but also on completing any post-update steps. Make sure you complete all of the listed tasks.
Updating the Defense Center
Use the procedure in this section to update your Defense Centers, including virtual Defense Centers.
Before you update the Defense Center, reapply access control policies to any managed devices. Otherwise, the eventual update of the managed device may fail.
reboot or shut down your appliances during the update until after you see the login prompt. The system may appear inactive during the pre-checks portion of the update; this is expected behavior and does not require you to reboot or shut down your appliances.
To update a Defense Center:
Step 1 Read these release notes and complete any required pre-update tasks.
For more information, see Before You Begin.
Step 2 Download the update from the Support site:
Note Download the update directly from the Support site. If you transfer an update file by email, it may become corrupted.
Step 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. The web interface shows the type of update you uploaded, its version number, and the date and time it was generated.
Step 4 Make sure that the appliances in your deployment are successfully communicating and that there are no issues reported by the health monitor.
Step 5 View the task queue ( System > Monitoring > Task Status) to make sure that there are no tasks in progress.
You must wait until any long-running tasks are complete before you begin the update. 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.
Step 6 Select System > Updates.
The Product Updates tab appears.
Step 7 Click the install icon next to the update you uploaded.
The Install Update page appears.
Step 8 Select the Defense Center and click Install. Confirm that you want to install.
Note The Defense Center does not reboot.
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 running.
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
restart the update. Instead, contact Support.
use the web interface to perform any other tasks until the update completes. Before the update 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 update is still running, do
use the web interface until the update completes. 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
restart the update. Instead, contact Support.
Step 9 After the update finishes, clear your browser cache and force a reload of the browser. Otherwise, the user interface may exhibit unexpected behavior.
Step 10 Log into the Defense Center.
Step 11 Select Help > About and confirm that the software version listed is the version you updated from.
Step 12 Verify that the appliances in your deployment are successfully communicating and that there are no issues reported by the health monitor.
Note Cisco strongly recommends reapplying device configuration after installing the Version 5.4.0 Pre-Install.
