Screen Resolution Compatibility

Cisco recommends selecting a screen resolution that is at least 1280 pixels wide. The user interface is 
compatible with lower resolutions, but a higher resolution optimizes the display.

If you need to return your appliance to a previous release of the FireSIGHT System for any reason, 
contact Support for more information.

Before you begin the update, you must thoroughly read and understand these release notes, especially 

.

To update appliances running at least Version 5.3.1 of the FireSIGHT System to Version 5.3.1.1, see the 
guidelines and procedures outlined below:

This update is not supported on physical or virtual managed devices or Sourcefire Software for X-Series. 

Do not 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.

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. Update the Defense Center first, then use 
it to update the devices it manages.

Update your Defense Centers before updating the devices they manage.
