(Optional) Updating the Artificial Intelligence Engine Database

Preparation

Before updating the AIE database, do as follows:

• Checking the License Status

  Before updating the AIE database, ensure that the AIE license has been purchased and activated.

  To check the license status, perform the following operation:

  1. Choose System > License Management.

  2. In License Resource, search for the flow probe license. Check whether the license is activated or expired in Status.

     • If Status is Disable, activate the license. For operations, see License Management.
     • If Status indicates that the service has expired, renew the corresponding license.

• Checking the Free Space of the CF Card and Memory

  Before updating the AIE database, check whether the free space in the device CF card and memory is sufficient. The following table lists the CF card and memory space required for updating the AIE database.

  Item	CF Card Space	Memory Space
  AIE database	100 MB or higher	50 MB or higher

  Perform the following operation:

  1. Select Dashboard.
  2. In Device Information, check the available space of the CF card and memory.

• Checking the Artificial Intelligence Engine Database Version

  Check the AIE database version to determine whether the AIE database needs to be updated.

  Details are as follows:

  1. Choose System > Update Center.
  2. In Signature Database Update, view Current Version of the AIE database to be updated and determine whether it requires an update.

The AIE database can be updated in either of the following modes:

• Online update

  If the FW can communicate with the update center directly over the Internet or through a proxy server, you can update the AIE database in online mode.

  You can perform online update in either of the following modes:

  • Scheduled update

    The FW accesses the update center on a scheduled basis to check for the latest AIE database version. If the latest version is found, the FW automatically downloads the latest version and updates the local AIE database at scheduled time.

  • Immediate update

    When a new AIE database is available on the network but the scheduled update time is not reached or scheduled update is disabled on the FW, you can use the immediate update function.

    The AIE database download addresses for immediate update and scheduled update are the same, and the update processes in both modes are the same. The only difference is the update time. The immediate update can be implemented at any time.

• Local update

  When the FW is physically isolated from the Internet and no proxy server is deployed on the intranet, you can update the AIE database locally.

For details about how to upgrade the AIE database on the web UI in different scenarios, see Updating the Artificial Intelligence Engine Database.
