Preparation

This section describes preparations for signature database updates.

Checking the License Status

Before updating a signature database, ensure that the license for the update service has been purchased and activated.

To check the license status, perform the following operation:

Choose System > License Management.
In License Resource, search for the signature database to be updated. 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 a signature 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 various signature databases.
