How can you manually renew the license for a ProxyAV appliance?
Anti-virus scanning services cannot begin without a valid license installed on the AV appliance from one or more AV vendors. License Key files are obtained from the Network Protection Licensing Portal (NPLP), which requires your Symantec credentials for access.
To acquire a license:
Log into the Network Protection Licensing Portal (NPLP).
Select Symantec AV from the menu on your left.
Select Activate License from the menu on your left.
Enter the Hardware Serial# (which is on the Management Console home page) and the Activation code that you received in an email. If you don't have an activation code or are having problems entering your activation code, you can skip the activation process and retrieve the license to proceed with manual installation.
Accept the EULA.
To activate your license, click the Update license button in the License Key Automatic Installation section in the AV appliance. Also, check the Use Auto Update check box.
NOTE: If you already have an AV appliance and subscription number, you can enter that subscription number in place of the activation code when you receive a new AV appliance.
