Chapter 1 What’s New for FortiOS 5.2.1 : Managing Devices : Endpoint Licenses
  
Endpoint Licenses
New Endpoint licenses are now available in FortiOS 5.2. Information about the status of the current license can be found in the FortiClient section of the License Information widget.
The following licenses will be available:
Desktop models and FortiGate-VM00: 200 clients
1U models, FortiGate-VM01 and FortiGate-VM02: 2,000 clients
2U models and FortiGate-VM04: 8,000 clients
3U models, FortiGate-ATCA, and FortiGate-VM08: 20,000 clients
Because the new licenses are for one year, the activation method has changed. New licenses are purchased similarly to a FortiGuard service, with no further registration of the license required. The device can then be registered with the FortiGate unit.
If the device does not have access to Internet, you can download the license key from support site and manually upload it to your FortiGate. The license will be for that specific device and will have an license expiry date.
While the older licenses from FortiOS 5.0 will still be supported, they will have the following limitations:
The On-Net Status feature will not be supported.
Logging options will only appear in the CLI.
FortiAnalyzer Support for logging and reporting will be limited.
You will not be able to enter any v5.0 license keys.
