Chapter 10 Install and System Administration for FortiOS 5.0 : Central management : Configuration through FortiManager
  
Configuration through FortiManager
With the FortiManager system, you can monitor and configure multiple FortiGate units from one location and log in. Using the FortiManager’s Device Manager, you can view the FortiGate units and make the usual configuration updates and changes, without having to log in and out of multiple FortiGate units.
FortiManager enables you to complete the configuration, by going to the Device Manager, selecting the FortiGate unit and using the same menu structure and pages as you would see in the FortiGate web-based manager. All changes to the FortiGate configuration are stored locally on the FortiManager unit until you synchronize with the FortiGate unit.
When a FortiGate unit is under control of a FortiManager system, administrators will not be able to change the configuration using the FortiGate. When trying to change options, the unit displays a message that it is configured through FortiManager, and any changes may be reverted.
