hi,
and welcome to the forums.
I will try to answer some of your questions:
1. shutdown
When you click the ' shutdown' button all processes on the FGT will be stopped/killed so that you can power it down afterwards. That is, ' shutdown' will
not power down the FGT. You can only power down or power up by connecting/disconnecting the power cord, there is no switch.
Yes, after connecting the power the FGT will boot and be ready after 1-2 minutes.
The configuration will be saved as soon as you press ' OK' in the dialog. You can additionally export the config as a plain text file, to keep it safe or to be able to compare configurations.
2. license and ' bundle' type
You seem to have bought a hardware bundle. In addition to the hardware (FGT) you have bought (at least) one year of manufacturer' s warranty (so called FortiCare) with hardware replacement and the right to get the newest firmware patches and releases (even if major). A ' bundle' contains one year of AV, IPS, Antispam and WF signature updates on top.
You have to register the device with it' s serial number on http://support.fortinet.com . You create a user account for this. When you enter the serial number, the period of warranty and signature updates is displayed. That' s all you have to do now.
3. FortiCloud
FC is an offer to owners of the small FGTs. It allows you to send log data and statistics to a web based storage with Fortinet, and to generate reports on those data. You have the same features on the hardware itself (Log&Report) but the reporting part is very limited, to some pie charts. The bigger FGTs use a dedicated device (FortiAnalyzer) to collect and digest log data, to be purchased separately.
4. VDOM
All FGTs come with the VDOM feature. If you activate it, you can create up to 10 virtual Fortigates on one hardware model. You switch into a VDOM and create everything like it was on a new hardware - users, admins, policies, routing vs. transparent mode etc. You can connect physical ports with virtual ports, or even two VDOMs via virtual ports.
Useful for multi-tenant hardware but rather seldomly used on models below, say, the 80C.
Hope this helps. Have fun!
