All settings pertaining to the DSM-G600 proper can be found on the Tools tab. The first page of this tab is called Admin. You can change the administrator password here.
Go to the Time page to set up the device’s internal time. This can be done in three ways: using an NTP server, copying the system time from the PC, or typing it in manually. It’s good that the current time and date are also displayed on this page.
The System page allows to save/load a settings file and reboot or shut down the NAS device, etc.
The device’s firmware can be updated on the Firmware page.
The Disk Utility page is for managing disks connected to the DSM-G600. They can be formatted or scanned for errors.
The last page with settings is called E-mail Alerts. You can enter email account parameters and specify which events should trigger a notification to be sent to that email address.
