Creating an Initialization Drive
We recommend creating an initialization drive as soon as possible. This USB drive can be used to initialize the
TeraStation’s settings to its factory default values or recover the system if your TeraStation encounters an error that
prevents the unit from booting. For the detailed procedure, refer to the“Creating an Initialization Drive”subsection
in chapter 7.

Chapter 2 Configuration
Configure and manage your TeraStation using the Settings interface, accessible from a browser window. Open the
interface using the procedure below or type the TeraStation’s IP address into the URL field of your browser.
Note: Microsoft Edge, Firefox, Google Chrome, Internet Explorer 9 or later, and Safari 9 or later are supported. If you
have difficulty viewing Settings, check the following:
• If there are a large number of registered users, groups, or shared folders, use another browser instead of Internet
Explorer.
• If you have a proxy server enabled in the browser settings, configure the exception settings for Settings or disable
the proxy server.
• With Internet Explorer, set security to Local intranet. On Windows Server operating systems, higher-level security
is configured by default. Set the security to a lower level temporarily.
Configuring Settings via Setup Wizard
When you access Settings for the first time, or after initializing the TeraStation’s settings, the setup wizard will
automatically appear to help you configure several TeraStation settings, such as RAID mode and proxy server
settings.
An example screen of the setup wizard is displayed below. Step through the wizard to configure any desired
settings. If there is any setting you would like to configure later, click Skip to move to the next setup wizard screen,
or click Cancel to exit the wizard.
Example of Setup Wizard Screen
Opening Setup Wizard
You may run the setup wizard even after the initial setup or initialization. To launch the setup wizard again, follow
the procedure below.
