Chapter 2 Getting Started

To turn off the TeraStation, press and hold down the power button for three seconds. When the power LED turns off,
the shutdown process is finished.
Don’t unplug the power cable without powering the TeraStation off first.
Note: Do not disconnect or reconnect the internal drives while turning the TeraStation on or off.
You can also shut down or restart the TeraStation remotely from Settings. For the detailed procedure, refer to the
“Shutting Down or Restarting the TeraStation from Settings”section below.
Creating a USB Initialization Drive
We recommend creating a USB 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 a USB Initialization Drive”
subsection in chapter 8.
Accessing Settings
Configure and manage your TeraStation using the Settings interface, accessible from a browser window. Open
the interface using the appropriate 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.
Opening Settings
