Boot Authentication
Boot authentication allows you to authenticate the TeraStation while it's booting, and also prevents the TeraStation
from being used in an unauthorized or unexpected manner, such as in cases of theft.
If authentication fails, the TeraStation will stay on, but all functions and services are stopped. Users will not be able
to log in to Settings to make changes or access any shares.
Notes Before Use
• To use boot authentication, a Windows PC is necessary to serve as the authentication server.
• When activating boot authentication, the drives on the TeraStation will be formatted and all data on the drives
will be erased. Back up any important data to another device. Even though the data is deleted, the RAID array
will be kept as is.
• Assigning the TeraStation a fixed IP address is recommended for boot authentication.
• When boot authentication settings finish, export the configuration file for backup. Refer to the "Exporting
Managed TeraStations to a File" section in the Boot Authentication Tool help for the procedure.
• Boot authentication cannot be enabled if any of the following functions are enabled: drive encryption, LVM,
iSCSI, and failover. Conversely, these functions cannot be enabled while boot authentication is enabled.
Important Notice

unusable in cases of misoperation or missing important setting files. Before configuring boot authentication, back
up the data on the TeraStation by referring to the
then create a system initialization drive by referring to the
preparations, a TeraStation that is unusable may be initialized and reverted to a usable state.

• The TeraStation is unable to communicate with the authentication server due to the server crashing or it being
on another network.
• The TeraStation unit has been deleted from Boot Authentication Tool or the Boot Authentication Tool database
has been erased.
• Security level is configured to "High" and the wrong passcode is entered three times.
