A TNAS may be installed with or without a hard drive, since different models are available for purchase. If
you purchase a TNAS without a hard drive, you should purchase a hard drive separately. Only after hard
drives have been installed and initialised can the TNAS be used.
Please refer to the “Quick Installation Guide” to complete hard drive installation.
Therefore, to complete the connection, please follow the instructions below:
Step 1:
Connect TNAS to the network using a network cable. The possible network devices that TNAS can connect
to can be routers, hubs, network switching.
Step 2:
Connect TNAS to a power supply using the supplied power adapter (Warning: Please do not use a third-party
power adapter. If you do, the device may sustain severe damage, and in extreme cases, damage to the
physical body can occur).
Step 3:
Press the power button to power on TNAS.
Step 4:
If the hardware indicator is always red, this indicates that the hard drive is functioning abnormally. The
hard drive may be damaged, or the hard drive may not be compatible with the TNAS device. If this
happens, please re-install or replace the hard drive and try again.
Step 5:
If the hard drive indicators and network indicators display a normal connection, your TNAS hardware is
ready.
TNAS should be installed with hard drives of the following type: firstly, 2.5/3.5 inch SATA hard drive; or
secondly, 2.5 SATA SSDs. TNAS is a durable storage device, which means that in order to operate for long
periods of time, high-quality hard drives are required. Therefore, please visit TerraMaster’s official
website to read our “Hard Drive Compatibility” guide, and then select the correct hard drive for your
TNAS.

Newly purchased TNAS devices must be initialised prior to use. In the process of initialisation, TOS will be
installed onto your TNAS. Please see the section on “Initialisation” for an operation guide to TOS

Step 3: Hard Drive Detection
If the installed hard drive is detected by TNAS, bootstrap initialisation will automatically proceed to the next
step. If the hard drive is not installed, please install the hard drive and click “Recheck”. Since TNAS
supports hard drive hot swap, the hard drive can be directly installed without having to turn the power off.
Step 4: Hard Drive Check-Up
Your TNAS will assess the health status of the hard drive. If the health status is good, please click “Next”. If
the test results indicate a risk, we recommend that you replace the abnormal hard drive.

After TOS installation is complete, TNAS will take several minutes to restart. Please wait patiently for this
process to finish. Once TNAS has restarted successfully, you will be guided to the next step.
Step 6: Basic Settings
Complete the basic settings for TNAS according to the instructions. This will involve setting a password,
inputting device name, selecting your time zone, and clicking “Next”.
Step 5: Install TOS
Follow the page prompts to install TOS. If your TNAS is connected to the Internet, we recommend that you
choose the “Online Install” option. Otherwise, choose the “Manual Install” option. If you select
“Manual Install”, please visit TerraMaster's website to download the TOS software package from the
“Download” before you process the installation.

Step 7: Administrator Settings
Please set the administrator password and complete the administrator security mailbox (this is used for
administrator authentication) (Note: It is extremely important that you take care when completing this step.
If the administrator loses their password, completing the administrator security mailbox will allow them to
reset their password). Afterwards, click “Send Code”, and the security mailbox will receive an email with a
verification code. Please log in to the security mailbox in order to obtain your code, and then complete the
administrator settings.
Step 8: Create RAID
Please select the RAID type, and then select the hard drive you intend to use to create RAID and click Confirm.
There are two file systems to choose from: EXT 4 and Btrfs. The system default file format is Btrfs. If you need
to modify the file format, go to the control panel of TOS. When the RAID has been created, hard drive
formatting will occur. Therefore, please back your data up in advance (Note: Please take a moment to wait for
hard drive formatting to finish. When you see “Congratulations! Initialisation is complete!”, this indicates
that your TNAS is ready for use).

As a final note, if you receive an error message stating that the number of hard drives you have picked does
not match the RAID type you have selected, please reset your settings.
This section provides a quick overview of your TNAS device’s core functions.
5. Getting Started

To store files to TNAS, the most convenient and efficient way is to use the Samba file service (for Windows OS
users) or the AFS file service (for Mac OS Users).
To use these services, select your TNAS from the menu in TNAS PC and click “File Browser”. Then, enter
your username and password, and you will be able to access the file browsing page. There, you can copy,
delete, and edit your files. This feature is used on Windows OS and Mac OS in the same way.
For added efficiency, you can also map your drive to display frequently accessed folders or to create quick
links. This method is only applicable to windows OS users, Mac OS users create shortcuts in a slightly different
way, please visit the TOS Help for more details.
If you need to use the advanced settings features (e.g., to create users, manage permissions, monitor system
resources, or to install applications), please log in to TOS. Only users with administrator privileges can use
TOS’s advanced features.
