Caution:

- Please consult your local technical support representative if you experience any problems caused by this firmware update.
- Do not turn the unit off until the update is finished. It will take several minutes. You will receive a message when the update is finished.
- USB drives are not mounted automatically after a firmware update. To mount them, unplug and then reconnect them.

How to Use the Updater:

1. Connect the TeraStation properly and configure the TeraStation and a computer to run the updater on the same network subnet. The subnet masks should be the same and the first three numbers of the IP addresses should be the same. The last number of the IP addresses should be different.
For example, if the IP address and subnet mask of the computer are
" 192.168.0.10 , 255.255.255.0 "
and the IP address and subnet mask of the TeraStation are
" 192.168.1.150 , 255.255.255.0 "
then the updater will _not_ work properly.
In this case, reconfigure the TeraStation's IP address and subnet mask to
" 192.168.0.150 , 255.255.255.0 ".
Then they will be on the same subnet and the updater will work properly.
2. Close all applications. Also, stop or exit any firewall software.
3. Extract the downloaded file and run "TSUpdater.exe". When a TeraStation is detected, an update window will open.
4. Select the TeraStation to update if multiple TeraStation are connected.
5. Click "Update" and enter the TeraStation's admin password.
6. Click "OK".
7. Transferring and updating the firmware will start. Wait until it finishes. The info LED will blink during the update.
8. When the update finishes, a message will be displayed.

About Network-Attached Storage Updates:

Upgrading the Network-Attached Storage (NAS) firmware can improve the system's overall performance, stability, and security by adding various fixes for related issues, enhancing existing features (or adding support for new ones), or updating different applications.

Due to the high number of NAS manufacturers, as well as network storage types, installing a new firmware might not be always as easy as it appears – and not too safe either. Failing to perform a software update can cause serious malfunctions to the network storage.

So, before you even consider applying this release, carefully read the installation guide and initiate the process only when you have understood and completely familiarized yourself with all the steps.

Moreover, it would be best if you take into account using a UPS unit (Uninterruptible Power Supply) to perform this task, because no power disruption should affect the upgrade.

With all these aspects in mind, after you have read the installation guide, click the download button to apply this firmware version to your NAS. Remember to check back with our website in order to stay up to speed with the latest releases.
