Enter the administrator password of the target backup device, then click Start Failover.

If the administrator password is correct, the backup TeraStation will beep.

To accept the settings from the main TeraStation, hold down the function button on the front of the backup 
TeraStation until it stops beeping.

Notes: 
•  If replication is configured for more than one folder, initialize the TeraStation before configuring failover. 
•  The main TeraStation cannot be used as the backup location for Time Machine.
•  If email notification is enabled and failover occurs, navigate to Management - Email Notification - Edit in the main 

TeraStation’s settings and click OK.

•  Ethernet frame size settings for main and failover TeraStations should be 1518 bytes. To change the Ethernet 

frame size, navigate to Network - IP Address, click the LAN port and Edit, and change the Ethernet frame size to 
“1518” bytes.

•  Files whose filenames contain more than 80 alphanumeric characters will not be backed up.
•  If a “Replication I33 ReplicateFailure” error appears on the LCD display, navigate to Backup - Replication and click 

Sync.

•  Don’t use the same TeraStation for both failover and replication, or failover and Time Machine.
•  If “Approve/Deny” window is displayed repeatedly or failover does not start, shut down both the main and 

backup TeraStations. Turn on the main TeraStation first and let it boot up. Then power up the backup TeraStation. 
Reconfigure failover.

If failover is configured, change to maintenance mode temporarily before turning off the TeraStation or updating the 
firmware. Maintenance mode can be enabled and disabled at Backup - Failover in the main TeraStation’s settings.

The “Service IP Address” will be the new address of the backup TeraStation when it takes over operation from the main 
TeraStation. If no service IP address is set or a fixed IP address is set, an attempt is made to inherit the IP address set for 
the main TeraStation. 

If network problems occur, the following messages may appear on the TeraStation’s LCD display even though neither 
TeraStation has failed. If this happens, disable and then reset failover.
•  “FailOver I49 LostMainTarget” - This message (I49) is displayed on the LCD panel of the backup TeraStation when 

operation switches from the main TeraStation to the backup TeraStation.  

•  “E27: LostBackupTarget” - This message (E27) is displayed on the LCD panel of the main TeraStation if it is no longer 

able to detect the backup TeraStation on the network.

Time Machine is a backup program included with OS X 10.5 or later. Configure your TeraStation as shown to use Time 
Machine.
