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.
Maintenance Mode
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.
Service IP Address
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.
Network Problems
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
