Buffalo terastation 3000, User Manual

Page: 100 / 232

When failover, the backup TeraStation will take over the hostname and IP address of the main TeraStation unless the
IP conflict is detected. If you want to assign different IP address to the backup TeraStation after failover, configure
the “service IP address”. The service IP address will be a new address of the backup TeraStation when it takes over
operation from the TeraStation.
Using the Same LAN Port for Both Failover and Connecting to the Network
Using this setup, if the main TeraStation fails, the backup TeraStation will replace it completely. The backup
TeraStation will be updated over normal network traffic.

Using Different LAN Ports for Connecting to the Network and Failover
With this setup, the backup TeraStation and main TeraStation are connected by a second Ethernet cable connecting
their LAN 2 ports. Updating is done over this dedicated network path, so updates are quicker and don’t interfere
with normal network traffic.
