TeraStation Layout
UPS interface – An Uninterruptable Power Supply can use this serial
port to safely shut down your TeraStation in the event of a power failure.
This interface is non-LPS. DP-1, DP-1P, DP-2, or DP-2P cables may be
used to connect to the UPS. The TeraStation Pro also supports many USB
Uninterruptable Power Supplies.
10/100/1000 Mbps Ethernet Port – Use this port to connect your
TeraStation to a switch, a router, or another computer. The port is
autosensing, so either a conventional Ethernet cable or a crossover
Ethernet cable may be used.
USB Ports – TeraStation offers two USB 2.0/1.1 ports for adding external
drives or UPSs. Please see the TeraStation Expansion section on page 20
to learn more about using TeraStation's USB Ports.
