Buffalo Technology LinkStation Pro Duo LS-WTGL/R1 - Manual (Page 8)

Power Mode
The “Power Mode” switch on the back of the unit
has three positions: “Auto”, “On”, and “Off”. The
“Auto” position automatically powers the unit on or
off based with your PC. If your PC is turned on the
LinkStation will power up; if the PC is turned off
the LinkStation will power down.
You must have installed the NAS Navigator software
on your PC for this feature to work. Otherwise, if
you move the switch to “auto”, your unit will power
down by itself and you will have to manually turn it
back on.
Also note that the unit needs to be powered on if
you want to use the Web Access feature. When
using Web Access, it is best to leave the Power
Mode switch set to “On”.
Move the switch to the “Off” position to turn the
LinkStation off. It will take about 35 seconds to
shut down. Do not unplug or interrupt power to
the unit until shutdown is complete and all LEDs
are off.
