IMPORTANT: Tableau strongly recommends that the T35i be on a
dedicated power supply lead. Switching the T35i on/off can lead to
large current/voltage surges which can interrupt the operation of
other devices which share a power supply connection with the T35i.
CONFIGURATION SWITCHES
The following table summarizes the function of the four position DIP switch.

In most situations, Windows XP handles READ-ONLY
bridges correctly and will work optimally when leaving
switches 2 and 3 in the OFF (default) state.
However, Tableau has seen cases where Windows XP will
not allow a user to access a READ-ONLY partition. If you
encounter a situation in which Windows XP reports that a
volume is "write protected" and will not allow you to
access the partition, then try the switch setting
recommended for Windows 2000, below.

Windows 2000 does not mount NTFS volumes correctly
