Accessing LinkStation Data from a Mac
If you don't know your LinkStation's IP address, there are
several ways to get it.
One simple method is to use the LinkStation client utility
(included on your CD), or TeraStation client utility (available
for download from www.buffalotech.com) to find your
LinkStation(s). Just click on the tab for your LinkStation
and you'll be able to read its IP address. You must have a
Windows PC running on the network to use the LinkStation or
TeraStation client utility.
If you have an all-Mac network with no Windows PCs
available, you will need to get the LinkStation's IP address
from your router's configuration utility. Many Buffalo
routers list this information on the Client Monitor page, as
shown to the right. Consult your router's documentation for
instructions on identifying client IP addresses.
