For first-time installation of the System, Linksys strongly recommends that you
run the Setup Wizard, which you can download from

www.linksys.com

. For

advanced users, you may follow the instructions in this Quick Installation.

NOTE:

For best results, use a

switch that offers QoS (Quality of
Service) and full wire-speed
switching. QoS enables the switch to
give top priority to voice traffic, while
full wire-speed switching lets it
forward packets as fast as your
network can deliver them. The next
best choice is a QoS (Quality of
Service) switch.

NOTE:

192.168.0.1

is the default

local IP address of the System.

NOTE:

Make sure your router will

not assign the System’s IP address to
any other device. For example, you
can assign an IP address outside of
your router’s DHCP IP address range;
however, it must be within the
router’s subnet range.

For information about IP addressing,
refer to the router’s documentation.
