Ethernet
Connection
This section provides a high level discussion of the Ethernet connection to the switcher and
a primer on the subject of subnetting. Topics that are covered, include:
• Ethernet Link
• Subnetting — A Primer
Ethernet Link
The rear panel Ethernet connector on the CrossPoint or MAV Plus switcher can be
connected to an Ethernet LAN or WAN. This connection makes SIS control of the switcher
possible using a computer connected to the same LAN.
Ethernet Connection
The Ethernet cable can be terminated as a straight-through cable or a crossover cable and
must be properly terminated for your application (see figure 101).
• Crossover cable — Direct connection between the computer and the
CrossPoint or MAV Plus switcher
• Patch (straight-through) cable — Connection of the CrossPoint or MAV Plus
switcher to an Ethernet LAN
A cable that is wired as T568A at one end
and T568B at the other (Tx and Rx pairs
reversed) is a "crossover" cable.
A cable that is wired the same at both ends is
called a "straight-through" cable, because
no pin/pair assignments are swapped.

Default IP Address
To access the CrossPoint or MAV Plus switcher via the LAN port, you need the IP address
of the switcher. If the address has been changed to an address comprised of words and
characters, you can determine the actual numeric IP address using the ping utility. If the
address has not been changed, the factory-specified default is 192.168.254.254.
Ping can also be used to test the Ethernet link to the CrossPoint or MAV Plus switcher.
