Ethernet Connection
PRELIMINARY
Ethernet Link
The rear panel Ethernet connector on the 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 (figure A-1).
• Crossover cable — Direct connection between the computer and
the switcher.
• Patch (straight-through) cable — Connection of the 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 addre
To access the switcher via the LAN port, you need the IP address of 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
switcher.
