Connecting to a Keyboard and Mouse
Use the 2 USB hosts located at the front side of unit to connect a keyboard and mouse to the
IA261/262.
Connecting to the Network
Connect one end of the Ethernet cable to one of the IA261/262’s 10/100M Ethernet ports (8-pin
RJ45) and the other end of the cable to the Ethernet network. If the cable is properly connected,
the IA261/262 will indicate a valid connection to the Ethernet in the following ways:
The LED indicator in the lower right corner glows
a solid green color when the cable is properly
connected to a 100 Mbps Ethernet network. The
LED will flash on and off when Ethernet packets
are being transmitted or received.
The LED indicator in the lower left corner glows a
