Do not use standard telephone cables. Telephone cables will not support
Ethernet or Fast Ethernet.
Do not stretch or bend cables. Transmission errors can occur.
The cable used depends on your network speed. The switcher supports both
10Mbps(10Base-T—Ethernet)and100Mbps(100Base-T—FastEthernet),
half-duplex and full-duplex, Ethernet connections.

The Ethernet cable can be terminated as a straight-through cable or a crossover
cable and must be properly terminated for your application (figure 2-22).

•
Patch (straight) cable — Connection of the matrix 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 wired the same at both ends is
called a "straight-through" cable, because
no pin/pair assignments are swapped.
