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
10Mbps(10Base-T—Ethernet)and100Mbps(100Base-T—FastEthernet),
half-duplex and full-duplex, Ethernet connections.
• 10Base-TEthernetrequiresCAT3UTPorSTPcableatminimum.
• 100Base-TFastEthernetrequiresCAT5eUTPorSTPcableatminimum.
The Ethernet cable can be terminated as a straight-through cable or a crossover
cable and must be properly terminated for your application (figure 2-21).
