 Terminator

The BNC port on the Model SW502 switch, together with the BNC T-connector and the 50 

Ω

terminator are used for connection to a thin coaxial segment. A thin coaxial Ethernet segment supports
10 Mbps data transmission. For information on connecting through the BNC port, refer to Chapter 3,
“Installation,” and Appendix C, “Cabling Specifications.”
