Connector Pin Assignments

This appendix provides information about the RJ-45 connector used for the NETGEAR 
Model SW108 Ethernet switch.

RJ-45 Plug and vista RJ-45 Connector

The RJ-45 plug accepts 4-pair unshielded twisted pair (UTP) or shielded twisted pair (STP) 
100 

 cable and connects into the vista RJ-45 connector. 

The vista RJ-45 connector (also referred to as a 10 Mbps port) is used to connect stations, hubs, 
and switches through UTP cable and supports 10 Mbps data transmission. 

The RJ-45 plug and vista RJ-45 connector are both illustrated in Figure B-1.
