APPENDIX E: CONNECTOR PIN ASSIGNMENTS

This appendix provides information about the RJ-45 plug and the RJ-45 connector used for the NETGEAR Model FSM726S or FSM750S Managed
Stackable Switch.
RJ-45 Plug and RJ-45 Connector
In a Fast Ethernet network, it is important that all 100BASE-T certified Category 5 cabling use RJ-45 plugs. The RJ-45 plug accepts 4-pair UTP or
shielded twisted-pair (STP) 100-ohm cable and connects into the RJ-45 connector. The RJ-45 connector is used to connect stations, hubs, and
switches through UTP cable; it supports 10 Mbps, 100 Mbps, or 1000 Mbps data transmission.
Figure E-1 shows the RJ-45 plug and RJ-45 connector.
Table E-1 lists the pin assignments for the 10/100 Mbps RJ-45 plug and the RJ-45 connector.
