RJ-45 connector
The RJ-45 connector is used to connect with a hub or switch, RJ-45 regular ports
(MDI) can be attached to any devices which use a standard network interface (e.g., a
workstation, server, bridge or router). RJ-45 up-link ports (MDI) can be cascaded to a sta-
tion port on similar networking devices (e.g., another switch or hub). Use unshielded twist-
ed-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100½ Category
3, 4 or 5 cable for 10 Mbps connections or 100½ Category 5 cable for 100 Mbps connec-
tions. Also be sure that the length of any twisted-pair connection does not exceed 100
meters (328 feet).
Schematics for straight cable are shown as below.
