Port and Cable Assignments
RJ-45 Port Description
RJ-45 station ports (MDI-X) can be attached to
any devices which use a standard network
interface (e.g., a workstation, server, bridge or
router). Similar networking devices (e.g., another
hub or switch) can be cascaded by connecting the
(MDI) daisy-chain port on the hub to an (MDI-X) RJ-45 port on the other device.
Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45
connections: 100
Ω
Category 3, 4 or 5 cable for 10 Mbps connections or 100
Ω
Category 5 cable for 100 Mbps connections. Also be sure that the length of any
twisted-pair connection does not exceed 100 meters (328 feet).
