Installation

Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (e.g., the power cord or network cabling), test them in an alternate environment where you are sure that all the other components are functioning properly.

Port and Cable Assignments

RJ-45 Port Description

RJ-45 (MDI-X) station ports can be attached to any devices which use a standard network interface (e.g., a workstation, server, bridge or router). RJ-45 (MDI) daisy- chain ports can be cascaded to a station port on similar networking devices (e.g., another hub or switch). Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100Ω Category 3, 4 or 5 cable for 10 Mbps connections or 100Ω 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).
