26. uorescent lights transformers and other high power devices to avoid possible interference e Do Not Run Cables Longer Than The Maximum Length The maximum cable lengths includes all patch cords from node to wall plug and patch panel to hubs KNE24TP RS User s Guide Rev A01 Kingston Technology Company 18 Appendix B Cabling Guidelines Cable Wiring Standards There are two governmental agencies the Electronic Industry Association EIA and the Telecommunications Industry Association TIA which set the standard for all cable wiring requirements for commercial buildings With the advent of 100Mb s networking products it is best to use higher quality CAT 5 cables like Belden or Helix as well as CAT 5 compliant patch panels patch cables and connectors while following the EIA TIA wiring standards 100 Q UTP CAT 5 type cables use 4 pair UTP wiring Refer to the illustrations below for 4 pair wiring using either T568A Fig B 4 or T568B Fig B 5 wiring standards Both T568A and T568B wiring is compatible with 10BASE T and 100BASE TX and require no special configurations but stick to one wiring standard If your building is wired for T568A any changes or additions must be done with the T568A wiring scheme Mixing the T568A and T568B wiring schemes will not work Pair 3 12345678 12345678 T568A T568B Fig B 4 4 Pair T568A Wiring Fig B 5 4 Pair T568B Wiring em Pare Sean eT Fats e MN White Blue Green White Blue
