Cables and Termination
NOTE: To fully comply with EMI (electro-magnetic interference)
specifications, the use of shielded or screened cables may be required.
“Shielded” describes IBM-defined cables used with the DB-9 connector.
“Screened” describes cables that are electrically similar to Category 4
UTP (Unshielded Twisted Pair), but with an added shield or screen.
10Base-T or 100Base-Tx (Twisted Pair)
100Base-Tx requires Category 5 (100-Ohm UTP) cabling.
Do not use “silver satin” telephone extension cables for 10Base-T
networks, either as drop cords or as patch cables in the wiring
closet. (Silver satin cables are flat, usually silver or gray, with
28-gauge stranded or tinsel conductors.) Do not use shielded
twisted pair cable intended for IBM Token Ring networks or voice-
grade (level 1 or 2) unshielded twisted pair cable for wiring runs.
These cables do not meet the requirements for 10Base-T and will
lead to unreliable operation.
