Appendix C
Cables and connectors
Cables and connectors
This appendix provides specifications and pin-out information for
cables to be used with FSW-1607/2407TFX. The importance of
this appendix can not be over-emphasized as many problems with
LAN communications can be traced back to incorrectly wired ca-
bling.
Twisted-pair cables and connectors
Fast Ethernet network connections require twisted pair cables as
specified in the IEEE 802.3u standard for 100BASE-TX. Twisted
pair cables are available unshielded (UTP) or shielded (STP).
UTP is the most common. Both UTP and STP come in stranded
and solid wire varieties and should be Underwriters Laboratories
(UL) or Electronic Testing Laboratories (ETL) certified.
If you are setting up your network in a factory or around
heavy machinery, use STP cables. The shield protects
against excessive electromagnetic interference found in
such noisy environments.
