Switch Ports and Network Cables
This appendix includes switch connector information and network cable
information for cables that should be used with the SMC6624M switch,
including minimum pin-out information and specifications for twisted-pair
cables.
N o t e
Incorrectly wired cabling is the most common cause of problems for LAN
communications. SMC recommends that you work with a qualified LAN cable
installer for assistance with your cabling requirements.
Switch Ports
Twisted Pair
■
The fixed RJ-45 10/100Base-TX ports on the switches and the RJ-45
connector on the 100/1000Base-T module accept 100-ohm unshielded and
shielded twisted-pair cable with RJ-45 connectors as described on the
next page.
Fiber-Optic
■
The SC-type connector port on the 100Base-FX module transmits at 1300
nm wavelength, and accepts the multimode fiber-optic cables for 100Base-
FX described on the next page.
■
The SC-type connector port on the 1000Base-SX module transmits at 850
nm wavelength, and accepts the multimode fiber-optic cables for
1000Base-SX described on the next page.
■
The SC-type connector port on the 1000Base-LX module transmits at 1300
nm wavelength, and accepts the single mode or multimode fiber-optic
cables for 1000Base-LX described on the next page.
