Cables and connectors
31
The RJ-45 port on computer and workstation adapter cards, which
connects them to the network, is referred to as the MDI-II
(straight-through) port. If you are connecting an MDI-X port at
one end and an MDI-II port at the other end—that is, connecting a
hub or switch to a station—a straight-through cable should be used.
To connect MDI-X ports at both ends—connecting two hubs for
instance—use a crossover cable.
The uplink port (port 1) can be designated as a MDI-II
or MDI-X port, allowing you to connect both straight-
through or cross-over cables to it.
Patch panels and cables
If you installed patch panels to interconnect hubs and switches in
different floors of a building, you also need to use Category 3 or
Category 5 UTP patch cables for 10BASE-T connections and
Category 5 UTP patch cables for 100BASE-TX.
To wire patch panels, use patch cables that have male RJ-45 con-
nectors. (You will need to use two UTP patch cables.)
Fiber-optic cables
To connect fiber-optic cables to the ports on the FSW-1607/
2407TFX ’s 100BASE-FX switch module, you must use 130 nm
wavelength, multimode cable conforming to the ISO/IEC 793-2
type B1 and ITU-T G.652 standards. SC-type connectors must al-
so be used with the cables.
