2.2.2 Connecting the 3H08-04 FE Switch Module
You can connect each of the four pairs of ST fiber ports on the 3H08-04 to
a 100BASE-FX port on a device such as a hub, using fiber optic cable.
Each fiber segment has a pair of female ST connectors clearly marked as
“RX” and “TX.”
Attach the transmit (TX) connector on the 3H08-04 to the receive (RX)
connector on the attached device. Similarly, you must then connect the
receive (RX) connector on the 3H08-04 to the transmit (TX) connector on
the attached device (see Figure 2-2). For more information on cable
specifications, see Appendix B.
