2.3.3 Connecting the 3E08-04 Ethernet Switch Module
You can connect each of the four pairs of ST fiber ports on the 3E08-04 to
a 10BASE-FL port on a device such as a hub, etc. 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 3E08-04 to the receive (RX)
connector on the attached device. Similarly, the receive (RX) connector
on the 3E08-04 must be connected to the transmit (TX) connector on the
attached device (see Figure 2-3). Refer to Appendix B for cable
specifications.

NOTE
You do not need to attach terminators to unattached segments.
