Connecting Ethernet Repeater Port UTP Cables

To connect unshielded twisted-pair (UTP) cables to the front panel 10Base-T repeater ports, attach the UTP cables to the front-panel RJ-45 connectors (Ethernet Repeater Ports 1-8), as shown in Figure 2-8.

Figure 2-8. Connecting Repeater UTP Cables

Using the MDI/MDI-X Switch

The ANH-8/DC front panel includes an external MDI/MDI-X switch (Figure 2-9) that allows you to change transmit and receive signals for 10Base-T repeater Port 1 from normal repeater input mode (media-dependent interface with crossover, or MDI-X) to repeater cascade out (media-dependent interface, or MDI) configuration. In MDI-X mode, transmit and receive signal connections are reversed; in MDI mode, the port transmits and receives straight-through signals

With a standard (straight-through) UTP cable in Port 1, press the switch in for MDI operation.

With a crossover cable in Port 1, keep the switch out for MDI-X operation.
