DataNET Copper Connections, Continued
DataNET Ports
See Figure 2-1. Each DataNET Hub board has nine DataNET ports. One of the DataNET ports is dedicated to ‘uplink’ connections, which will al- ways be to another DNH. The uplink port (Port 9) is an uplink port while the other ports (Port 1 through 8) are downlink ports.
Note that each of the four Downlink Port connectors contains wiring con- nections for two DataNET port channels. The connector row (above the downlink port connectors) marked Port 9 and Port 1 through Port 8 pro- vides single port connector wiring for each of the eight channels. These ports are used for making Fiber Optic connections and/or when using a DataNET Hub Signal Equalizer Board.

To make wiring easier, all board-mounted connectors are equipped with a removable plug wiring connector. Simply loosen the plug’s two top re- cessed captive screws, grasp the connector and pull it straight out from its mating connector.
Loosen the top wire retaining screws on the removed connector. Strip the insulation ¼ -inch back from each of the input leads. Insert each lead into the correct terminal. Tighten down each wire retaining screw. Plug the connector back into the board connector and tighten down the two recessed captive screws
