DataNET Copper Connections, Continued
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.
PORT INTERFACE
CONNECTORS
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
