4-Port Ethernet Network Module
Ethernet Network Module Connectors
The 1-port Ethernet network module has a single port (Ethernet port 0) for one Ethernet
connection. The 4-port Ethernet network module has ports for four Ethernet connections.
(See Figure 4-2.) Ethernet port 0 uses either the attachment unit interface (AUI) (DB-15)
connector on the right side of the module or the 10BaseT (RJ-45) connector next to it. Only
one of these connectors can be active at a time. Ethernet ports 1, 2, and 3 on the 4-port
Ethernet module use 10BaseT connectors. These ports do not provide an AUI connector.
Active ports are identified in software by port type (Ethernet), the module’s slot number,
and the port number.
On port 0, the module detects the type of network connection automatically, and you do not
need to select the media type when you configure the software. If cables are plugged into
both the AUI connector and the 10BaseT connector for the same port, the 10BaseT
connection is selected.
Connecting Ethernet Ports
On Ethernet port 0 (the right port), you can connect either the Ethernet AUI connector or
the 10BaseT connector, but not both at the same time. Ports 1, 2, and 3 provide only a
10BaseT connector.
