1E1R 2-Slot Network Module
The 1E1R 2-slot network module has ports for one Ethernet connection and one Token Ring
connection. (See Figure 9.)
The Ethernet port (Ethernet 0) uses either the AUI (DB-15) connector or the 10BaseT (RJ-45)
connector, but only one at a time. The Token Ring port (Token Ring 0) uses either the shielded
twisted-pair (STP) connector or the unshielded twisted-pair (UTP) connector, but only one at a time.
Ports are identified in software by port type (Ethernet or Token Ring), the module’s slot number, and
the port number.
The module detects the type of network connection automatically, and you do not need to select the
media type in software. If cables are plugged into both Ethernet ports, the 10BaseT connection is
selected.
