Network Module Connectors
Blank WAN Interface Card Panels
If the 2-slot network module is configured with fewer than two WAN interface cards, make sure that
blank panels fill the open base module slots to provide proper airflow. (See Figure 6.)

Network Module Connectors
The number and type of connectors on a 2-slot network module depend on the type of module.
1E 2-Slot Network Module
The 1E 2-slot network module has one Ethernet attachment unit interface (AUI) DB-15 connector
and one 10BaseT RJ-45 connector. (See Figure 7.) Only one of these two connectors can be active
at a time. The active port is identified in software by port type (Ethernet), the module's slot number,
and port number 0.
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 ports, the 10BaseT connection is selected.

2E 2-Slot Network Module
The 2E 2-slot network module has ports for two Ethernet connections. (See Figure 8.)
Ethernet port 0 uses either the AUI (DB-15) connector on the right or the 10BaseT (RJ-45) connector
in the center, but only one at a time. Ethernet port 1 uses the 10BaseT connector on the left. This port
does not provide an AUI connector. Ports are identified in software by port type (Ethernet), 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 ports, the 10BaseT connection is selected.
