Making Ethernet Connections - Cisco EF4116 Hardware Installation And Maintenance Manual

Making Ethernet Connections

Ethernet network processor modules contain both Ethernet AUI connectors and 10BaseT
connectors. Dual Ethernet modules contain two of each type of connector interface.
For dual-port Ethernet modules (see Figure 3-2), connect either the Ethernet AUI connector or the
10BaseT connector on a specific Ethernet port, but not both connectors on the same port. For
single-port Ethernet modules (see Figure 3-3), connect either the Ethernet AUI or the 10BaseT
connector, but not both on the same module.
In Figure 3-2, the configuration on the left, showing two network connections attached to Port 0, is
unsupported; the configuration on the right, which shows two network connections, one to Port 0
and one to Port 1, is supported.
Figure 3-2
In Figure 3-3, the single-port Ethernet module on the left shows an unsupported configuration of two
network connections going to two connectors on the same port; the module on the right shows a
supported connection with a single 10BaseT cable connecting to a single connector on the port.
