Ethernet Port Connections
I/O controllers have the possibility of one or two types of Ethernet connections: MII connections and RJ-45 connections for
10/100-Mbps operation. For more information about Ethernet ports, see the online Cisco 7206 Installation and Configuration
Guide.
MII Connections
Attach the MII cable to the MII port and tighten the knurled thumbscrews on the cable to the jackscrews on the port.
RJ-45 Connections
Warning
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage
(TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports
both use RJ-45 connectors. Use caution when connecting cables.
To identify the RJ-45 cable type, hold the two ends of the cable next to each other so you can see the colored wires inside the
ends. The straight-through wire type has colored wires in the same sequence at both ends.
In the crossover wire type, the first colored wire at the far left is the third colored wire at the other end. The second colored
wire at the far left is the sixth colored wire at the other end.
Attach any RJ-45 Ethernet cables to the appropriate connector.
Port Adapter Cable Connections
The instructions for connecting the cables for each port adapter installed in the Cisco 7206 router is in the respective online
note for each port adapter. The documents are available on the Documentation CD-ROM and on Cisco.com at
