Connect the Fast Ethernet Management Port Cable
Figure 11 Installing the Fast Ethernet Management Port Cable
When using the Fast Ethernet Management port in the default mode (speed-auto and duplex-auto) the port operates in
auto-MDI/MDI-X mode. The port automatically provides the correct signal connectivity through the Auto-MDI/MDI-X feature.
The port automatically senses a crossover or straight-through cable and adapts to it.
However, when the Fast Ethernet Management port is configured to a fixed speed (10 or 100 Mbps) through command-line
interface (CLI) commands, the port is forced to MDI mode.
When in a fixed-speed configuration and MDI mode:
• Use a crossover cable to connect to an MDI port
• Use a straight-through cable to connect to an MDI-X port
Connect Native Gigabit Ethernet Cables
The Cisco 7201 router native Gigabit Ethernet ports use either optical fiber or RJ-45 Ethernet cables. For installation
information see:
• Install the SFP Module Optical Fiber Cables, page 15
• Install the Native Gigabit RJ-45 Ethernet Cables, page 18
The SFP port is a 1000-Mbps optical interface in the form of an LC-type duplex port that supports IEEE 802.3z interfaces
compliant with the 1000BASEX standard. (See Figure 13.)
Appendix A, “Specifications” of the online Cisco 7201 Installation and Configuration Guide, provides cabling specifications
and configuration information for the SFP modules that you install in the Gigabit Ethernet SFP ports.
Warning
Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid
exposure to laser radiation and do not stare into open apertures.
