Connecting a Management Ethernet Cable
When using the 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 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.
The intra-building port(s) of the equipment or subassembly must not be metallically connected to interfaces
that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces
only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require isolation from the exposed
OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these
interfaces metallically to OSP wiring. Statement 7005
