Ethernet Management STP Ports
MIOs/UMIOs support two autosensing RJ45 10/100/1000Base-T (IEEE 802.3ab) Ethernet, shielded twisted-pair (STP)
copper interfaces (logical Ports 1 and 2) for out-of-band system management access to the CLI.
copper interfaces (logical Ports 1 and 2) for out-of-band system management access to the CLI.
Important:
To comply with GR-1089 intra-building, lightning-immunity requirements and FCC Radiated
Emissions Criteria, you must use STP cable and ensure that it is properly terminated at both ends.
Caution:
The 1000Base-T management ports are suitable for connection to intra-building or unexposed wiring
or cabling only. These intra-building ports MUST NOT be metallically connected to interfaces that connect to the
outside plant (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, Issue 5) 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.

The ports support MDI and MDI-X connectors. Ethernet ports normally use MDI connectors and Ethernet ports on a
hub normally use MDI-X connectors.

An Ethernet straight-through cable is used to connect an MDI to an MDI-X port. A cross-over cable is used to connect
an MDI to an MDI port, or an MDI-X to an MDI-X port.
