Preparing to Connect to a Network
When setting up your RPM-XF in the Cisco MGX 8850, consider distance limitations and potential
electromagnetic interference (EMI) as defined by the EIA.
The Fast Ethernet, console, and auxiliary ports contain safety extra-low voltage (SELV) circuits.
Note
Connect them only to SELV-circuit equipment.
Ethernet Connection
The Ethernet ports located on the MGX-XF-UI or MGX-XF-UI/B back card support IEEE Ethernet
standard 802.3 and Fast Ethernet standard 802.3u. The back card implementation supports the following
connections:
•
•
The cables required to connect the MGX-XF-UI or MGX-XF-UI/B Fast Ethernet ports to an Ethernet
network are not included. For cable ordering information, contact customer service.
For cable and port pinouts, see
Console and Auxiliary Ports
The MGX-XF-UI and MGX-XF-UI/B include asynchronous serial console and auxiliary ports. The
console and auxiliary ports provide local administrative access to the RPM-XF. This section discusses
important cabling information to consider before connecting a console terminal to the console port or
the auxiliary port.

10BASE-T— Ethernet on unshielded twisted-pair (UTP) cable. The maximum segment distance is
328 feet (100 meters). UTP cables look like wiring used for ordinary telephones; however, UTP
cables meet certain electrical standards that telephone cables do not. The 10BASE-T Ethernet
operates at 10Mbs and can be connected through the RJ-45 connector.
100BASE-TX—100BASE-T Ethernet, half and full duplex over Category 5 UTP, Electronics
Industry Association and Telecommunications Industry Association [EIA/TIA]-568-compliant
cable. The 100BASE-T Ethernet operates at 100Mbs and can be connected through the RJ-45
connector.
