UTP Ethernet/10Base-T Connectivity
Ethernet connectivity includes twisted pair (UTP) cabling (below), and fiber-optic cabling (page 9).
Twisted Pair Cabling
The Ethernet module for the Switch 2000 has 10Base-T ports that operate as MDI-X ports, and a slot to install a
10Base-T transceiver that operates as an MDI port.
•
MDI-X Operation: The four 10Base-T ports built into the module are designed for MDI-X operation (that is, for
connecting end nodes to the switch). Thus, if you connect any of these ports to an MDI-X port on another device,
use a “crossover” cable. But if the connection is to an MDI port, use a “straight-through” cable.
•
MDI Operation: An optional 10Base-T transceiver in the transceiver slot operates in MDI mode (that is, for con-
necting hubs or other switches to the Switch 2000). In this case, use a “straight-through” cable to connect the
transceiver to an MDI-X port on another device, or a “crossover cable” to connect the transceiver to another trans-
ceiver or other MDI port on another device.
Note that if the connection from the 10Base-T transceiver is to another HP 10Base-T transceiver (requiring a cross-
over cable), the “long cable” option can be set on both transceivers, allowing the connection to be up to 200 meters.
See the transceiver documentation for more information. (For more on straight-through and crossover cables, see
appendix A, “Cables and Connectors”, in the HP AdvanceStack Switch 2000 Installation Guide.)
