1 Attach one end of the twisted pair cable (STP-type only) to the copper
2 Attach the other end to a copper Ring-In port on the second module.
3 Interconnect any remaining modules using each module's
Copper lobe ports are designed to connect to end stations. They
cannot be used to interconnect modules. See Chapter 2,
Expanding the Network, for wiring specifications.
When connecting Ring-In/Ring-Out ports to a non-CoreBuilder 5000
ring, for example, ONline System Concentrator, IBM 8230 CAU, install a
Jitter Attenuator Daughter Card.
To connect Ring-In/Ring-Out ports:
Ring-Out port.
Ring-In/Ring-Out ports. To form a full ring, be sure to make connections
using both the copper Ring-In and Ring-Out ports.
When you configure ports 17 and 18 on the active per-port module or
the active per-module media module as RI/RO, install cable adapter
6200ADT-RI on the Ring-In port, port #18, which crosses over the
RX/TX wires in the cable. See Appendix A,
diagram.
To provide maximum fault tolerance for multivendor configurations:
Ensure that the local ring starts and ends with the copper Ring-In
and Ring-Out ports.
Set the correct compatibility mode using the SET TRUNK {slot}
{RING_IN/RING_OUT} COMPATIBILITY_MODE command.
