Attaching 4R Port Adapter Interface Cables

The Token Ring ports on the 4R port adapter run at either 4- or 16 Mbps. You need one Token Ring interface cable for each 4R port adapter interface you want to use. Token Ring interface cables are not available from Cisco Systems, but are commercially available through outside cable vendors.

Following is the procedure for attaching Token Ring cables to the 4R port adapter:

Step 1 Determine which 4R port adapter ports you want to use.

Note The IBM Token Ring specifies a star topology, with all end stations connected through a device called an MSAU. IEEE 802.5 does not specify any topology, although most implementations are based on a star configuration with end stations attached to a device called an MAU. Also, IBM Token Ring specifies twisted-pair cabling, whereas IEEE 802.5 does not specify media type. Most Token Ring networks use shielded twisted-pair (STP) cabling; however, some networks that operate at 4 Mbps use UTP cable.
