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. Port adapters have a handle attached (see ), but this handle is not shown in to allow a full view of detail on the 4R port adapter’s faceplate.

Use the following procedure to attach 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.

Step 2 Attach the port adapter end of a Token Ring interface cable, or other connection equipment, to the interface port. (See Figure 13).

To MAU or MSAU

Caution Each 4R port adapter interface must be configured for the same ring speed as the ring to which it is connected; either 4 or 16 Mbps. If the 4R port adapter interface is set for a different speed, it will cause the ring to beacon, which effectively brings the ring down and makes it inoperable.

Step 3 Attach the network end of the Token Ring interface cable to the appropriate Token Ring equipment atyour site: a MAU or MSAU.

This completes the procedure for attaching interface cables to the 4R port adapter.
