Occupying a single slot in the Model 5000 chassis and featuring IEEE 802.5 Token Ring compatibility, the Token Ring modules deliver advanced solutions for building structured Token Ring network environments. THE SYSTEM 5000 SOLUTION SynOptics' LattisSphere(tm) System 5000 represents the industry's first product family aimed at delivering a structured networking solution for today's legacy networks while providing an opeath to future LAN technologies. The Model 5000 is designed to support highly-segmented enterprise networks by providing a central point of integration and administration for distributed environments. Residing in the network center, the Model 5000 unites distributed Lattis System 3000- and Lattis System 2000- based Ethernet, Token Ring and FDDI networks as a single, cohesive system, optimizing the use of centralized network resources such as servers, bridges and routers. The Model 5000 also includes a built-in path to the high-speed switching technologies of the future, enabling customers to incrementally evolve their shared-media LANs to switched backbone networks without sacrificing existing investments. TOKEN RING MODULE OPERATION The System 5000 Token Ring host modules deliver complete connectivity solutions across a wide range of unshielded twisted pair and shielded twisted pair media. Occupying a single slot in the hub, the modules can operate at either 4 megabits per second (Mb/s) or 16 Mb/s over one of nine Token Ring data paths on the Model 5000 backplane, delivering unprecedented configuration flexibility for dynamic applications. All System 5000 Token Ring host modules include built-in automatic frequency-detection hardware, which prevents a Token Ring device from entering the network at the wrong speed. If a data-rate mismatch is attempted - such as a 4 Mb/s device connecting to a 16 Mb/s ring - the frequency detection circuitry automatically wraps the port, avoiding potential beaconing or alarm conditions on the network. Three System 5000 Token Ring host modules are available: the Model 5575-F Token Ring Intelligent Dual Cluster Repeater Host Module, the Model 5505P Token Ring Active Retiming Host Module and the Model 5502 Token Ring Passive Host Module. MODEL 5575-F TOKEN RING INTELLIGENT DUAL CLUSTER REPEATER HOST MODULE The Model 5575-F Token Ring Intelligent Dual Cluster Repeater Host Module provides distributed SynOptics workgroups with full access to centralized resources located in the network center. The Model 5575-F features two sets of duplex ST fiber connectors to support Ring-In/Ring- Out trunk connections to System 3000(tm) and LattisRing(tm) System 2000(tm) Token Ring workgroups distributed throughoutrprise. The ports provide connectivity for users located up to 2 kilometers away over 62.5/125 m and 50/125 m fiber optic cable. Full repeating functions are implemented on receive and transmit pairs for both primary and secondary ring paths. Each Ring-In/Ring-Out trunk connection is associated with a "cluster" consisting of three RJ-45 copper lobe ports, providing efficient access to centrally-located file servers, bridges and routers over readily-available shielded and unshielded twisted pair cabling. Each cluster can be assigned to any of nine Model 5000 backplane ring paths through software control, providing considerable flexibility for configuring the network. The clusters can alternatively attach to the local module-level ring, which is not connected to the backplane, or they can be removed entirely from both the module-level and backplane rings to establish independent, isolated clusters in the network center. Module-level and isolated rings provide core management capabilities which allow network managers to monitor hub hardware status, control hub configuration and obtain simple network performance statistics. A third port, called the Monitor Port, offers a single front-panel RJ-45 modular receptacle for attaching network diagnostic equipment in the network center. The equipment can be used to evaluate individual ring performance, using either front-panel push-button controls or via the network management system to select the desired ring number and speed. Each Ring-In/Ring-Out trunk port on the Model 5575-F also includes a built-in Frame Processing Unit (FPU) to provide the network management system with sophisticated ring diagnostic information. The FPU provides data such as frame counts, soft error counts, and Upstream Neighbor Address (UNA) notification to aid in network management and the port association process. MODEL 5505P TOKEN RING ACTIVE RETIMING HOST MODULE The Model 5505P Token Ring Active Retiming Host Module offers 20 RJ-45 modular receptacles to support 4 Mb/s and 16 Mb/s Token Ring host stations over both shielded and unshielded twisted pair cabling on the same ring. Each port can be individually assigned to any of the Model 5000 backplane rings or to the module-level local ring, giving network managers complete flexibility in configuring the network to meet their specific requirements. The module also incorporates data signal active retiming and regeneration on each lobe port, thereby reducing system jitter and signal loss to maintain highly-reliable performance over all twisted pair cabling types. The Model 5505P can be used to create single rings supporting up to 132 devices over a variety of structured cabling. The module supports lobe lengths up to 200 meters at 4 Mb/s and 100 meters at 16 Mb/s over Category 3 voice-grade unshielded twisted pair cabling, also known as D-Inside Wire (DIW). Lobe lengths of 300 meters (at 4 Mb/s) and 160 or 180 meters (at 16 Mb/s) are supported over high-grade, low-crosstalk Category 4 and Category 5 unshielded twisted pair cabling, respectively. For shielded twisted pair cabling environments, the Model 5505P supports lobe lengths of 600 meters (at 4 Mb/s) and 300 meters (at 16 Mb/s) over Type 1, Type 1A and Type 2 shielded twisted pair cabling; 400 and 200 meters (at 4 and 16 Mb/s) over Type 6 and Type 9 shielded twisted pair cabling; and 300 meters (at 4 Mb/s) and 150 meters (at 16 Mb/s) over Type 8 shielded twisted pair cabling. MODEL 5502 TOKEN RING PASSIVE HOST MODULE The Model 5502 Token Ring Passive Host Module offers 24 RJ-45 modular receptacles to support Token Ring host stations operating at 4 or 16 Mb/s over shielded twisted pair cabling and high-grade, low-crosstalk Category 4 and Category 5 unshielded twisted pair cabling. The Model 5502 provides a compact solution for high-density network environments. All 24 ports are connected to the same ring, which can operate over one of the nine Token Ring paths on the Model 5000 backplane or on the local module-level ring. The Model 5502 can be used to build individual Token Ring networks supporting a maximum of 250 devices over shielded twisted pair cabling or 132 devices on unshielded twisted pair. The module supports lobe lengths up to 200 meters at 4 Mb/s and 100 meters at 16 Mb/s over Category 4 and Category 5 unshielded twisted pair cabling, and 100 meters at 4 Mb/s over Category 3 DIW. Lobe lengths of 350 meters (at 4 Mb/s) and 180 meters (at 16 Mb/s) are supported over Type 1, Type 1A and Type 2 shielded twisted pair cabling. The module also supports lobes of 200 and 120 meters (at 4 and 16 Mb/s) over Type 6 and Type 9 cabling; and 150 meters (at 4 Mb/s) and 90 meters (at 16 Mb/s) over Type 8 cabling. ADAPTER CARD COMPATIBILITY The Model 5575-F, Model 5505P and Model 5502 have all been successfully tested for compatibility with IBM 16/4 Token Ring adapter cards, allowing for seamless integration of existing IBM/SNA networks into System 5000 environments. TOKEN RING MODULE MANAGEMENT System 5000 Token Ring modules are fully integrated into the SynOptics Optivity(tm) network management system, enabling network managers to monitor and control network activity from a central management station. Management data is forwarded to the network management system overhigh-speed, out-of-band Common Management Bus (CMB) on the Model 5000 backplane, ensuring rapid and timely reporting of network performance. The Token Ring modules appear in the Expanded View(tm) graphical user interface, providing unprecedented visibiy into the network topology. A variety of other views are also available, including the new Network Center View, which introduces a new method for managing and configuring the enterprise network from a central management station. LED INDICATORS Each System 5000 Token Ring module includes a comprehensive front-panel LED display matrix to indicate module performance and configuration at a glance. The Model 5575-F includes a module-level LED to indicate overall module status, as well as separate LED fields for the various cluster ports. The LEDs report which backplane rings the clusters are assigned to, the various ring speeds and whether the clusters are local or isolated from the backplane. Other conditions, such as beaconing, wrapping or the presence of a phantom signal, are also reflected on a per-cluster basis on the LED matrix display. The Model 5505P and Model 5502 include an overall module-status LED, as well as a series of indicators to report individual ring and port status. One field indicates which ring or rings on the backplane are being utilized by the module or by individual ports, and the status of those rings. A second field offers a series of port-level indicators to report the presence of a valid phantom signal or whether the port is wrapped.
