The FDDI Workgroup Concentrators support up to 14 host stations operating at 100 megabits per second (Mb/s), delivering a compact, powerful solution for linking today's high-performance servers and workstations. The concentrators are also fully integrated with the Optivity(tm) network management system, SynOptics' premier management solution for a variety of network environments. Working from a number of leading UNIX-based management platforms, including Sun Microsystems' SunNet Maer, Hewlett-Packard's OpenView and IBM's RS/6000, Optivity represents the industry's most advanced distributed management solution for large, multivendor FDDI, Ethernet and Token Ring networks. LattisNet FDDI Workgroup Concentrators include two FDDI Media Access Control (MAC) elements - Primary and Local. The Primary MAC provides access to and allows management of devices connected to the Primary path. The Local MAC automates two processes that contribute to improved network reliability: intelligent insertion and removal of new stations, and the gathering of physical topology information. The concentrators are fully compatible with the International Standards Organization's FDDI MAC, Physical Medium Dependent (PMD) and Physical Protocol (PHY) standards, as well as the American National Standards Institute's (ANSI) X3T9.5 Station Management (SMT) specification. Three concentrator models are available, each supporting different media. Model 2912A SDDI Workgroup Concentrator The Model 2912A SDDI Workgroup Concentrator offers two fiber optic A and B ports and 12 Master ports with 9-pin D connectors to support host stations operating at 100 Mb/s over shielded twisted pair cabling. The Model 2912A supports connectivity up to 100 meters over IBM Type 1 or Type 2 shielded twisted pair cabling, as well as Type 6 shielded twisted pair patch leads, maintaining compatibility with existing cabling plants. SDDI, which defines the transmission of FDDI signaling over shielded twisted pair cabling, is based on interoperability specifications developed by an 11-member team of FDDI vendors. Model 2914 FDDI Workgroup Concentrator The Model 2914 FDDI Workgroup Concentrator features two fiber optic A and B ports and 12 Master ports implemented via Media Interface Connectors (MIC) for supporting 100 Mb/s FDDI host connections over fiber optic cabling. The Model 2914 supports host connections up to two kilometers (km) over 50/125 and 62.5/125 m multi-mode fiber cabling. Model 2915 FDDI Workgroup Concentrator The Model 2915 FDDI Workgroup Concentrator offers two fiber optic A and B ports and 12 RJ-45 modular receptacle Master ports to support host stations operating at 100 Mb/s over Category 5 unshielded twisted pair cabling. The Model 2915, which supports connections up to 100 meters between the concentrator and the host station, is compatible with the latest ANSI FDDI specification for twisted pair physical medium dependent (TP-PMD) operations. Configuration Flexibility The System 2000 family of FDDI concentrators support a wide variety of network configurations. The fiber-optic A and B ports enable the concentrators to be dual-attached to an FDDI trunk ring or dual-homed to higher-level FDDI concentrators. Alternatively, the B port can provide a single-attach connection to a higher-level FDDI concentrator while the A port supports an additional end-station. In a stand-alone (null-attach) configuration, the A and B ports can be used to support two additional host stations. Configuration and port status information may be obtained through front-panel LED indicators, from the network management station, or through the service port. Integrated Network Management System 2000 FDDI Workgroup Concentrators are configured to support SynOptics' Optivity network management system, enabling network managers to control the FDDI network with port- level precision. Optivity includes familiar SynOptics management features such as system- generated network maps, the Expanded View(tm) graphical user interface and full Simple Network Management Protocol (SNMP) compatibility. In FDDI networks, every station supports the American National Standards Institute's (ANSI) FDDI Station Management (SMT) protocol. LattisNet FDDI Woroup Concentrators collect SMT-generated data from attached stations, and an on-board AMD 29005 RISC processor processes the management frames within the concentrator. An SMT-to-SNMP proxy agent on the concentrator enables a central management station - a UNIX workstation running the Optivity application - to display the information as part of a network map discovered and displayed by SynOptics' Autotopology Plus(tm) mapping feature. From the central management station, network managers can obtain ecific fault, performance and configuration data from System 2000 FDDI Workgroup Concentrators located anywhere in the extended network. Through Expanded View, the network manager can summon a real-time view of the concentrator to monitor and control individual host connections. Standards-based Management SNMP support enables the FDDI Workgroup Concentrators to pass management data through bridges and routers in extended networks. SNMP compatibility also enables network administrators to manage LattisNet FDDI, Ethernet and Token Ring networks, as well as other SNMP-compatible devices, from a common management system. The concentrators include 2 megabytes (MB) of ROM on-board for incorporating full FDDI management information base (MIB), SMT, SNMP and diagnostic software for extensive management capabilities down to the port level. An additional 2 MB of RAM enables SMT and SNMP to be downloaded to the concentrators from the management station using TFTP. A local load option is also included to allow startup without intervention by the network management station. LattisNet FDDI Workgroup Concentrator Features LattisNet FDDI Workgroup Concentrators include a number of other features, including: * A serial service port, implemented via a male DB-9 connector, for local diagnostics and configuration. * A standard RS-232 DB-25 port enables the concentrators to be managed out-of-band over a modem link from a central management station should in-band communications fail. * An optical bypass switch control, implemented through a 6-pin mini- DIN connector, enables the network manager to remove the concentrator from the ring without causing the network to wrap. * Per-port LEDs indicate active ports, Link Error Monitor (LEM) alarm conditions, fault status, port partition status and whether the port is attached to the local or primary path. * Full compatibility with the LattisNet System 3000(tm) product family enables the FDDI workgroup concentrators to serve as sd-alone units or as satellite hubs supporting workgroups operating within larger networks.
