Featuring high reliability anfiguration flexibility, the System 5000 delivers a powerful solution for implementing and supporting LattisSphere(tm) structured networking environments comprised of SynOptics System 3000 and System 2000 hubs. THE SYSTEM 5000 SOLUTION SynOptics' Model00 is the first intelligent hub platform to deliver a structured networking solution for today's legacy networks with a migration path to future LAN technologies. Featuring a highly-flexible backplane architecture, the hub supports multiple 10 megabit per second (Mb/s) Ethernet, 4 and 16 Mb/s Token Ring and 100 Mb/s Fiber Distributed Data Interface (FDDI) networks simultaneously. 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 System 3000- and 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 migrate their shared-media LANs to switched backbone networks without sacrificing existing investments. MODEL 5000 PLATFORM The Model 5000 offers 14 slots to hold any combination of System 5000 Ethernet, Token Ring and FDDI host and network management modules. Fully configured, the hub provides a powerful platform for simultaneously supporting up to 12 Ethernet segments, nine Token Rings and five FDDI ring paths with extensive management capabilities. Network managers can perform precise, detailed management operations such as high-performance traffic monitoring and packet and protocol analysis at full line speeds. In addition, core management capabilities are provided for up to 52 Ethernet and 26 Token Ring networks operating within the hub, providing visibility into network operating conditions. Core management allows network managers to monitor hub hardware status, control hub configuration and obtain simple network performance statistics. The Model 5000 also provides an open path for integrating emerging technologies that will support future network growth. For instance, the hub is designed to accommodate high-speed packet switching and Asynchronous Transfer Mode (ATM) cell switching capabilities as they become available. Three versions of the Model 5000 hub are available, each offering different backplane configurations. The Model 5000N supports full IEEE 802.3-compatible Ethernet installations for high-density Ethernet environments. The Model 5000NT is identical to the Model 5000N, with the addition of IEEE 802.5 Token Ring capabilities for mixed Ethernet/Token Ring environments. The Model 5000F is identical to the Model 5000NT, with the addition of an FDDI backplane for complex Ethernet/Token Ring/FDDI environments. The FDDI backplane can also be installed as a simple upgrade in the network center, allowing users to add high-speed FDDI capabilities to existing Ethernet and Token Ring hubs. New technologies such as ATM will also be added incrementally by installing a new backplane section, enabling users to invest in a base unit today that can be easily upgraded to satisfy future requirements. EFFICIENT CONFIGURATION To maximize front-panel availability, the Model 5000's power supplies and cooling system are stored in a cage assembly in the rear of the hub. The Model 5000 employs a unique -48V DC power source on the hub backplane, offering a cost-effective system capable of delivering more than 100W per slot, and 1550W total, to support high-power redundant configurations and future power-hungry switched technologies. Tight-tolerance +5V and +12V are maintained by DC-to-DC converters on each module, providing the 950W of power required by current System 5000 modules. The power supply, which tolerates wide power swings to maintain stable performance during hot-swap operations, also offers an easy migration path to -48V battery-backed environments in the future. MODEL 5110 SUPERVISORY MODULE A Model 5110 Supervisory Module also resides in the rear of the Model 5000 chassis, delivering a rich set of common management and status functions throughout the hub. The Model 5110 regularly inventories components installed in the hub and monitors their status, storing configuration data in non-volatile memory. By redundantly storing the information, the Supervisory Module ensures the hub's configuration will never be lost, even following a power cycle. The module also maintains a front-panel DB-9 Service Port that provides access to all 14 hub slots, enabling users to collect specific configuration and status information from installed modules. INTERNAL MANAGEMENT BUS Each Model 5000 chassis includes a Common Management Bus (CMB), a 16-bit parallel backplane bus that supports internal communications between all installed modules, including the Supervisory Module, at speeds up to 32 Mb/s. The CMB also plays a key role in transmitting core management statistics between host and network management modules. The bus, which supports a variety of large-block transfers within the hub, also provides a necessary link between distributed software applications running on various modules installed in the Model 5000. RELIABILITY The Model 5000's high-quality design is intended to make it the industry's most reliable hub platform. In the unlikely event of a component failure, the hub includes a number of redundant back-up systems that eliminate any single point of failure. These back-up systems include: * REDUNDANT COOLING. A dual fan unit evenly distributes air flow to all installed components, even in only one of the two fans is operating. * REDUNDANT POWER SUPPLIES. Full load-sharing power supplies can be configured to support 950W and 1550W redundant configurations. The Supervisory Module actively monitors power usage and automatically reports via an LED display when a redundant configuration is no longer present. * REDUNDANT CLOCKS: Should the primary source fail, a back-up unit is activated by the Supervisory Module to monitor and distribute module clock rates to all slots. * REDUNDANT CONFIGURATION STORAGE: Back-up copies of the hub configuration data are stored on each individual module, protecting against a Supervisory Module failure. If the Model 5110 does fail, the module will shut down without affecting ongoing LAN performance. A new module can be hot-swapped to replace the failed unit and network operations will continue uninterrupted without compromising or losing the hub's configuration. LED INDICATORS The Model 5000 offers a series of LED indicators to report hub status at a glance. The LEDs, which appear both on the front and back of the hub, indicate power, cooling, Supervisory Module, redundant power configuration and overall system health status. In addition, LED displays on each module installed in the hub provide additional information regarding the various network LANs and overall system operations.
