Delivers advanced functionality to meet today's networking challenges while providing a platform for tomorrow's networking needs.
Incorporates extensive fault tolerance with load-sharing power supplies, fault tolerant controller modules, redundant links, fault tolerant management, redundant fans, and backup hubs for maximum uptime.
Offers multiple back-plane options, ranging from traditional Ethernet, Token Ring, and FDDI LAN services to LAN packet switching and ATM cell relay settings at gigabit/second rates.
Provides complete investment protection for ONline networks - accepting existing ONline modules as well as new ONcore modules.
Provides intelligent inventory and Power Management for ease of physical maintenance and network.
The ONcore Switching Hub provides investment protection by accepting all existing media modules in Chipcom's ONline Concentrator family, plus supporting future technologies. The ONcore Switching Hub can include up to three backplanes: enhanced TriChannel, RingChannel, and SwitchChannel. TriChannel supports ONcore Ethernet module and all ONline modules. RingChannel supports Ring topology networks: Token Ring and FDDI. The SwitchChannel backplane provides over 16 Gbps of ATM cell-switching capacity and 2 (3bps of packet-switching capacity. You can upgrade your network at your pace, as your network expands. You can upgrade your ONcore Hub to support whatever technology is required in your network. In addition, the ONcore backplanes offer the best in intelligent port and module switching for both Ethernet and Token Ring. With the flexibility to configure your network dynamically. the ONcore Switching Hub gives you "bandwidth on-demand."
Chipcom delivers the most complete fault tolerance in the industry with its ONcore Switching Hub. "N+1" load-sharing power supplies provide more than one kilowatt of power to the ONcore modules. Nil load sharing provides cost-effective power redundancy since only one more power supply than the system requires is needed for full backup. In addition, the ONcore System delivers an Intelligent Power Management Architecture. Whenever a new ONcore module is added to the ONcore Hub, the "signature" of the new module (power requirement stored in nonvolatile, on-board memory) is checked before powering up. If the new module requires more power than is available, the new module is not allowed to power on and the system alerts you of insufficient power. In the event of multiple power supply or fan failures, ONcore Power Management can excellent a partial shutdown of modules based oil module-priority specifications you set, ensuring that mission-critical network services stay up and running.
The ONcore System also supports Automated Inventory Management of all system elements for asset management and servicing purposes. Via Chipcom's ONdemand Network Control System, any SNMP-based network management platform, or through an ASCII terminal, you can query each ONcore Hub device for its "signature" and obtain all model and serial numbers, hardware and software revision levels, and power requirements for every system element.
Chipcom's ONcore FaultTolerant Controller Module provides system clock signals and essential system services for Chipcom's ONcore Switching Hubs and all ONcore and ONline modules. More important, it is the intelligence behind Chipcom's Intelligent Power Management Architecture and Intelligent Inventory Management features. The Fault-Tolerant Controller Module provides the processing power for all the environmental monitoring features of the hub: hub temperature, fan status, and power supply status. The FaultTolerant Controller Module resides in the ONcore Hub's dedicated controller slots, saving space in the hub payload for ONcore and ONline management and media modules. Two Fault-Tolerant Controller Modules are supported in the same hub, providing for "automatic switchover" redundancy of the controller function.
