Magnum 3000 Stackable Hubs provide a full line of features and options to economically support Ethernet networks. For demanding applications where the best quality and the highest reliability is needed, thousands of Magnum 3000s have been installed. These products have proven themselves to be the “best of breed” in 10Mb Ethernet Hubs. Two building-block hub models are available, with 24 and 12 shielded twisted-pair ports. LEDs at each port indicate network status. A rear bonus port provides for optional backbone media connectivity, typically using a fiber port module. Magnum 3000 stacks may include Magnum 3000X Mixed-Media Concentrators to configure a network solution for any environment. The design of the Magnum 3000 Stackable line incorporates an Inter-Repeater Bus (IRB) so that users can interconnect multiple units of the same or different types in a stack that operates as one logical unit, with or without SNMP management. An SNMP agent is available for Magnum 3000 stacks. One SNMP agent, installed anywhere in the stack, collects data and executes local port controls for the entire stack and all associated Ethernet segments. The Magnum 3000 stack can be managed by any of the network management products that support industrystandard SNMP agents, or by a Windows PC-based Network Management System software platform with graphical icons. The Magnum 3000 Hubs and all Magnum products are designed and manufactured in the USA and are backed by a threeyear warranty.
