Overview

Applications

A switch boosts network performance by segmenting a single large collision domain into smaller, separate collision domains. It also provides dedicated connections for heavily loaded networks using work stations and servers. In addition, the Full Duplex capability of Ethernet switches permits long distance connectivity for backbone applications or high throughput for high-performance dedicated servers. The NH2025-10 combines 10/100Mbps switched ports with a dport for accommodating an optional module.

The NH2025-10 switch can connect up to twenty-four 10/100Mbps ports and with a dport for accommodating an optional module Figure 2 illustrates various connection possibilities: Two NH2025-10 switches ,with Gigabit Ethernet uplink modules, located in different buildings can be connected via MM or SM fiber optic cable to a Gigabit Ethernet backbone. VLAN Tagging allows the creation of one logical VLAN across all switches. Additional connections include dedicated 10/100Mbps workgroup connections and 100Mbps dedicated servers.

Figure 2 - Typical Application Example

NOTE: The NH2025-10 does not count as a repeater. Each of the segments connected to the switch can support a full Ethernet network; there can be up to four 10Base-T repeaters/hubs between any NH2025-10 port and any station.

Network Management Systems

Network management functions greatly assist in monitoring and controlling the network. The NH2025-10 can be monitored and controlled through MegaVision or through a generic SNMP- based NMS. The connection to the NH2025-10 may be achieved through Ethernet.

To enable management of an NH2025-10 device, you must define the device and provide specific parameters to establish communication. The Describe window is used to define a new device or to change the parameters of a previously defined device.

The NH2025-10 can also be configured and managed through the Command Line Interface.
