Page 5: Introduction
The NH 210 is managed through a Windows 95™-based graphical application program called MegaView. The management interface is provided via the PC parallel port (LPT1or LPT2) which is connected to the NH 210’s DB-25 front panel port, using a standard parallel printer cable. The switch offers a wide array of management capabilities, including powerful VLAN features on the NH 210-2K model, intrusion control security and real time port statistics. -
Page 6: Features
Ethernet segment switches divide a large unwieldy local network into smaller segments, insulating each from the other’s local traffic and increasing aggre- gate bandwidth, while still retaining full connectivity. The NH 210 is designed to be self-configuring and extremely fast, making installation simple and pro- viding an increase in available bandwidth. -
Page 7: Applications
Full Duplex capability of Ethernet switches permits long distance connec- tivity for backbone applications, or high throughput for high-performance ded- icated servers. The NH 210 combines 10Mbps switched ports with 100Mbps ports for Fast Ethernet backbone connection and dedicated 100Mbps servers. -
Page 8: Typical Configurations
NH 210 NBase Communications Typical Configurations Figure 2 illustrates the optimal connection possibilities of the NH 210. One switch can connect up to eight 10Mbps ports and two 10/100Mbps ports. Attachments can include 10Mbps and 100Mbps servers, a Fast Ethernet back- bone, 10/100Mbps hubs or individual stations, all functioning in Half/Full duplex mode. -

Page 13: Network Connections
Connecting the Ethernet Devices The 10Base-T and 100Base-TX ports on the NH 210 are designed to be con- nected directly to a server or PC, using a standard straight through patch cable. In order to cascade switches or connect a hub to the switch, a crossover cable... -
