1. PRODUCT OVERVIEW

Description

This installation and user guide describes Cabletron’s ELH100-12/24TX Fast Ethernet hubs. These hubs provide the easiest method of upgrading your network to Fast Ethernet. There’s no need to replace your existing network infrastructure. Just add Cabletron’s hub to your network and attach any 10 or 100 Mbps device to any port on the hub. These hubs provide both a 10 Mbps segment needed for common file transfers, as well as a 100 Mbps segment for relieving serious network congestion, running multimedia applications, or satisfying power users.

These hubs include a wide range of configuration options. They can be stacked together (up to 6 high) to form a dual-speed network of up to 144 ports. With a Class II rating, they can also be easily cascaded to additional 10 or 100 Mbps hubs. With an optional switch/media module, you can link the hub’s 10 Mbps and 100 Mbps segments together to form a bridged network, allowing traffic to pass between the segments when required.

Optional switch/media modules are also provided for 10Base-T/100Base- TX and 100Base-FX media types. The fiber modules allow you to connect the stack to remote locations up to 1.24 miles away (2 kilometers). Each of these switch/media modules provide a switched connection to the stack, breaking the two-hop count for Fast Ethernet by placing all the devices attached to the module in a separate collision domain. The modules operate at full wire speed with full address and frame filtering. They automatically learn node addresses from the network and store them in a Media Access Control (MAC) address forwarding table. Incoming packets are then forwarded on to the stack or filtered based on the addresses in the packet.

The optional RMON/SNMP/Web Agent Module provides a broad range of management options. It includes a standards-compliant Simple Network Management Protocol (SNMP) agent. The SNMP agent allows network management station applications to collect and present status and performance information about the stack, as well as providing the ability to configure and control functions on the stack. The module also supports Remote Monitoring (RMON) for Statistics, History, Alarm and Event groups (Groups 1-3, 9).

Network management can be performed in-band using TCP/IP, Telnet, or via a SLIP connection to the serial console port on the Agent Module. This module also includes a built-in Web agent that provides management access via common http browsers such as Netscape Navigator and Microsoft’s Internet Explorer. In addition, the console port allows out-of- band management using a PC, terminal, or modem connection.

ELH100 specifications

The Cabletron Systems ELH100 is a robust and innovative networking device that was designed for use in high-performance network environments. Introduced during the late 1990s, the ELH100 served as a valuable solution for enterprises looking to enhance their network efficiency and reliability. This device is particularly notable for its combination of advanced features, cutting-edge technologies, and versatile characteristics.

One of the main features of the ELH100 is its ability to support multiple Ethernet standards, including 10BASE-T and 100BASE-TX, making it highly flexible for diverse networking needs. This multi-standard support provided businesses with the ability to upgrade their networking infrastructure without entirely replacing existing equipment, allowing for a more cost-effective transition to higher-speed connections.

The ELH100 is equipped with a variety of ports, enabling it to connect to various devices seamlessly. Its design includes multiple media access control (MAC) addresses and the capability of supporting a sizable number of simultaneous connections. This design ensures optimal performance, even in environments requiring high data throughput.

In terms of technology, the ELH100 utilizes a pioneering architecture for load balancing and traffic management. This technology ensures that network bandwidth is used efficiently, minimizing bottlenecks and latency while maximizing throughput. Additionally, the device features hardware-based switching, which accelerates data transmission within the network, providing a competitive edge in applications that demand high-speed access.

Another defining characteristic of the ELH100 is its management capabilities. The device supports remote management via simple network management protocol (SNMP), allowing network administrators to monitor performance, configure settings, and troubleshoot issues from a central location. Such features not only enhance usability but also contribute to improved network uptime.

The ELH100 also emphasizes security features, including VLAN support, which permits the segmentation of network traffic. This capability helps in isolating different segments of the network, increasing both performance and security by preventing unauthorized access to sensitive data.

In summary, the Cabletron Systems ELH100 is a noteworthy networking solution that amalgamates versatility, efficiency, and advanced technology, making it a mainstay in the networking devices market during the era of its popularity. Its multi-standard support, hardware-based switching, management features, and security protocols underscore its capability to meet the evolving demands of enterprise networking environments.
