INTRODUCTION

This chapter describes the features of the Switch and some background information about Ethernet/Fast Ethernet switching technology.

Fast Ethernet Technology

The growing importance of LANs and the increasing complexity of desktop computing applications are fueling the need for high performance networks. A number of high-speedLAN technologies have been proposed to provide greater bandwidth and improve client/server response times. Among them,100BASE-T(Fast Ethernet) provides anon-disruptive,smooth evolution from the current10BASE-Ttechnology. Thenon-disruptiveand smooth evolution nature, and the dominating potential market base, virtually guarantee cost effective and high performance Fast Ethernet solutions in the years to come.

100Mbps Fast Ethernet is a new standard specified by the IEEE 802.3 LAN committee. It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while maintaining the CSMA/CD Ethernet protocol. Since the 100Mbps Fast Ethernet is compatible with all other 10Mbps Ethernet environments, it provides a straightforward upgrade and takes advantage of the existing investment in hardware, software, and personnel training.

Switching Technology

Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridge Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or Fast Ethernet LAN segments.

Switching is a cost-effectiveway of increasing the total network capacity available to users on a local area network. A switch increases capacity and decreases network loading by dividing a local area network into differentsegments, which don’t compete with each other for network transmission capacity.

The switch acts as a high-speedselective bridge between the individual segments. The switch, without interfering with any other segments, automatically forwards traffic that needs to go from one segment to another. By doing this the total network capacity is multiplied, while still maintaining the same network cabling and adapter cards.

For Fast Ethernet networks, a switch is an effective way of eliminating problems of chaining hubs beyond the “two-repeaterlimit.” A switch can be used to split parts of the network into different collision domains, making it possible to expand your Fast Ethernet network beyond the205-meternetwork diameter limit for100BASE-TXnetworks. Switches supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for bridging between the existing 10Mbps networks and the new 100Mbps networks.

Switching LAN technology is a marked improvement over the previous generation of network bridges, which were characterized by higher latencies. Routers have also been used to segment local area networks, but the cost of a router, the setup and maintenance required make routers relatively impractical. Today switches are an ideal

solution to most kinds of local area network congestion problems.

Features

The Switch were designed for easy installation and high performance in an environment where traffic on the network and the number of user increase continuously.

The Switch with its rack size is specifically designed for middle to large workgroups. The Switch provides immediate access to a rapidly growing network through a wide range of user-reliablefunctions.

The Switch is ideal for deployment with multiple high-speedservers for shared bandwidth 10Mbps or 100Mbps workgroups. With the highest bandwidth 200Mbps (100Mbpsfull-duplexmode), any port can provide workstations with acongestion-freedata pipe for simultaneous access to the server.

The Switch is expandable by cascading two or more switches together. As all ports support 200Mbps, the Switch can be cascaded from any port and to any number of switches.

The Switch is a perfect choice for site planning to upgrade to Fast Ethernet in the future. Ethernet workgroups can connect to the Switch now, and change adapters and hubs anytime later without needing to change the Switch or reconfigure the network.

The Switch combine dynamic memory allocation with store-and-forwardswitching to ensure that the buffer is effectively allocated for each port, while controlling the data flow between the transmit and receive nodes to guarantee against all possible packet loss.

UNPACKING ANDINSTALLATION

This chapter provides unpacking and setup information for the Switch.

Unpacking

Open the shipping cartons of the Switch and carefully unpacks its contents. The carton should contain the following items:

One the 16(24)-port10/100Mbps Fast Ethernet Switch

One AC power cord, suitable for your area’s electrical power connections

Four rubber feet to be used for shock cushioning Screws and two mounting brackets

This User’s Guide (on CDRom or Floppy)

If any item is found missing or damaged, please contact your local reseller for replacement.

Installation

The site where you install the Switch stack may greatly affect its performance. When installing, consider the following pointers:

Install the Switch in a fairly cool and dry place. See Specifications for the acceptable temperature and humidity operating ranges.

Install the Switch in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight.

Leave at least 10cm of space at the front and rear of the hub for ventilation.

6

Install the Switch on a sturdy, level surface that can support its weight, or in an EIA standard-sizeequipment rack. For information on rack installation, see the next section,Rack Mounting.

When installing the Switch on a level surface, attach the rubber feet to the bottom of each device. The rubber feet cushion the hub and protect the hub case from scratching.

Rack Mounting

The switch can be mounted in an EIA standard-size,19-inchrack, which can be placed in a wiring closet with other equipment. Attach the mounting brackets at the switch’s front panel (one on each side), and secure them with the provided screws.
