Chapter 1 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-speed LAN technologies have been proposed to provide

greater bandwidth and improve client/server response times. Among them,

100BASE-T (Fast Ethernet) provides a non-disruptive, smooth evolution

from the current 10BASE-T technology. The non-disruptive and smooth

evolution nature, and the dominating potential market base, virtually guar-

antee cost effective and high performance Fast Ethernet solutions in the

years to come.

100Mbps Fast Ethernet 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-effective way 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 different

segments, which don’t compete with each other for network transmission

capacity.

The switch acts as a high-speed selective bridge between the individual

- 2 -

segments. The switch, without interfering with any other segments, auto-

matically 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-repeater limit." 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 the 205-meter

network diameter limit for 100BASE-TX networks. 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 laten-

cies. Routers have also been used to segment local area networks, but the

cost of a router, the setup and maintenance required make routers rela-

tively impractical. Today switches are an ideal solution to most kinds of

local area network congestion problems.

Features

The Switches were designed for easy installation and high performance in

an environment where traffic on the network and the number of user in-

crease continuously.

The Switches with their small, compact size were specifically designed for

small to middle workgroups. These Switches can be installed where space

is limited; moreover, they provide immediate access to a rapidly growing

network through a wide range of user-reliable functions.

The Switches are ideal for deployment with multiple high-speed servers for

shared bandwidth 10Mbps or 100Mbps workgroups. With the highest

bandwidth 200Mbps (100Mbps full-duplex mode), any port can provide

workstations with a congestion-free data pipe for simultaneous access to

the server.

The Switches are expandable by cascading two or more switches together.

- 3 -

As all ports support 200Mbps, the Switches can be cascaded from any

port and to any number of switches.

The Switches are a perfect choice for site planning to upgrade to Fast

Ethernet in the future. Ethernet workgroups can connect to the Switches

now, and change adapters and hubs anytime later without needing to

change the Switches or reconfigure the network.

The Switches combine dynamic memory allocation with store- and-forward

switching 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.

The Switches are unmanaged 10/100 Fast Ethernet Switch that offers

solutions in accelerating small Ethernet workgroup bandwidth.

Other key features:

 Auto MDI/MDIX for each port for Uplink to another switch, hub or

repeater.

 Store and forward switching scheme capability. As the result of

complete frame checking and error frame filtering, this scheme

prevents error packages from transmitting among segments.

 N-Way Auto-negotiation for any port. This allows for auto-sensing

of speed (10/100Mbps) thereby providing you with automatic and

flexible solutions in your network connections.

 Flow control for any port. This minimizes dropped packets by

sending out collision signals while the port’s receiving buffer is full.

Note that flow control is only available in half-duplex mode.

 Data forwarding rate per port is at wire-speed for 100Mbps speed.

 Data forwarding rate per port is at wire-speed for 10Mbps speed.

 Data filtering eliminates all error packets, runts, etc., per port at

wire-speed for 100Mbps speed.

 Data filtering eliminates all error packets, runts, etc., per port at

wire-speed for 10Mbps speed.

 Up to 1K active MAC address entry table with self-learning and

table-aging for the Switch.

Chapter 2 Unpacking and Setup

This chapter provides unpacking and setup information for the Switches.

Unpacking

Open the shipping cartons of the Switch and carefully unpacks its contents.

The carton should contain the following items:

 One 5/8-port 10/100Mbps Ethernet Switch

 One external power adapter

 This User’s manual

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

for replacement.

Setup

The setup of the Switch can be performed using the following steps:

 The surface must support at least 1.5 Kg for the Switch.

 The power outlet should be within 1.82 meters (6 feet) of the

Switch.

 Visually inspect the DC power jack and make sure that it is fully

secured to the power adapter.

 Make sure that there is proper heat dissipation from and ade-

quate ventilation around the Switch. Do not place heavy objects

on the Switch.

Note:To prevent from device damage, please use the bundled AC Adapter

before power on your Switch.
