INTRODUCTION

This chapter describes the features of DSS-16+ 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-TX (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

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 Switch is compatible with all

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 bridges and transmits

Ethernet packets at the MAC address level of the Ethernet protocol, 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. Each segment has its own bandwidth and it does not compete with

others for network transmission capacity.

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

segments. The switch forwards traffic from origin segment to destination

segment, without interfering with any other segments. 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 uplinking Fast Ethernet 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. The switch supports both traditional

10Mbps Ethernet and 100Mbps Fast Ethernet, which is also ideal for bridging

between the existing 10Mbps networks and the new 100Mbps networks.

LAN Switching technology is a marked improvement over the previous

generation of network bridges, which were criticized by their higher latencies.

Routers have also been used to segment local area networks. But, the router

expensive, difficult to setup, and maintenance intensive, these make it

relatively impractical for the network. Switch, on the other hand, is less

expensive, easier to setup, and practically maintenance free, which make it an

ideal solution to today’s local area network congestion problems.

Features

This high performance DSS-16+ was designed for a network environment

where traffic and the number of users increase continuously.

DSS-16+, with their small, desktop size, was specifically design for small to

middle workgroups. It provides immediate access to a rapidly growing

network through a wide range of user-reliable functions.

DSS-16+ is ideal for shared bandwidth 10Mbps or 100Mbps workgroups

with multiple high-speed servers. With the highest bandwidth at 200Mbps

(Full-Duplex mode), each port can provide a workstation with congestion-

free data-pipe for simultaneous access to the server.

DSS-16+ is expandable by cascading two or more switches together. As all

ports support 200Mbps (Full-Duplex mode), the Switch can be cascaded

from any port and to any number of switches.

DSS-16+ is a perfect choice for 10Mbps network site that could be upgraded

to Fast Ethernet in the future. Ethernet workgroups can connect to the Switch

now, and change adapters and hubs anytime later without changing the

Switch or reconfiguring the network.

DSS-16+ combines dynamic memory allocation with store-and-forward

switching method to ensure that the buffer is effectively allocated for each

port. It also controls the data flow between transmit and receive nodes to

guarantee against all possible packet loss.

DSS-16+ is an unmanaged 10/100Mbps Fast Ethernet Switch that offers

solutions to increase Ethernet workgroup bandwidth. Other key features are

as followed:

 Uplink/MDI-II (media dependent interface) port for uplink to another

switch or hub.

 Store and forward switching scheme. As the result of complete frame

checking and error frame filtering, this scheme prevents error packages

from transmitting among segments.

 NWay Auto-negotiation for any port. This allows auto-sensing of speed

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

solutions for your network.

 IEEE 802.3x flow control for full-duplex mode operation.

 Back pressure flow control for half-duplex mode operation.

 Data Forwarding Rate (per port) at wire-speed for both 10Mbps and

100Mbps speed.

 Data Filtering Rate (per port) at wire-speed for both 10Mbps and

100Mbps speed; eliminates all error packets, runts, etc.

 16K active MAC address entry table with self-learning and table ageing.

 512KBytes RAM buffer per device.

 Broadcast storm protection.

UNPACKING AND INSTALLATION

This chapter provides unpacking and setup information for DSS-16+.

Unpacking

Open the shipping cartons and carefully unpacks its contents. The carton

should contain the following items:

 One 16-port 10/100M NWay Fast Ethernet Switch

 One external power adapter

 Four rubber feet to be used for shock cushioning

 User’s Guide

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

for replacement.

Installation

The site where you install DSS-16+ may greatly affect its performance.

When installing, consider the following pointers:

 Install DSS-16+ in a fairly cool and dry place. See Technical

Specification for the acceptable operating temperature and humidity

ranges.

 Install DSS-16+ in a site free from strong electromagnetic source,

vibration, dust, and direct sunlight.

 Leave at least 10cm of space at the left and right hand side of DSS-16+

for ventilation.

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

to the power adapter.

IDENTIFYING EXTERNAL COMPONENTS

This section identifies all the major external components of DSS-16+. Both

the front and rear panel is shown, followed by a description of each panel’s

feature. The LED indicator panel is described in detail in the next chapter.

Front Panel

The figure below shows the front panels of DSS-16+.

16-port 10/100Mbps NWay Fast Ethernet Switch

LED Indicator Panel

Refer to the next chapter for detailed information about each LED indicator.

Rear Panel

Twisted-Pair Ports

Use any of these ports to connect network devices (workstations, hubs,

switches, etc.) to DSS-16+. These ports are MDI-X ports and you can use

ordinary straight-through twisted-pair cables to connect PCs, workstations,

and Servers to DSS-16+. If you need to connect these ports to devices with

MDI-X ports, you need to use crossover cables, or connect using the Uplink

port (described below).
