ABOUT THIS GUIDE

Congratulations on your purchase of the 16-Port 10/100/1000Mbps + 2 Combo

Mini GBIC Gigabit Smart Switch. This device integrates 1000Mbps Gigabit

Ethernet, 100Mbps Fast Ethernet, and 10Mbps Ethernet network capabilities in

a highly flexible package.

Purpose

This manual discusses how to install and configure the DGS-1216T Web Smart

Switch.

Terms/Usage

In this manual, the term “Switch” (first letter upper case) refers to your DGS-

1216T Web Smart Switch, and “switch” (first letter lower case) refers to other

Ethernet switches.

INTRODUCTION

This chapter describes the features of the DGS-1216T and some background

information about Ethernet/Fast Ethernet/Gigabit Ethernet switching

technology.

Gigabit Ethernet Technology

Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same

packet structure, format, and support for CSMA/CD protocol, full-duplex, flow

control, and management objects, but with a tenfold increase in theoretical

throughput over 100-Mbps Fast Ethernet and a hundredfold increase over 10-

Mbps Ethernet. Since it is compatible with all 10-Mbps and 100-Mbps Ethernet

environments, Gigabit Ethernet provides a straightforward upgrade without

wasting a company’s existing investment in hardware, software, and trained

personnel.

The increased speed and extra bandwidth offered by Gigabit Ethernet are

essential to coping with the network bottlenecks that frequently develop as

computers and their busses get faster and more users use applications that

generate more traffic. Upgrading key components, such as your backbone and

servers to Gigabit Ethernet, can greatly improve network response times as well

as significantly speed up the traffic between your subnets.

Gigabit Ethernet enables fast optical fiber connections to support video

conferencing, complex imaging, and similar data-intensive applications.

Likewise, since data transfers occur 10 times faster than Fast Ethernet, servers

outfitted with Gigabit Ethernet NIC’s are able to perform 10 times the number

of operations in the same amount of time.

In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the

most cost-effective method to take advantage of today and tomorrow’s rapidly

improving switching and routing internetworking technologies. Also, with

expected advances in the coming years in silicon technology and digital signal

processing that will enable Gigabit Ethernet to eventually operate over

unshielded twisted-pair (UTP) cabling, outfitting your network with a powerful

1000-Mbps-capable backbone/server connection creates a flexible foundation

for the next generation of network technology products.

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 guarantees cost-effective and

high performance Fast Ethernet solutions.

100Mbps Fast Ethernet is a 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 bridges 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 do not compete with each other for network transmission

capacity.

The switch acts as a high-speed selective 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.

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.

VLAN (Virtual Local Area Network)

A VLAN is a group of end-stations that are not constrained by their physical

location and can communicate as if on a common broadcast domain, a LAN.

The primary utility of using VLAN is to reduce latency and need for routers,

using faster switching instead. Other VLAN utility includes:

Security: Security is increased with the reduction of opportunity

in eavesdropping on a broadcast network because data will be

switched to only those confidential users within the VLAN.

Cost Reduction: VLANs can be used to create multiple broadcast

domains, thus eliminating the need of expensive routers.

Port-based (or port-group) VLAN is the common method of implementing a

VLAN, and is the one supplied in the Switch.

UNPACKING AND INSTALLATION

This chapter provides unpacking and installation information for the Switch.

Unpacking

Open the shipping carton of the Switch and carefully unpacks its contents. The

carton should contain the following items:

One DGS-1216T Web Smart 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

CD-ROM with Web Management Utility and Manual

Quick Installation Guide

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

replacement.

Installation

The site where you install the hub stack may greatly affect its performance.

When installing, consider the following pointers:

Install the Switch in a fairly cool and dry place. See Technical

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 (4in) of space at the front and rear of the hub

for ventilation.

Install the Switch on a sturdy, level surface that can support its

weight, or in an EIA standard-size equipment rack. For

information on rack installation, see the next section titled 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.

Figure 1. Attach the adhesive rubber pads to the bottom.

Rack Mounting

The Switch can be mounted in an EIA standard-size, 19-inch rack, 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.

Figure 2. Combine the Switch with the provided screws.

Then, use screws provided with the equipment rack to mount the Switch in the

rack.

Figure 3. Mount the Switch in the rack.
