CHAPTER 1 INTRODUCTION

DES-1200M are multi-speed network devices combining
Ethernet, Fast Ethernet and Gigabit Ethernet capabilities
in a single compact, rack-mountable cabinet. Combining
10Mbps Ethernet, 100Mbps Fast Ethernet and Gigabit
Ethernet interfaces in one unit allows these switches to
unclog existing LANs and provide a path to efficient,
high-speed networking.

DES-1200M is a combination of a 4-slot host cabinet
which accepts more than 15 different media modules. A
maximum configuration of 32 x 10/100Base-TX switched
ports can be achieved using 4 X 8 port 10/100Base-TX
modules. In the same way, a maximum configuration of
32×10/100Base-TX or 8/16/32 ×100Base-FX ports, or 4

x 1000Base-SX/LX can be accommodated in the host
cabling. Any of the above modules can be integrated to
give up to many different configurations.

CHAPTER 2 PLANNING YOUR NETWORK

Before you install your DES-1200M, you should review the
guidelines for setting up Ethernet networks. Further, you should
plan your network to take maximum advantage of its switching
capabilities.

10Base-T Ethernet Network Guidelines

 The maximum length of a 10Base-T cable segment is 100

meters (328 feet).

 The maximum number of nodes on a 10Base-T segment is

100 meters (328 feet).

 The maximum number of hubs on a 100Base-TX segment

is one if using Class I hubs and two if using Class II hubs.

 The recommended cable type is EIA/TIA Category 5

untwisted-pair.

13

 The maximum network diameter is 200 meters (656 feet)

when using Class I hubs and 205 meters (672.5 feet) when
using Class II hubs.

100Base-FX Fast Ethernet Network Guidelines

Network Planning

Using a switch, such as a 4-Slot Modular Switch, can expand
network topologies and enhance network performan c e.

Each port on a switch connects to a separate network with its
own collision domain. Separating networks with these switches
allows you to expand 10Base-T networks past the four-hub limit
and expand 100Base-TX networks past the one or two hub limit.

These switches also filter incoming traffic. On standard hubs
and repeaters, any data received on a port is forwarded to all of
the other ports. On switches, data received on one port is
forwarded only to the port of the destination device, and if the
traffic is local, the data is not forwarded at all. Also, switches
can forward multiple data transaction at once.

To expand your network topology or enhance network
performance, use the Max Switch II as collapsed backbone or
to increase file server performance, to segment large networks,
to interconnect 10Mbps networks with 100Mbps networks, or to
overcome the limitations of 10Base-T and 100Base-TX
networks.

Expanded Networks

You can expand your 10Base-T or 100Base-TX or 1000Base­SX/LX network beyond its hub limit by adding a 4-Slot Modular
Switch.

10Base-T Networks

10Base-T Networks are limited to four hubs between any two
nodes. By adding your 4-Slot Modular Switch to a network, you
can divide that network into segments with their own collision
domains. In other words, you can connect one 10Base-T

15

network with four hubs to your 4-Slot Modular Switch. Then you
can connect another 10Base-T network with four hubs to your
4-Slot Modular Switch. You will then have one network with two
collision domains, allowing four hubs on each port.

Figure 2-1. Expanding your 10Base -T Net w ork

100Base-TX Networks

The hub limit of a 100Base-TX network depends on the class of
the hub in the network. With a Class I hub, the network is
limited to one hub. With a Class II hub, the network is limited to
two hubs.

However, you can expand your 100Base-TX network that
includes either class of hub by adding a 4-Slot Modular Switch.
With the 4-Slot Modular Switch added to your 100Base-TX
network, you can separate that network into individual
segments with their own collision domains. In other words, you
can connect one 100Base-T network with one or two hubs to
the 4-Slot Modular Switch, and you can connect another
100Base-TX network with one or two hubs to the 4-Slot
Modular Switch. You will then have one network with two
collision domains.

16

Figure 2-2. Expanding your 100Base-TX network (Class I)

Collapsed Backbone Link

Traditionally, bridges and routers have been used to link local
area networks into one interconnected network. But these
devices involve difficult management and long traffic delays.

The 4-Slot Modular Switch providers multiport bridges with short
delays, easy setup and maintenance, making it ideal for
backbone links. Also, the Built-in filtering on this hub deceases
network traffic, while the multiple ports that communicate
simultaneously increases network performance.

One or more of your hub's 100Mbps or 1000Mbps ports can be
used as a high-speed backbone link to other hubs serving as

17

collapsed backbones.

Figure 2-3. 4-Slot Modular Switch 100/1000 Hub in a collapsed

backbone link

18

Fileserver Link

100Base Solution

With a fileserver link, you can increase file server performance
by increasing the Hub's bandwidth between one or more
fileservers and the workgroups they serve.

If you connect 10Mbps workgroup hubs to the 10Mbps ports on
the 4-Slot Modular Switch, traffic in one workgroup will not
interfere with the performance of another workgroup.

Figure 2-4. Fileserver Link

19

Connecting servers through 100Base-TX ports increases
performance to the clients, even if the clients are on 10Base-T
segments.

Because multiple 10Base-T devices can access the file server
at the same time through a 100Base-TX connection,
performance increases to beyond the performance of standard
10Base-T or 100Base-TX hubs. Operating the 4-Slot Modular
Switch at full duplex further increases performance

1000Base Solution

You can upgrade your server with a Gigabit Ethernet NIC, and
introduce a Gigabit backbone switch too. This contains several
switch ports which provides much faster access to your server
with minimum disruption. See Figure 16.

Multi-port Bridge with High-Bandwidth Backbone

With a 4-Slot Modular Switch, you can divide large network to
ease congestion, and connect 10Base-T networks to 100Base­TX or 100Base to 1000Base networks for more flexibility.
Adding your 4-Slot Modular Switch to a large network creates
more segments in that network. The 4-Slot Modular Switch
built-in filtering function separates a segment's local traffic from
network traffic, reducing the amount of network traffic and
easing congestion.

20

Figure 2-5. Used as a Multiport Bridge

Using your hub, you can also connect 10Base-T networks and
100Base-TX and 1000Base-SX/LX networks together for more
flexibility in your network topology. As in the Figure 16 shown
above, the 4-Slot Modular Switch can connect through one port
to a 10Base-T network, and through another port, connect to a
100Base-TX port, creating one network. This switch can also
connect to a 1000 Base-LX or SX port.

21

CHAPTER 3 INSTALLATION

The DES-1200M can be installed quickly and easily. However,
for an installation with minimum impact on the existing network,
please read this chapter carefully.

Installing a DES-1200M involves three steps:

1. Choosing a location

2. Supplying power

3. Connecting the switch

Choosing A Location

The location of the switch is based on the following criteria:

 Avoid dusty locations.
 Avoid electromagnetic noisy areas, such as locations close

to power transformers or radio transmitters.
 Avoid temperatures below 32 Degrees Fahrenheit and

over 122 Degrees Fahrenheit.

 Allow a clear view of the front panel LED indicators.
 Allow easy access to the front panel ports and the rear

panel switches.
After choosing an appropriate location, you can install the

switch on a desktop or in a rack.

22

Rack Installation

Your switch comes with two rack mounting brackets. you can
use these brackets to mount the switch on an EIA standard 19"
rack. Attach the brackets to the switch, using the screws
provided.

Figure 3-2. Attaching the mount brackets for rack installation

Next, install the switch in the rack using the screws provided to
attach the brackets to the rack.

23

Supplying Power

The DES-1200M is equipped with a universal switching power
supply that accepts AC input voltages from 100 to 240VAC and
50 to 60 Hz.

To supply power to your switch:

1. Plug the connector of the power cord into the power port on

the rear panel of your switch.

2. Plug the other end of the power cord into an AC wall outlet.

3. Set the power switch to ON and verify that the Power LED
