Chapter 1 Introduction
The 4-Slot Modular Switch 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.
The 4-Slot Modular Switch 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/TX can be
accommodated in the host cabling. Any of the above
modules can be integrated to give up to many different
configurations.

Device Description, Features and Capabilities
4-Slot Modular Switch Front and Rear Panels
This section describes the features on the front and rear
panels of the 4-Slot Modular Switch unit.
Figure 1-2. Front Panel
Figure 1-3. Rear Panel
All LED status indicators are located on the FRONT
panel of the switches. They provide a real-time indication
of system and operational status. The ports for
connections to other devices and networks are also on
the front panels, along with the crossover switches. The
following sections provide descriptions of the LED
indicators and ports.
LED
Indicators Explanation
Power The red power indicator is illuminated when power is provided to the switch and
the switch is turned in the ON position.
Link/Activity
Green Link/Activity indicators are
illuminated when the switch detects a
connection to that port. The indicator
blinks when data is transmitted over the
network connected to that port.
When a port is not connected, the
indicator is off.

Full
Duplex/Col
Red Full Duplex/Col indicators are
illuminated when that port is in full duplex
mode. The indicator is off when that port is
in half duplex mode.
When a collision occurs on the network
connected to a port, that Full Duplex/Col
indicator blinks.
100Mbps
Green 100Mbps indicators are illuminated
when the port is operating in 100Mbps
mode. The indicator is off when the port is
operating in 10Mbps mode.
 Power Port
The power port accepts the power plug.
 Power Switch

2 km (62.5/125µm), 2 km (50/125µm) in length.
 In Single-mode, the fiber optic segment cannot

1000BASE-SX /LX / TX Network Guideline

Network Planning
Using a switch, such as a 4-Slot Modular Switch, can
expand network topologies and enhance network
performance.
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
1000Base-SX/LX/T networks 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 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 Network
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.

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 collapsed backbones.

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

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 2-5 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 1000Base-LX, 1000Base-SX or
1000Base-T port.

Chapter 3 Installation
The Switch can be installed quickly and easily.
However, for an installation with minimum impact on
the existing network, please read this chapter
carefully.
Installing a 4-Slot Modular Switch 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.
