3. Making Network Connections

3.1 Network Switched Ports

16 switched ports and 24 switched ports are provided on these two
switch models respectively. Each port is equipped with one RJ-45 con­nector at least. Both models provide one additional uplink RJ-45 connec­tor on Port 16 and Port 24 respectively. Some switched ports are designed
with trunking function optionally.

Figure 3-1 Network Switched Ports

-8-

 Switched Ports

Each switched port supports one connection to a LAN segments. Each

segment is an independent shared network in one collision-domain.

The connection can be to either a 10BASE-T or 100BASE-TX device.

 MDI-X RJ-45 Connectors

MDI-X jack is labeled [X] normally to indicate the jack is designed

with internal crossover function. It allows a connection to an end

station using straight-through UTP cable.

 Uplink MDI RJ-45 connectors

One additional MDI RJ-45 connector of each switch is provided for

easy uplink via standard straight-through UTP to other device that

supports MDI-X RJ-45 connector.

 Trunking Ports

Some switched ports can be optionally used for supporting trunking

function. This option depends on the trunking configuration setting

on rear panel. Refer to section 3.7 for more information.

3.2 Pin Assignments of MDI-X and MDI RJ-45

The following table shows the pin assignments of MDI-X and MDI RJ-45
connector respectively:

PIN# MDI-X Jacks MDI Jack

1 Rx+ Tx+
2 Rx- Tx­3 Tx+ Rx+
6 Tx- Rx-

4,5,7,8 NC NC

-9-

3.3 UTP Cables

When making a connection to another device using straight-through
UTP cable, make sure MDI-X to MDI connection rule is followed. The
following figure illustrates the pin assignments of a straight-through
UTP and a crossover UTP cable:

Figure 3-2 Straight-through and Crossover UTP Cable

It is suggested to use straight-through UTP cables for all UTP connec­tions. The maximum length and UTP cable categories used for the con­nections to a 10BASE-T device and 100BASE-TX device are:

CONNECTED DEVICE UTP CABLE USED & MAXIMUM LENGTH

10BASE-T device Cat. 3, 4, 5 UTP (100 meters)

100BASE-TX device Cat. 5 UTP (100 meters)

-10-

3.4 UTP Connections

The switch can support connections to the following devices:

_ 10BASE-T or 10/100BASE-TX network cards
_ 10BASE-T hub ports
_ 100BASE-TX hub ports
_ 10/100BASE-TX dual speed hub ports
_ 10/100BASE-TX switch ports

The following figure illustrates some connection examples:

Figure 3-3 Example of Connections to Different Devices

-11-

3.5 Operating Mode

All switched ports are designed as auto-negotiation capable switched
ports. Each port can determine the speed and duplex type used automati­cally through an auto-negotiation process with the remote connected
auto-negotiation capable device. The auto-negotiation process is per­formed upon the connection is made.

When connecting to a non-auto-negotiation device, each port also fea­tures the capability to auto-sense the connection speed.

The following table lists the operation mode used for the switched port
when it connects to different devices. The operating mode includes the
connection speed and duplex type.

Device Connected Operation Mode Used

10BASE-T hub 10Mbps, half-duplex

100BASE-TX hub 100Mbps, half-duplex

Auto-negotiation device Auto-negotiation *2

Non-auto*1 half-duplex device auto-speed-sensing *3, half-duplex

Non-auto full-duplex device Not supported

*1 Non-auto : non-auto-negotiation

*2 determined through auto-negotiation process

*3 speed is determined by auto-sensing function

Most of 10BASE-T hubs and 100BASE-TX hubs are non-auto-negotia­tion devices and operate on half-duplex mode.

3.6 Port-based VLAN Support

Each port of the switch unit connects to one individual LAN segment.
There can be many Ethernet nodes located on each segment. The switch
performs network data forwarding between different LAN segments. It al­lows Ethernet nodes located on different segments to communicate with
each other. Basically, all Ethernet nodes are in one single LAN.

For the purposes of security need or to minimize broadcasting messages,
the switches support a port-based VLAN (Virtual LAN) function. It al­lows you to divide the switched ports into 2 groups via a VLAN configu­ration setting. Each port is associated with one LAN segment. As long as
the setting is made, the Ethernet nodes located in same group compose
one individual virtual LAN and the nodes located in different groups are
unable to communicate with each other.

The VLAN configuration slide switch is located on the rear panel of the
switch. Three setting positions are provided for selection.

Figure 3-4 VLAN Configuration Setting Switch

-13-

Two groups are defined when VLAN function is enabled. The setting 1
defines two groups without any overlapping. These two groups are in­dependent and isolated. No network data can be forwarded between two
groups. However, the setting 2 defines two groups with some overleap­ing ports. The overlapping ports belong to two groups at the same time.
They are able to communicate with any Ethernet nodes globally. De­pending on your application need, choose the appropriate setting for
your installation.

3.7 Trunking Support

Two switch units can be cascaded together through any regular switched
port on each unit when an expansion is required. However, the transfer
bandwidth between the two cascaded ports is limited to 200Mbps full
duplex.

To increase the bandwidth for the connection between two switch units,
a trunking function is implemented on the switch unit for this purpose.
Some ports can be configured optionally as trunking ports. A pair of
trunking ports composes one trunk. Two switch units can be cascaded
through one trunk (two ports and two cables). The aggregated band­width of one trunk can be up to 400Mbps.

The port pairs which are equipped with trunking function are:

Figure 3-5 Trunking Ports

-14-

The trunking configuration setting switch is located on the rear panel
and the settings are:

Figure 3-6 Trunking Configuration Setting Switch

The following figure illustrates an example of trunk connection between
two switches:

Figure 3-7 Example of One Trunk Connection

-15-

Note :

1. A pair of crossover UTP cables should be used at the same time for

one trunk connection. The length of each cable can be up to 100
meters.

2. When the switched ports are enabled as trunking ports, they can

only serve trunking function, but no other function.

3. The 16-port switch and 24-port switch can trunk to each other.

4. Since the trunking is proprietary, the switches do not support trunk

connection to other brand s switches.

The following figure illustrates another example of trunk connections
between three switches:

Figure 3-8 Example of Two-Trunk Connections

-16-

4. LED Indicators

4.1 LED Panels

The switch provides comprehensive LED indicators for diagnosing and
monitoring the operation of the unit as illustrated below:

Figure 4-1 LED Panels

-17-

4.2 Interpretation

Each switched port has three LED indicators to indicate its own port
status. The interpretations of each LED are:

POWER LED : indicates the status of the power supplied to the switch.

Link/ACT. LED : indicates the port cable link and traffic activity.

10M/100M LED : indicates the connection speed used

FDX/COL. LED : indicate the duplex mode used and collision status

The states and indications are:
