3. Making LAN Connections

3.1 10/100/1000 TP Copper Port

The 10/100/1000 TP copper port supports the following connection types and distances:

Network Cables

10BASE-T: 2-pair UTP Cat. 3, 4, 5 , EIA/TIA-568B 100-ohm
100BASE-TX: 2-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
1000BASE-T: 4-pair UTP Cat. 5 or higher (Cat.5e is recommended), EIA/TIA-568B 100-ohm
Link distance: Up to 100 meters for all above

Auto MDI/MDI-X Function

This function allows the port to auto-detect the twisted-pair signals and adapts itself to form a valid MDI to
MDI-X connection with the remote connected device automatically. No matter a straight through cable or
crossover cable are connected, the ports can sense the receiving pair automatically and configure themselves to
match the rule for MDI to MDI-X connection. It simplifies the cable installation.

Auto-negotiation Function

The port is featured with auto-negotiation function and full capability to support connection to any Ethernet

-21-

devices. The port performs a negotiation process for the speed and duplex configuration with the connected
device automatically when each time a link is being established. If the connected device is also
auto-negotiation capable, both link partners will come out the best configuration after negotiation process. If
the connected device is incapable in auto-negotiation, the port will sense the speed and use half duplex for the
connection.

3.2 Making Fiber Connection

The SFP slots (FX port) must be installed with an SFP fiber transceiver for making fiber connection. Your
device may come with an SFP transceiver pre-installed when it was shipped.

Installing SFP Fiber Transceiver

To install an SFP fiber transceiver into SFP slot, the steps are:

1. Turn off the power to the device unit.

2. Insert the SFP fiber transceiver into the SFP slot. Normally, a bail is provided for every SFP transceiver.

Hold the bail and make insertion.

3. Until the SFP transceiver is seated securely in the slot, place the bail in lock position.

Dual Speed Support

The SFP slot supports 1000BASE-X based SFP fiber transceivers and 100BASE-FX based SFP fiber

-22-

transceivers.

Connecting Fiber Cables

LC connectors are commonly equipped on most SFP transceiver modules. Identify TX and RX connector
before making cable connection. The following figure illustrates a connection example between two fiber
ports:

Make sure the Rx-to-Tx connection rule is followed on the both ends of the fiber cable.

Network Cables

4. Manage the Switch

The switches provide the following methods to configure and monitor the switch as follows:

 Making out of band telnet CLI management via the console port
 Making in-band management via telnet CLI over TCP/IP network
 Making in-band management via web interface over TCP/IP network
 Making in-band SNMP management over TCP/IP network

4.1 IP Address & Password

The IP Address is an identification of the switch in a TCP/IP network. Each switch should be designated a new
and unique IP address in the network. The switch is shipped with the following factory default settings for
software management:

Default IP address of the switch: 192.168.0.2 / 255.255.255.0

The switch uses local authentication instead of RADIUS authentication with factory defaults.
Fixed Username: admin
Default password:

No password is required with factory default. However, the password is used for local authentication in
accessing to the switch via console, telnet and Http web-based interface. For security reason, it is
recommended to change the default settings for the switch before deploying it to your network.

4.6.1 SNMP Traps

In addition to the SNMP standard traps, the device is equipped with private OPA alarm traps.

The traps are:

- Alarm trap – Port TX power lower than the minimal value

- Alarm trap – Port TX power higher than the maximal value

- Normal trap – Port TX power back to normal (higher than the minimal value)

- Normal trap – Port TX power back to normal (lower than the maximal value)

5. Redundant Ring Applications

5.1 Auto Multi-Ring Technology

Auto Multi-Ring Technology was developed especially for switches connected in ring topology which needs
redundant support when any failure occurs in ring. For large network, more than one ring connections are very
common. Auto Multi-Ring Technology implementation can support more than one ring connection within a
switch. It is also able to work with RSTP support concurrently in the switch.

Some basic information is:

 Supports up to six rings in one switch
 Supports up to 100 member switches in one ring
 Provides fast response time than RSTP protocol
 Works with RSTP protocol concurrently within one switch

The following figure illustrates a configuration that three redundant rings and one RSTP ring hook on a main

redundant ring. Some switches support two redundant rings concurrently.

The following figure shows one switch is configured to support three redundant rings and one RSTP ring at the
same time.

5.2 Redundant Ring Applications with industrial standard RSTP protocol

It also can be done to support a ring connection using industrial standard RSTP function and establish a backup
path. In case that any link failure occurs, the backup path can link up immediately to recover the network
operation.
