2.    Introduction to 9 Port NWay Switching Hub 

 

2.1 General Description 

 

This device is a powerful, high-performance Ethernet / Fast Ethernet Switch with 

two fiber uplink ports. Twisted pair ports are capable of 10 or 100Mbps auto-negotiation 

operation (N-Way). 100Mbps according to the 100Base-FX standard are supported on 
the fiber interface. The SWH-2109F is an ideal solution for micro-segmenting large 

networks into smaller sub-networks for overall improved performance, so enabling the 

most demanding bandwidth multimedia and imaging applications. Moreover, the 

10/100Mbps auto-sensing capability provides an easy way in which to move from a 

10Mbps to a 100Mbps network.   

Compared with shared 10Mbps or 100Mbps networks, this N-Way switch delivers a 

dedicated 10/100Mbps connection to every attached client with no bandwidth congestion 
problems. Store-and-forward switching modes guarantee low latency and fast data 

transmission. Full-duplex mode allows the simultaneous transmission and reception of 

frames without the risk of collisions as well as a doubling of the network bandwidth.   

 

For network connection: 

 

The switching hub can use the following types of cabling: 
 

„

 

10BASE-T Category 3, 4 or 5 UTP/STP 

 

„

 

100BASE-TX Category 5 UTP/STP 

 

Fiber Optic: 

50/125, 62.5/125, or 100/140

µ

m multimode 

 

 

 

8.3/125, 8.7/125, 9/125 or 10/125

µ

m single mode 

 

Category 5 cable is preferred to be used with this product in structured wiring 

environments. This will ensure correct operation of all ports at 10Mbps or 

100Mbps.

The auto-negotiation feature of the switching hub allows port 1 to port 8 running at 

one of the following four operation modes: 

1. 100Mbps full-duplex 

2. 100Mbps half-duplex 

3. 10Mbps full-duplex 

4. 10Mbps half-duplex 

 

Port F1 and F2 can be used as fiber uplink ports for connecting to another fiber 

optic device or operation as redundant function. You can easy extend the distance from 

2,000m to 100,000m by multimode or single mode fiber cable. 

 

Warning:    The RJ-45 ports are shielded data sockets. They can not be used as 

telephone sockets. Only R-J45 plugs are allowed to connect these sockets. 

 

2.3.1 System LEDs 

System LED indicators are located on the front panel for showing the operating 

status of the whole device. 

         

2.3.1.1

 

Power LED 

This indicator lights green when the hub is receiving power; otherwise, it is off. 

 

2.3.2 Port LEDs 

Port LED indicators are located on the front panel for showing the operating status 

of each port. 

 

2.3.2.1 Speed LED 

The Speed LED indicates the link speed of each port. If the LED lights green then 

the connection speed is 100Mbps, off for 10Mbps.   

 
2.3.2.2 Link/Act LED 

Every port has a Link/Activity LED. Steady green (link state) indicated that the port 

has good linkage to its associated device. Flashing green indicates that the port is 

receiving or transmitting data between its associated devices.   

 

If the port is connected but the Link/Activity LED is dark, check the following items: 

 
1. The switching hub and the connected device’s power are on or not 

2. The port’s cable is firmly seated in its connectors in the switching hub and in the 

associated device. 

3. The connecting cable is good and with correct type   

4. The connecting device, including any network adapter is functioning. 

 

From the Speed LED and Link/Activity, we could judge the connection speed as 
following:

FDX/COL LED 

 

A collision occurs when two stations within a collision domain attempt to transmit 

data at the same time. Intermittent flashing amber of the collision LED is normal; the 

contending adapters resolve each collision by means of a wait-then-retransmit algorithm. 
Frequency of collisions is an indicator of heavy traffic on the network.   

 

If the FDX/COL light green which means the port is under full-duplex operation or 

dark for half-duplex mode. The following table is a summary of Port LEDs.

another switch with crossover cable.   

 

3.1.2.4 Switch to Switch Connections with Fiber Cable 

In making a switch to switch connection, you could use port 7to port 8 to connect 

another switch with fiber cable. And the distance can be extending from 2,000m to 

100,000m with multimode or single mode cable. 

 

5.2

 

Installing Redundant Fiber Port 

The SWH-2109F built in one pair redundant fiber port function in port F1 and port 

F2. In the event of a failure in the primary connection (port F2), a fully redundant 
secondary connection (port F1) is made available to the failed connection.   

             

3.2.1

 

Redundant Installation 

Due to software function is complete and could use switch configuration option set 

up fiber redundant and F1 and F2 link fiber cable. You can monitor redundant function 

operation status from front panel LED indication. 

 
 

NOTE: 

Strong recommend user must link SWH-2109F with “Redundant 

Function” device if want to setup SWH-2109F under Fiber Redundant function.

4.  Switch Operation 

 

5.1

 

MAC Address Table and Learning 

 

The switching hub is implemented with a MAC address table which is composed of 

many entries. Each entry is used to store the address information of network nodes on 
the network, including MAC address, port ID, etc. The information is the most important 

base to do packet filtering and forwarding. 

 

When one packet comes in from any port, the switching hub will learn the source 

address, port ID, and the other related information in address table. Therefore, the 

content of the MAC table will update dynamically.   

 

5.2

 

Filtering and Forwarding 

 

When one packet comes in from any port of the switching hub, it will check the 

destination address besides the source address learning. The hub will look up the 

address table for the destination address. If not found, this packet will be forwarded to all 

the other ports except the port which this packet comes in. If found, and the destination 

address is located at different port from this packet comes in, the packet will be 
forwarded to the port where this destination address is located according to the 

information of address table. But, if the destination address is located at the same port as 

this packet comes in then this packet will be filtered.   

     

4.3 Store and Forward 

 

Store-and-forward is one kind of packet-forwarding methodology. As a 

store-and-forward switching hub, it will store the complete packet in the internal buffer 
and do the complete error checking before transmitting to the network. Therefore, no 

error packets will disturb the network. It is the best choice when a network needs 

efficiency and stability.
