 Network Hubs and Switches Guide

Hubs and switches function as a common connection point for the workstations, printers, file servers and other devices  that make up a network. The main difference between hubs and  switches is the way in which they communicate with the network.

What is a Hub?

A hub functions as the central connection point of a  network. It joins together the workstations, printers, and servers  on a network, so they can communicate with each other. Each hub has  a number of ports that connect it to the other devices via a network  cable.

How does a Hub work?

A hub is an inexpensive way to connect devices on a  network. Data travels around a network in packets and a hub forwards these data packets out to all the devices connected to its  ports.

As a hub distributes packets to every device on the  network, when a packet is destined for only one device, every other  device connected to the hub receives that packet. Because all the  devices connected to the hub are contending for transmission of data  the individual members of a shared network will only get a  percentage of the available network bandwidth. This process can slow  down a busy network.

A 10Base-T hub Ethernet Hub provides a total of 10  Mbit/sec of bandwidth, which all users share. If one person on the network is downloading a very large file, for example, little or no  bandwidth is available for other users. These users will experience  very slow network performance.

What is a Switch?

A switch is more sophisticated than a hub, giving you  more options for network management, as well as greater potential to  expand. A switch filters the data packets, and only sends the packet  to the port which is connected to the destination address of that  packet. It does this by keeping a table of each destination address  and its port. When the switch receives a packet, it reads the  destination address and then establishes a connection between the  source port and the destination port. After the packet is sent, the  connection is terminated.

What are the advantages of a Switch?

A switch provides higher total throughput than a hub because it can support multiple simultaneous conversations. For  example, when a 100Mbit/sec hub has five workstations, each receives  only 20Mbit/sec of the available bandwidth. When a 10/100Mbit/sec  switch is used every port on the switch represents a dedicated  100Mbit/sec path, so each workstation receives 100Mbit/sec of bandwidth.

Switches also run in full duplex mode, which allows  data to be sent and received across the network at the same time.  Switches can effectively double the speed of the network when  compared to a hub which only supports half duplex mode.

Why choose our Switches?

Switches improve the performance and efficiency of a network and  should be used when you:

  • Need to make best use of the available bandwidth
  • Have multiple file servers
  • Require improved performance from file servers, web servers or  workstations
  • Use high speed multi-media applications
  • Are adding a high speed workgroup to a 10Mbit/sec LAN
  • Plan to upgrade from 10 to 100Mbit/sec or Gigabit network

The standard features on all our N-Way switches are:

  • 10/100Mbit/sec Auto-Negotiation on all ports, the switch  automatically senses the speed of the attached device and  configures the port for the proper speed. This simplifies  deployment in mixed Ethernet and Fast Ethernet environments
  • Auto MDI/MDI-X auto-detects whether the connected cable type  is normal or cross-over
  • Full or Half Duplex operation

Which Switch do I need?

If you are setting up a home or small office network  an ideal solution is to use a switch with 5 to 8 ports. Switches can  be linked together as your network expands.

For a good entry level switch to meet this requirement  we recommend our 5  Port 10/100Base-TX  Ethernet N -Way Switch (Part No. 32981)  or our  8 Port 10/100Base-TX Fast Ethernet N-Way Switch (Part No.  32982)

Our compact 8 Port 10/100Base-TX Fast  Ethernet Switch features Auto MDI/MDI-X on all ports,  10/100Mbit/sec Auto-Negotiation, and full and half-duplex  modes and can be desktop or wall mounted.


If you require a larger switch with rackmount  capability choose our 16  Port 10/100 Base-TX Fast Ethernet N-Way Switch (Part No.  25020) or our 24  Port 10/100 Base-TX Fast Ethernet N-Way Switch (Part No.  25021).


These rackmount switches are the  perfect solution for expanding a 10/100  network.

Gigabit Ethernet Switches

Our GIGA N-Way Switches provide cost effective  scalability of the network by utilising the existing copper CAT5e  cabling environment. Connectivity is not sacrificed because the same  cabling is used for Ethernet, Fast Ethernet and Gigabit Ethernet.

These switches also incorporate VLAN technology. This  feature is accessed from a console port on the switch and provides  network administrators advanced configuration options and the  ability to set up LANs which function as separate, secure network segments.

Our 24  Port 10/100Base-TX + 2 Port 1000Base-T GIGA N-Way Switch (Part No. 25000) is ideal for linking backbone connections between servers and network switches.

24 Port 10/100Base-TX Switch with two  10/100/1000Base-T Gigabit Ethernet Ports with VLAN  technology.

Managed Switches

A managed switch allows the ports on the switch to be  configured, monitored, enabled and disabled. Switch management can  also gather information on a variety of network parameters, such as:

  • The number of packets that pass through each of its ports
  • What types of packets they are
  • Whether the packets contain errors
  • The number of collisions that have occurred

You should look for the following features on a  managed switch "

  • Gigabit Ethernet support
  • SNMP management and remote control capabilities
  • A management interface that can be accessed through an  internet browser
  • Auto-negotiation support which auto-senses the speed and  duplex capabilities of connected devices
  • Built-in expansion capability

Our Fully Managed SNMP 24 Port 10/100Base-TX + GIGA Expansion N-Way Switch  (Part No. 25030) is a high performance web-managed Layer 2 Switch  that provides 24 Fast Ethernet 10/100Mbps ports. The built-in  expansion slot can accommodate a number of different modules.  Optional Gigabit/Fast Ethernet modules can be copper or fibre based  and support 10/100/1000Base-T, 100Base-FX, and 1000Base-SX. This  switch is ideal for organisations wishing to create a new, or  upgrade their existing network infrastructure.

The switch features advanced SNMP (Simple Network  Management Protocol) management and remote control capabilities, and  supports an easy to use Layer 2 management interface that can be  accessed through an internet browser.

Fully managed SNMP 24 Port Fast Ethernet and  full Gigabit backbone support with remote  management.

Using a managed switch can reduce hidden costs by  using "

  • Switch and traffic monitoring to help head off problems before  they occur, reducing user downtime
  • Management tools that offer an intuitive graphical user  interface (GUI) that simplifies configuration and monitoring tasks
  • Management functions can be performed remotely using a web  browser or directly via a console connected to the switch
