INTRODUCTION Welcome to the world of networking with 3Com® . In the modern business environment, communication and sharing information is crucial. Computer networks have proved to be one of the fastest modes of communication but until recently, only large businesses could afford the networking advantage. The OfficeConnect® product range from 3Com has changed this, bringing networks to the small office.
CREATING YOUR NETWORK Dual Speed Switch 5 plus—Front 5

Dual Speed Switch 16 plus—Rear Power Adapter socket 10/100BASE-TX ports Only use the power adapter that is supplied with this OfficeConnect Switch. Do not use any other adapter. Use suitable TP cable with RJ-45 connectors. You can connect the OfficeConnect Switch to any workstation or OfficeConnect hub that has a 10BASE-T, 100BASETX or 10/100BASE-TX port. Each port is capable of auto-negotiating for 10 Mbps or 100 Mbps operation.
whether it should be directed through the normal or high priority channel. This feature can be useful, for example, during excessive loads when one type of traffic may require priority over another. The Switch is configured to to comply with VLAN priority tagged frames and IP TOS / DSCP priority encoded frames.
Connecting 10BASE-T and 100BASE-TX Networks Worksation Connections The 10/100 ports can each be connected to either a 10BASE-T or 100BASE-TX network. If you have both types of network, you can join them together using the Switch allowing all your workstations to communicate. Alternatively, if you use 10BASE-T and want to improve network performance by introducing 100BASE-TX technology, the Switch protects your existing workstations because it maintains 10BASE-T connections to them.
To fit another unit: Stacking the Units Together 1 Rest the second unit on top of the clip and align it with the front of the unit below. The Rubber Feet 2 Press down gently on the unit to secure it onto the clip, The four self-adhesive rubber feet prevent your switch from moving around on your desk. Only stick the feet to the marked areas at each corner of the underside of your switch if you intend to place the unit directly on top of the desk. Do not fix the feet if you are going to use the clip.
Positioning Your Switch Securing Your Switch When installing your Switch, ensure: There are two slots on the underside of the OfficeConnect Switch that can be used for wall mounting. It is recommended that you mount the Switch with the LEDs facing upwards to prevent dust entering the cooling vents. ■ It is out of direct sunlight and away from sources of heat.
This may take a few seconds and the outcome will be reflected in the LED’s on the front of the Switch. Connecting Workstations and Other Equipment to Your Switch If the equipment connected to the Switch does not support auto-negotiation or if it has been disabled, it must be configured to operate in half duplex mode. WARNING: Please read the ‘Important Safety Information’ section before you start.
Checking Unit Connections When you have connected all your units, power on the units and the Switch. The Port Status LEDs for the ports you have used on both the units and the Switch should be on. If they are not, check your connections. Figure 4 Correct Connections for an OfficeConnect Hub OfficeConnect Switch There is no uplink/normal push switch that is usually associated with OfficeConnect products.
PROBLEM SOLVING The Switch has been designed to aid you when detecting and solving possible problems with your network. These problems are rarely serious; the cause is usually a disconnected or damaged cable, or incorrect configuration. If this section does not solve your problem, contact your supplier for information on what to do next. Please refer to pages 5, 6 and 7 'Creating your Network' for a full description of the LED's.
Network loop — Examine your connections and remove the loop. Each piece of equipment needs only one connection to your Switch. Broadcast frames — Some pieces of network equipment operate by sending out broadcast frames regularly. Please refer to the documentation that accompanies the piece of network equipment.
NETWORKING TERMINOLOGY A segment is the length of cable connected to a port. A Network is a collection of workstations (for example, IBM-compatible PCs) and other equipment (for example, printers), connected for the purpose of exchanging information or sharing resources. Networks vary in size, some are within a single room, others span continents. Packets are the units of information your workstations and other equipment send to each other over the network.
Priority Queuing is the ability of a network to give and maintain certain throughput levels for different applications depending on the priority assigned to that application. At excessive loads a packet with a higher priority will take a greater precedence over a lower prioritised packet. Automatic MDI / MDIX this feature automatically detects which wiring practice that has been followed with regard to the TP cable, ie if the TP cable is a 'straight through' wired cable or a 'crossover' wired cable.
