Twisted Pair (TP) Cables

Cables can be shielded (screened) or unshielded. Cables must be Category 5

or above. 3Com recommends Category 5E or 6 cable for Gigabit

connections. The maximum length you can use is 100 m (328 ft).

Twisted Pair (TP) cable is very easy to use. To connect a TP cable, simply

slot the connector into the relevant RJ-45 Port. When a connector is fully

in, its latch locks into place. To disconnect the cable, push the connector’s

latch in and remove it.

When one end of a TP cable is connected to the Switch and the other end

is connected to the network interface card of a workstation or other

device, the Switch will automatically detect whether a straight-through or

crossover cable is being used and will compensate if required. The units

will then autonegotiate to determine the fastest possible link speed

between them. This may take a few seconds and the outcome will be

reflected in the LEDs on the front of the Switch.

If the equipment connected to the Switch does not support autonegotiation

or it has been disabled, it must be configured to operate in half duplex mode.

Expanding Your Network

You can increase the number of workstations and other devices that can

connect to your network by adding OfficeConnect gateways and switches.

You can connect a 10BASE-T, 100BASE-TX or 1000BASE-T OfficeConnect

unit to each port of the Switch.

The Switch has automatic MDI/MDIX functionality, and therefore does not

require the Uplink/Normal switch associated with some OfficeConnect

products. Simply plug in the cable, and the Switch will automatically detect

which wiring practice has been followed, and will compensate accordingly.

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 should be lit. If

they are not, check your connections.

CONNECTING WORKSTATIONS

Switching

When a network of repeater hubs is in operation, any information that is sent

by the workstation is passed around the whole network (regardless of the

destination of the information). This can result in a lot of unnecessary traffic that

can slow the network down. The Switch solves this problem because it "listens"

to the network and automatically learns what workstations can be reached

through its ports. It can then selectively pass on any information by transmitting

the traffic from the relevant port only. This operation is called "switching".

The Switch effectively divides up your network, localizing the network traffic and

passing on traffic as necessary. If you have any high performance workstations

that require a lot of bandwidth, connect them directly to the Switch.

Traffic Prioritization

The Switch has a built in feature to aid network performance at times of

excessive load. It is called Priority Queuing. When a packet is received, the Switch

will examine it to see if it has been priority encoded. If it has, the Switch will then

read the priority level and determine whether it should be directed through the

normal or high priority channel. This feature can be useful during excessive

loads, for example, when one type of traffic may require priority over another.

Connecting 10BASE-T/100BASE-TX/1000BASE-T Networks

The ports can each be connected to a 10BASE-T/100BASE-TX/1000BASE-T

network. If you have various connection speeds in your network, you can join

them together using the Switch allowing all your workstations to

communicate. For example, by connecting one of the ports to a server, all the

workstations connected to the server can communicate with devices connected

to the Switch, significantly increasing the size of your network.

Alternatively, if for example you use a 10BASE-T/100BASE-TX network and

want to improve network performance by introducing 1000BASE-T technology,

the Switch protects the investment in your existing workstations because it

maintains 10BASE-T/100BASE-TX connections to them.

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.

Perform these actions first:

• Ensure all network equipment is powered on.

• Power each piece of network equipment off, wait about five seconds and

then power each one on.

CAUTION: Do not power the Switch off and then immediately on. Wait

about five seconds between power cycles.

Check the following symptoms and solutions:

Power Status Logo not lit.

This is probably because the switch does not have power. Check the

following:

• Make sure the power lead from the power adapter is properly connected

and the cord is not damaged.

• Ensure the power adapter is correctly fitted into the power outlet socket

and that the socket switch is turned on if applicable.

• Ensure you are using only the 3Com power adapter supplied with the

switch.

If there is still no power, contact 3Com Technical Support and ask for

assistance

Only use the power adapter supplied with the Switch or a replacement

OfficeConnect power adapter. Do not use any other power adapter.

For reference, the part number for the power adapter supplied for your region is:

3C number Region

3C16760 US and Canada

3C16761 UK

3C16762 Europe and Middle East

3C16763 Australasia (except Japan and Korea)

3C16764 South Africa

3C16766 Japan

3C16767 Korea

Port Status LED not lit for a port that has a TP cable connected. After

connection, it may take several seconds for the Port Status LEDs to illuminate.

The Port Status LED should turn Blue, for each port that is connected.

If the Port Status LED is not lit after several seconds, ensure that the

connected device is powered on, that the TP cable is not damaged and that it

is correctly inserted at both ends.

You may find that a TP cable works when connected to the Switch, but does

not work if disconnected from the Switch and connected to another device.

This may be because the other device does not have the automatic MDI/MDIX

feature.

The Port Status LED is lit but the network performance of the switch

is poor. The switch supports full-duplex autonegotiation. If the connected

device does not support autonegotiation, ensure it is configured for half

duplex operation only.

PROBLEM SOLVING

Unit Connections

To connect OfficeConnect units (such as gateways or other switches) to

your Switch you need:

• One suitable Twisted Pair (TP) cable for each unit

3Com recommends Category 5E or 6 cable for Gigabit connections.

Workstation Connections

To connect workstations or other equipment (such as servers) directly to

your Switch, you need:

1 One adapter card for each workstation to be connected to a port on the

Switch. The adapter card must be capable of communicating at the

required connection speed. For example, if you want to use a Gigabit

connection, you must install a 1000BASE-T adapter card.

2 An operating system (for example Netware or Windows

95/98/Me/2000/XP) with network support configured, running on your

workstations.

3 One suitable Twisted Pair cable for each workstation.

HOW YOUR SWITCH CAN BE USED

Figure 3 Workstation connections

When positioning your Switch, ensure:

• It is out of direct sunlight and away from sources of heat.

• Cabling is away from power lines, fluorescent lighting fixtures, and

sources of electrical noise such as radios, transmitters and broadband

amplifiers.

• Water or moisture cannot enter the case of the unit.

• Air flow around the unit and through the vents in the side of the case is

not restricted. 3Com recommends you provide a minimum of 25 mm

(1 in.) clearance.

Using the Rubber Feet

Use the four self-adhesive rubber feet to prevent your Switch from moving

around on your desk, or when stacking with other units. Only stick the feet

to the marked areas at each corner on the underside of your Switch.

Wall Mounting

There are two slots on the underside of the Switch that can be used for wall

mounting. The Switch must be mounted with the LEDs facing upwards.

When wall mounting the unit, ensure it is within reach of the power

outlet

When wall mounting the unit, ensure that the rubber feet are not fixed

Mounting Instructions for Cement Walls
