OfficeConnect

®

Managed Gigabit Switch. This

high quality, Gigabit Ethernet Switch is an easy, efficient way of creating or expanding
an existing network and managing it centrally. The Switch’s Gigabit ports provide sup-
port for bandwidth intensive applications, and allow high speed connections to servers,
and to the rest of the network. An example configuration is shown in Figure 1.

GreenConnect

Your OfficeConnect Gigabit Switch employs a number of initiatives to ensure your
product uses the least amount of power possible:

1. High Efficiency Power Adapter

The Power Adapter is a model specially designed to meet the Energy Star

require-

ments for operating efficiency and also very low standby power when not connected
to the switch. These two features ensures your power adapter now uses substantially
less power than a conventional linear adapter.

2. Energy Saving Modes

Your OfficeConnect Gigabit Switch employs the latest technology to minimise the
amount of power it consumes. 
When a port on the switch is not connected to a cable, or the link partner is turned
off or removed, the switch reduces the power on that port until it is connected again. 
Also the switch detects the length of cable connected to its port and optimizes the
power on the port to reach the end device. Thus for shorter cables lengths it will
reduce the power output thereby achieving further reduction in power consumption.

You can be confident that your Switch will be taking the least amount of power but
still providing the performance that you have come to expect from OfficeConnect.

The Switch is compact and attractively designed for desktop use. It can be used with
other units in the OfficeConnect family, which include Cable/DSL gateways, wireless
devices, Fast Ethernet and Gigabit Ethernet switches. The OfficeConnect family is a
fully integrated system, enabling you to share computer resources, and take advantage
of new technologies as your network grows.

Safety Information

WARNING: Please read the ‘Important Safety Information’ section in the
Support and Safety Information sheet before you start.

VORSICHT: Bitte lesen Sie den Abschnitt ‘Wichtige Sicherheitsinformationen’
sorgfältig durch, bevor Sie das Gerät einschalten.

AVERTISSEMENT: Veuillez lire attentivement la section "Consignes 
importantes de sécurité" avant de mettre en route.

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 elec-

trical 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 flat top OfficeConnect 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 mount-
ing. The Switch must be mounted with the LEDs facing upwards. When wall mount-
ing 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

1  Make two holes 150 mm (5.9 in.) apart and insert two nylon or similar screw

anchors that are suitable for the wall construction.

2  Fix two suitable screws into the anchors, leaving their heads 3 mm (0.12 in.) clear of

the wall surface. The screws should be at least 30 mm (1.2 in.) long,

3  Remove any connections in the Switch and locate it over the screw heads. When in

line, gently push the Switch on to the wall and move it downwards to secure.

Mounting Instructions for Wood Walls

1  Make two holes 150 mm (5.9 in.) apart.
2  Fix two suitable screws directly into the wall, leaving their heads 3 mm (0.12 in.)

2. SETTING UP FOR MANAGEMENT

Your Switch can operate in its default state, that is, you can install it and it will work
straight away (plug-and-play). However, to make full use of the features offered by the
Switch, and to change and monitor the way it works, you have to access the manage-
ment software that resides on the Switch. This is known as managing the Switch.
Managing the Switch can help you to improve the efficiency of the Switch and there-
fore the overall performance of your network.

IP Configuration

When the switch is powered up and connected to a network, the switch will obtain an
address from the DHCP server. If there is no DHCP server available, the switch will use
a default IP address of 169.254.xx.yy, where xx and yy are the last two bytes of the
MAC address. This default IP address is also printed on the label attached to the
underside of your switch.

Before you can manage your switch, you will need to determine it’s IP address to allow
a web browser to connect to it. You can do this either by connecting your workstation
to the console interface using the cable supplied, or using the 3Com Switch Detect
application that can be found on the CD that was supplied with the Switch.

Please follow the instructions below to determine and/or configure the IP address of
your switch.

Using the Console Interface

1. Connect the DB-9 to RJ-45 serial cable between your workstation (to it’s COM port)

and the Switch. Take care not to connect it to a data port on the Switch.

2. Using a terminal emulator program, for example HyperTerminal, connect to the

appropriate COM port on the workstation and ensure the following parameters are
set: 38400 baud, 8 data bits, no parity, 1 stop bit and no flow control.

3. If the Switch is not already powered up, power it up now and wait for the boot up

sequence to complete.

4. When the boot up sequence is completed, you will be presented with a login

prompt. The default username is admin. No password is required.

5. To show the IP address the switch is using, enter IP status and press Return. The

switch will display the IP address the switch is using. This address can now be used
in your preferred web browser to connect to the Switch User Interface. Use the
same username to log in.

6. If you want to manually assign an IP address, enter the following commands:

IP dhcp disable

and press Return

IP Setup <IP Address> <ipmask> <gateway>

and press Return

For example: IP Setup 192.168.1.2 255.255.255.0 192.168.1.1
You can now direct the web browser at the 192.168.1.2 address.

Using the 3Com Switch Detect Application

1. On the computer that is connected to your Switch (either directly or on a network

that is on the same subnet), insert the CD-ROM into its CD drive. If you have
autorun

enabled, you will be presented with a menu showing the contents of the

CD-ROM. 

2. Select the 3Com Detect Application link to install the utility. Follow the onscreen

instructions. 

3. If the auto-run program does not start, you should browse to your CD-ROM drive,

go to the /switch detect directory and double click on setup.exe. Follow the
prompts that will take you through the installation process. 

4. Once installed, the 3Com Switch Detect Application can be accessed from the

Windows Start/Programs list. 

5. When the 3Com Detect application starts, you will be see the Welcome Screen (see

below).

6. If the computer has multiple network adapters, select the adapter that connects the

computer to the network or Switch, click "Next."

7. You will then be offered the choice of searching the same subnet that your PC is on

for a connected switch (default), or specifying an IP range. Note that specifying a
large range may take some time for the search to complete.

8. Once your Switch or Switches have been located, you will be presented with a list.

Select the switch to which you want to connect and click on "Open." Your default
Web browser will open and connect to the home page of the Switch.

3 CONNECTING WORKSTATIONS

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 con-
nector 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 connect-
ed 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. The Switch has auto-
matic MDI/MDIX functionality. Simply plug in the cable and the Switch will automati-
cally detect which wiring practice has been followed and will compensate accordingly.

4 PROBLEM SOLVING

The Switch has been designed to aid you when detecting and solving possible prob-
lems with your network. These problems are rarely serious; the cause is usually a dis-
connected 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 LED 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:

Power LED lit but Status LED illuminated yellow.

This indicates that the switch is receiving power, but for some reason the switch is not
operational. This is most likely due to a problem with the operational software in the
unit not loading correctly. 

Refer to the diagnostic messages displayed on the command line interface (CLI) to
help identify the problem. If the software is corrupted, you can re-load the software
from the CLI. Please follow the instructions found in the User Guide for this Switch
which can be found on the on the CD which is supplied with your Switch or which
can be downloaded from www.3Com.com.

If a software reload does not resolve the issue, contact 3Com Technical Support and
ask for assistance

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 Green or Yellow, 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.
