CHAPTER 1: INTRODUCING THE OFFICECONNECT MANAGED SWITCH 9 AND SWITCH 9 FX
About the Switch
The Switch is a 10/100 Mbps Ethernet Switch, which consists of:
8 10BASE-T/100BASE-TX ports
■
and either:
■
One 10BASE-T/100BASE-TX/1000BASE-T (10/100/1000) port or
One 100BASE-FX LC port and one SFP port
■
The 100BASE-FX and SFP port is a combination port. When an SFP
module is inserted it has priority over the 100BASE-FX port of the same
number. The corresponding 100BASE-FX port is disabled when an SFP
module is present.
The Switch supports Power over Ethernet on ports 1, 2, 5 and 6. If you
plug in a compatible (IEEE 802.3af compliant) device, it will be
automatically detected and power supplied to it. Power over Ethernet is
enabled on these ports by default.

10BASE-T/ The Switch has 8 auto-negotiating 10BASE-T/100BASE-TX ports
100BASE-TX Ports configured as Auto MDI/MDI-X. These ports automatically provide the
appropriate connection. The default state for 10/100 Mbps ports is
auto-negotiation enabled, where the speed, duplex and flow control
modes are negotiated.
Alternatively, you can manually set these ports to 10BASE-T half duplex,
10BASE-T full duplex, 100BASE-TX half duplex, 100BASE-TX full duplex
and manually enable or disable flow control. The maximum segment
length is 100 m (328 ft) over Category 5 twisted pair cable.
If you disable auto-negotiation, Auto MDI/MDI-X will also be disabled.
The Switch will supply up to 15.4W of power through ports 1, 2, 5 and 6
in conformance to the 802.3af specification. The Switch incorporates a
PoE Status LED on the front panel, which indicates when power is being
delivered to a device connected to one of these ports.
10BASE-T/ The Switch 9 has one auto-negotiating
100BASE-TX/ 10BASE-T/100BASE-TX/1000BASE-T port configured as Auto MDI/MDI-X.
1000BASE-T Port This port automatically provides the appropriate connection. The default
state for the 10/100/1000 Mbps port is auto-negotiation enabled, where
the speed, duplex and flow control modes are negotiated.
Alternatively, you can manually set these ports to 10BASE-T half duplex,
10BASE-T full duplex, 100BASE-TX half duplex, 100BASE-TX full duplex
or 1000BASE-T full duplex and manually enable or disable flow control.
The maximum segment length is 100 m (328 ft) over Category 5 twisted
pair cable.
If you disable auto-negotiation, Auto MDI/MDI-X will also be disabled.
SFP Port The Switch 9 FX has one SFP (Small Form Factor Pluggable) port that
supports Gigabit Ethernet short-wave (SX) or long-wave (LX) fiber-optic
SFP transceivers, or Gigabit Ethernet 1000BASE-TX SFP transceivers. This
offers you the flexibility of using SFP transceivers to provide connectivity
between the Switch and a 1000 Mbps core network or to create a high
capacity aggregated link between two workgroups.
When using fiber-optic SFP transceivers, the only state for this port is
auto-negotiation enabled. As the speed and duplex modes are fixed by
the media type, only the flow control is negotiated with the link partner.
18
CHAPTER 1: INTRODUCING THE OFFICECONNECT MANAGED SWITCH 9 AND SWITCH 9 FX
When an SFP module is inserted it has priority over the 100BASE-FX port.
The corresponding 100BASE-FX port is disabled when an SFP module is
present.
100BASE-FX Port The Switch 9 FX has one 100BASE-FX LC port. This is a 100 Mbps
fiber-optic port that can use standard multi-mode fiber-optic cable of up
to 2 kilometers (1.2 miles). It uses the standard duplex LC connector that
allows both the transmit and the receive fibers to be connected in the
same space as an RJ-45 port.
When an SFP module is inserted it has priority over the 100BASE-FX port.
The corresponding 100BASE-FX port is disabled when an SFP module is
present.
Console Port The console port allows you to connect a terminal and perform local
out-of-band management. The console port uses an RJ-45 to DB-9 null
modem cable (supplied with the Switch) and is set to 19200 baud, 8 data
bits, no parity and 1 stop bit.
The default configuration automatically detects any of the following baud
rates: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200.
However, you must set the baud rate on your management device to
19200 baud if you want to view all the system initialization messages.
Power Socket The power adapter supplied with the Switch automatically adjusts its
power setting to any supply voltage in the range 100-240 VAC. Only use
the adapter provided with the Switch.

For further information about Power Over Ethernet, refer to “Power
Management and Control” in the Switch Implementation Guide supplied
on the CD-ROM that accompanies your Switch. Power over Ethernet
management is available using the web interface or the command line
interface (CLI).
Choosing the Correct All of the RJ-45 ports on the Switch are Auto-MDIX, that is they have a
RJ-45 Cables cross-over capability. The port can automatically detect whether it needs
to operate in MDI or MDIX mode. Therefore you can make a connection
to a port with a straight-through (MDI) or a cross-over cable (MDIX).
The Auto-MDIX feature only operates when auto-negotiation is enabled.
If auto-negotiation is disabled, all the Switch ports are configured as
MDIX (cross-over). If you want to make a connection to another MDIX
port, you need a cross-over cable. Many ports on workstations and
servers are configured as MDI (straight-through). If you want to make a
connection to an MDI port, you need to use a standard straight-through
WARNING: The Switch supports Power over Ethernet on rear ports 1, 2,
5 and 6. These ports should only be used for Ethernet wiring within the
same building. The SFP and 100BASE-FX ports of the Switch 9 FX can be
used for Ethernet wiring between buildings.
3Com recommends that you use Category 5e twisted pair cable — the
maximum segment length for this type of cable is 100 m (328 ft).

to a grounded port before connecting network equipment. If you do not,
the cable’s Electrostatic Discharge (ESD) may damage the Switch’s port.
You can create a grounded port by connecting all wires at one end of a
UTP cable to an earth ground point, and the other end to a female RJ-45
connector located, for example, on a Switch rack or patch panel. The
RJ-45 connector is now a grounded port.
SFP Operation
The following section describes the use of an SFP transceiver in your
Switch.
SFP transceivers are hot-insertable and hot-swappable. You can remove
them from and insert them into any SFP port without having to power
down the Switch.

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 management 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 therefore the overall performance of your network.
This chapter explains the initial set up of the Switch and the different
methods of accessing the management software to manage a Switch. It

intend to actively manage your Switch. For more information on default
users and changing default passwords, see “Default Users and
IP Configuration You can use one of the following methods to allocate IP information to
your Switch (essential if you wish to manage your Switch across the
network).
Manual IP Configuration
You can choose to configure the IP information yourself. The Switch
remembers the information that you enter until you change it again or
set the configuration method to Automatic.
You should use the Manual IP configuration method if:
■
■
■
you do not have a DHCP server on your network, or
you want to remove the risk of the IP address ever changing, or
your DHCP server does not allow you to allocate static IP addresses.
(Static IP addresses are necessary to ensure that the Switch is always
allocated the same IP information.)
For most installations, 3Com recommends that you configure the Switch
IP information manually. This makes management simpler and more
reliable as it is not dependent on a DHCP server, and eliminates the risk of
the IP address changing.
If you wish to manually enter IP information for your Switch, work
Automatic IP Configuration
By default the Switch tries to configure itself with IP information without
requesting user intervention. It tries to obtain an IP address from a DHCP
server on the network.
It may take up to 5 minutes for your Switch to obtain an IP address after
it has been powered up.
When using automatic IP configuration it is useful if the Switch is issued
the same IP address on each occasion, otherwise you will not know what
the IP address is and it will be difficult to manage. Most DHCP servers
36
CHAPTER 3: SETTING UP FOR MANAGEMENT
allow fixed IP addresses to be configured so that you know what IP
address will be allocated to the Switch. Refer to the documentation that
accompanies your DHCP server.
For a detailed description of how automatic IP configuration operates,
please refer to the Implementation Guide on the CD-ROM that
accompanies your Switch or on the 3Com Web site.
You should use the automatic IP configuration method if:
■
your network uses DHCP to allocate IP information, or
■
flexibility is needed. If the Switch is re-deployed onto a different
subnet, it will automatically reconfigure itself with an appropriate IP
address, instead of you having to manually reconfigure the Switch.
If you use the automatic IP configuration method, you need to discover
the automatically allocated IP information before you can begin
management. Work through the “Viewing Automatically Configured IP
Preparing for Once your Switch’s initial set up is complete you can set up your chosen
on page 43.
For detailed information about the specific web interface operations and
command line interface commands and problem solving, refer to the
“Switch Management Interface Reference Guide” on the CD-ROM that is
supplied with the Switch or on the 3Com Web site.

Manually
Configuring IP
Information
You can manually configure the Switch IP information in the following
way:
■
Connecting to the console port — Connect a workstation using a
console cable to the console port of the Switch. You can then
manually enter IP information using the command line interface (CLI).
Connecting to the To set up your Switch manually you can make a connection to the console
Console Port port (this example describes a local connection to the console port, rather

For Technical Support information, see Appendix D.
52
CHAPTER 4: PROBLEM SOLVING
Solving Problems
Indicated by LEDs
If the LEDs on the Switch indicate a problem, refer to the list of suggested
solutions below.
The Power LED does not light
Check that the power cable is firmly connected to the Switch and to the
supply outlet. If the connection is secure and there is still no power, you
may have a faulty power cord or an internal fault. Check the power cord
by:
■
testing it in another device
■
connecting a working power cord to the ‘problem’ device
Then contact your supplier for advice.
On powering-up, the Alert LED remains orange
This indicates that a port has failed and has been automatically disabled.
You can verify this by checking that the Port Status LED is flashing
Green/Yellow. This could be due to loop back failure. If a port fails, the
Switch passes its Power On Self Test and continues to operate normally.
On Powering up, the Alert LED flashes orange while the Switch is starting
up. This is normal and does not indicate any of the above conditions.
A Port Status LED is flashing green/yellow
The port has failed and has been automatically disabled. The Switch
passes its Power On Self Test and continues to operate normally, even if
one or more ports are disabled.
A link is connected and yet the Status LED for the port does not
light
Check that:
■
The Switch and the device at the other end of the link (or cable) are
connected securely.
■
The devices at both ends of the link are powered-up.
Solving Hardware Problems

■
■
The quality of cable is satisfactory.
Auto-negotiation settings are the same at both ends.
Auto-negotiation problems will occur with 10BASE-T, 100BASE-TX or
1000BASE-T where auto-negotiation is disabled and incorrect cables
are being used (cross-over or straight).
Auto-negotiation problems will occur with fiber if:

In the rare event of your Switch unit experiencing a hardware failure,
refer to the list of suggested solutions below.
A device is connected to the Switch but power is not being
supplied
If power is not being supplied to a device connected to the Switch, you
should do the following checks:
■
Check that the device is compliant with the 802.3af standard ref. [18].
The Switch will only supply power through rear panel ports 1, 2, 5,
and 6 to 802.3af compliant devices.
■
Check that the power budget for the Switch has not been exceeded.
If the power budget has been exceeded, then by default, the powered
device connected to the Power over Ethernet port with the lowest
priority port will lose power. However, if all the devices connected to
the Switch have equal priority levels, then the port with the highest
number will lose power.
By default the Switch will allow a device to receive power as long as
the Power over Ethernet power supply has 18 watts spare in its power
budget. If this much power is not available the device will not be
powered (unless it has a higher priority than existing powered ports)
and a Power over Ethernet fault will be reported for that port. If
54
CHAPTER 4: PROBLEM SOLVING
enough power subsequently becomes available the port will be
powered.
■
Check that the port has not had a power limit imposed upon it.
Solving
If you experience communication problems with the Switch, ensure that:
Communication
Problems
■
■
If the Switch is separated from your management application by a
router, ensure that the default gateway IP address within the Switch is
the same as the IP address of the router.
■
The Switch’s IP address has been entered correctly in your network
management application (such as 3Com Network Supervisor).
The following is a brief overview of IP addressing, and how to obtain a
registered IP address.
IP Addressing
To be managed correctly, each device on your network (for example a
Switch or Hub) must have a unique IP address. IP addresses have the
format n.n.n.n where n is a decimal number between 0 and 255. An
example IP address is 192.168.100.8.
The IP address is split into two parts:
■
■
The first part (‘192.168.100’ in the example) identifies the network on
which the device resides
The second part (‘.8’ in the example) identifies the device within the
network
The natural subnet mask for this example is 255.255.255.0.
If your network has a connection to the external IP network, that is, you
access the Internet, you must apply for a registered IP address.
How do you obtain a registered IP Address?
The IP registration system ensures that every IP address used is unique; if
you do not have a registered IP address, you may be using an identical
address to someone else and your network will not operate correctly.
Solving Software Upgrade Problems
55
The Internet Assigned Numbers Authority is the organization responsible
for supplying registered IP addresses. The following contact information is
correct at time of publication:
World Wide Web site: http://www.iana.org/
If your IP network is internal to your organization only, that is, you do not
access the Internet, you may use any arbitrary IP address as long as it is
not being used by another device on your network. 3Com suggests you
use addresses in the range 192.168.0.0 to 192.168.255.255 with a
subnet mask of 255.255.255.0.
These suggested IP addresses are part of a group of IP addresses that
have been set aside specially for use ‘in house’ only.
Solving Software
Upgrade Problems
You can upgrade the management software of the Switch by using the
System > Control > Software Upgrade operation in the Web Interface, or
the system control softwareUpgradecommand in the
command line interface. For details on these options, refer to the
Management Interface Reference Guide supplied in HTML format on the
CD-ROM that accompanies your Switch.
If you have problems with your software upgrade, refer to the Problem
Solving section in the Management Interface Reference Guide.
Recovering from a
Lost Password
The password recovery mechanism assumes that the Switch is located in
a physically secure area, and access is restricted to legitimate network
administrators. The first time the Switch is powered on, you will be
prompted to set a password for administrator access. Record the
password and store it in a safe place.
If you forget the password, follow this recovery procedure:
■
■
Connect a workstation to the Switch’s console port.
Use a terminal emulation software package such as Microsoft
Hyperterminal to connect to the console interface on the Switch.
■
Log onto the Switch with the reserved user name “recover” and the
password “recover” to place it into password recovery mode.
56
CHAPTER 4: PROBLEM SOLVING
■
■
■
Reset power to the Switch within 30 seconds by removing the power
cord from the Switch and then re-connecting it.
When the Switch restarts, enter a new password for the
Administrator.
Log onto the Switch with the user name “admin” and the new
password you just configured.
