12 CHAPTER 1: INTRODUCING THE OFFICECONNECT MANAGED SWITCH 9 AND SWITCH 9FX

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/

100BASE-TX/

1000BASE-T Port

The Switch has 8 auto-negotiating 10BASE-T/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.

The Switch 9 has one auto-negotiating 10BASE-T/100BASE-TX/1000BASE-T port configured as Auto MDI/MDI-X. 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.

Page 18

18 CHAPTER 1: INTRODUCING THE OFFICECONNECT MANAGED SWITCH 9 AND SWITCH 9FX

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.

Choosing a Suitable Site

The Switch is suited for use on a desktop, either free standing, stacked together with other units using the stacking clip, or mounted on a wall. Alternatively, the Switch can be placed in a wiring closet or equipment room, as an aggregator for other Hubs and Switches. A stacking kit containing one mounting clip is supplied with the Switch.

CAUTION: Ensure that the ventilation holes are not obstructed.

When deciding where to position the Switch, ensure that:

■ Cabling is located away from:

■ sources of electrical noise such as radios, transmitters and

broadband amplifiers.

■ power lines and fluorescent lighting fixtures

■ The Switch is accessible and cables can be connected easily.

■ Water or moisture cannot enter the case of the Switch.

■ Air flow is not restricted around the Switch or through the vents in the

side of the Switch. 3Com recommends that you provide a minimum of 25mm (1in.) clearance.

Page 23

Placing Units On Top of Each Other 23

■ Air temperature around the Switch does not exceed 50 °C (122 °F).

If the Switch is stacked with other OfficeConnect units its local air temperature may be greater than room ambient temperature.

■ The air is as free from dust as possible.

■ The unit is installed in a clean, air conditioned environment.

■ No more than four Switch units are placed on top of one another, if

the units are free-standing or stacked together with the stacking clip.

■ The Switch is situated away from sources of conductive (electrical)

dust, for example laser printers.

■ The AC supply used by the Switch is separate to that used by units

that generate high levels of AC noise, for example air conditioning

units and laser printers.

Placing Units On Top of Each Other

Using a Stacking Clip

If the Switch units are free-standing or stacked together with the stacking clip, up to four units can be placed one on top of the other. If you are mixing a variety of OfficeConnect Switch and Hub units, the smaller units must be positioned at the top.

If you are placing free-standing Switch units one on top of the other, you must use the supplied self-adhesive rubber pads to prevent the Switch from moving around on your desk, or when stacking with flat top OfficeConnect units. Apply the pads to the underside of each Switch, sticking one in the marked area at each corner.

Use a stacking clip when stacking your Switch with other curved OfficeConnect units. The stacking clip allows you to stack units neatly and securely.

CAUTION: You can stack up to a maximum of four units. Smaller units must be stacked above larger units.

To fit the clip:

1 Fit the clip across the top of the unit, as shown in Figure 5 (picture 1). 2 Align the fastening pieces over the slots found on each side of the unit. 3 Push the clip down gently to secure it, ensuring that the fastening pieces

snap into the slots on the unit.

Page 24

28 CHAPTER 2: INSTALLING 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

RJ-45 Cables

All of the RJ-45 ports on the Switch are Auto-MDIX, that is they have a 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 cable. See Table 7.

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).

Tab le 7 Cables required to connect the Switch to other devices if auto-negotiation is disabled

SFP Operation 29

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.

Approved SFP

Transceivers

Inserting an SFP

Transceiver

The following list of approved SFP transceivers is correct at the time of publication.

■ 3CSFP91 SFP (1000BASE-SX)

■ 3CSFP92 SFP (1000BASE-LX)

■ 3CSFP93 SFP (1000BASE-T)

To access the latest list of approved SFP transceivers for the Switch on the 3Com Corporation World Wide Web site, enter this URL into your internet browser:

http://www.3com.com

To be recognized as valid, the SFP transceiver must have the following characteristics:

■ 1000BASE-SX or 1000BASE-LX media type:

■ 1000BASE-SX SFP transceiver

Use this transceiver to connect the Switch directly to a multimode fiber-optic cable with fiber LC connectors.

■ 1000BASE-LX SFP transceiver

Use this transceiver to connect the Switch directly to a single-mode fiber-optic cable or to multimode fiber using a conditioned launch cable with fiber LC connectors.

Page 30

30 CHAPTER 2: INSTALLING THE SWITCH

■ 1000BASE-TX media type:

If the SFP transceiver is faulty, it will not operate within the Switch. See “Solving Hardware Problems” on page 53.

Use of non-3Com SFPs is not recommended. If the SFP transceiver is invalid it will not be recognized by the Switch.

Use the following sequence of steps to activate the SFP ports:

1 Hold the transceiver so that the (1000BASE-TX) RJ-45 connector or

(1000BASE-SX/LX) fiber connector is toward you and the product label is visible, as shown in Figure 6. Ensure the wire release lever is closed (in the upright position).

2 Gently slide the transceiver into the SFP port until it clicks into place.

CAUTION: SFP transceivers are keyed and can be properly inserted only one way. If the transceiver does not click when you insert it, remove it, turn it over, and reinsert it.

Use this transceiver to connect the Switch directly to a Category 5e twisted-pair cable with RJ-45 connectors.

3 Remove the plastic protective cover if fitted. 4 Connect the twisted-pair or fiber cable.

5 The 1000BASE-SX or 1000BASE-LX fiber transceiver connects to the

network using a duplex LC connector. The 1000BASE-TX transceiver connects to the network using an RJ-45 connector. If you are using a fiber transceiver, attach a male duplex LC connector on the network cable into the duplex LC connector on the transceiver. If using a 1000BASE-TX transceiver, attach an RJ-45 connector on the network cable into the RJ-45 connector on the transceiver.

6 Connect the other end of the cable to a device fitted with an appropriate

Gigabit Ethernet connection.

7 Check the Module Status LED on the front of the Switch to ensure that it

is operating correctly. Refer to “LEDs” on page 14 for more information.

If you wish to remove a 3Com transceiver (it is not necessary to power-down your Switch):

1 Disconnect the cable from the transceiver. 2 Move the wire release lever downwards until it is pointing toward you. 3 Pull the wire release lever toward you to release the catch mechanism;

the transceiver will then easily slide out.

Page 32

32 CHAPTER 2: INSTALLING THE SWITCH

The above procedure will release a 3Com SFP transceiver. To release a transceiver from another manufacturer see the documentation supplied with your SFP transceiver.

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 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 covers the following topics:

■ Setting Up Overview

■ Manually Configuring IP Information

■ Viewing Automatically Configured IP Information

■ Methods of Managing a Switch

■ Setting Up Command Line Interface Management

■ Setting Up Web Interface Management

■ Setting Up SNMP Management

■ Default Users and Passwords

34 CHAPTER 3: SETTING UP FOR MANAGEMENT

Setting Up Overview

This section gives an overview of what you need to do to get your Switch set up and ready for management when it is in its default state. The whole setup process is summarized in Figure 7. Detailed procedural steps are contained in the sections that follow. In brief, you need to:

■ Configure IP information manually for your Switch or view the

automatically configured IP information

■ Prepare for your chosen method of management

CAUTION: To protect your Switch from unauthorized access, you must change all default passwords as soon as possible, even if you do not intend to actively manage your Switch. For more information on default users and changing default passwords, see “Default Users and Passwords” on page 48.

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 through the “Manually Configuring IP Information” section on page 37.

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

Page 36

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 Information” section on page 40.

Preparing for Management

Once your Switch’s initial set up is complete you can set up your chosen management method as described in “Methods of Managing a Switch” 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 37

Manually Configuring IP Information

Connecting to the

Console Port

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).

To set up your Switch manually you can make a connection to the console port (this example describes a local connection to the console port, rather than a remote one via a modem). You can do this whilst the Switch is offline, that is, before you connect the Switch to a network, or whilst the Switch is online, that is, connected to a network.

Pre-requisites

■ A workstation with terminal emulation software installed, such as

Microsoft Hyperterminal. This software allows you to communicate

with the Switch via the console port directly.

■ Documentation supplied with the terminal emulation software.

■ The RJ-45 to RS-232 cable supplied with the Switch.

You can find the pin-out diagram for this cable in

■ You need to have the following so that you can manually set up the

The initial set up of your Switch is now complete and the Switch is ready for you to set up your chosen management method. See “Methods of Managing a Switch” on page 43.

If you do not intend to use the command line interface via the console port to manage the Switch, you can disconnect the serial cable and close the terminal emulator software.

Viewing Automatically Configured IP Information

Using 3Com Network

Supervisor

If you allow the Switch to automatically configure its own IP information you need to discover and view the IP information before you can begin to manage the Switch. You can discover the IP information in two ways:

■ Using 3Com Network Supervisor — This application will auto-discover

the Switch and display the automatically allocated IP information assigned to the Switch.

■ Connecting to the Console Port — Connect a workstation to the

console port of the Switch using the RJ-45 to RS-232 cable. You can then view the IP information automatically assigned to the Switch using the command line interface (CLI).

You can use the 3Com Network Supervisor application provided on the CD-ROM that accompanies your Switch to discover the automatically allocated IP information.

1 Connect your Switch to the network. 2 Power-up the Switch and wait for two minutes. 3 Launch 3Com Network Supervisor and run the Auto-discovery wizard.

3Com Network Supervisor will auto-discover the new Switch and display the IP information that has been automatically allocated to the Switch.

Most DHCP servers allow static IP addresses to be configured so that you know what IP address the Switch will be given. Refer to the documentation that accompanies your DHCP server.

application software.

To manage your Switch using an SNMP network management application, you need to specify SNMP community strings for the users defined on the Switch. You can do this using the Web management interface — refer to the command line interface section of the “Switch Management Interface Reference Guide” for more information.

If you intend to manage the Switch using the web interface or the command line interface, or to change the default passwords, you need to log in with a valid user name and password. The Switch has two default user names, and each user name has a different password and level of access. These default users are listed in Table 9.

CAUTION: To protect your Switch from unauthorized access, you must change the two default passwords as soon as possible, even if you do not intend to actively manage your Switch

PROBLEM SOLVING

This chapter helps you to diagnose and solve problems you may have with the operation of your Switch. There is also an explanation of IP addressing.

The topics covered are:

■ Solving Problems Indicated by LEDs

■ Solving Hardware Problems

■ Solving Communication Problems

■ Solving Software Upgrade Problems

■ Recovering from a Lost Password

If you experience a problem that is not listed here, it may be included in the Support section of the Switch Management Interface Reference Guide on the CD-ROM that accompanies your Switch.

For Technical Support information, see Appendix D.

Page 52

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.

Page 53

Solving Hardware Problems 53

■ 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:

■ Fibers are broken.

■ Auto-negotiation differs at either end (a link appears at the ‘fixed’

end and not at the auto-negotiation end).

A PoE device is connected and yet the PoE Status LED does not light

Refer to “A device is connected to the Switch but power is not being supplied” on page 53 for troubleshooting procedures.

Solving Hardware Problems

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

Page 54

54 CHAPTER 4: PROBLEM SOLVING

■ Check that the port has not had a power limit imposed upon it.

enough power subsequently becomes available the port will be powered.

Solving Communication Problems

If you experience communication problems with the Switch, ensure that:

■ The Switch IP address has been configured as described in Chapter 3.

■ 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.

Page 55

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:

Solving Software Upgrade Problems

Recovering from a Lost Password

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.

You can upgrade the management software of the Switch by using the System > Control > Software Upgrade operation in the Web Interface, or

system control softwareUpgrade command in the

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.

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.

Page 56
