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.
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.
CHAPTER 2: INSTALLING THE SWITCH ■ 1000BASE-TX media type: Use this transceiver to connect the Switch directly to a Category 5e twisted-pair cable with RJ-45 connectors. 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.
SFP Operation 31 Figure 6 Inserting a SFP Transceiver 12 3.5AVDC MAX Product label Wire release lever Suitable slot on Switch 9 FX 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.
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.
3 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.
CHAPTER 3: SETTING UP FOR MANAGEMENT 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.
Setting Up Overview 35 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).
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.
Manually Configuring IP Information Manually Configuring IP Information Connecting to the Console Port 37 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).
CHAPTER 3: SETTING UP FOR MANAGEMENT Connecting the Workstation to the Switch 1 Connect the workstation to the console port using a standard null modem cable as shown in Figure 8. Figure 8 Connecting a workstation to the Switch via the console port Switch Workstation (with terminal emulation software installed) Standard Null Modem Cable Console Port Connection To connect the cable: a Attach the RJ-45 to RS-232 cable to the console port on the Switch.
Manually Configuring IP Information 39 Setting Up the Switch with IP Information You are now ready to manually set up the Switch with IP information using the command line interface. 1 The command line interface login sequence begins as soon as the Switch detects a connection to its console port. If the login prompt does not begin immediately, press Return a few times until it starts. If you have not logged onto the Switch before, you will be prompted to enter a new password.
CHAPTER 3: SETTING UP FOR MANAGEMENT 4 Enter the IP address, subnet mask, and gateway IP address for the Switch. The screen displays a summary of the information entered. If using the gettingStarted command you will then be prompted to enter system information, change passwords, and then given the option to carry out advanced configuration. The initial set up of your Switch is now complete and the Switch is ready for you to set up your chosen management method.
Viewing Automatically Configured IP Information Connecting to the Console Port 41 Alternatively, you can view the automatically configured IP information via the command line interface (CLI) through a connection to the console port. (This example describes a local connection to the console port, rather than a remote one via a modem.) Pre-requisites ■ A workstation with terminal emulation software installed, such as Microsoft Hyperterminal.
CHAPTER 3: SETTING UP FOR MANAGEMENT 2 Open your terminal emulation software and configure the COM port settings to which you have connected the cable. The settings should be set to match the default settings for the Switch, which are: ■ Any of the following baud rates: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 ■ 8 data bits ■ no parity ■ 1 stop bit ■ no hardware flow control Refer to the documentation that accompanies the terminal emulation software for more information.

4 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.
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.
Solving Hardware Problems ■ The quality of cable is satisfactory. ■ Auto-negotiation settings are the same at both ends. 53 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).
CHAPTER 4: PROBLEM SOLVING enough power subsequently becomes available the port will be powered. ■ Solving Communication Problems Check that the port has not had a power limit imposed upon it. If you experience communication problems with the Switch, ensure that: ■ The Switch IP address has been configured as described in Chapter 3.
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.
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.
