2 INSTALLING THE SWITCH This chapter contains supplemental information on setting up your Switch 4500. These details are intended to be read together with the printed documents that accompany your switch.
CHAPTER 2: INSTALLING THE SWITCH Important Steps Before Proceeding Connecting a Redundant Power Supply to your Switch 4500 PWR Before proceeding, make sure to access the Switch 4500 information on 3Com’s Web site at www.3Com.com and: ■ Read the document entitled “3Com Switch Family Safety and Regulatory Information,” which contains information on how to set-up your Switch 4500 and all the safety and regulatory warnings.
Connecting a Redundant Power Supply to your Switch 4500 PWR 25 with the 3Com Power-over-Ethernet (PoE) network switches. In order to meet the IEEE 802.3af (PoE) specification, the -48V output must be isolated from earth (ground) and meet the isolation requirements in that specification.
CHAPTER 2: INSTALLING THE SWITCH WARNING: Any RPS must be approved as a SELV output in accordance with IEC 60950-1/UL 60950-1/EN 60950-1. WARNING: The characteristics of the Switch 4500 DC supply input are given in Appendix B on page 91. The Switch 4500 PWR units can be powered in three different ways: ■ AC Mains only — does not offer any power redundancy. If the AC mains supply or the AC power supply fail, the Switch will power off.
Connecting a Redundant Power Supply to your Switch 4500 PWR 27 Table 6 Switch Power Inputs Power Input before Power Input after User Intervention User Intervention Correct Response AC mains and RPS RPS only The unit remains powered by the RPS. AC mains and RPS AC mains only The unit is powered by the AC mains. PoE dropped on all ports, however the unit does not reset. PoE restarts powered by the remaining power from the AC mains. PoE ports will be dropped depending on their preset priority level.
CHAPTER 2: INSTALLING THE SWITCH Table 7 Power Availability Rectifiers 1 2 3 4 5 6 No Rectifier Redundancy 1500W 3000W 4500W 6000W 7500W 9000W N+1 Rectifier Redundancy - 1500W 3000W 4500W 6000W 7500W The -48V DC power distribution provides the mechanism to connect to the Switch 4500 PWR. The distribution consists of a number of circuit breakers and connection terminals for the positive (common) and negative -48V outputs.
Connecting a Redundant Power Supply to your Switch 4500 PWR 29 WARNING: Ensure that the circuit breaker in the RPS is in the open (off) position when connecting the cable to the RPS and the cable and connector to the Switch. WARNING: You must ensure that the positive terminal on the Switch is connected to the positive (common) terminal of the RPS and that the negative terminal on the Switch is connected to the negative (circuit breaker) terminal of the RPS.
CHAPTER 2: INSTALLING THE SWITCH The -48V DC power will take priority over the AC mains and will power the Switch if it is connected. Connecting the Earthing Cable Use the earthing cable that accompanies your Switch if the length is suitable. Alternatively use the earthing cable specification as defined in Appendix B on page 91. The earthing cable is only required if the Switch is powered by the RPS only. The recommended cable length should not exceed 3 metres (9.84 feet).
Connecting a Redundant Power Supply to your Switch 4500 PWR 31 network cable is required to provide both power and network connectivity. ■ Increased Reliability — a device powered by a PoE Switch will be able to take advantage of the facilities available to the Switch. The Switch can be fitted with a redundant power supply or uninterruptible power supply, increasing its uptime. The Switch supports resistor detection according to IEEE 802.3af and pre-standard detection methods.
CHAPTER 2: INSTALLING THE SWITCH The Power-up Sequence Powering-up the Switch 4500 The following sections describe how to get your Switch 4500 powered-up and ready for operation. Use the following sequence of steps to power-up the Switch. 1 Plug the power cord into the power socket at the rear of the Switch. 2 Plug the other end of the power cord into your power outlet. The Switch powers-up and runs through its Power On Self Test (POST), which takes approximately one minute.
The Power-up Sequence Choosing the Correct Cables for the 1000BASE-X SFP Ports 33 The 1000BASE-SX SFP transceiver supports a direct connection to a multi-mode fiber-optic cable. The 1000BASE-LX SFP transceiver supports a direct connection to single-mode and multi-mode fiber-optic cables.
CHAPTER 2: INSTALLING THE SWITCH SFP Operation Approved SFP Transceivers The following sections describes how to select and use an SFP transceiver in an SFP port. The following list of approved Gigabit Ethernet SFP transceivers is correct at the time of publication. ■ ■ ■ ■ ■ 3CSFP91 SFP (1000BASE-SX) 3CSFP92 SFP (1000BASE-LX) 3CSFP93 SFP (1000BASE-T) 3CSFP93-4500 SFP (1000BASE-T) 3CSFP97 SFP (1000BASE-LH70) The 3CSFP93-4500 is approved for use in the Switch 4500 only.
SFP Operation Inserting an SFP Transceiver 35 Use the following sequence of steps to activate the SFP ports: SFP transceivers are hot-insertable and hot-swappable. You can remove them from and insert them into an appropriate SFP port without having to power down the Switch. 1 The SFP transceiver is keyed and there is only one way in which it can be installed correctly. It is not necessary to power-down your Switch.
CHAPTER 2: INSTALLING THE SWITCH Packing and Shipping the Switch 4500 This section describes how to correctly package your Switch 4500 should you need to return the Switch to 3Com. WARNING: The unit should be packaged safely to ensure that you do not invalidate the repair. Follow these steps to ensure that you package your unit correctly: 1 Orientate your Switch so that the back panel is on the left side (looking down at the top of the unit) as shown in Figure 9.
3 SETTING UP FOR MANAGEMENT To make full use of the features offered by your 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.
CHAPTER 3: SETTING UP FOR MANAGEMENT Methods of Managing a Switch Command Line Interface Management To manage your Switch you can use one of the following methods: ■ Command line interface management ■ Command line interface management using SSH ■ Web interface management ■ SNMP management Each Switch has a command line interface (CLI) that allows you to manage the Switch from a workstation, either locally via a console port connection (see Figure 10), or remotely over the network (see Figure
Methods of Managing a Switch Command Line Interface Management using SSH Web Interface Management 39 The Switch 4500 supports Secure Shell version 2.0 (SSHv2.0), allowing secure access to the Command Line Interface of the Switch. If you use SSH to administer your Switch and the network traffic is intercepted, no passwords or configuration information will be visible in the data. To securely administer the Switch using the Command Line Interface you need a third party SSH client.
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 14. Detailed procedural steps are contained in the sections that follow.
Setting Up Overview 41 CAUTION: To protect your Switch from unauthorized access, you must change all three 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 56. 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 For a detailed description of how automatic IP configuration operates, refer to the Configuration Guide available on 3Com’s Web Site at www.3com.com. You should use the automatic IP configuration method if: ■ your network uses DHCP to allocate IP information, or ■ flexibility is needed.
Manually Configuring IP Information Manually Configuring IP Information Connecting to the Console Port 43 You can manually configure the Switch IP information in the following ways: ■ 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 a front panel port — connect a workstation using an Ethernet cable to a front panel port of the Switch.
CHAPTER 3: SETTING UP FOR MANAGEMENT Connecting the Workstation to the Switch 1 Connect the workstation to the console port using the console cable as shown in Figure 15. Figure 15 Connecting a Workstation to the Switch via the Console Port Workstation (with terminal emulation software installed) Switch Console Port Connection Console Cable To connect the cable: a Attach the RJ-45 connector on the cable to the console port of the Switch.

Save the configuration in the User View. For information on the lost password procedure please refer to the Configuration Guide that is supplied with your Switch.
CHAPTER 3: SETTING UP FOR MANAGEMENT
4 CREATING A STACK This chapter contains the information you need to create a stack. It covers the following topics: How To Interconnect Units ■ How To Interconnect Units ■ Guidelines For Interconnecting Units ■ Unit Numbering within the Stack Up to eight 3Com Switch 4500 units can be interconnected to create a stack and then treated as a single manageable unit with one IP address. You can interconnect your Switches to create a stack using a standard 1000 Mbps Ethernet connection.
CHAPTER 4: CREATING A STACK As with all Switch 4500 CLI commands, the format for entering a portspecific command is x/y/z, where x = unit number, y = module number (in the case of the Switch 4500 this will always be 0), z = port number. 3 Connect the stack-enabled ‘up’ port on one Switch 4500 unit to the stack-enabled ‘down’ port on another Switch 4500 unit using the appropriate connection method for your Switch. 4 Save all configuration settings.
Unit Numbering within the Stack ■ 61 When a port is operating in stack mode it will no longer be configurable in the normal way, that is, you cannot control port features such as auto-negotiation, VLANs, static addresses, STP, Aggregated Links, Resilient Links, and so on. However, it is possible to specify the stack VLAN.
CHAPTER 4: CREATING A STACK Renumbering only occurs when the stack is next power cycled if the units are configured to auto-number. The unit LEDs will display the unit number in the stack, from 1 to 8. If you are having problems, refer to “Solving Stack Formation Problems” on page 69.
5 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 and upgrading software.
CHAPTER 5: 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 PWR 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. Firstly, check the power cord by: ■ testing it in another device.
Solving Hardware Problems 65 Auto-negotiation problems will occur with 10BASE-T or 100BASE-T where auto-negotiation is disabled and incorrect cables are being used (cross-over or straight) Auto-negotiation problems will occur with fiber if: ■ ■ ■ Solving Hardware Problems The Receiver (RX) and Transceiver (TX) cable connectors are swapped Fibers are broken Auto-negotiation differs at either end (a link appears at the ‘fixed’ end and not at the auto-negotiation end) In the rare event of your Switch uni
CHAPTER 5: PROBLEM SOLVING 3 Power cycle the unit. To do this, remove and reconnect the AC mains supply. If the unit has no AC main supply, remove and reconnect the DC RPS supply. 4 If another fan failure warning message is generated via the Command Line Interface or the Web interface, return the unit to 3Com. Unit fails, no SNMP fan failure message is received 1 Power cycle the unit. To do this, remove and reconnect the AC mains supply.
Solving Communication Problems Solving Communication Problems 67 If you experience communication problems with the Switch, ensure that: ■ The Switch IP address and Management VLAN ID has been configured. ■ 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.
CHAPTER 5: PROBLEM SOLVING 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 Stack Formation Problems Solving Stack Formation Problems 69 If you are having problems with correctly forming a stack, first ensure that Spanning Tree is enabled. If it is enabled, do the following: 1 Power off all units in the stack. 2 Check all the cable connections in the stack. 3 Check the ports have been enabled as stack ports. 4 Power on all units in the stack.
