To combine technologies as your network grows, install the CoreBuilder 9400 in your network. Some key features of the CoreBuilder 9400 system: ■ This system exhibits no packet loss or delays even under maximum network traffic on its 24 Gigabit Ethernet ports. CoreBuilder 9400 Intelligent Switch The CoreBuilder 9400 system delivers full line rate switching among all 24 Gigabit Ethernet ports. The system has the following ports (shown in Figure 1 on page 15): ■ 12 1000BASE-SX (MMF) ports with SC connectors ■ 12 GBIC ports that can accept 1000BASE-LX or 1000BASE-SX GBIC transceivers The system supports full-duplex mode on all Gigabit Ethernet ports and up to 32,000 MAC addresses. To deliver even higher performance rates among switches, the system supports trunking, which allows you to group up to six Gigabit Ethernet ports into a single multigigabit connection for a maximum of 12 trunks per system. High-density Gigabit Ethernet configuration ■ Trunking of Gigabit Ethernet ports This system allows you to configure up to six Gigabit Ethernet ports into a single multigigabit connection for a maximum of 12 trunks per unit. ■ Trunking links and Spanning Tree Protocol support The CoreBuilder 9400 protects against cable and equipment failures with Spanning Tree Protocol and trunking links. ■ Failure protection To protect your network, this system has an optional second power supply. 12 CHAPTER 1: SYSTEM AND SETUP OVERVIEW ■ Resilient links Resilient links technology protects your network against an individual link or device failure by providing a secondary backup link that is inactive until it is needed. ■ Manageability The CoreBuilder 9400 provides full support for VLANs and RMON-1, as well as a roving analysis port through SNMP management. System Management The CoreBuilder 9400 system includes integrated management to provide fault tolerance and maximum network availability. This management is accessible in three ways: ■ CoreBuilder 9400 Administration Console ■ Standard network management applications based on SNMP, such as 3Com’s Transcend applications, Sun’s SunNet Manager, HP’s OpenView, and IBM’s NetView AIX applications ■ Web Management suite of applications, with forms for many management tasks, charts and wizards to help you configure and monitor your system, and online Help (separately installed) give you instant information about your configuration choices. Network Configuration Example This section discusses one way to place the CoreBuilder 9400 in your network. Speeding Up Server Access To centralize your servers for easier service and support, use a configuration like the one shown in Figure 3. Suppose that all of your organization’s servers are located in that physical space. These servers must support a large number of clients that are distributed throughout the organization’s campus. The clients are switched Fast Ethernet desktops. First, you can multiplex the traffic from each group of desktop clients into one higher-bandwidth stream (trunk) through a SuperStack II Switch 3900. Each SuperStack II 3900 can, in turn, pass its traffic along to a CoreBuilder 9400, which multiplexes the traffic into Gigabit Ethernet streams for the servers. This architecture eliminates bottlenecks caused by each Fast Ethernet device as it vies for access to the server. You can also use the CoreBuilder 9400 for many other applications, such as to consolidate LAN backbones or to provide more flexible trunking configurations.

For cabling instructions, see Chapter 3. 3 CABLING COREBUILDER 9400 PORTS This chapter describes how to cable your CoreBuilder® 9400 system for connection to the network. It gives an overview of cabling and describes how to cable: ■ Gigabit Ethernet ports ■ Console port ■ Out-of-band management port Fiber Safety Precautions The CoreBuilder 9400 system uses lasers in its fiber optic ports. To ensure your safety, comply with the following precautions. When all of your Gigabit Ethernet and system network connections are complete, see Chapter 4. WARNING: The fiber optic lasers used in this system meet the regulatory requirements for casual exposure to the eye. As with any source of bright light, however, 3Com recommends that you do not look into the laser light source. If you are staging the system, you do not need to connect it to the network at this point. See Chapter 4 to start your system before you cable it. IEC 825, Class 1 Laser Devices are for connection only to Class 1 Laser Devices. MMF and SMF fiber optic interfaces use lasers. Overview of Cabling The CoreBuilder 9400 system is a Gigabit Ethernet switch with this fixed configuration: ■ Twelve 1000BASE-SX ports ■ Twelve 1000BASE GBIC ports (LX or SX transceivers) CLASS 1 LASER PRODUCT 20 CHAPTER 3: CABLING COREBUILDER 9400 PORTS Cabling Gigabit Ethernet Ports ■ Use 50-micron MMF fiber with a modal bandwidth specification of 400 MHz*km for distances of up to 500 m (1645 ft). ■ Use 50-micron MMF fiber with modal bandwidth specification of 500 Mhz*km for distances of up to 550 m (1805 ft). Before you cable the system, consider this Caution. CAUTION: You may not want to connect the network cables before you power on the system (chapter 4) if you need to configure trunks, resilient links, or the Spanning Tree Protocol (STP). To avoid bridge loops, configure trunks, resilient links, and STP using the Administration Console before you connect the cables and after you power up the system. See the Command Reference Guide and the Implementation Guide for your system. Guidelines for Gigabit Ethernet Cabling For all Gigabit Ethernet cabling, keep the ports and connectors free of dust. See “Cleaning Dirty Fiber Optic Ports and Connectors” on page 40 for details. Recommended Distances for 1000BASE-SX Ports or Transceivers When you cable 1000BASE-SX ports or transceivers, verify that the length of the fiber cable from the system to any attached device does not exceed these recommended distances: ■ ■ Use 62.5-micron MMF fiber with a modal bandwidth specification of 160 MHz*km for distances of up to 220 m (722 ft). Use 62.5-micron MMF fiber with a modal bandwidth specification of 200 MHz*km for distances of up to 275 m (902 ft). Recommended Distances for 1000BASE-LX Transceivers When you cable 1000BASE-LX transceivers, verify that the length of the fiber cable from the system to any attached device does not exceed these recommended distances: ■ Use 62.5-micron MMF fiber with a modal bandwidth specification of 160 MHz*km for distances of up to 550 m (1805 ft). ■ Use 62.5-micron MMF fiber with a modal bandwidth specification of 200 MHz*km for distances of up to 550 m (1805 ft). ■ Use 50-micron MMF fiber with a modal bandwidth specification of 400 MHz*km for distances of up to 550 m (1805 ft). ■ Use 50-micron MMF fiber with a modal bandwidth specification of 500 MHz*km for distances of up to 550 m (1805 ft). ■ Use 9-micron SMF fiber for distances of up to 10 km (6.2 mi). The specification requires and specifies 5 km (3.1 mi). Use a conditioned launch cable to connect the 1000BASE-LX transceiver to multimode fiber. Using this cable ensures reliability over the maximum 550 m distance. Cabling Gigabit Ethernet Ports Cabling 1000BASE-SX Ports To cable one of the 1000BASE-SX ports with SC connectors: Figure 5 shows cabling for the 1000BASE-SX ports. Figure 5 Cabling the 1000BASE-SX Port 1 Read the Caution at the beginning of “Cabling Gigabit Ethernet Ports” earlier in this chapter. 2 Remove the dust covers and save them for future use. 3 Examine the port and connector pair for dust. Verify that nothing blocks the light transmission between the port and its connectors.

You can turn the system off only by removing the power cord from the power source or from the system itself. 2 On the back panel, slide the power supply latch up and plug the power cord into the power receptacle. 3 Plug the other end of the power cable into a power outlet. 4 If you want add an additional power supply, repeat step 2 and step 3 for the second power supply. 30 CHAPTER 4: SYSTEM POWER UP Power-up Diagnostics The CoreBuilder 9400 system runs diagnostic software at power up. This software verifies that the system works before you add it to the network. Fault LED Activity ■ No Light — System diagnostics have been successfully completed and the system is operational. ■ Solid or Blinking Yellow — The system has failed diagnostics, or some other operational error has occurred. If any component fails during power-up diagnostics, the system fails to power up. During power up, the system and port status LEDs provide information about the CoreBuilder 9400 system. See Figure 1 in Chapter 1 for the location of the LEDs. To view error messages that are displayed during power-up diagnostics, connect a terminal, workstation, or PC that has terminal emulation to the system’s Console port. See Chapter 3. System Diagnostics This section describes the LEDs that provide information about the system as a whole. Power LED Activity ■ Green — The system is on; the system is running or has run diagnostics. ■ No Light — The system has no power; no diagnostics are running. See Chapter 6 for troubleshooting information. Gigabit Ethernet Port Diagnostics This section summarizes the information displayed by the port LEDs. Packet LED Activity ■ No light — Data is not being transmitted or received by the port. ■ Blinking yellow — Data is not being transmitted or received by the port. ■ Yellow — Data is passing through the port. Status LED Activity ■ No light — The port is off-line. ■ Blinking green — The port is online but disabled. ■ Green — The port is online and enabled. See Chapter 6 for troubleshooting information. System Checks System Checks After the system has successfully completed the power-up diagnostics, check the items in Table 5 to verify that the system is operating correctly. If you discover abnormal conditions, see Chapter 6. Table 5 System Power-Up Checklist Check Description Power-up error messages If there is a problem during power-up, the messages are displayed in the Administration Console connection through the Console port. Normal LED activity When the power-up diagnostics are running, the LEDs light in a certain pattern as described in the “Power-up Diagnostics” section. After you properly cable the system and the system successfully completes the power-up diagnostics, look for the following normal LED activity: System: Power LED = Green Fault LED = Not lit Each port: Pckt status LED = Yellow Stat status LED = Green If an LED does not light or shows a color different from the one indicated here, see Chapter 6 for information about the cause of the problem. 31 Next Step: Software Configuration Your CoreBuilder 9400 system is shipped from the factory with the software installed and IEEE 802.1d Spanning Tree Protocol disabled. To configure your system for your particular networking environment (including setting up SNMP), you must first establish management access. See Chapter 5. 32 CHAPTER 4: SYSTEM POWER UP 5 QUICK SETUP FOR MANAGEMENT ACCESS For more complete network management, use an external SNMP-based management application such as 3Com’s Transcend Enterprise Manager for UNIX or Windows or another network management application. This chapter provides easy instructions for configuring the CoreBuilder® 9400 system for management access. When you decide how you want to manage your system, follow the configuration instructions for your preferred type of management access. The Web Management suite of applications allows you manage your system using a Web browser. It consists of WebConsole (including Configuration Wizards), DeviceView, Performance, and the HTML-based Help system. About CoreBuilder 9400 System Management To configure and manage your CoreBuilder 9400 system, you can use one of several applications after you establish a connection: ■ CoreBuilder 9400 Administration Console How Do You Want to Manage the System? ■ Other SNMP-based network management applications ■ Web Management suite of applications You can manage your system locally through a terminal connection or through the network with an IP connection. Table 6 describes the access mechanisms. The Administration Console is a character-oriented, menu-driven user interface for administering the system. You can access the Administration Console out-of-band, using either the 10BASE-TX port or the Console port, or in-band, using one of the Gigabit Ethernet ports through the IP network protocol. For more detailed information, see the Command Reference Guide. Table 6 Management Access Mechanisms Access Mechanism Allows you to Using Terminal Connect directly to the Administration Console and stay attached across system reboots Console port Modem Connect remotely to the Administration Console Console port 34 CHAPTER 5: QUICK SETUP FOR MANAGEMENT A CCESS Table 6 Management Access Mechanisms Modem Connection Access Mechanism Allows you to IP ■ Use a dedicated network to Ethernet 10BASE-TX manage your network out-of-band port out-of-band. Access the Administration Console in-band with the rlogin or Telnet commands. ■ Access the Administration Console in-band with the rlogin or telnet commands. Or use an external SNMP management application to communicate with the CoreBuilder 9400 SNMP agent. One of the Gigabit Ethernet ports assigned to an IP interface Use the Web Management interface. Netscape Navigator or Internet Explorer ■ Using To access the system through a modem, establish a connection between your workstation and the Console port. When you configure the external modem from the Administration Console menu system, the Console appears to be directly connected to the external modem. See the Command Reference Guide for more information. Use the Console port for either a terminal connection or a modem connection. IP Management Interface An IP interface is the connection between the CoreBuilder 9400 system and a subnetwork. Use the IP interface to manage the system in two ways: ■ These mechanisms are described more fully in the next sections. Terminal Connection Direct access through the Console port is often preferred because it allows you to remain on the system during system boots. A Macintosh or PC attachment can use any terminal emulation program for connecting to the Console port. A workstation attachment under UNIX can use the emulator TIP or you can attach a terminal. For more details, see the documentation that is shipped with your terminal emulation program. In-band — Through a Gigabit Ethernet port You can use this port for switching and managing the system simultaneously. This method decreases the total bandwidth available on the port for switching. ■ Out-of-band — Through the 10BASE-TX port that is located to the left of the Console port You can use this port only to manage the system, not for switching network traffic. Managing your system out-of-band conserves all available bandwidth for the Gigabit Ethernet ports. Also, if network problems exist, you can manage the system from a different network. See the Implementation Guide for more information on in-band and out-of-band management. Initial Management Access With an IP interface and either the in-band or the out-of-band port, you use the rlogin or Telnet commands to access the Administration Console using TCP/IP from a host computer. You can also use the IP interface to manage the system with an external management application via SNMP or the Web Management software. 35 Use this menu to change the Console port baud setting for the terminal or to configure your system for another management access mechanism. Changing the Console Port Baud Setting To change the baud setting of the Console port: 1 From the top level of the Administration Console, Initial Management Access The first time that you access your system, you connect through the Console port using a terminal or terminal emulator. These are the default settings for this port: 9600 baud, 8 bits, 1 stop bit, No parity. When you access the Administration Console using the Console port, you see this prompt: Select access level (read, write, administer): 1 At the prompt, enter: administer 2 At the password prompt, press Return. The following menu appears: Menu options: -----------------------------------------------------system - Administer system-level functions management - Administer system management interface ethernet - Administer Ethernet ports bridge - Administer bridging/VLANs ip - Administer IP snmp - Administer SNMP analyzer - Administer Roving Analysis script - Run a script of console commands logout - Logout of the Administration Console Type ? for help. -----------------------------------------------------Select menu option: enter: system serialPort serialPortMode 2 At the prompt, if the default value shown in brackets is modem, enter console. Otherwise, press Return. 3 Enter baudRate. 4 Enter 9600 for the Console port. The system supports these baud settings: 19200, 9600, 4800, 2400, and 1200. The system displays this message: Enter new value (1200-19200) [1200]: 9600 Error setting baud rate to 9600. Baud rate will change upon next connection. 36 CHAPTER 5: QUICK SETUP FOR MANAGEMENT A CCESS Configuring the IP Interface These instructions include information on how to define an IP interface through which you can manage your CoreBuilder 9400 system. An IP interface contains the following parameters: ■ ■ IP address — This address, which is specific to your network, is used to manage the system. The IP address defines both the number of the network to which the interface is attached and its host number on that network. Subnet mask — This 32-bit number uses the same format and representation as an IP address. The subnet mask determines which bits in the IP address are interpreted as the network number, which as the subnet number, and which as the host number. Each IP address bit that corresponds to a 1 in the subnet mask is in the network and subnet part of the address. Each IP address bit that corresponds to a 0 is in the host part of the IP address. In-band Management To set the IP interface parameters to manage the system in-band: 1 From the top level of the Administration Console, enter: ip interface define 2 Enter the IP address of the interface. 3 Enter the subnet mask of the subnetwork to which the interface is to be connected. 4 Enter the interface type: vlan 5 Enter the VLAN interface index For more detailed instructions on assigning interface parameters, see the Command Reference Guide. Out-of-band Management To set the IP interface parameters to manage the system out-of-band: 1 From the top level of the Administration Console, enter: ip interface define 2 Enter the IP address for the out-of-band port. 3 Enter the subnet mask of the subnetwork to which the interface is to be connected. Press Return to accept the default subnet mask. 4 Enter the interface type: system For more detailed instructions on assigning interface parameters, see the Command Reference Guide. 6 TROUBLESHOOTING THE SYSTEM This chapter explains how to troubleshoot certain problems with the CoreBuilder® 9400 system. It covers: ■ Getting Additional Help ■ Diagnosing Problems ■ Cleaning Dirty Fiber Optic Ports and Connectors Getting Additional Help If you experience system problems that are not addressed in this chapter, contact your network supplier or 3Com Technical Support.

When the problem is corrected, the LED lights green. If a GBIC port is affected, the transceiver may not be properly seated or is defective. If the LED still does not light, contact your network supplier or 3Com Technical Support. 39 40 CHAPTER 6: TROUBLESHOOTING THE SYSTEM Cleaning Dirty Fiber Optic Ports and Connectors Fiber optic transceivers are sensitive optical devices. Handle them carefully. If dirt collects on a fiber optic lens, the associated LED may not light. You may also notice degradation in port performance, indicated by adverse changes in the Gigabit Ethernet statistics on a port. To prevent dust from collecting on the fiber optic lens, keep the dust covers on the ports at all times when they are not in use. WARNING: The fiber optic lasers used in this system meet the regulatory requirements for casual exposure to the eye. As with any source of bright light, however, 3Com recommends that you do not look into the laser light source. To clean a fiber optic lens, take these steps: 1 Remove any accumulated dust or debris from the port or connector by blowing across all surfaces with a canned air duster. Compressed gas is recommended, such as Chemtronics’ Ultrajet or the Triangle Tool Group’s Liqui-Tool Dust-A-Way. Do not use commercial compressed air or “house air” because of the risk of oil contamination. 2 Reconnect the cable to the port to check whether dusting has corrected the problem. 3 Gently wipe the ports with a lint-free, nonabrasive, nonadhesive swab. Microswabs by Texwipe are recommended. 4 Gently wipe the connectors with a lint-free, nonabrasive wipe or pad. Texwipe pads are recommended. Avoid touching any connector surface after you clean the connectors.

The topics covered in this appendix: ■ General Safety Requirements ■ Wiring Closet Recommendations ■ ■ Wiring Closet Recommendations The cabling system plan at your facility probably covers most wiring closet concerns. 3Com also recommends that you check these items: ■ Verify that your wiring closet meets all of the requirements in your facility cabling plan. Distribution Rack Requirements, if you mount one or more CoreBuilder 9400 systems in a distribution rack ■ Verify that your wiring closet and your facility meet all state, local, and country building and wiring codes. Building and Electrical Codes ■ Be sure that your system is easily accessible for installation and service. ■ Provide adequate overhead lighting for easy maintenance. ■ Be sure that all wiring closet doors have locks to prevent unauthorized access. ■ Assign wiring closet identification numbers using architectural location codes or some type of floor-grid matrix. ■ Select a vinyl floor covering for your wiring closet. Concrete floors accumulate dust; carpets can cause static electricity. ■ Be sure that the wiring closet floor is flat and level. If you are using distribution racks and the floor is not level, bolt the racks to the floor to prevent them from tipping over. General Safety Requirements For safe operation, your site must meet these general safety requirements: ■ Environmental requirements. See Appendix A and “Wiring Closet Recommendations” for details. Pay special attention to temperature and humidity. ■ All building and electrical codes for your city and country. See relevant “Building and Electrical Codes” for more information. ■ Grounding requirements. See “Wiring Closet Recommendations” and “Distribution Rack Requirements” for details. 48 APPENDIX C: SITE REQUIREMENTS AND SAFETY CODES ■ Be sure that each wiring closet has a suitable ground. Ground all metal racks, enclosures, boxes, and raceways in the closet. ■ Use AC power, 15-ampere service receptacles, type N5/15 or NEMA 5-15R for 120 VAC, and the other system specifications shown in Appendix A. ■ Be especially sure to meet all system environmental requirements in Appendix A, such as ambient temperature and humidity. ■ Be sure that the ventilation in the wiring closet is adequate to maintain a temperature below 40 °C (104 °F). ■ Install a reliable air conditioning and ventilation system if you plan to have two or more CoreBuilder 9400 systems in a single wiring closet. ■ To prevent overheating during nonbusiness hours, guard against the ventilation being shut down while a CoreBuilder 9400 system remains powered up. Distribution Rack Requirements If you plan to mount your CoreBuilder 9400 system in a distribution rack, verify that your rack meets the basic mechanical and space requirements described in this section. Protective Grounding for the Rack Proper distribution rack grounding ensures that voltages induced into wiring by lightning or other disturbances are directed to ground. Normally, you use a distribution rack grounding kit and a ground conductor that is carried back to earth or to another suitable building ground. To order the grounding kit, contact your sales representative. Space Requirements for the Rack Provide enough space in front of and behind the system so that you can service it easily. Allow a minimum of 76 cm (30 in.) between the rack and any wall behind or in front of it. Extra room on each side is optional. See Figure 15. Install your distribution rack near an easily accessible power outlet. You can power down the system only by removing the power cord from the power source. Distribution Rack Requirements Figure 15 Recommended Service Access ■ 49 In countries other than the United States, comply with IEC Standard 297: Dimensions of Panels and Racks. In addition, 3Com recommends that your distribution racks meet these requirements: 76 cm (30 in.) ■ Use an open style, 19-inch rack. The rack styles shown in Figure 16 facilitate easy maintenance and provide excellent ventilation. ■ Use a rack that has the universal mounting rail hole pattern identified in IEC Standard 297. ■ Use a rack that is made of steel. ■ Install equipment in the lower half of the distribution rack to avoid making it top heavy. ■ Use a rack that supports approximately 272 kg (600 lb) ■ Use a rack that has adequate electrical grounding, for instance, with a distribution rack grounding kit. ■ Verify that the floor under the rack is level within 5 mm ( 3/16 in.). Use a floor-leveling cement compound or bolt the racks to the floor. ■ Attach the rack to the wiring closet floor with 9.5 mm ( 3/8 in.) lag screws or equivalent hardware. ■ Brace open distribution racks if the channel thickness is less than 6.4 mm ( 1/4 in.). 76 cm (30 in.) Mechanical Requirements for the Rack Verify that your racks comply with the standards and requirements in your cabling system plan and conform to these conventional standards: ■ In the United States, comply with EIA Standard RS-310C: Racks, Panels, and Associated Equipment. 50 APPENDIX C: SITE REQUIREMENTS AND SAFETY CODES Figure 16 Recommended Rack Styles Building and Electrical Codes Follow all appropriate building codes and authorities on electrical codes when planning your site and installing your cable for the CoreBuilder 9400 system.
