Index-1 iii 1 The HP Procurve Switch 6108 is a multiport switch that can be used to build high-performance switched workgroup networks. This switch is a store-andforward device that offers low latency for high-speed networking. HP Procurve Switch 6108 (HPJ4902A) Throughout this manual, this switch will be abbreviated as the Switch 6108. The Switch 6108 has six auto-sensing 10/100/1000Base-T RJ-45 ports and two dual-personality ports—either auto-sensing 10/100/1000Base-T RJ-45 or miniGBIC. This switch is designed to be used primarily to provide Gigabit/second network speed to the desktop. You can also directly connect servers and peripherals to this switch and connect the switch to a network backbone or to other switches, hubs, or routers. In addition, the Switch 6108 offers full network management capabilities. This chapter describes your HP Switch 6108 including: ■ ■ Front and back of the switch Switch features 1-1 Introducing the HP Procurve Switch 6108 Introducing the HP Procurve Switch 6108 Introducing the HP Procurve Switch 6108 Introducing the HP Procurve Switch 6108 Front of the Switch Front of the Switch Power and Fault LEDs Console port Reset and Clear buttons Self Test and Fan Status LEDs Mode LED View button and indicator LEDs Link and Mode LEDs for switch ports 10/100/1000Base-T RJ-45 ports* HP Procurve Switch 6108 Dual-personality ports (1000Base-T* or mini-GBIC) * All 10/100/1000Base-T RJ-45 ports have the IEEE 802.3ab “Auto MDI/MDIX” feature. Network Ports ■ Six auto-sensing 10/100/1000Base-T RJ-45 ports. All these ports have the IEEE 802.3ab “Auto MDI/MDI-X” feature, which means that you can use either straight-through or crossover twistedpair cables to connect any network devices to the switch. ■ Two dual-personality ports. You can use either the 10/100/1000Base-T RJ-45 connector, or install a supported HP Procurve mini-GBIC for fiberoptic connections. The RJ-45 connectors support the IEEE Auto MDI/MDI-X feature. Dual-Personality Port Operation. By default, the RJ-45 connnectors are enabled. If a mini-GBIC is installed in a slot, it is enabled and the associated RJ-45 connector is disabled and cannot be used. If the mini-GBIC is removed, the associated RJ-45 port is automatically re-enabled. 1-2 Introducing the HP Procurve Switch 6108 Front of the Switch Table 1-1. Switch LEDs Switch LEDs State Meaning Power (green) On Green The switch is receiving power. Off The switch is NOT receiving power. Fault (orange) Off The normal state; indicates that there are no fault conditions on the switch. On On briefly after the switch is powered on or reset, at the beginning of switch self test. If this LED is on for a prolonged time, the switch has encountered a fatal hardware failure, or has failed its self test. See chapter 4, “Troubleshooting” for more information. Self Test (green) Off The normal operational state; the switch is not undergoing self test. On The switch self test and initialization are in progress after you have power cycled or reset the switch. The switch is not operational until this LED goes off. The Self Test LED also comes on briefly when you “hot swap” a mini-GBIC into the switch; the mini-GBIC is self tested when it is hot swapped. Blinking* A component of the switch has failed its self test. The status LED for that component, for example an RJ-45 port, and the switch Fault LED will blink simultaneously. On Indicates the port is enabled and receiving a link indication from the connected device. Off One of these conditions exists: • no active network cable is connected to the port • the port is not receiving link beat or sufficient light • the port has been disabled through the switch console, the web browser interface, or HP TopTools. Blinking* If the LED is blinking simultaneously with the Fault LED, the corresponding port has failed its self test. Link (green – overlaid with the port number) Mode (Green) Displays network activity information, or whether the port is configured for full-duplex operation, or the speed of the connection depending on the mode selected. See “Mode LED View Button and Indicator LEDs” on the next page for more information. Mode LED View (3 green LEDs) Act Indicates that the port Mode LEDs are displaying network activity information. FDx Indicates that the port Mode LEDs are lit for ports that are in Full Duplex Mode. Spd Indicates that the port Mode LEDs are displaying the connection speed at which each port is operating: • if the port LED is off, the port is operating at 10 Mbps. • if the port LED is flashing**, the port is operating at 100 Mbps. • if the port LED is on continuously, the port is operating at 1000 Mbps. ** The flashing behavior is an on/off cycle once every 0.5 seconds, approximately. 1-3 Introducing the HP Procurve Switch 6108 LEDs Introducing the HP Procurve Switch 6108 Introducing the HP Procurve Switch 6108 Front of the Switch Switch LEDs State Meaning T/M (green – ports 7 and 8 only) On For the dual-personality ports, indicates the enabled port: • if the “T” is on, the 10/100/1000Base-T RJ-45 port is enabled. • if the “M” is on, the mini-GBIC port is enabled. Fan Status (green) On The cooling fan is operating normally. Blinking* The cooling fan has failed. The switch Fault LED will be blinking simultaneously. * The blinking behavior is an on/off cycle once every 1.6 seconds, approximately. 1-4 Introducing the HP Procurve Switch 6108 Front of the Switch To optimize the amount of information that can be displayed for each of the switch ports without overwhelming you with LEDs, the Switch 6108 uses a Mode LED for each port. The operation of this LED is controlled by the Mode LED View button, and the current setting is indicated by the Mode LED View indicator LEDs near the button. Press the button to step from one mode to the next. Mode LED View button and indicator LEDs Spd mode: off = 10 Mbps flash = 100 Mbps on = 1000 Mbps Mode LED (one per port) 1 Link 1 2 2 Act FDx Spd Mode LED View Mode ■ If the Activity (Act) indicator LED is lit, each Mode LED displays activity information for the associated port—it flickers as network traffic is received and transmitted through the port. ■ If the Full Duplex (FDx) indicator LED is lit, the Mode LEDs light for those ports that are operating in full duplex. ■ If the Speed (Spd) indicator LED is lit, the Mode LEDs behave as follows to indicate the connection speed for the port: • Off = 10 Mbps • Flashing = 100 Mbps (the flashing behavior is an on/off cycle once every 0.5 seconds, approximately) • On = 1000 Mbps 1-5 Introducing the HP Procurve Switch 6108 Mode LED View Button and Indicator LEDs Introducing the HP Procurve Switch 6108 Front of the Switch Introducing the HP Procurve Switch 6108 Console Port This port is used to connect a console to the Switch 6108 by using the serial cable supplied with the switch. This connection is described under “Connect a Console to the Switch” in chapter 2, “Installing the Switch”. The console can be a PC or workstation running a VT-100 terminal emulator, or a VT-100 terminal. Reset Button This button is used to reset the switch while it is powered on. This action clears any temporary error conditions that may have occurred and executes the switch self test. Clear Button This button is used for these purposes: ■ Deleting Passwords - When pressed by itself for at least one second, the button deletes any switch console access passwords that you may have configured. Use this feature if you have misplaced the password and need console access. This button is provided for your convenience, but its presence means that if you are concerned with the security of the switch configuration and operation, you should make sure the switch is installed in a secure location, such as a locked wiring closet. ■ 1-6 Restoring Factory Default Configuration - When pressed with the Reset button in a specific pattern, any configuration changes you may have made through the switch console, the web browser interface, and SNMP management are removed, and the factory default configuration is restored to the switch. For the specific method to restore the factory default configuration, see “Restoring the Factory Default Configuration” in chapter 4, “Troubleshooting” of this manual.

The rest of this chapter provides details on these steps. 1. Prepare the installation site (page 2-4). Make sure that the physical environment into which you will be installing the switch is properly prepared, including having the correct network cabling ready to connect to the switch and having an appropriate location for the switch. Please see page 2-3 for some installation precautions. 2. Install mini-GBICs (optional—page 2-5). The switch has two slots for installing mini-GBICs. Depending on where you will install the switch, it may be easier to install the mini-GBICs first. Note that the mini-GBICs can be hot swapped—they can be installed or removed while the switch is powered on. 3. Verify that the switch passes self test (page 2-7). This is a simple process of plugging the switch into a power source and observing that the LEDs on the switch’s front panel indicate correct switch operation. 4. Mount the switch (page 2-9). The Switch 6108 can be mounted in a 19-inch telco rack, in an equipment cabinet, on a wall, or on a horizontal surface. 5. Connect power to the switch (page 2-14). Once the switch is mounted, plug it in to the nearby main power source. 6. Connect the network devices (page 2-15). Using the appropriate network cables, connect the network devices to the switch ports. 7. Connect a console to the switch (page 2-16). You may wish to modify the switch’s configuration, for example, to configure an IP address so it can be managed using a web browser, from an SNMP network management station, or through a Telnet session. Configuration changes can be made easily by using the included console cable to connect a PC to the switch’s console port. At this point, your switch is fully installed. See the rest of this chapter if you need more detailed information on any of these installation steps. 2-2 Installing the Switch 6108 Installation Procedures Installation Precautions: Follow these precautions when installing your HP Switch 6108. Warning ■ The rack or cabinet should be adequately secured to prevent it from becoming unstable and/or falling over. Devices installed in a rack or cabinet should be mounted as low as possible, with the heaviest devices at the bottom and progressively lighter devices installed above. For safe operation, do not install the switch with the back face of the switch (with the fan vents) facing either downward or upward. ■ Make sure that the power source circuits are properly grounded, then use the power cord supplied with the switch to connect it to the power source. ■ If your installation requires a different power cord than the one supplied with the switch, be sure to use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your country. The mark is your assurance that the power cord can be used safely with the switch. ■ When installing the switch, note that the AC outlet should be near the switch and should be easily accessible in case the switch must be powered off. ■ Ensure that the switch does not overload the power circuits, wiring, and over-current protection. To determine the possibility of overloading the supply circuits, add together the ampere ratings of all devices installed on the same circuit as the switch and compare the total with the rating limit for the circuit. The maximum ampere ratings are usually printed on the devices near the AC power connectors. ■ Do not install the switch in an environment where the operating ambient temperature might exceed 55°C (131°F). ■ Make sure the air flow around the sides and back of the switch is not restricted. 2-3 Installing the Switch 6108 Cautions ■ Installing the Switch 6108 Installation Procedures 1. Prepare the Installation Site ■ Cabling Infrastructure - Ensure that the cabling infrastructure meets the necessary network specifications.

Installing or Removing mini-GBICs Notes ■ The mini-GBIC slots are shared with two of the 10/100/1000Base-T RJ-45 ports. If a mini-GBIC is installed in a slot, the associated RJ-45 port is disabled and cannot be used. ■ The mini-GBIC ports operate only at full duplex. Half duplex operation is not supported. ■ Make sure that the network cable is NOT connected when you install or remove a mini-GBIC. When this manual was printed, the supported mini-GBICs include the following: Caution ■ HP Procurve Gigabit-SX-LC mini-GBIC (J4858A) ■ HP Procurve Gigabit-LX-LC mini-GBIC (J4859A) ■ HP Procurve Gigabit-LH-LC mini-GBIC (J4860A) The HP Procurve mini-GBICs are Class 1 laser devices. Avoid direct eye exposure to the beam coming from the transmit port. 2-5 Installing the Switch 6108 You can install or remove a mini-GBIC from a mini-GBIC slot without having to power off the switch. Use only HP Procurve mini-GBICs. Installing the Switch 6108 Installation Procedures Installing the mini-GBICs: Hold the mini-GBIC by its sides and gently insert it into either of the slots on the switch until the mini-GBIC clicks into place.

Depending on when you purchased your HP Procurve mini-GBIC, it may have either of three different release mechanisms: a plastic tab on the bottom of the mini-GBIC, a plastic collar around the mini-GBIC, or a wire bail. To remove the mini-GBICs that have the plastic or plastic collar, push the tab or collar toward the switch until you see the mini-GBIC release from the switch (you can see it move outward slightly), and then pull it from the slot. To remove the mini-GBICs that have the wire bail, lower the bail until it is approximately horizontal, and then using the bail, pull the mini-GBIC from the slot. 2-6 Installing the Switch 6108 Installation Procedures 3. Verify the Switch Passes Self Test Before mounting the switch in its network location, you should first verify that it is working properly by plugging it into a power source and verifying that it passes its self test. 1. Connect the power cord supplied with the switch to the power connector on the back of the switch, and then into a properly grounded electrical outlet. Note The Switch 6108 does not have a power switch. It is powered on when the power cord is connected to the switch and to a power source. For safety, the power outlet should be located near the switch installation. The switch automatically adjusts to any voltage between 100-240 volts and either 50 or 60 Hz. There are no voltage range settings required. If your installation requires a different power cord than the one supplied with the switch, be sure to use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your country. The mark is your assurance that the power cord can be used safely with the switch. 2-7 Installing the Switch 6108 Connect power cord to the power connector Installing the Switch 6108 Installation Procedures 2. Check the LEDs on the switch as described below. Self Test LED Switch port LEDs Installing the Switch 6108 Power and Fault LEDs When the switch is powered on, it performs its diagnostic self test. Self test takes approximately 50 seconds to complete. LED Behavior: During the self test: • Initially, all the switch and port LEDs are on and stay on for most of the duration of the self test. • Most of the LEDs go off and then may come on again during phases of the self test. For the duration of the self test, the Self Test LED stays on. When the self test completes successfully: • The Power and Fan Status LEDs remain on. • The Fault and Self Test LEDs go off. • The port LEDs on the front of the switch go into their normal operational mode: – If the ports are connected to active network devices, the Link LEDs stay on and the Mode LEDs behave according to the mode selected. In the default mode (Activity), the Mode LEDs should flicker showing network activity on the port. – If the ports are not connected to active network devices, the Link and Mode LEDs will stay off. If the LED display is different than what is described above, especially if the Fault and Self Test LEDs stay on for more than 60 seconds or they start blinking, the self test has not completed correctly. Refer to chapter 4, “Troubleshooting” for diagnostic help. 2-8 Installing the Switch 6108 Installation Procedures 4. Mount the Switch After you have verified that the switch passes self test, you are ready to mount the switch in a stable location. The Switch 6108 can be mounted in these ways: ■ ■ ■ in a rack or cabinet on a horizontal surface on a wall Rack or Cabinet Mounting Warning For safe operation, please read the mounting precautions on page 2-3, before mounting a switch. Equipment Cabinet Note The 12-24 screws supplied with the switch are the correct threading for standard EIA/TIA open 19-inch racks. If you are installing the switch in an equipment cabinet such as a server cabinet, use the clips and screws that came with the cabinet in place of the 12-24 screws that are supplied with the switch. Complete step 1, on the next page. Then, plan which four holes you will be using in the cabinet and install all four clips and partially install the two bottom screws, as described in step 2 on the following page. Then proceed to step 3. 2-9 Installing the Switch 6108 The Switch 6108 is designed to be mounted in any EIA-standard 19-inch telco rack or communication equipment cabinet. Note that the mounting brackets have multiple mounting holes and can be rotated allowing for a wide variety of mounting options. Installing the Switch 6108 Installation Procedures Installing the Switch 6108 1. Use a #1 Phillips (cross-head) screwdriver and attach the mounting brackets to the switch with the included 8-mm M4 screws. 8 mm M4 screws Note Note that the mounting brackets have multiple mounting holes and can be rotated allowing for a wide variety of mounting options. These include mounting the switch so that its front face is flush with the face of the rack, or mounting it in a more balanced position as shown in the illustration. Note Steps 2, 3, and 4 on the next page describe a convenient method of mounting the switch in a rack by placing it on two screws that you first install in the rack. You may, instead, just hold the switch with attached brackets up to the rack and move it vertically until rack holes line up with the bracket holes and notches, then insert and tighten the four screws holding the brackets to the rack. 2-10 Installing the Switch 6108 Installation Procedures 2. Partially install a screw (5/8-inch number 12-24) into the top hole of a pair of holes that are 0.5 inches apart in each rack/cabinet upright as shown in the illustration below. Ensure that the screws are at the same level in each upright. Partially install a screw into the top hole of a close (0.5-inch) pair on both sides of the rack Place the switch in the rack and lower it so the notches in the bottom of the bracket slide onto the screws, then tighten these screws. Lower switch with mounting brackets onto the partially installed screw 2-11 Installing the Switch 6108 3. Installing the Switch 6108 Installation Procedures 4. Install the other number 12-24 screw through the hole in each bracket. Tighten these screws. Installing the Switch 6108 Install additional screw Wall Mounting You can mount the switch on a wall as shown in the illustrations on the next page. Warning For safe operation, do not install the switch with the back face of the switch (with the fan vents) facing either downward or upward. Caution The switch should be mounted only to a wall or wood surface that is at least 1/2-inch plywood or its equivalent. 2-12 1. Use a #1 Phillips (cross-head) screwdriver and attach the mounting brackets to the switch with the included 8-mm M4 screws. 2. Attach the switch to the wall or wood surface with two 5/8-inch number 12 wood screws (not included).

This improves the stability of the switch on the wall. 2-13 Installing the Switch 6108 Installation Procedures Horizontal Surface Mounting Place the switch on a table or other horizontal surface. The switch comes with rubber feet in the accessory kit that can be used to help keep the switch from sliding on the surface. Installing the Switch 6108 Attach the rubber feet to the four corners on the bottom of the switch within the embossed angled lines. Use a sturdy surface in an uncluttered area. You may want to secure the networking cables and switch power cord to the table leg or other part of the surface structure to help prevent tripping over the cords. Caution Make sure the air flow is not restricted around the sides and back of the switch. 5. Connect the Switch to a Power Source 2-14 1. Plug the included power cord into the switch’s power connector and into a nearby AC power source. 2. Re-check the LEDs during self test. See “LED Behavior” on page 2-8. Installing the Switch 6108 Installation Procedures 6. Connect the Network Cables Connect the network cables, described under “Cabling Infrastructure” (page 2-4), from the network devices or your patch panels to the fixed RJ-45 ports on the switch or to any mini-GBICs you have installed in the switch.

If a mini-GBIC is installed in a slot, the associated RJ-45 port is disabled. If you have any mini-GBICs installed in the switch, the type of network connections you will need to use depends on the type of mini-GBICs you have installed. See the table on page 2-4, and appendix B, “Switch Ports and Network Cables”, for the mini-GBIC cabling information. For mini-GBICs ports, and in general for all the switch ports, when a network cable from an active network device is connected to the port, the port LED for that port should go on. If the port LED does not go on when the network cable is connected to the port, see “Diagnosing With the LEDs” in chapter 4, “Troubleshooting”. 2-15 Installing the Switch 6108 To connect: Push the RJ-45 plug into the RJ-45 jack until the tab on the plug clicks into place. When power is on for the switch and for the connected device, the Link LED for the port should light to confirm a powered-on device (for example, an end node) is at the other end of the cable. Installing the Switch 6108 Installation Procedures 7. (Optional) Connect a Console to the Switch 6108 Installing the Switch 6108 The Switch 6108 has a full-featured, easy to use console interface for performing switch management tasks including the following: ■ Monitor switch and port status and observe network activity statistics ■ Modify the switch’s configuration to optimize switch performance, enhance network traffic control, and improve network security ■ Read the event log and access diagnostic tools to help in troubleshooting ■ Download new software to the switch ■ Add passwords to control access to the switch from the console, web browser interface, and network management stations The console can be accessed through these methods: ■ Out-of-band: The Switch 6108 come with a serial cable for connecting a PC or VT-100 terminal, to be used as a console, directly to the switch. ■ In-Band: Access the console using Telnet from a PC or UNIX station on the network, and a VT-100 terminal emulator. This method requires that you first configure the switch with an IP address and subnet mask by using either out-of-band console access or through DHCP/Bootp. For more information on IP addressing and on starting a Telnet session, see chapter 3, “Getting Started With Switch Configuration”, and the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. The Switch 6108 can simultaneously support one out-of-band console session through the Console Port and one in-band Telnet console session. Terminal Configuration To connect a console to the switch, configure the PC terminal emulator as a DEC VT-100 (ANSI) terminal or use a VT-100 terminal, and configure either one to operate with these settings: • any baud rate from 1200 to 115200 (the switch senses the speed) • 8 data bits, 1 stop bit, no parity, and flow control set to Xon/Xoff • For the Windows Terminal program, also disable (uncheck) the “Use Function, Arrow, and Ctrl Keys for Windows” option • For the Hilgraeve HyperTerminal program, select the “Terminal keys” option for the “Function, arrow, and ctrl keys act as” parameter. If you want to operate the console using a different configuration, make sure you change the settings on both the terminal and on the switch so they are compatible. Change the switch settings first, then change the terminal settings, then reboot the switch and reestablish the console session. 2-16 Installing the Switch 6108 Installation Procedures Direct Console Access To connect a console to the switch, follow these steps: hp procurve switch 6108 J4902A Power 1.

Notice that the end node devices are connected to the switch by “straight-through” or “crossover” twisted-pair cables. Either cable type can be used because of the IEEE 802.3ab “Auto-MDI/ MDIX” feature on the Switch 6108. 2-18 Installing the Switch 6108 Sample Network Topologies As a Segment Switch Server with “Gigabit” Ethernet NIC Category 5E twisted-pair “straight-through” or “crossover” cable for 1000 Mbps connection to server Gigabit fiber-optic cable to backbone Switch 6108 8M) (7M, 8) Mini-GBIC (7 and port 8T) or (7T, Gigabit 1000-TM) for each 10/100/ (T or Ports: connector Link 8T Gigabit only one 8 M !

That is, with its high performance, it can be used for interconnecting network segments—simply connect the network hubs that form those segments to the switch, or you can also connect other switches. In the illustration above, two “Fast” Ethernet hubs with PCs, printers, and local servers attached, are both connected to a Switch 6108. The devices attached to the two hubs can now communicate with each other through the switch. They can also all communicate with the server that is connected to the switch. Because the Switch 6108 has the IEEE 802.3ab “Auto-MDI/MDIX” feature, the connections between the switch and the hubs, and between the switch and end nodes or servers can be through category 5 “straight-through” or “crossover” twisted-pair cable. Category 3 or 4 cable can also be used if the connection is 10 Mbps only. In all cases, the device ports must be configured to auto negotiate the link characteristics for this feature to work. The switch, in turn, can be connected to a network backbone through fiberoptic cabling connected to a Gigabit-SX, -LX, or -LH mini-GBIC installed in the switch. Now, all the devices on these network segments can access other network resources that are connected elsewhere on the network backbone. 2-19 Installing the Switch 6108 “Fast” Ethernet Hubs Installing the Switch 6108 Sample Network Topologies Connecting to a Backbone Switch Switch 6108 8M) (7M, 8) Mini-GBIC (7 and port 8T) or (7T, Gigabit 000-T for each M) 10/100/1 (T or Ports: connector Link 8T Gigabit only one 8 M !

For example, you could use an HP Procurve Switch 8000M to interconnect each of your smaller switched workgroups to form a larger switched network. All the devices in this network can communicate with each other. With a Gigabit-SX Module, for example, in the Switch 8000M, the entire switched topology could be connected to a campus backbone, as shown in the illustration above. Note 2-20 In the illustration above, the 1000 Mbps fiber-optic connection between the Switch 6108 and the Switch 8000M is by way of a Gigabit-SX mini-GBIC installed in the Switch 6108 connected to a Gigabit-SX Module in the Switch 8000M. Installing the Switch 6108 Sample Network Topologies Stacking the Switch Switch 6108 units can be connected together, through standard network connections, and managed through a single IP address. Up to 16 switches can be connected together in such a “virtual stack”. You identify the switch as the “Commander” and give that switch an IP address. Up to 15 other switches in the network can then easily be configured as Members of the stack and managed through the Commander’s IP address. The management includes Telnet access and web browser interface access to the Commander and to each Member switch through the Commander. 2-21 Installing the Switch 6108 For more information on stacking your Switch 6108, please see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. 3 Getting Started With Switch Configuration This chapter is a guide for using the console Switch Setup screen to quickly assign an IP (Internet Protocol) address and subnet mask to the switch, set a Manager password, and, optionally, configure other basic features. For more information on using the switch console and the other switch management interfaces: the web browser interface and the SNMP management tool, HP TopTools for Hubs & Switches, please see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. Recommended Minimal Configuration Many other features can be configured through the switch’s console interface, to optimize the switch’s performance, to enhance your control of the network traffic, and to improve network security. Once an IP address has been configured on the switch, these features can be accessed more conveniently through a remote Telnet session, through the switch’s web browser interface, and from an SNMP network management station running a network management program, such as HP TopTools for Hubs & Switches. For a listing of switch features available with and without an IP address, refer to “How IP Addressing Affects Switch Operation” in the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. For more information on IP addressing, refer to “IP Configuration” in the Management and Configuration Guide. 3-1 Getting Started With Switch Configuration In the factory default configuration, the switch has no IP (Internet Protocol) address and subnet mask, and no passwords. In this state, it can be managed only through a direct console connection. To manage the switch through inband (networked) access, you should configure the switch with an IP address and subnet mask compatible with your network. Also, you should configure a Manager password to control access privileges from the console and web browser interface. Other parameters in the Switch Setup screen can be left at their default settings or you can configure them with values you enter. Getting Started With Switch Configuration Note By default, the switch is configured to acquire an IP address configuration from a DHCP or Bootp server. To use DHCP/Bootp instead of the manual method described in this chapter, see “DHCP/Bootp Operation” in the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. Using the Console Setup Screen The quickest and easiest way to minimally configure the switch for management and password protection in your network is to use a direct console connection to the switch, start a console session, and access the Switch Setup screen. 1. Using the method described in the preceding section, connect a terminal device to the switch and display the switch console command (CLI) prompt (the default display). The CLI prompt appears displaying the switch model number: HP Procurve Switch 6108# At the prompt, enter the setup command to display the Switch Setup screen. The following illustration shows the Setup screen with the default settings. 3. Use the [Tab] key to select the Manager Password field and enter a manager password of up to 16 characters. Getting Started With Switch Configuration 2. 3-2 Getting Started With Switch Configuration 4. [Tab] to the IP Config (DHCP/Bootp) field and use the Space bar to select the Manual option. 5. [Tab] to the IP Address field and enter the IP address that is compatible with your network. 6. [Tab] to the Subnet Mask field and enter the subnet mask used for your network. Press [Enter], then [S] (for Save). 7. Here is some information on the fields in the Setup screen. For more information on these fields, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch: Default System Name blank Optional; up to 25 characters, including spaces System Contact blank Optional; up to 48 characters, including spaces Manager Password blank Recommended; up to 16 characters (no blank spaces) Logon Default CLI The default setting selects the command line interface for console access. The alternative is the menu interface. Time Zone 0 (none) Optional; 1440 to -1440. The number of minutes your location is to the West (-) or East (+) of GMT. Community Name public Default setting recommended. Spanning Tree Enabled No Default setting recommended unless STP is already running on your network or the switch will be used in complex network topologies. Default Gateway blank Optional; Enter the IP address of the next-hop gateway node if network traffic needs to be able to reach off-subnet destinations. Time Sync Method None Optional; The protocol the switch uses to acquire a time signal. The options are SNTP and TimeP. TimeP Mode Disabled Optional; The method the switch uses to acquire the TimeP server address. IP Config (DHCP/Bootp) DHCP/Bootp Set to Manual unless a DHCP/Bootp server is used on your network to configure IP addressing. IP Address xxx.xxx.xxx.xxx Recommended; If you set IP Config to Manual, then enter an IP address compatible with your network. Note: The IP address and subnet mask assigned for the switch must be compatible with the IP addressing used in your network. For more information on IP addressing, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. Subnet Mask xxx.xxx.xxx.xxx Recommended; If you entered an IP address, then enter a subnet mask compatible with your network. 3-3 Getting Started With Switch Configuration Parameter Getting Started With Switch Configuration Where to Go From Here The above procedure configures your switch with a Manager password, IP address, and subnet mask. As a result, with the proper network connections, you can now manage the switch from a PC equipped with Telnet, a web browser interface, or from an SNMP-based network management station using a tool such as HP TopTools for Hubs & Switches. Some basic information on managing your switch is included in the next section. For more information on the console, web browser, and SNMP management interfaces and all the features that can be configured on the Switch 6108, please see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. Getting Started With Switch Configuration To Recover from a Lost Manager Password: If you cannot start a console session at the manager level because of a lost Manager password, you can clear all passwords and user names by getting physical access to the switch and pressing and holding the Clear button for a full second. 3-4 Getting Started With Switch Configuration Using the IP Address for Remote Switch Management Using the IP Address for Remote Switch Management With your Switch 6108, you can use the switch’s IP address to manage the switch from any PC that is on the same subnet as the switch. You can use either a Telnet session or a standard web browser to manage the switch. Starting a Telnet Session To access the switch through a Telnet session, follow these steps: 1. Make sure the switch is configured with an IP address and that the switch is reachable from the PC that is running the Telnet session (for example, by using a Ping command to the switch’s IP address). 2. Start the Telnet program on a PC that is on the same subnet as the switch and connect to the switch’s IP address. 3. You will see the copyright page and the message “Press any key to continue”. Press a key, and you will then see the switch console command (CLI) prompt, for example: Enter help or ? to see a list of commands that can be executed at the prompt. Entering any command followed by help provides more detailed context help information about the command. Entering any command followed by ? displays a list of options that are available at that point in the command entry. Starting a Web Browser Session Your Switch 6108 can be managed through a graphical interface that you can access from any PC or workstation on the network by running your web browser and typing in the switch’s IP address as the URL. No additional software installation is required to make this interface available; it is included in the switch’s onboard software. A typical web browser interface screen is shown in the next illustration. 3-5 Getting Started With Switch Configuration HP Procurve Switch 6108# Getting Started With Switch Configuration Using the IP Address for Remote Switch Management Getting Started With Switch Configuration For more information on using the web browser interface, please see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. An extensive help system is also available for the web browser interface. To access the help system though, the subnet on which the switch is installed must have access to the internet, or HP TopTools for Hubs & Switches needs to be installed on a network management station that is on the subnet. 3-6 4 Troubleshooting This chapter describes how to troubleshoot your HP Procurve Switch 6108. Note that this document describes troubleshooting mostly from a hardware perspective. You can perform more in-depth troubleshooting on the Switch 6108 using the software tools available with the switch, including the full-featured console interface, the built-in web browser interface, and HP TopTools for Hubs & Switches, the SNMP-based network management tool. For more information, see the chapter “Troubleshooting” in the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. This chapter describes the following: ■ basic troubleshooting tips (page 4-1) ■ diagnosing with the LEDs (page 4-4) ■ Proactive Networking tools (page 4-8) ■ hardware diagnostic tests (page 4-9) ■ restoring the factory default configuration (page 4-11) ■ downloading new software to the Switch 6108 (page 4-12) ■ HP Customer Support Services (page 4-12) Basic Troubleshooting Tips Most problems are caused by the following situations. Check for these items first when starting your troubleshooting: ■ • If the connected device is also configured to Auto, the switch will automatically negotiate both link speed and communication mode. 4-1 Troubleshooting Connecting to devices that have a fixed full-duplex configuration. The RJ-45 ports are configured as “Auto”. That is, when connecting to attached devices, the switch will operate in one of two ways to determine the link speed and the communication mode (half duplex or full duplex): Troubleshooting Basic Troubleshooting Tips • If the connected device has a fixed configuration, for example 100 Mbps, at half or full duplex, the switch will automatically sense the link speed, but will default to a communication mode of half duplex. Because the Switch 6108 behaves in this way (in compliance with the IEEE 802.3 standard), if a device connected to the switch has a fixed configuration at full duplex, the device will not connect correctly to the switch. The result will be high error rates and very inefficient communications between the switch and the device. Make sure that all devices connected to the Switch 6108 are configured to auto negotiate, or are configured to connect at half duplex (all hubs are configured this way, for example). ■ Faulty or loose cables. Look for loose or obviously faulty connections. If they appear to be OK, make sure the connections are snug. If that does not correct the problem, try a different cable. ■ Non-standard cables. Non-standard and miswired cables may cause network collisions and other network problems, and can seriously impair network performance. Use a new correctly-wired cable or compare your cable to the cable in appendix B, “Cables and Connectors” for pinouts and correct cable wiring. A category 5 cable tester is a recommended tool for every 100Base-TX and 1000Base-T network installation. ■ Improper Network Topologies. It is important to make sure you have a valid network topology. Common topology faults include excessive cable length and excessive repeater delays between end nodes. If you have network problems after recent changes to the network, change back to the previous topology. If you no longer experience the problems, the new topology is probably at fault. Sample topologies are shown at the end of chapter 2 in this book, and some topology configuration guidelines can be found online at the HP Procurve web site, http://www.hp.com/go/ hpprocurve. Troubleshooting In addition, you should make sure that your network topology contains no data path loops. Between any two end nodes, there should be only one active cabling path at any time. Data path loops will cause broadcast storms that will severely impact your network performance. For your Switch 6108, if you wish to build redundant paths between important nodes in your network to provide some fault tolerance, you should enable Spanning Tree Protocol support on the switch. This ensures that only one of the redundant paths is active at any time, thus avoiding data path loops. Spanning Tree can be enabled through the switch console, the web browser interface, or HP TopTools for Hubs & Switches. 4-2 Troubleshooting Basic Troubleshooting Tips The Switch 6108 also supports Trunking, which allows multiple network cables to be used for a single network connection without causing a data path loop. For more information on Spanning Tree and Trunking, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. ■ Check the port configuration. A port on your Switch 6108 may not be operating as you expect because it has been put into a “blocking” state by Spanning Tree, GVRP (automatic VLANs), or LACP (automatic trunking). (Note that the normal operation of the Spanning Tree, GVRP, and LACP features may put the port in a blocking state.) Or, the port just may have been configured as disabled through software. Use the switch console to determine the port’s configuration and verify that there is not an improper or undesired configuration of any of the switch features that may be affecting the port. For more information, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. For more information on possible network problems and their solutions, refer to the technical note “Troubleshooting LAN Performance and Intermittent Connectivity Problems”, which can be found on the HP Procurve web site, http://www.hp.com/go/hpprocurve, in the Information Library section. Troubleshooting 4-3 Troubleshooting Diagnosing with the LEDs Diagnosing with the LEDs Table 3-1 shows LED patterns on the switch and the switch modules that indicate problem conditions. 1. Check in the table for the LED pattern that you see on your switch. 2. Refer to the corresponding diagnostic tip on the next few pages. Table 4-1. LED Error Indicators LED Pattern Indicating Problems Power Fault Self Test Fan Status (in Link view mode) Diagnostic Tips Off with power cord plugged in * * * * ➊ * * ➋ * * ➌ * ➍ On Prolonged On Prolonged On On Blinking† On Blinking † On Blinking† Port LED † Off Blinking Blinking† Blinking† * Blinking† ➎ On Off Off * Off with cable connected ➏ On Off Off * On, but the port is not communicating ➐ Troubleshooting * This LED is not important for the diagnosis. † The blinking behavior is an on/off cycle once every 1.6 seconds, approximately. 4-4 Troubleshooting Diagnosing with the LEDs Diagnostic Tips: Problem Solution ➊ The switch is not plugged into an active AC power source, or the switch’s power supply may have failed. 1. Verify that the power cord is plugged into an active power source and to the switch. Make sure these connections are snug. 2. Try power cycling the switch by unplugging and plugging the power cord back in. 3. If the Power LED is still not on, verify that the AC power source works by plugging another device into the outlet. Or try plugging the switch into a different outlet or try a different power cord. If the power source and power cord are OK and this condition persists, the switch power supply may have failed. Call your HP-authorized LAN dealer, or use the electronic support services from HP to get assistance. See the Customer Support/Warranty booklet for more information. ➋ A switch hardware failure has occurred. All the LEDs will stay on indefinitely. Try power cycling the switch. If the fault indication reoccurs, the switch may have failed. Call your HP-authorized LAN dealer, or use the electronic support services from HP to get assistance. See the Customer Support/Warranty booklet for more information. ➌ The switch has experienced a software failure during self test. 1. Try resetting the switch by pressing the Reset button on the front of the switch, or by power cycling the switch. 2. If the fault indication reoccurs, attach a console to the switch (as indicated in chapter 2) and configure it to operate at 9600 baud. Then, reset the switch. Messages should appear on the console screen and in the console log identifying the error condition. You can view the console log at that point by selecting it from the console Main Menu. If necessary to resolve the problem, contact your HP-authorized LAN dealer, or use the electronic support services from HP to get assistance. See the Customer Support/ Warranty booklet for more information. ➍ One or both of the switch cooling fans may have failed. Try disconnecting power from the switch and wait a few moments. Then reconnect the power to the switch and check the LEDs again. If the error indication reoccurs, one or both of the fans has failed. The switch has two fans and may continue to operate under this condition if the ambient temperature does not exceed normal room temperature, but for best operation, the switch should be replaced. Contact your HP-authorized LAN dealer, or use the electronic support services from HP to get assistance. See the Customer Support/Warranty booklet for more information. ➎ The network port for which the LED is blinking has experienced a self test or initialization failure. Try power cycling the switch. If the fault indication reoccurs, the switch port may have failed. Call your HP-authorized LAN dealer, or use the electronic support services from HP to get assistance. See the Customer Support/Warranty booklet for more information. If the port is a mini-GBIC, verify that it is one of the mini-GBICs supported by the switch. Unsupported mini-GBICs will be identified with this fault condition. The supported miniGBICs are listed in Chapter 2, “Installing the Switch 6108” on page 2-5. The mini-GBICs are also tested when they are “hot-swapped”—installed or changed while the switch is powered on. To verify that the port has failed, try removing and reinstalling the mini-GBIC without having to power off the switch. If the port fault indication reoccurs, you will have to replace the mini-GBIC. 4-5 Troubleshooting Tip Troubleshooting Diagnosing with the LEDs Tip Problem Solution ➏ The network connection is not working properly. Try the following procedures: • For the indicated port, verify that both ends of the cabling, at the switch and the connected device, are connected properly. • Verify the connected device and switch are both powered on and operating correctly. • Verify that you have used the correct cable type for the connection: – For twisted-pair connections to the 10/100/1000-T ports, if the port is configured to “Auto” (auto negotiate), either “straight-through” or “crossover” cables can be used because of the IEEE 802.3ab “Auto MDI/MDI-X” feature of these ports. Note: If the switch port configuration is changed to one of the fixed configuration options (for example, 100 Mbps/Full Duplex), then the port operates as MDI-X only and you must use the correct type of cable for the connection. In general, for connecting an end node (MDI port) to the switch, use “straight-through” cable; for connecting to MDI-X ports on hubs, other switches, and routers, use “crossover” cable. • • • • Troubleshooting • 4-6 – For fiber-optic connections, verify that the transmit port on the switch is connected to the receive port on the connected device, and the switch receive port is connected to the transmit port on the connected device. For the dual-personality 10/100/1000-T ports, be sure a mini-GBIC is not installed in the associated slot. For 1000Base-T connections, verify that the network cabling complies with the IEEE 802.3ab standard. the cable should be installed according to the ANSI/TIA/EIA-568A-5 specifications. Cable testing should comply with the stated limitations for Attenuation, Near-End Crosstalk, Far-End Crosstalk, Equal-Level Far-End Crosstalk (ELFEXT), Multiple Disturber ELFEXT, and Return Loss. The cable verification process must include all patch cables from any end devices, including the switch, to any patch panels in the cabling path. Verify that the port has not been disabled through a switch configuration change. You can use the console interface, or, if you have configured an IP address on the switch, use the web browser interface, or HP TopTools for Hubs & Switches network management software to determine the state of the port and re-enable the port if necessary. Verify that the switch port configuration matches the configuration of the attached device. For example, if the switch port is configured as “Auto”, the port on the attached device also MUST be configured as “Auto”. Depending on the port type, twisted-pair or fiber-optic, if the configurations don’t match, the results could be a very unreliable connection, or no link at all. If the other procedures don’t resolve the problem, try using a different port or a different cable. Troubleshooting Diagnosing with the LEDs Tip Problem Solution ➐ The port may be improperly configured, or the port may be in a “blocking” state by the normal operation of the Spanning Tree, LACP, or IGMP features. Use the switch console to see if the port is part of a dynamic trunk (through the LACP feature) or to see if Spanning Tree is enabled on the switch, and to see if the port may have been put into a “blocking” state by those features. The show lacp command displays the port status for the LACP feature; the show spanning-tree command displays the port status for Spanning Tree. Also check the Port Status screen using the show interfaces command to see if the port has been configured as “disabled”. Other switch features that may affect the port operation include VLANs and IGMP. Use the switch console to see how the port is configured for these features. For software troubleshooting tips, see the chapter “Troubleshooting” in the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. Make sure also, that the device at the other end of the connection is indicating a good link to the switch. If it is not, the problem may be with the cabling between the devices or the connectors on the cable. Troubleshooting 4-7 Troubleshooting Proactive Networking Proactive Networking The HP Procurve Switch 6108 has built-in management capabilities that proactively help you manage your network including: ■ finding and helping you fix the most common network error conditions (for example, faulty network cabling, and non-standard network topologies) ■ informing you of the problem with clear, easy-to-understand messages ■ recommending network configuration changes to enhance the performance of your network The following interfaces provide tests, indicators, and an event log that can be used to monitor the switch and its network connections and to help you take advantage of these proactive networking features: ■ HP TopTools for Hubs & Switches — an SNMP-based network management tool that is included with your switch. ■ A graphical web browser interface that you can use to manage your switch from a PC running a supported web browser, for example Microsoft Internet Explorer, and Netscape Communicator. ■ A full-featured easy-to-use console interface that you can access by connecting a standard terminal or PC running a terminal emulator to the switch’s console port. The cable to make that connection is provided with your switch. The console interface is also accessible through a Telnet connection. Troubleshooting For more information on using these software tools to diagnose and manage your switch, see the “Troubleshooting” chapter in the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. 4-8 Troubleshooting Hardware Diagnostic Tests Hardware Diagnostic Tests Testing the Switch by Resetting It If you believe that the switch is not operating correctly, you can reset the switch to test its circuitry and operating code. To reset a switch, either: ■ Unplug and plug in the power cord (power cycling) ■ Press the Reset button on the front of the switch Power cycling the switch and pressing the Reset button both cause the switch to perform its power-on self test, which almost always will resolve any temporary operational problems. These reset processes also cause any network traffic counters to be reset to zero, and cause the System Up Time timer to reset to zero. Checking the Switch LEDs The self test passes if the Fault and Self Test LEDs on the front of the switch go off after approximately 50 seconds. If these LEDs stay on longer than 60 seconds or begin blinking, there may be a problem with the switch. See “Diagnosing With the LEDs” on page 4-4 for information on interpreting the LED patterns. Checking Console Messages 4-9 Troubleshooting Useful diagnostic messages may be displayed on the console screen when the switch is reset. As described in chapter 2 under step 7, “Connect a Console to the Switch”, connect a PC running a VT-100 terminal emulator program or a standard VT-100 terminal to the switch’s Console Port and configure it to run at 9600 baud, and with the other terminal communication settings shown on page 2-16. Then, when you reset the switch, note the messages that are displayed. Additionally, you can check the switch event log, which can be accessed from the console using the show log command, or from the console Main Menu. Troubleshooting Hardware Diagnostic Tests Testing Twisted-Pair Cabling Network cables that fail to provide a link or provide an unreliable link between the switch and the connected network device may not be compatible with the IEEE 802.3 Type 10Base-T, 100Base-TX, or 1000Base-T standards. The twisted-pair cables attached to the Switch 6108 must be compatible with the appropriate standards. To verify that your cable is compatible with these standards, use a qualified cable test device. Testing Switch-to-Device Network Communications You can perform the following communication tests to verify that the network is operating correctly between the switch and any connected device that can respond correctly to the communication test. ■ Link Test -- a physical layer test that sends IEEE 802.2 test packets to any device identified by its MAC address ■ Ping Test -- a network layer test used on IP networks that sends test packets to any device identified by its IP address These tests can be performed through the switch console interface from a terminal connected to the switch or through a Telnet connection, or from the switch’s web browser interface. For more information, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. These tests can also be performed from an SNMP network management station running a program that can manage the switch, for example, HP TopTools for Hubs & Switches. Testing End-to-End Network Communications Troubleshooting Both the switch and the cabling can be tested by running an end-to-end communications test -- a test that sends known data from one network device to another through the switch. For example, if you have two PCs on the network that have LAN adapters between which you can run a link-level test or Ping test through the switch, you can use this test to verify that the entire communication path between the two PCs is functioning correctly. See your LAN adapter documentation for more information on running a link test or Ping test. 4-10 Troubleshooting Restoring the Factory Default Configuration Restoring the Factory Default Configuration As part of your troubleshooting process on the Switch 6108, it may become necessary to return the switch configuration to the factory default settings. This process momentarily interrupts the switch operation, clears any passwords, clears the console event log, resets the network counters to zero, performs a complete self test, and reboots the switch into its factory default configuration including deleting the IP address, if one is configured. Note This process removes all switch configuration changes that you have made from the factory default settings. This includes, for example, configuration of VLANs, Spanning Tree, trunks, and stacking. Returning the configuration of these features to their factory default settings (usually disabling them) may result in network connectivity issues. If the switch has a valid configuration, and you are restoring the factory default settings for a reason other than configuration problems, you should save the switch configuration prior to performing the factory default reset. Then, after the reset and resolution of the original problem, you can restore the saved configuration to the switch. For both the save and restore processes, you can use the console copy command. For more information on this command, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your switch. You can restore the factory default configuration either on the switch itself, or through the switch console. To execute the factory default reset on the switch, perform these steps: Using pointed objects, simultaneously press both the Reset and Clear buttons on the front of the switch. 2. Continue to press the Clear button while releasing the Reset button. 3. When the Self Test LED begins to blink, release the Clear button. The switch will then complete its self test and begin operating with its configuration restored to the factory default settings. To restore the factory default configuration using the console, execute the erase startup-config command from the console command prompt. 4-11 Troubleshooting 1.

A-2 B Switch Ports and Network Cables This appendix includes switch connector information and network cable information for cables that should be used with the Switch 6108, including minimum pin-out information and specifications for twisted-pair cables. Note Switch Ports The RJ-45 10/100/1000Base-T ports on the switch accept 100-ohm unshielded and shielded twisted-pair cable with RJ-45 connectors as described on the next page. Twisted-Pair Cables 10 Mbps Operation Category 3, 4, or 5 100-ohm unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable, complying with IEEE 802.3 Type 10Base-T specifications, fitted with RJ-45 connectors 100 Mbps Operation Category 5 100-ohm UTP or STP cable, complying with IEEE 802.3u 100Base-TX specifications, fitted with RJ-45 connectors 1000 Mbps Operation Category 5 100-ohm 4-pair UTP or STP cable, complying with IEEE 802.3ab 1000Base-T specifications, fitted with RJ-45 connectors—Category 5E or better is recommended (please see “Note on 1000Base-T Cable Requirements”, below) Note on 1000Base-T Cable Requirements. The Category 5 networking cables that work for 100Base-TX connections should also work for 1000Base-T, as long as all four-pairs are connected. But, for the most robust connections you should use cabling that complies with the Category 5E specifications, as described in Addendum 5 to the TIA-568-A standard (ANSI/ TIA/EIA-568-A-5). B-1 Switch Ports and Network Cables Incorrectly wired cabling is the most common cause of problems for LAN communications. HP recommends that you work with a qualified LAN cable installer for assistance with your cabling requirements. Switch Ports and Network Cables Because of the increased speed provided by 1000Base-T (Gigabit-T), network cable quality is more important than for either 10Base-T or 100Base-TX. Site Cabling plants being used to carry 1000Base-T networking must comply with the IEEE 802.3ab standards. In particular, the cabling must pass tests for Attenuation, Near-End Crosstalk (NEXT), and Far-End Crosstalk (FEXT). Additionally, unlike the cables for 100Base-TX, the 1000Base-T cables must pass tests for Equal-Level Far-End Crosstalk (ELFEXT) and Return Loss. Switch Ports and Network Cables When testing your cabling, be sure to include the patch cables that connect the switch and other end devices to the patch panels on your site. The patch cables are frequently overlooked when testing cable and they must also comply with the cabling standards. Fiber-Optic B-2 1000Base-SX 62.5/125 µm or 50/125 µm (core/cladding) diameter, gradedindex, multimode fiber-optic cables, complying with the ITU-T G.651 and ISO/IEC 793-2 Type A1b or A1a respectively, fitted with LC connectors. 1000Base-LX single mode fiber-optic cables, complying with the ITU-T G.652 and ISO/IEC 793-2 Type B1 standards, fitted with LC connectors OR 62.5/125 µm or 50/125 µm (core/cladding) diameter, gradedindex, multimode fiber-optic cables, complying with the ITU-T G.651 and ISO/IEC 793-2 Type A1b or A1a respectively, fitted with LC connectors Note: Multimode fiber-optic cabling may be used for a 1000Base-LX application, but a mode conditioning patch cord may be needed. See “Mode Conditioning Patch Cord for Gigabit-LX” on page B-3 for more information. 1000Base-LH single mode fiber-optic cables, complying with the ITU-T G.652 and ISO/IEC 793-2 Type B1 standards, fitted with LC connectors Switch Ports and Network Cables Mode Conditioning Patch Cord for Gigabit-LX Mode Conditioning Patch Cord for Gigabit-LX The following information applies to installations in which multimode fiber-optic cables are connected to a Gigabit-LX port. Gigabit-LX mini-GBICs, since they are designed to operate with both singlemode and multimode cable, do not provide the transmission conditioning internally. Thus, under certain circumstances, depending on the cable used and the lengths of the cable runs, an external Mode Conditioning Patch Cord may need to be installed between the Gigabit-LX transmitting device and the multimode network cable to provide the transmission conditioning. If you experience a high number of transmission errors on the Gigabit-LX ports, usually CRC or FCS errors, you may need to install one of these patch cords between the Gigabit-LX port in your switch and your multimode fiberoptic network cabling, and between the Gigabit-LX transmission device and the network cabling at the other end of the multimode fiber-optic cable run. A patch cord must be installed at both ends. The patch cord consists of a short length of single-mode fiber cable coupled to graded-index multimode fiber cable on the transmit side, and only multimode cable on the receive side. The section of single-mode fiber is connected in such a way that it minimizes the effects of the differential mode delay in the multimode cable. Note Most of the time, if you are using good quality graded-index multimode fiber cable that adheres to the standards listed on page 2-4, there should not be a need to use mode conditioning patch cords in your network. This is especially true if the fiber runs in your network are relatively short. If you are using single-mode fiber-optic cabling in your network, there is no need to use mode conditioning patch cords. Connect the single-mode network cable directly to the Gigabit-LX mini-GBIC. B-3 Switch Ports and Network Cables Unlike Gigabit-SX, which connects to only multimode fiber-optic cabling, Gigabit-LX can use either single-mode or multimode cable. Multimode cable has a design characteristic called “Differential Mode Delay”, which requires that the transmission signals be “conditioned” to compensate for the cable design and thus prevent resulting transmission errors. Since Gigabit-SX is designed to operate only with multimode cable, Gigabit-SX mini-GBICs can provide that transmission conditioning internally. Switch Ports and Network Cables Mode Conditioning Patch Cord for Gigabit-LX Installing the Patch Cord As shown in the illustration below, connect the patch cord to the Gigabit-LX mini-GBIC with the section of single-mode fiber plugged in to the Tx (transmit) port. Then, connect the other end of the patch cord to your network cabling patch panel, or directly to the network multimode fiber. Tx Rx If you connect the patch cord directly to the network cabling, you may need to install a female-to-female adapter to allow the cables to be connected together. Switch Ports and Network Cables Gigabit-LX port To network multimode cabling The multimode cable in the patch cord must match the characteristics of your network cable Mode Conditioning Patch Cord Single-mode section plugs into Tx port on Gigabit-LX Transceiver or Gigabit-LX mini-GBIC Make sure you purchase a patch cord that has LC connectors on the end that connects to the Gigabit-LX mini-GBIC, and has multimode fibers that match the characteristics of the multimode fiber in your network. Recommended Patch Cords Hewlett-Packard maintains a list of recommended Mode Conditioning Patch Cords that have been tested and verified to operate correctly with the HP Procurve Gigabit-LX Transceiver and HP Procurve Gigabit-LX LC mini-GBIC. The list is on the HP Procurve web site, http://www.hp.com/go/hpprocurve, in the Technical Support section. B-4 Switch Ports and Network Cables Twisted-Pair Cable/Connector Pin-Outs Twisted-Pair Cable/Connector Pin-Outs So, for any connection, a “straight-through” twisted-pair cable can be used — you no longer have to use “crossover” cables. If you do happen to use a correctly wired crossover cable, though, the switch will still be able to automatically detect the MDI/MDI-X operation of the connected device and will link correctly. Note Using Fixed Configurations. If the port configuration is changed to any of the fixed configurations though, for example 100 Mbps/full duplex, the port operates as MDI-X only and the correct cable type must be used: for connections to MDI ports, such as end nodes, use a “straight-through” cable; for connections to MDI-X ports, such as on hubs and other switches, use a “crossover” cable. Other Wiring Rules: ■ All twisted-pair wires used for 10 Mbps, and 100 Mbps operation must be twisted through the entire length of the cable. The wiring sequence must conform to EIA/TIA 568-B (not USOC). See “Twisted-Pair Cable Pin Assignments” later in this appendix for a listing of the signals used on each pin. ■ For 1000Base-T connections, all four pairs of wires in the cable must be available for data transmission. Please see “Note on 1000Base-T Cable Requirements” on page B-1 for more information on 1000Base-T cabling. ■ For 10 Mbps connections to the ports, you can use Category 3, 4, or 5 unshielded twisted-pair cable, as supported by the IEEE 802.3 Type 10Base-T standard. B-5 Switch Ports and Network Cables The IEEE 802.3ab “Auto MDI/MDI-X” Feature: The 10/100/1000Base-T ports on the Switch 6108 all have the “Auto MDI/MDI-X” feature that is part of the IEEE 802.3ab standard. They automatically detect the type of port on any device connected to the Switch 6108 and then operate as either an MDI or MDI-X port, whichever is appropriate. If you connect a Switch 6108 twistedpair port to another switch or hub, which typically have MDI-X ports, the Switch 6108 ports operates as an MDI port and connects correctly. If you connect an end node, such as a server or PC which typically have MDI ports, to the Switch 6108, the switch port operates as an MDI-X port and connects correctly. Switch Ports and Network Cables Switch Ports and Network Cables Twisted-Pair Cable/Connector Pin-Outs B-6 ■ For 100 Mbps connections to the ports, use 100-ohm Category 5 UTP or STP cable only, as supported by the IEEE 802.3u Type 100Base-TX standard. ■ For 1000 Mbps connections, 100-ohm Category 5E or better cabling is recommended. Switch Ports and Network Cables Twisted-Pair Cable/Connector Pin-Outs Straight-Through Twisted-Pair Cable for 10 Mbps or 100 Mbps Network Connections Because of the Auto MDI/MDI-X operation of the ports on the switch, for all network connections, to PCs, servers or other end nodes, or to hubs or other switches, you can use “straight-through” cables. For this feature to operate correctly, the port on the connected device must also be configured as Auto, not in any fixed configuration such as 100 Mbps/ full duplex. Cable Diagram Switch Ports and Network Cables Note Pins 1 and 2 on connector “A” must be wired as a twisted pair to pins 1 and 2 on connector “B”. Pins 3 and 6 on connector “A” must be wired as a twisted pair to pins 3 and 6 on connector “B”. Pins 4, 5, 7, and 8 are not used in this application, although they may be wired in the cable.
