These 24-port and 48-port switches do not have a power switch; they are powered on when connected to an active AC power source. The switches automatically adjust to any voltage between 100-127 and 200-240 volts and either 50 or 60 Hz. There are no voltage range settings required.

Introducing the Switch

Switch Features

The following are the features of the Switches:

■ 24 or 48 auto-sensing 10/100/1000BASE-T RJ-45 ports with Auto-MDIX.

■ Two SFP+ uplink slots supporting HP SFP and SFP+ transceivers.

■ PoE+ operation—the switches are IEEE 802.3 at compliant and provide

up to 30W per port to power IP phones, wireless access points, Web cameras, and more. For more information, see the HP Power over Ethernet (PoE/PoE+) Planning and Implementation Guide, which is on the HP Web site at www.hp.com/networking/support.

■ The switches support some pre-standard PoE devices. However, the use

of a cross-over cable may be required.

■ Plug-and-play networking—all ports are enabled—just connect the

network cables to active network devices and your switched network is operational.

■ Auto-MDIX on all twisted-pair ports, meaning that all twisted-pair

connections can be made using straight-through cables. Cross-over cables are not required, although they will also work.

■ Automatic learning of the hardware addresses in each switch’s 16000-

address forwarding table, (with configurable address aging value).

■ Automatically negotiated full-duplex operation for the 10/100/1000 RJ-45

ports when connected to other auto-negotiating devices.

■ A “Save Power” mode option that keeps port LEDs turned off except for

when the LED Mode select button is pressed.

■ An automatic low-power mode for ports when a link is not present.

■ Easy management of the switches through several available interfaces:

• Console interface — a full featured, easy to use, VT-100 terminal interface that is especially good for out-of-band switch management or for Telnet access to the switch.

• Web browser interface — an easy to use built-in graphical interface that can be accessed from common Web browsers.

• SNMP-based network management:

– HP PCM/PCM+ — a graphical network management tool that

you can use to manage your entire small to medium-sized network.

Installing the Switch

Included Parts

Installation Precautions

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.

■ Wall-mount the switches with network ports facing up or down.

Do not mount the switches with the ventilation or fan ducts facing up or down.

Cautions ■ When installing the switch, the AC outlet should be near the switch and

should be easily accessible in case the switch must be powered off.

■ Ensure the power source circuits are properly grounded.

■ Use only the AC/DC power adapter and power cord (if applicable),

supplied with the switch. Use of other adapters or power cords, including those that came with other HP Networking products, may result in damage to the equipment.

For those switches that use a power cord, 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 the 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.

■ Ensure 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. 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 45C (113F). This includes a fully-enclosed rack. Ensure the air flow around the sides and back of the switch is not restricted. Leave at least 7.6 cm (3 inches) for cooling.

■ Ensure all port covers are installed when the port is not in use.

Installation Procedures

These steps summarize your switch installation. The rest of this chapter provides details on these steps.

1. Prepare the installation site (page 2-5). Make sure 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. See page

2-3 for some installation precautions.

2. Verify the switch passes self test (page 2-6). Plug the switch into a power source and observe that the LEDs on the switch’s front panel indicate correct switch operation.

3. Mount the switch (page 2-8). The switch can be mounted in a 19-inch telco rack, in an equipment cabinet, on a wall, under a table, or on a horizontal surface.

4. Connect power to the switch (page 2-12). Once the switch is mounted, plug it into the main power source.

5. Connect the network devices (page 2-13). Using the appropriate network cables, connect the network devices to the switch ports.

6. (Optional) Install SFP and SFP+ transceivers (page 2-14). The switch has two slots for installing transceivers. Depending on where you install the switch, it may be easier to install the transceivers first. Transceivers can be hot swapped—they can be installed or removed while the switch is powered on.

7. (Optional) Connect a console to the switch (page 2-15). 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 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.

Installation Procedures

2. Check the LEDs on the switch as described below.

Figure 2-2. Checking the 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. Most of the LEDs go off

and then come on again during phases of the self test.

• For the duration of the self test, the Tes t LED stays on.

When the self test completes successfully:

•The Power, PoE and Fan LEDs remain on.

•The Fault, Locator and Tes t LEDs stay off.

•The Act LED remains on indicating the default port LED mode.

• The port LEDs on the front of the switch go into their normal opera-

tional 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 (Act), the Mode LEDs should be blinking indicating port activity.

– 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 Te st LEDs stay on for more than 60 seconds or they start flashing, the self test has not completed correctly. Refer to chapter 4,

Installation Procedures

6. Installing or Removing SFPs

You can install or remove an SFP from an SFP slot without having to power off the switch. Use only HP SFPs (see Table 1-1 on page 1-3).

Caution Hot swapping transceivers is supported. You can install or remove a

transceiver with the switch powered on, a reset will not occur. However, rapid hotswaps are not recommended. Wait a few seconds for the Mode LED to turn on (during initialization), and then turn off.

Notes Ensure the network cable is NOT connected when you install or remove an

SFP.

Caution Use only supported genuine HP SFPs with your switch. Non-HP SFPs are not

supported, and their use may result in product malfunction. Should you require additional HP SFPs, contact your HP Networking Sales and Service Office or authorized dealer.

Installing the SFPs:

Remove the protective plastic cover and retain it for later use. Hold the SFP by its sides and gently insert it into any of the slots on the switch until the SFP clicks into place.

WARNING The fiber-optic HP SFPs are Class 1 laser devices. Avoid direct eye

exposure to the beam coming from the transmit port.

Figure 2-8. Installing an SFP

2-14

Installing the Switch

Installation Procedures

Removing the SFPs

Note You should disconnect the network cable from the SFP before removing it

from the switch.

Depending on when you purchased your HP SFP, it may have either of three different release mechanisms: a plastic tab on the bottom of the SFP, a plastic collar around the SFP, or a wire bail.

To remove the SFPs that have the plastic tab or plastic collar, push the tab or collar toward the switch until you see the SFP release from the switch (you can see it move outward slightly), and then pull it from the slot.

To remove the SFPs that have the wire bail, lower the bail until it is approximately horizontal, and then using the bail, pull the SFP from the slot.

Replace the protective plastic cover on the SFP.

Connecting Cables to SFPs

If you have any SFPs installed in the switch, the type of network connections you will need to use depends on the type of SFPs you have installed. See the table on page 1-3, and appendix A, “Specifications”, for the SFP cabling information.

For SFP 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 Link LED for that port should go on. If the port Link LED does not go on when the network cable is connected to the port, see “Diagnosing with the LEDs” in chapter 4, “Troubleshooting”.

7. (Optional) Connect a Console to the Switch

The switches have 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

2-15

Installing the Switch

Installation Procedures

The console can be accessed through these methods:

■ Out-of-band: The switches come with a serial cable for connecting a PC

or VT-100 terminal, to be used as a console, directly to the switch’s RJ-45 Console Port.

There is also the option of using a USB cable (not supplied) to connect the switch’s Micro USB Console Port to a PC. To use the USB Console Port, you must first download a USB driver to the PC. See the Note on

page 2-17 for more information.

Note that you cannot use both the RJ-45 Console Port and USB Console Port at the same time. When the USB Console Port is connected to a live PC, it has priority over the RJ-45 Console Port.

By default, the RJ-45 console port is active (accepts input). To activate the USB console port, connect it to a live PC. If the USB console session is closed by the inactivity timer, the RJ-45 console port becomes active again to allow remote access via a terminal server. To reactivate the USB console port, unplug it, then reconnect it to a live PC.

■ 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, “Configuring the Switch”, in the Management and Configuration Guide, which is on the HP Web site at

www.hp.com/networking/support.

2-16

The switches can simultaneously support one out-of-band console session through a Console Port and in-band Telnet console sessions.

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 off

■ for the Windows Terminal program, also disable (uncheck) the “Use

Function, Arrow, and C

■ for the Hilgraeve HyperTerminal program, select the “Terminal keys”

option for the “Function, arrow, and ctrl keys act as” parameter

trl Keys for Windows” option

Installing the Switch

Installation Procedures

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.

Note USB Console Port Driver Download. When using the Micro USB Console

Port, the connected PC first requires “virtual COM port” USB drivers to be installed. USB drivers are available for Windows XP, Windows Vista, and Windows 7.

USB console drivers are available at www.hp.com/networking/support. Type a product name (e.g. 2530) or product number in the Auto Search textbox. Select one of the switches from the drop-down list. Click the Display selected button. From the options that appear, select Software downloads (on the right-hand side). Download the “USB Console Port Drivers and Information.”

Direct Console Access

To connect a console to the switch, follow these steps:

1. Connect the PC or terminal to the switch’s Console Port using the console cable included with the switch. (If your PC or terminal has a 25-pin serial connector, first attach a 9-pin to 25-pin straight-through adapter at one end of the console cable.)

Alternatively, connect the PC to the switch’s Micro USB Console Port using a USB cable (not supplied). male type A (4-pin) to male micro-B (5-pin) connectors. The maximum allowable length is 5 meters.

To use the USB Console Port, you must first download a USB driver to the PC. See the Note at the top of this page for more information.

Installing the Switch

Sample Network Topologies

This section shows a few sample network topologies for implementing the Switches. For more topology information, see the HP networking products Web site, www.hp.com/networking.

As a Desktop Switch Implementing PoE

Figure 2-10. Basic desktop configuration

The 2530-24G-PoE+-2SFP+, 2530-48G-PoE+-2SFP+ switches are designed to be used as desktop switches to which end nodes, printers and other peripherals, and servers are directly connected, as shown in the above illustration. The switches can also supply PoE+ power to end devices such as IP telephones.

2-19

Installing the Switch

Sample Network Topologies

As shown in the above illustration, the IP telephones can be connected in line, that is, between the switch and the end device, in this case a PC. The IP telephones have two ports, one in and one out. Therefore the phone receives voice and power from the switch and the PC can send and receive data through the phone to the switch.

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 Auto-MDIX feature on these Switches.

As a Segment Switch Implementing PoE

2-20

Figure 2-11. Segment network configuration with PoE switches

These Switches also work well as segment switches. That is, with their high performance, they can be used for interconnecting network segments— simply connect the network devices that form those segments to the Switches.

In the illustration above, 2530-24G-PoE+-2SFP+ Switches with PCs, printers, and local servers attached, are both connected to a non-PoE switch. The devices attached to the two 2530-24G-PoE+-2SFP+ Switches can now

Installing the Switch

Sample Network Topologies

communicate with each other through the non-PoE switch. They can also all communicate with the server that is connected to a 1000BASE-T port on the 2530-24G-2SFP+ Switch.

As shown in the illustration above, the IP telephones have been inserted in between the 2530-24G-PoE+-SFP+ Switch and the PCs, and wireless access points (WAPs) have been connected to the 2530-24G-PoE+-2SFP+ Switches. Both the telephones and WAPs will receive PoE+ power from each of the switches. Only devices directly connected to PoE switches can receive PoE power. Devices connected to the non-PoE switch cannot receive PoE power.

Because these Switches have the Auto-MDIX feature, the connections between the switches 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 connections between the switches are through fiber-optic cabling connected to Gigabit transceivers. All the devices on these network segments can access other network resources that are connected elsewhere on the network. Always remember when connecting fiber-optics that all components match in specification.

Installing the Switch

Sample Network Topologies

Stacking the Switch

These Switches 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 this 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.

For more information on stacking your switch, see the Management and

Configuration Guide, which is on the HP Web site at www.hp.com/networking/

support.

2-22

Configuring the Switch

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 Web browser interface, please see the Management and Configuration Guide, which is on the HP Web site at www.hp.com/networking/support.

Recommended Minimal 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.

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. 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.

For more information on IP addressing, refer to “IP Configuration” in the Management and Configuration Guide.

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.

Configuring the Switch

Recommended Minimal Configuration

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 chapter 2, connect a terminal device to the switch and display the switch console command line interface (CLI) prompt (the default display).

The CLI prompt appears, for example:

2. At the prompt, enter the setup command to display the Switch Setup screen. The following illustration shows the Setup screen with the default settings.

Using the IP Address for Remote Switch Management

Configuring the Switch

Using the IP Address for Remote Switch Management

With your switch, 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:

HP-2530-24G-PoEP#

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

These Switches 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.

For more information on using the Web browser interface, please see the Management and Configuration Guide.

An extensive help system is also available for the Web browser interface. To access the Help system, access to the Internet is required. Otherwise, the Help files must be downloaded to a local management server.

Troubleshooting

This chapter describes how to troubleshoot the Switches. This document describes troubleshooting mostly from a hardware perspective. You can perform more in-depth troubleshooting on these devices using the software tools available with the switches, including the full-featured console interface, the built-in Web browser interface, and HP PCM, the SNMP-based HP network management tool. For more information, see the chapter “Troubleshooting” in the Management and Configuration Guide, which is on the HP Web site at www.hp.com/networking/support.

This chapter describes the following:

■ basic troubleshooting tips (page 4-1)

■ diagnosing with the LEDs (page 4-4)

■ proactive networking tools (page 4-9)

■ hardware diagnostic tests (page 4-10)

■ restoring the factory default configuration (page 4-12)

■ downloading new software to the Switches (page 4-13)

■ HP Customer Support Services (page 4-13)

Basic Troubleshooting Tips

Most problems are caused by the following situations. Check for these items first when starting your 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 operates in one of two ways to determine the link speed and the communication mode (half duplex or full duplex):

• If the connected device is also configured to Auto, the switch will

automatically negotiate both link speed and communication mode.

• 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.

4-1

Troubleshooting

Basic Troubleshooting Tips

Caution Because the Switches behave in this way (in compliance with the IEEE

802.3 standard), if a device connected to the switch has a fixed configu-

ration 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.

Ensure all devices connected to these Switches 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 the cables 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 A,

Specifications”

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.

“Cabling and Technology Information

4-2

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, 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 or the Web browser interface.

The se Switches also support 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 HP Web site at

www.hp.com/networking/support.

Basic Troubleshooting Tips

■ Check the port configuration. A port on your switch 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.

The switch is not plugged into an active AC power source, or the switch’s power supply may have failed.

A switch hardware failure has occurred. All the LEDs will stay on indefinitely.

The switch has experienced a software failure during self test.

One of the switch cooling fans may have failed.

1. Verify 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 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 network reseller, or use the electronic support services from HP to get assistance.

Try power cycling the switch. If the fault indication reoccurs, the switch may have failed. Call your HP-authorized network reseller, or use the electronic support services from HP to get assistance.

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 or by typing “Show log” at the Manager command prompt (#).

If necessary to resolve the problem, contact your HP-authorized network reseller, or use the electronic support services from HP to get assistance.

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 of the fans has failed. In switches with multiple fans the switch 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 network reseller, or use the electronic support services from HP to get assistance.

➎

The network port for which the LED is flashing 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 network reseller, or use the electronic support services from HP to get assistance.

If the port is an SFP, verify that it is one of the SFPs supported by the switch. Unsupported SFPs will be identified with this fault condition. The supported SFPs are listed in Chapter 1, “Introducing the Switch” on page 1-3. The SFPs are also tested when they are “hot-swapped”—installed or changed while the switch is powered on.

To verify the port has failed, remove and reinstall the SFP without powering off the switch. If the port fault indication reoccurs, you will have to replace the SFP. Check the event log to see why the SFP failed.

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 you have used the correct cable type for the connection: – For twisted-pair connections to the fixed 10/100/1000 ports, if the port is configured

to “Auto” (auto negotiate), either straight-through or crossover cables can be used because of the switch’s “Auto-MDIX” feature and the Auto MDI/MDI-X feature of the 10/100/1000-T port.

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.

– For fiber-optic connections, verify 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 1000BASE-T connections, verify 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 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 to determine the state of the port and re-enable the port if necessary.

• Verify 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 fiberoptic, 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.

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 HP Web site at www.hp.com/networking/

Proactive Networking

These Switches have 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:

■ A graphical Web browser interface 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 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.

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 HP Web site at www.hp.com/networking/

Troubleshooting

Hardware Diagnostic Tests

Testing the Switch by Resetting It

If you believe 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. 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 flashing, there may be a problem with the switch.

4-10

See

“Diagnosing with the LEDs” on page 4-4 for information on interpreting the LED

patterns.

Checking Console Messages

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 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 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 after entering the Menu command.

Hardware Diagnostic Tests

Troubleshooting

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 must be compatible with the appropriate standards. To verify 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 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 HP Web site at www.hp.com/

networking/support.

Testing End-to-End Network Communications

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.

4-11

Troubleshooting

Restoring the Factory Default Configuration

As part of your troubleshooting process on the Switch, it may become necessary to return the switch configuration to the factory default settings. This 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 HP Web site at

www.hp.com/networking/support.

4-12

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:

1. Using pointed objects, simultaneously press both the Reset and Clear buttons on the front of the switch. The power and fault lights come on.

2. Continue to press the Clear button while releasing the Reset button.

3. When the Self Test LED begins to flash, 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.

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).

A-4

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. 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.

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.

Mode Conditioning Patch Cord

Specifications

Mode Conditioning Patch Cord

The following information applies to installations in which multimode fiberoptic cables are connected to a Gigabit-LX port. Multimode cable has a design characteristic called “Differential Mode Delay”, which requires the transmission signals be “conditioned” to compensate for the cable design and thus prevent resulting transmission errors.

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 those ports, usually CRC or FCS errors, you may need to install one of these patch cords between the fiber-optic port in your switch and your multimode fiber-optic network cabling, at both ends of the network link.

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 in this appendix, 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.

Installing the Patch Cord

As shown in the illustration below, connect the patch cord to the transceiver 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.

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.

Make sure you purchase a patch cord that has appropriate connectors on each end, and has multimode fibers that match the characteristics of the multimode fiber in your network. Most important, the core diameter of the multimode patch cord must match the core diameter of the multimode cable infrastructure (either 50 or 62.5 microns).

Twisted-Pair Cable/Connector Pin-Outs

Specifications

Twisted-Pair Cable/Connector Pin-Outs

The Auto-MDIX Feature: In the default configuration, “Auto”, the fixed 10/ 100/1000BASE-T ports on the Switches all automatically detect the type of port on the connected device and operate as either an MDI or MDI-X port, whichever is appropriate. So for any connection, a straightthrough twisted-pair cable can be used—you no longer have to use crossover cables, although crossover cables can also be used for any of the connections. (The 10/100/1000-T ports support the IEEE 802.3ab standard, which includes the “Auto-MDIX” feature.)

If you connect the Switch twisted-pair port to another switch or hub, which typically have MDI-X ports, the Switch port automatically operates as an MDI port. If you connect it to an end node, such as a server or PC, which typically have MDI ports, the Switch port operates as an MDI-X port. In all cases, you can use standard straight-through cables or crossover cables.

If you happen to use a correctly wired crossover cable, though, the switch will still be able to automatically detect the MDI/MDI-X operation and link correctly to the connected device.

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.

■ 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.

A-9

Specifications

Twisted-Pair Cable/Connector Pin-Outs

■ 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.

■ To provide Power over Ethernet to the access point, all 4 pairs must be

connected for any network cable attached to this port; the cable must meet ISO/DIS 11801 Class D requirements and IEEE 802.3af requirements.

Specifications

Straight-through Twisted-Pair Cable for 10 Mbps or 100 Mbps Network Connections

Because of the Auto-MDIX operation of the 10/100 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.

If any of these ports are given a fixed configuration, for example 100 Mbps/ Full Duplex, the ports operate as MDI-X ports, and straight-through cables must be then used for connections to PC NICs and other MDI ports.
