Introducing the Switch

HP Switch 2510G-24 (J9279A)

HP Switch 2510G-48 (J9280A)

The HP Switch 2510G-24 and Switch 2510G-48 are multiport Gigabit switches ideal for building high-performance small business networks. These switches are store-and-forward devices offering low latency for high-speed networking.

The Switch 2510G-24 and Switch 2510G-48 have, respectively, 24 or 48 autosensing 10/100/1000Base-T RJ-45 ports, four dual-personality ports—either auto-sensing 10/100/1000Base-T RJ-45 or mini-GBIC.

The dual-personality ports have either auto-sensing 10/100/1000Base-T RJ-45, or mini-GBIC (SFP, small form factor pluggable) connectivity. If any of the mini-GBIC ports are used the corresponding RJ-45 port will be disabled.

Introducing the Switch

These switches are designed to be used primarily as a high-density wiring closet or desktop switch. These switches can directly connect computers, printers, and servers to provide dedicated bandwidth to those devices, and can build a switched network infrastructure by connecting the switch to hubs, other switches, or routers. In addition, the Switch 2510G Series devices offer full network management capabilities.

Introducing the Switch

Front of the Switch

■ Four dual-personality ports. Use either the 10/100/1000Base-T RJ-45

connector, or install a supported HP mini-GBIC (SFP) for fiber-optic connections. The RJ-45 connectors support the Auto-MDIX feature, which means you can use either straight-through or crossover twisted-pair cables to connect any network device to the switch.

Dual-Personality Port Operation. By default, the RJ-45 connectors 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.

Console Port

This port is used to connect a console to the Switch 2510G Series devices by using the supplied RJ45 to DB9 cable with the switch. The console port is located on the front of 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.

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.

The Locator LED is used to locate a specific switch in an area full of switches. The LED can be set to be on solid or flash for a specified number of minutes (1-1440). The default is 30 minutes. Use the command “chassislocate”.

• if the port LED is on, the port is enabled and receiving a link indication from the

connected device.

• if the port LED is off, the port has no active network cable connected, or is not

receiving link beat or sufficient light. Otherwise, the port may have been disabled through the switch console, the web browser interface, or HP Manager.

■ Each port has a Link LED. If it is lit, the port has a link. If the Link LED is

flashing, the port has failed its self test. The Fault and Test LEDs will be flashing simultaneously.

■ If the Activity (Act) indicator LED is lit, each port 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 port LEDs light for those

ports that are operating in full duplex.

■ If the Speed (Spd) indicator LED is lit, the port LEDs behave as follows

to indicate the connection speed for the port:

• Off = 10 Mbps

• Flashing = 100 Mbps (the flashing behavior is a repeated on/off cycle once every 0.8 sec.)

• On = 1000 Mbps

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

The pin operation of each port is automatically adjusted for the attached device: if the switch detects that another switch or hub is connected to the port, it configures the port as MDI; if the switch detects that an endnode device is connected to the port, it configures the port as MDI-X.

■ automatic learning of the network addresses in each switch’s 8000-

address forwarding table, with configurable address aging value.

■ automatically negotiated full-duplex operation for all 10/100/1000Base-T

RJ-45 ports when connected to other auto-negotiating devices—the miniGBIC ports always operate at full duplex.

■ easy management of the switch 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.

• HP Manager—an SNMP based, graphical network management tool you can use to manage your entire network. this product is included with your new switch.

■ support for the Spanning Tree Protocol to eliminate network loops.

■ support for up to 64 IEEE 802.1Q-compliant VLANs so you can divide the

attached end nodes into logical groupings that fit your business needs.

■ download of new switch software for product enhancements or bug fixes.

Installation Precautions:

Follow these precautions when installing the Switch 2510G Series devices.

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 either side of the

switch (air vents) facing downward.

Cautions ■ Ensure 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 the cord is adequately sized for the switch’s current requirements. In addition, 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, the AC outlet should be near the switch and

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

■ 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. 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 45C (113F).

■ 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. See Figure 2-1 for the air flow direction.

Summary

Follow these steps to install the switch. The rest of this chapter provides details on these steps.

1. Prepare the installation site (page 2-5). Ensure the physical environment 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 2-7). The switch has four 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 mini-GBICs can be hot swapped—they can be installed or removed while the switch is powered on.

3. Verify the switch passes self test (page 2-9). Plug the switch into a power source and observe the LEDs on the switch’s front panel that they indicate correct switch operation.

4. Mount the switch (page 2-11). The Switch 2510G Series devices can be mounted in a 19-inch telco rack, in an equipment cabinet, on a horizontal surface, or on the wall.

5. Connect power to the switch (page 2-14). Once the switch is mounted, plug it into the nearby main power source.

Installation Procedures

2. Installing or Removing mini-GBICs (SFPs)

You can install or remove a mini-GBIC or SFP from a mini-GBIC slot without having to power off the switch. Use only HP mini-GBICs and transceivers.

Notes ■ The mini-GBIC slots are shared with the four 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, unless a 100-FX SFP transceiver is installed. The 100-FX SFP transceiver can operate at half duplex.

■ Ensure 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:

■ HP Gigabit-SX-LC mini-GBIC (J4858B, J4858C)

■ HP Gigabit-LX-LC mini-GBIC (J4859B, J4859C)

■ HP Gigabit-LH-LC mini-GBIC (J4860B, J4860C)

■ HP 100-FX SFP-LC Transceiver (J9054B)

Caution Use only supported genuine HP mini-GBICs and transceivers with your

switch. Non-HP mini-GBICs and transceivers are not supported, and their use may result in product malfunction. Should you require additional HP miniGBICs or transceivers, contact your HP Networking Sales and Service Office or authorized dealer.

Installing the mini-GBICs:

Remove the protective plastic cover and retain it for later use. Hold the miniGBIC by its sides and gently insert it into either of the slots on the switch until the mini-GBIC clicks into place. When the mini-GBIC is installed, the Link LED turns on for 2 seconds to verify correct installation.

WARNING The HP mini-GBICs are Class 1 laser devices. Avoid direct eye expo-

sure to the beam coming from the transmit port.

Installation Procedures

Figure 2-2. Example of installing a mini-GBIC (SFP)

Removing the mini-GBICs

Note The network cable should be disconnected from the mini-GBIC before

removing it from the switch.

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

2-8

To remove the mini-GBICs that have the plastic tab 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.

Replace the protective plastic cover.

Connecting Cables to mini-GBICs

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 2-5, 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”.

Installation Procedures

3. Verify the Switch Passes Self Test

Before mounting the switch in its network location, you should first verify it is working properly by plugging it into a power source and verifying it passes 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.

Figure 2-3. Connecting the power cord

Note The Switch 2510G Series devices do not have a power switch. They are

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. No voltage range settings are 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.

2-10

Figure 2-5. Checking the LEDs on the 2510G-48 (J9280A)

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 may come on again during phases of the self test.

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

Page 29

Installing the Switch

Installation Procedures

When the self test completes successfully:

•The Power and Fan Status LEDs remain on.

•The Fault and Test LEDs go off.

• 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 LEDs

behave according to the Port LED View or LED Mode selected. The default view mode (Link), the LEDs should be on and the Mode LEDs will flicker if there is network activity.

– If the ports are not connected to active network devices, the Link

and Act LEDs will stay off.

If the LED display is different than what is described above, especially if the Fault and Test LEDs stay on for more than 60 seconds or they start flashing, the self test has not completed correctly. Refer to chapter 4, “Troubleshooting” for diagnostic help.

4. Mount the Switch

After the switch passes self test, you are ready to mount the switch in a stable location. The Switch 2510G Series devices can be mounted in these ways:

■ in a rack or cabinet

■ on the wall

■ on a horizontal surface

Rack or Cabinet Mounting

The Switch 2510G Series devices are designed to be mounted in any EIAstandard 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. Secure the rack in accordance with the manufacture’s safety guidelines.

WARNING For safe operation, read the Installation 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, and plan which four holes you will be using in the cabinet and install all four clips. Then proceed to step 2.

Installation Procedures

7. (Optional) Connect a Console to the Switch

The switch 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 comes with a serial cable for connecting a PC

or VT-100 terminal, to be used as a console, directly to the switch.The console cable is a DB-9 to RJ45 connector.

■ 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”, and the Management and Con- figuration Guide, which is available on the HP Web site: www.hp.com/networking/support.

2-16

The Switch 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 C

• 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 save the terminal settings, then reboot the switch and reestablish the console session.

Figure 2-13. Basic desktop configuration

The Switch is designed to be used primarily as a desktop switch to which end nodes, printers and other peripherals, and servers are directly connected, as shown in the above illustration. 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 “Auto-MDIX” features on the Switch.

As a Segment Switch

Figure 2-14. Segment network configuration

The Switch also works well as a segment switch. 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. 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 a 1000Base-T port on the switch.

Because the Switch has the “Auto MDI-X” features, 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.

2-20

Page 39

Installing the Switch

Sample Network Topologies

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.

For example, you could use an HP Switch 5406zl 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 5406zl, the entire switched topology could be connected to a campus backbone, as shown in the illustration above.

Note In the Backbone Switch illustration, the 1000 Mbps fiber-optic connection

between the Switch 2510G-24 and the Switch 5406zl is by way of a Gigabit-SX mini-GBIC installed in the Switch 2510-24 and connected to a Gigabit-SX Module in the Switch 5406zl.

Stacking the Switch

The Switch 2510G Series devices 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.

For more information on stacking Switches, please see the Management and Configuration Guide, which is available on the HP Website: www.hp.com/networking/support.

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 other switch management interfaces (such as the web browser interface), please see the Management and Configuration Guide, which is available on the HP Networking Website 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, which is available on the HP Networking Website www.hp.com/networking/support.

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, which is available on the HP Networking Website www.hp.com/networking/support.

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, for example:

HP Switch 2510G-24#

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 the Switch 2510G Series devices, 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) and disable IP routing.

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 Switch 2510G-24#

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

The Switch 2510G Series devices, 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.

Troubleshooting

This chapter describes how to troubleshoot the Switch 2510G Series devices. This document describes troubleshooting mostly from a hardware perspective. You can perform more in-depth troubleshooting on the Switch 2510G Series devices using the software tools available with the switch, including the full-featured console interface and the built-in web browser interface. For more information, see the chapter “Troubleshooting” in the Management and Configuration Guide, which is available on the HP Networking Website 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 4-8)

■ hardware diagnostic tests (page 4-9)

■ restoring the factory default configuration (page 4-11)

■ downloading new software to the Switch 2510G Series devices (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:

■ 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):

• 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, the link speed, but will default to a communication mode of half duplex.

at half or full duplex, the switch will automatically sense

4-1

Page 50

Troubleshooting

Basic Troubleshooting Tips

Because the Switch 2510G Series devices behave 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 all devices connected to the Switch 2510G Series devices 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, “Twisted-Pair Cable/Connector Pin-Outs”

on page 5 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 on the HP Networking Website,

www.hp.com/networking/support.

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 2510G Series devices, 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 Switch 2510G Series devices 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 available on the HP Networking Website www.hp.com/networking/support.

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 available on the HP Networking Website www.hp.com/networking/support.

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 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.

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.

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.

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 more of the fans has failed. The Switch 2510G-48 has three fans, and the Switch 2510G-24 has two fans and 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 LAN dealer, or use the electronic support services from HP to get assistance. See the Customer Support/Warranty booklet for more information.

The network port

➎

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 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” on page 2-7. The mini-GBICs are also tested when they are “hot-swapped”—installed or changed while the switch is powered on.

To verify 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 miniGBIC.

Diagnosing with the LEDs

Tip Problem Solution

The network

➏

connection is not working properly.

Try the following procedures:

• For the indicated port, verify 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-T 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 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 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 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.

Troubleshooting

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 available on the HP Networking Website www.hp.com/

Proactive Networking

The HP Switch 2510G Series devices 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 log 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 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.

Hardware Diagnostic Tests

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, 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 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.

See “Diagnosing With the LEDs” on page 4-4 for information on interpreting the LED patterns and LED behaviors in chapter one.

Checking Console Messages

Useful diagnostic messages may be displayed on the console screen when the switch is reset. To 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.

4-9

Page 58

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 twistedpair 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 available on the HP Networking Website

www.hp.com/networking/support.

4-10

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.

Restoring the Factory Default Configuration

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 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 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 available on the HP Networking Website www.hp.com/networking/support.

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.

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

3. When the 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.

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 for Gigabit-LX

The following information applies to installations in which multimode fiberoptic cables are connected to a Gigabit-LX port.

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.

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 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.

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.

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.

Figure B-1. Connecting a patch cord

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.

Twisted-Pair Cable/Connector Pin-Outs

The Auto-MDIX Feature: In the default configuration, “Auto”, the fixed 10/ 100Base-TX ports on the Switch 2510G Series 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 MDI/MDI-X” feature, which operates the same way.)

If you connect a Switch 2510G Series twisted-pair port to another switch or hub, which typically have MDI-X ports, the Switch 2510G Series 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 2510G Series port operates as an MDI-X port. In all cases, you can use standard straightthrough 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 Auto-MDIX 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. See “Note on 1000Base-T Cable Require-

ments” 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

Page 68

Switch Ports and Network Cables

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.

Twisted-Pair Cable/Connector Pin-Outs

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.
