HP ProCurve 2910al-48G-PoE+ Switch (J9148A)

The HP ProCurve 2910al Switches are multiport switches that can be used to build high-performance switched networks. These switches are store-andforward devices offering low latency for high-speed networking. The 2910al switches also support Redundant Power Supply and Power over Ethernet technologies.

Throughout this manual, these switches will be referred to as the 2910al Switches or the 2910al-PoE+ Switches.

1-1

Page 10

Introducing the Switch

The 2910al-24G Switch and 2910al-48G Switch have respectively, 24 or 48, auto-sensing 10/100/1000Base-T RJ-45 ports, four dual-personality ports— either auto-sensing 10/100/1000Base-T RJ-45 or mini-GBIC, and two slots are provided in the back of the device to support expansion modules:

■ 2-port (two fixed CX4 ports) 10 Gigabit per second Ethernet (10-GbE)

module.

■ 2-port 10-GbE SFP+ (Small Form Factor Pluggable) module. The specifi-

cation for SFP+ defines the physical and electrical characteristics of this form-factor (size and shape). The form-factor is identical to SFP, but the SFP+ is a 10-Gigabit Ethernet transceiver.

■ 1-port 10-GbE interconnect module.

Table 1-1. These products support optional network connectivity with the

following speeds and technologies:

Introducing the Switch

The 2910al-PoE+ Switches also support Power over Ethernet+ (PoE+) technology. PoE+ offers a higher wattage per port than the previous PoE offering, 30 watts per port instead of 15. The switches support 802.3af standard devices and some pre-standard PoE devices. It also supports the draft version of the 802.3at standard. For a list of these devices, see the FAQs for your switch model. This feature is the default and you must disable it if you do not want to use it. Refer to the Management and Configuration Guide which is on the ProCurve Web site at www.hp.com/go/procurve/manuals.

The dual-personality ports have either auto-sensing 10/100/1000Base-T RJ-45, or mini-GBIC (SFP) connectivity. The mini-GBIC ports do not support PoE. If any of the mini-GBIC ports are used the corresponding RJ-45 port will not be supplied with PoE power and will be disabled. For more information regarding the PoE capabilities of the 2910al Switches, see the ProCurve PoE (Power over Ethernet) Devices Planning and Implementation Guide, which is on the ProCurve Web site at www.hp.com/go/procurve/manuals.

HP ProCurve Redundant/External Power Supplies (RPS/EPS) can be connected to the 2910al Switches for redundant 12 V system power (RPS) and to provide for additional PoE+ provisioning. For RPS power, the 2910al Switches can be connected to either an HP ProCurve 620 RPS/EPS or HP ProCurve 630 Redundant and/or External Power Supply. But, for additional PoE+ EPS power, only the HP ProCurve 630 RPS/EPS can be used. The 620 does not provide 54 V for PoE+, only 50 V for PoE, and the 2910al Switches do not support connections to the 620 for EPS.

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 2910al Switches offer full network management capabilities.

Network Ports

■ 24 or 48 auto-sensing 10/100/1000Base-T ports.

All these ports have the “Auto MDIX” feature, which means you can use either straight-through or crossover twisted-pair cables to connect any network devices to the switch.

■ On the 2910al devices there are four dual-personality ports. Use either the

10/100/1000Base-T RJ-45 connector, or install a supported ProCurve miniGBIC (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.

The RJ-45 connector also supplies PoE+ power until a mini-GBIC is installed. The PoE+ power is turned off when a mini-GBIC is plugged in.

■ Two expansion slots. These switches provide two slots in the back of the

device that can accept any of the al modules. The module provides port connectivity for 10 gigabit speed. The module ports provide connectivity through either copper or fiber optic media.

Switch Features

The features of the 2910al Switch include:

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

■ Four dual-personality ports—either the auto sensing 10/100/1000Base-T

RJ-45 or the mini-GBIC can be used for each port.

■ Two slots (optional al module slot) are provided in the back of the device

to support a series of transceivers to provide connectivity to other switch boxes, to a 10 Gigabit concentrator or to any Ethernet compatible uplink.

■ An auxiliary (USB) port for processing a USB command file.

■ The Switches can be connected to a ProCurve RPS/EPS and receive

redundant power from that unit. If the internal power supply in the switch fails, the RPS/EPS unit will immediately provide all the power necessary to keep the switch running.

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

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

■ IEEE 802.3ab Auto MDIX on all 10/100/1000 twisted-pair ports, meaning

that all connections can be made using straight-through twistedpair 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 end-node device is connected to the port, it configures the port as MDI-X. If both devices use Auto-MDIX, the configuration is randomly selected.

■ Automatic learning of the network addresses in each switch’s 2048-

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—the mini-GBIC ports always operate at full duplex.

■ Easy management of the switch through several available interfaces:

Installation Precautions:

Follow these precautions when installing the 2910al Switches.

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.

■ Do not wall mount any of the 2910al Switches.

Cautions ■ If the switch is to be shipped in a rack, be sure to use only an HP 10K rack.

Mount the switch using rail kit part number 356578-B21 and shelf kit AB469A. Both kits must be used. Otherwise you will void the warranty.

■ 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 and power supply, 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 and power supply.

■ 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 55C (131F)

■ Ensure the air flow around the sides 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.

Installation Procedures

Summary

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. See page 2-3 for some installation precautions.

2. Verify the switch passes self test (page 2-5). Plug the switch into a power source and observe that the LEDs on the switch’s front panel indicate correct switch operation. When self test is complete, unplug the switch.

3. (Optional) Install a module (page 2-8).

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

5. (Optional) Install a transceiver (page 2-14). If you have installed a module, you can now install one or two transceivers.

6. (Optional) Install mini-GBICs and SFPs (page 2-16). The switch has four slots for installing mini-GBICs. Depending on where you will mount the switch, it may be easier to install the mini-GBICs first. Mini-GBICs can be installed or removed while the switch is powered on.

7. Connect power to the switch (page 2-18). Once the switch is mounted, plug it into the nearby main power source.

Installation Procedures

8. (Optional) Connect an external power supply (page 2-18). You may wish to use an HP ProCurve external power supply, either the 620 RPS/ EPS or the 630 RPS/EPS with your 2910-PoE+ switch. To do so you must connect the external power supply using the RPS or EPS cables supplied with these devices.

9. (Optional) Connect a console to the switch (page 2-24). You may wish to modify the switch’s configuration, for example, to configure an IP address so it can be managed using a web browser, from an SNMP network management station, or through a Telnet session. Configuration changes can be made easily by using the included console cable to connect a PC to the switch’s console port.

10. Connect the network cables (page 2-27). Using the appropriate network cables, connect the network devices to the switch ports.

At this point, the switch is fully installed. See the rest of this chapter if you need more detailed information on any of these installation steps.

1. Prepare the Installation Site

Cabling Infrastructure - Ensure the cabling infrastructure meets the necessary network requirements. See Appendix C “Cabling and Technology

Information” for more information.

■ Installation Location - Before installing the switch, plan its location

and orientation relative to other devices and equipment:

• In the front of the switch, leave at least 7.6 cm (3 inches) of space for

the twisted-pair and fiber-optic cabling.

• In the back of the switch, leave at least 3.8 cm (1 1/2 inches) of space

for the power cord and other cabling.

2. 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.

LED Behavior:

During the self test:

• Initially, all the status, LED Mode and port LEDs are on for most of the duration of the test.

• Most of the LEDs go off and then may come on again during phases of the self test. For the duration of the self test, the Test LED stays on.

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 operational mode: – If the ports are connected to active network devices, the LEDs

behave according to the LED Mode selected. In the default view mode (Link), the LEDs should be on.

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

Installation Procedures

6. (Optional) Install Mini-GBICs and SFPs

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

When a mini-GBIC or SFP transceiver is inserted the switch authenticates it. This can take 1-3 seconds, with the worst case being 5 seconds. If the miniGBIC or SFP transceiver is removed before the authentication completes a self test failure will be reported.

Caution Use only supported genuine ProCurve mini-GBICs with your switch. Non-

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

Notes ■ Hot swapping mini-GBICs and 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 5 seconds between Hotswaps.

■ Each of the four mini-GBIC slots is shared with the associated 10/100/

1000Base-T RJ-45 port. If a mini-GBIC is installed in a slot, the associated RJ-45 port is disabled.

■ The mini-GBIC ports operate only at full duplex. Half duplex operation is

not supported.

■ Inserting a 10-GbE transceiver (SFP+) into a 1 gigabit (mini-GBIC) slot,

will generate an event log message, “Transceiver type not supported by this port”, and the transceiver will not function. The reverse is true also, inserting a 1 gigabit (mini-GBIC) transceiver into a 10-GbE slot will generate an event log message and the transceiver will not function.

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

a mini-GBIC unless you are using a Direct Attach Cable (DAC).

Installation Procedures

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.

7. Connect the Switch to a Power Source

1. Plug the included power cord into the switch’s power connector and into a nearby AC power source.

2. Re-check the LEDs during self test. See “LED Behavior” on page 2-7. Also check the LEDs for any accessories you may have installed.

8. (Optional) Connect an External Power Supply

The 2910al Switches support two types of external power supplies:

■ The J8696A, HP ProCurve 620 Redundant and External Power Supply (620

RPS/EPS) for RPS power only. The 2910al switches support the RPS or the redundant portion of the 620 RPS/EPS. Redundant power to one of up to two switches can be supplied to back up the internal switch power supply in case of the internal power supply fails. If it should fail, power will be supplied from the 620 RPS/EPS.

■ The J9443A, HP ProCurve 630 Redundant and/or External Power Supply

(HP ProCurve 630 RPS/EPS) for RPS and EPS power. The 2910al switches support both the RPS and the EPS of the HP ProCurve 630 RPS/EPS.

These external power supplies are unmanaged power supplies that only provide information by way of the LEDs.

RPS Operation

The RPS portion of the 620 RPS/EPS and the HP ProCurve 630 RPS/EPS monitors the power signal from the switch by detecting that either the 620 RPS/EPS or HP ProCurve 630 RPS/EPS is connected to a switch with an RPS cable. When the power from the switch is no longer detected, the external power supply will provide power to the switch within 1 millisecond. AC power must be provided to the switch prior to the RPS being able to provide power. Software will enable RPS capability, thus boot must be complete.

2-18

Installation Procedures

These external power supplies support hot plugging of the RPS cable without causing a reboot of the switch or causing the power supply in either of the power supplies, or switch to shut down temporarily or permanently. For more information refer to the documentation for the external power supplies located on the ProCurve Web site at www.hp.com/go/procurve/manuals.

Operating Characteristics of the 620 RPS/EPS (J8696A)

The 620 RPS/EPS has two RPS ports, each of which can provide redundant +12V power to a connected switch. If a switch with no AC power is connected to an operating 620 RPS/EPS, the switch will not power on. For the switch to receive power from the external power supply, the switch must first be powered up then connected to the external power supply.

For redundant AC power, connect the 620 RPS/EPS to the switch using one of the supplied RPS cables. RPS cables are 2 meters (6.56 feet) in length.

The 620 RPS/EPS also has two EPS Ports which can not be used with the 2910al Switches.

620 RPS/EPS LEDs

The 620 RPS/EPS LEDs are located on the front and back of the device. The following illustration shows an example of the back of the 620 RPS/EPS. There are two dual colored (green/orange) LEDs for each RPS and EPS port:

The HP ProCurve 630 RPS/EPS has one RPS port, which can provide redundant +12V power to a connected switch. If a switch with no AC power is connected to an operating HP ProCurve 630 RPS/EPS, the switch will not power on. For the switch to receive power from the external power supply, the switch must first be powered up then connected to the external power supply. For redundant AC power, connect the HP ProCurve 630 RPS/EPS to the switch using the supplied RPS cable. The RPS cable is 2 meters (6.56 feet) in length.

The HP ProCurve 630 RPS/EPS also has one EPS Port which can supply backup or extra PoE+ power at 54V to the 2910al Switch.

HP ProCurve 630 RPS/EPS LEDs

The HP ProCurve 630 RPS/EPS LEDs are located on the front and back of the device. The following illustration shows an example of the back of the HP ProCurve 630 RPS/EPS. There are two dual colored (green/orange) LEDs for each RPS and EPS port:

HP ProCurve 630 RPS/EPS Connectivity

This section shows the recommended connection topology using the HP ProCurve 630 RPS/EPS. The HP ProCurve 630 RPS/EPS can provide backup power support for only one ProCurve switch. In the illustration below, the ProCurve Switch 2910 is connected to the RPS and EPS ports on a HP ProCurve 630 RPS/EPS.

Figure 2-18. Connecting RPS/EPS to a switch

9. (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.

■ In-Band: Access the console using Telnet from a PC or UNIX station on

the network, and a VT-100 terminal emulator. This method requires that you first configure the switch with an IP address and subnet mask by using either out-of-band console access or through DHCP/Bootp. For more information on IP addressing and on starting a Telnet session, see chapter 3, “Getting Started With Switch Configuration”, and the Man- agement and Configuration Guide, which is on the HP ProCurve Web site at www.hp.com/go/procurve/manuals.

The Switch can simultaneously support one out-of-band console session through the Console Port and one in-band Telnet console session.

Installation Procedures

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 C

trl Keys for Windows” option

trl 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, save your changes, then change the terminal settings, then reboot the switch and reestablish the console session.

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.)

2. Turn on the terminal or PC’s power and, if using a PC, start the PC terminal program.

3. Press

[Enter] two or three

times and 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:

on the switch or to any mini-GBICs you have installed in the switch.

Using the RJ-45 Connectors

To connect :

Push the RJ-45 plug into the RJ-45 jack until the tab on the plug clicks into place. When power is on for the switch and for the connected device, the Link LED for the port should light to confirm a powered-on device (for example, an end node) is at the other end of the cable.

If the Link LED does not go on when the network cable is connected to the port, see “Diagnosing with the LEDs” on

page 4-4, in chapter 5,

“Troubleshooting”.

To disconnect:

Press the small tab on the plug and pull the plug out of the jack.

Connecting Cables to mini-GBICs

Note Each of the four mini-GBIC slots is shared with the associated 10/100/

1000Base-T RJ-45 port. If a mini-GBIC is installed in a slot, the associated RJ45 port is disabled.

If you have any mini-GBICs installed in the switch, the type of network connections you will need to use depends on the type of mini-GBICs you have installed. See Appendix C “Cabling and Technology Information” for more information, 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” on page 4-4 in chapter 5, “Troubleshooting”.

Getting Started With Switch

Configuration

Getting Started With Switch Configuration

This chapter is a guide for using the console Switch Setup screen to quickly assign an IP (Internet Protocol) address and subnet mask to the switch, set a Manager password, and, optionally, configure other basic features.

For more information on using the switch console and the other switch management interfaces: the web browser interface and the SNMP management tool, ProCurve Manager, please see the Management and Configuration Guide, which is on the ProCurve Website at www.hp.com/go/procurve/manuals.

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, such as ProCurve Manager. For a listing of switch features available with and without an IP address, refer to “How IP Addressing Affects Switch Operation” in the Management and Configuration Guide, which is on the ProCurve Website at www.hp.com/go/procurve/manuals.

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

Using the Console Setup Screen

Note By default, the switch is configured to acquire an IP address configuration

from a DHCP or Bootp server. To use DHCP/Bootp instead of the manual method described in this chapter, see “DHCP/Bootp Operation” in the Management and Configuration Guide, which is on the ProCurve Website at

www.hp.com/go/procurve/manuals.

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:

ProCurve Switch 2910al-48G#

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.

Where to Go From Here

The above procedure configures your switch with a Manager password, IP address, and subnet mask. As a result, with the proper network connections, you can now manage the switch from a PC equipped with Telnet, a web browser interface, or from an SNMP-based network management station using a tool such as ProCurve Manager.

Some basic information on managing your switch is included in the next section. For more information on the console, web browser, and SNMP management interfaces and all the features that can be configured on the al switches, see the Management and Configuration Guide, which is on the ProCurve Website at www.hp.com/go/procurve/manuals.

To Recover from a Lost Manager Password

If you cannot start a console session at the manager level because of a lost Manager password, you can clear all passwords and user names by getting physical access to the switch and pressing and holding the Clear button for a full second.

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:

ProCurve Switch 2910al-48G#

Enter help or ? to see a list of commands that can be executed at the prompt. Entering any command followed by help provides more detailed context help information about the command. Entering any command followed by ? displays a list of options that are available at that point in the command entry.

Starting a Web Browser Session

Your Switch 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.

Troubleshooting

This chapter describes how to troubleshoot your switch. This document describes troubleshooting mostly from a hardware perspective. You can perform more in-depth troubleshooting on the switch using the software tools available with the switch, including the full-featured console interface, the built-in web browser interface, and ProCurve Manager, the SNMP-based network management tool. For more information, see the chapter “Troubleshooting” in the Management and Configuration Guide, which is on the ProCurve Website at www.hp.com/go/procurve/manuals.

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 Switch Software (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

• If the connected device has a fixed configuration, for example

automatically negotiate both link speed and communication mode.

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 66

Troubleshooting

Basic Troubleshooting Tips

Because the switch behaves 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.

Make sure that all devices connected to the switch are configured to auto negotiate, or are configured to connect at half duplex (all hubs are configured this way, for example).

■ Faulty or loose cables. Look for loose or obviously faulty connections.

If they appear to be OK, make sure the connections are snug. If that does not correct the problem, try a different cable.

■ Non-standard cables. Non-standard and miswired cables may cause

network collisions and other network problems, and can seriously impair network performance. Use a new correctly-wired cable or compare your cable to the cable in appendix B, “Cables and Connectors” for pinouts and correct cable wiring. A category 5 cable tester is a recommended tool for every 100Base-TX and 1000Base-T network installation.

■ Improper Network Topologies. It is important to make sure you have

a valid network topology. Common topology faults include excessive cable length and excessive repeater delays between end nodes. If you have network problems after recent changes to the network, change back to the previous topology. If you no longer experience the problems, the new topology is probably at fault. Sample topologies are shown at the end of chapter 2 in this book, and some topology configuration guidelines can be found online on the ProCurve Website at www.hp.com/go/procurve/

manuals.

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 only one of the redundant paths is active at any time, thus avoiding data path loops. Spanning Tree can be enabled through the switch console, the web browser interface, or ProCurve Manager.

The 2910al Switch devices 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 ProCurve Website at www.hp.com/go/procurve/manuals.

Page 67

Troubleshooting

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, which is on the ProCurve Website at www.hp.com/go/procurve/manuals.

For more information on possible network problems and their solutions, refer to the technical note “Troubleshooting LAN Performance and Intermittent Connectivity Problems”, which can be found on the ProCurve Website,

Diagnosing with the LEDs

➊

➋

➌

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

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

The switch has experienced a software failure during self test.

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 ProCurve authorized LAN dealer, or use the electronic support services from ProCurve 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 ProCurve 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 ProCurve authorized LAN dealer, or use the electronic support services from ProCurve to get assistance. See the Customer Support/Warranty booklet for more information.

➍

➎

One or both of the switch cooling fans may have failed.

The network port for which the LED is flashing has experienced a self test or initialization failure.

If the Mdl Status LED is flashing, the affected port is on the al Module.

Try disconnecting power from the switch and wait a few moments. Then reconnect the power to the switch and check the LEDs again. If the error indication reoccurs, one or both of the fans has failed. The switch has two fans and may continue to operate under this condition if the ambient temperature does not exceed normal room temperature, but for best operation, the switch should be replaced. Contact your ProCurve authorized LAN dealer, or use the electronic support services from ProCurve to get assistance. See the Customer Support/Warranty booklet for more information.

Try power cycling the switch. If the fault indication reoccurs, the switch port may have failed. Call your ProCurve authorized LAN dealer, or use the electronic support services from ProCurve to get assistance. See the Customer Support/Warranty booklet for more information.

If the port is a pluggable, verify it is one of the pluggables supported by the switch. Unsupported pluggables will be identified with this fault condition. The supported miniGBICs are listed in Chapter 2, “Installing the Switch” on page 2-1, supported transceivers are listed in Appendix B, Module Specifications. 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 mini-GBIC.

The network 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 or 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 “HP 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 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, or ProCurve Manager network management software 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 othe r procedures don’t resolv e 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 oper ation of the Spanning Tree, LAC P, or IGMP features.

An RPS is connected but the switch has experienced a fault.

An EPS is connected but the switch has experienced a fault.

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 P roCurve Website at www.hp.com/go/procurve/

manuals.

Make sure also, the device at the other end of the connection is indicating a good link to the switch. If it is not, the problem may be with the cabling between the devices or the connectors on the cable.

Check the RPS unit to make sure it is plugged in to an active power source. If this is ok but the LEDs are still flashing, the power supply in the RPS unit may have failed. Try reversing R1 and R2 power cords on the 620 RPS/EPS. Also check the log files of the connected switch for more information. This condition can also be caused by an RPS unit fan failure or an over temperature condition. If necessary to resolve the problem, contact your ProCurve authorized LAN dealer, or use the electronic support services from ProCurve to get assistance. See the Customer Support/Warranty booklet for more information.

Check the EPS unit to make sure it is plugged in to an active power source. If this is ok but the LEDs are still flashing, the power supply in the EPS unit may have failed.

Proactive Networking

The ProCurve 2910al 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 perfor-

mance 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:

■ ProCurve Manager - an SNMP-based network management tool that is

included with your switch.

■ A graphical web browser interface that you can use to manage your switch

from a PC running a supported web browser, for example Microsoft Internet Explorer, and Netscape Communicator.

■ A full-featured easy-to-use console interface that you can access by

connecting a standard terminal or PC running a terminal emulator to the switch’s console port. The cable to make that connection is provided with your switch. The console interface is also accessible through a Telnet connection.

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 ProCurve Website at www.hp.com/go/

procurve/manuals.

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 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.

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. As described in chapter 2 under step 7, “Connect a Console to the Switch”, connect a PC running a VT-100 terminal emulator program or a standard VT-100 terminal to the switch’s Console Port and configure it to run at 9600 baud, and with the other terminal communication settings shown on

page 2-25. 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.

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 on the ProCurve Website at www.hp.com/

go/procurve/manuals.

These tests can also be performed from an SNMP network management station running a program that can manage the switch, for example, ProCurve Manager.

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.

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 on the ProCurve Website at www.hp.com/go/procurve/manuals.

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 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.

Cabling and Technology

Information

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).

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

The following information applies to installations in which multimode fiberoptic cables are connected to a Gigabit-LX port or a 10-Gigabit LRM 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 or 10-Gigabit LRM 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 Appendix B, 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.

For 10-Gigabit LRM using OM3 cable (50 m multimode @ 1500/500 MHz*km), a mode conditioning patch cord is not required. Other multimode cables may require mode conditioning patch cords to achieve the LRM maximum distances.

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 C-1. Example: Connecting a Mode Conditioning Patch Cord for Gigabit-LX

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

Auto-MDIX Feature: The 10/100/1000-T ports support the IEEE 802.3ab standard, which includes the “Auto MDI/MDI-X” feature. In the default configuration, “Auto”, the ports on the Switch 2910al all automatically detect the type of port on the connected device and operate as either an MDI or MDIX port, whichever is appropriate. So for any connection, a straight-through 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.

If you connect a Switch 2910al twisted-pair port to another switch or hub, which typically have MDI-X ports, the Switch 2910al 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 2910al 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.

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 C-2 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.

■ 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.

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

Because of the HP 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.

Cable Diagram

Note Pins 1 and 2 on connector “A” must be wired as a twisted pair to pins 1 and 2

on connector “B”. Pins 3 and 6 on connector “A” must be wired as a twisted pair to pins 3 and 6 on connector “B”. Pins 4, 5, 7, and 8 are not used in this application, although they may be wired in the cable.

Crossover Twisted-Pair Cable for 10 Mbps or 100 Mbps Network Connection

The HP Auto-MDIX operation of the 10/100 ports on the switch also allows you to use crossover cables for all network connections, to PCs, servers or other end nodes, or to hubs or other switches.

If any of these ports are given a fixed configuration, for example 100 Mbps/ Full Duplex, the ports operate as MDI-X ports, and crossover cables must be then used for connections to hubs or switches or other MDI-X network devices.
