This connection is described under “Connect a Console to the Access Point” in chapter 2, “Installing the Access Point 420wl”. The console can be a PC or workstation running a VT-100 terminal emulator, or a VT-100 terminal.Network PortThe access point includes one 10/100Base-TX port. This port uses MDI (i.e., internal straight-through) pin configuration. You can therefore use straight-through twisted-pair cable to connect this port to most network interconnection device such as switch or router that provide MDI-X ports. However, if you need to connect the access point to a workstation or other device that only has MDI ports, then use crossover twisted-pair cable.Ports on most HP switches have the “HP Auto MDIX” feature, which means that you can use either straight-through or crossover twisted-pair cables to connect the access point to these switches.Refer to following section for information on supplying power to the access point’s network port from a network device, such as a switch, that provides Power over Ethernet (PoE).Power ConnectorThe AP 420 ww/na does not have a power switch; it is powered on when connected to the AC power adapter, and the power adapter is connected to an active AC power source. The access point automatically adjusts to any voltage between 100--240 volts and either 50 or 60 Hz. There are no voltage range settings required.Caution Use only the AC power adapter supplied with the access point. Use of other adapters, including adapters that came with other HP network products, may result in damage to the equipment.The access point may also receive Power over Ethernet (PoE) from a switch or other network device that supplies power over the network cable based on the IEEE 802.3af standard.

2-3Installing the wireless AP 420 ww/naInstallation ProceduresInstalling the wireless AP 420 ww/naInstallation Precautions:Follow these precautions when installing your HP Access Point 420ww/na.Cautions ■Make sure that the power source circuits are properly grounded, then use the power adapter supplied with the access point to connect it to the power source. ■You can alternatively power the access point through a network connec-tion to a switch or other network connection device that provides Power over Ethernet. However, note that if the access point is connected to a power source, Power over Ethernet will be disabled.■Use only the AC power adapter supplied with the access point. Use of other adapters, including adapters that came with other HP network products, may result in damage to the equipment.■When installing the access point, note that the AC outlet should be near the access point and should be easily accessible in case the access point must be powered off.■Ensure that the access point 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 access point 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 access point in an environment where the operating ambient temperature might exceed 55°C (131°F).■Make sure the air flow around the sides of the access point is not restricted.
2-4Installing the wireless AP 420 ww/naInstallation ProceduresInstalling the wireless AP 420 ww/na1. Prepare the Installation Site■Cabling Infrastructure - Ensure that the cabling infrastructure meets the necessary network specifications. See the following table for cable types and lengths, and see appendix B, “Access Point Port and Network Cables” for more information:Table 2-1. Summary of Cable Types to Use With the Access Point■Installation Location - Before installing the access point, plan its loca-tion and orientation relative to other devices and equipment:• Try to place the access point in the center of your wireless network. Normally, the higher you place the antenna, the better the perfor-mance. You may need to reposition the access point after testing the signal strength on several wireless clients to ensure that the access point’s location provides optimal reception throughout your office.• In the back of the access point, leave at least 7.6 cm (3 inches) of space for the twisted-pair cabling and the power cord.• On the sides of the access point, leave at least 7.6 cm (3 inches) for cooling.Port Type Cable Type Length LimitsTwisted-Pair Cables10/100Base-TX • 10 Mbps operation:Category 3, 4, or 5, 100-ohm unshielded twisted-pair (UTP)• 100 Mbps operation:Category 5, 100-ohm UTP or shielded twisted-pair (STP) cable.100 metersNote: Since the 10Base-T operation is through 10/100Base-TX ports, if you ever want to upgrade the ports to 100Base-TX, it would be best to cable the ports initially with category 5 cable.The 10/100-Base-TX port on the Access Point 420ww/na uses an MDI pin configuration, which requires you to use straight-through cable when connecting to another device that has an MDI-X port, or crossover cable when connecting to a device that has an MDI port. However, if the device to which you are connecting supports auto-MDIX, then you can use either straight-through or crossover cable.

The wireless solution supports a stand-alone wireless network configuration as well as an integrated configuration with wired Ethernet LANs. Wireless network cards, adapters, and access points can be configured as:■Ad hoc for departmental or SOHO LANs■Infrastructure for wireless LANs■Infrastructure wireless LAN for roaming wireless PCsFor more topology information, see the HP network products World Wide Web site, http://www.hp.com/go/hpprocurve.Ad Hoc Wireless LAN (no access point)An ad-hoc wireless LAN consists of a group of computers, each equipped with a wireless adapter, connected via radio signals as an independent wireless LAN. Computers in a specific ad-hoc wireless LAN must therefore be config-ured to the same radio channel. An ad-hoc wireless LAN can be used for a branch office or SOHO operation.Notebook with Wireless USB AdapterNotebook with Wireless PC CardPC with Wireless PCI Adapter
2-14Installing the wireless AP 420 ww/naSample Network TopologiesInstalling the wireless AP 420 ww/naInfrastructure Wireless LANThe Access Point 420ww/na can provide access to a wired LAN for wireless clients. An integrated wired/wireless LAN is called an Infrastructure configu-ration. A Basic Service Set (BSS) consists of a group of wireless PC users, and an access point that is directly connected to the wired LAN. Each wireless PC in this BSS can talk to any computer in its wireless group via a radio link, or access other computers or network resources in the wired LAN infrastructure via the access point.The infrastructure configuration not only extends the accessibility of wireless PCs to the wired LAN, but also increases the effective wireless transmission range for wireless PCs by passing their signal through one or more access points.A wireless infrastructure can provide an extension of the wired LAN to wireless clients for access to a local resources, or for a bridged connection between mobile workers located at distant points on the network.Desktop PC AP 420 ww/naFileServerSwitchPC with wireless PCI AdapterNotebook with wireless PC Card AdapterWired LAN Extension to Wireless Adapters

3-1Getting Started With Access Point Configuration3Getting Started With Access Point ConfigurationThis chapter is a guide for using the access point’s console to quickly assign an IP (Internet Protocol) address and subnet mask to the access point, set a Manager password, and, optionally, configure other basic features.For more information on using the access point’s console and the other access point management interfaces: the web browser interface and SNMP manage-ment tools, please see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point.Recommended Minimal ConfigurationIn the factory default configuration, the access point 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 access point through in-band (networked) access, you should configure the access point 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 can be left at their default settings or you can configure them with values you enter.Many other features can be configured through the access point’s console interface, to optimize the access point’s performance, to enhance your control of the network traffic, and to improve network security. Once an IP address has been configured on the access point, these features can be accessed more conveniently through a remote Telnet session, through the access point’s web browser interface, and from an SNMP network management station running a network management program. For a listing of access point features avail-able with and without an IP address, refer to “How IP Addressing Affects Access Point Operation” in the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point.For more information on IP addressing, refer to “IP Configuration” in the Management and Configuration Guide.
3-2Getting Started With Access Point ConfigurationGetting Started With Access Point ConfigurationNote By default, the access point is configured to acquire an IP address configura-tion from a DHCP server. To use DHCP instead of the manual method described in this chapter, see “DHCP Operation” in the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point.Using the Command Line InterfaceThe quickest and easiest way to minimally configure the access point for management and password protection in your network is to use a direct console connection to the access point, start a console session, and access the command line interface (CLI).1. Using the method described in the preceding chapter, connect a terminal device to the access point, and press [Enter] to initiate the console connection.2. Enter “admin” for the user name. The default password is null, so just press [Enter] at the password prompt. The CLI prompt appears displaying the access point’s model number.3. Type configure to enter global configuration mode.4. Type username username to create a user name for the Manager, where “username” can consist of 3 to 16 alphanumeric characters and is case sensitive.5. Type password password to create a password for the Manager, where “password” can consist of up to 8 alphanumeric characters and is case sensitive.Username: adminPassword:HP Procurve Access Point wl420#HP Procurve Access Point wl420#configureEnter configuration commands, one per line.

Clients that want to connect to the wireless network via this specific access point must set their SSIDs to the same name. Channel 0 (AUTO) The radio channel through which the access point communicates with its wireless clients. For most wireless clients, the radio channel is automatically set to the same as that used by the access point to which it is linked. Wireless Operation Disabled Wireless operation should be enabled only after you configure the appropriate SSID and radio channel using the no shutdown command.Note: The IP address and subnet mask assigned for the access point must be compatible with the IP addressing used in your network. For more information on IP addressing, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point.
3-6Getting Started With Access Point ConfigurationGetting Started With Access Point ConfigurationWhere to Go From HereThe above procedure using the CLI configured your access point with a Manager password, IP address, and subnet mask. As a result, with the proper network connections, you can now manage the access point from a PC equipped with Telnet, a web browser interface, or from an SNMP-based network management station. The above procedure also configured the Service Set Identifier (SSID), radio channel, and enabled wireless operation. Your wireless clients can now access the network by setting their SSID and radio channel to the same values used by the access point.Some basic information on managing your access point 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 Access Point 420wl, please see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point.To Recover from a Lost Manager Password: If you cannot start a con-sole session because of a lost Manager password, you can clear all passwords and user names by getting physical access to the access point and pressing and holding the Reset button for a full second. However, note that this action will reset all configuration settings to the factory defaults.
3-7Getting Started With Access Point ConfigurationUsing the IP Address for Remote Access Point ManagementGetting Started With Access Point ConfigurationUsing the IP Address for Remote Access Point ManagementWith your Access Point 420ww/na, you can use the access point’s IP address to manage the access point from any PC that is on the same subnet as the access point. You can use either a Telnet session or a standard web browser to manage the access point.Starting a Telnet SessionTo access the access point through a Telnet session, follow these steps:1. Make sure the access point is configured with an IP address and that the access point is reachable from the PC that is running the Telnet session (for example, by using a Ping command to the access point’s IP address).2. Start the Telnet program on a PC that is on the same subnet as the access point and connect to the access point’s IP address.3. Enter the user name and password. (The default user name is “admin” and the default password is null. You will then see the access point’s console command (CLI) prompt, for example:Enter ? to see a list of commands that can be executed at the prompt. Entering any command followed by ? displays a list of options that are available at that point in the command entry.Starting a Web Browser SessionYour AP 420 ww/na can be managed through a graphical interface that you can access from any PC or workstation on the network by running your web browser (e.g., Java-enabled Internet Explorer 5.5) and typing in the access point’s IP address as the URL. (See “Using the Command Line Inter-face” on page 3-2 for information on setting the IP address.) No additional software installation is required to make this interface available; it is included in the access point’s onboard software.Username: adminPassword:HP Procurve Access Point wl420#

4-1Troubleshooting4TroubleshootingThis chapter describes how to troubleshoot your HP Procurve Access Point 420ww/na. Note that this document describes troubleshooting mostly from a hardware perspective. You can perform more in-depth trouble-shooting on the Access Point 420ww/na using the software tools available with the access point, including the full-featured console interface, and the built-in web browser interface, or SNMP-based network management tools. For more information, see the chapter “Troubleshooting” in the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point.This chapter describes the following:■basic troubleshooting tips (page 4-1)■diagnosing with the LEDs (page 4-3)■Proactive Networking tools (page 4-5)■hardware diagnostic tests (page 4-6)■restoring the factory default configuration (page 4-8)■downloading new software to the Access Point 420wl (page 4-9)■HP Customer Support Services (page 4-9)Basic Troubleshooting TipsMost 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 port uses auto-negotiation to determine the duplex mode. That is, when connecting to attached devices, the access point 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 use auto-negotiation, the access point will automatically negotiate both link speed and commu-nication mode.
4-2TroubleshootingBasic Troubleshooting TipsTroubleshooting• If the connected device has a fixed configuration, for example 100 Mbps, at half or full duplex, the access point will automatically sense the link speed, but will default to a communication mode of half duplex.Because the AP 420 ww/na behaves in this way (in compliance with the IEEE 802.3 standard), if a device connected to the access point has a fixed configuration at full duplex, the device will not connect correctly to the access point. The result will be high error rates and very inefficient communications between the access point and the device.Make sure that all devices connected to the AP 420 ww/na are config-ured 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, “Access Point Port and Network Cables” for pinouts and correct cable wiring. A category 5 cable tester is a recommended tool for every 100Base-TX network installation.■Improper Network Topologies. It is important to make sure you have a valid network topology. Common topology faults include excessive cable length and excessive repeater delays between end nodes. If you have network problems after recent changes to the network, change back to the previous topology. If you no longer experience the problems, the new topology is probably at fault. Sample topologies are shown at the end of chapter 2 in this book, and some topology configuration guidelines can be found online at the HP Procurve web site, http://www.hp.com/go/hpprocurve.■Mobile users cannot connect to the network. Make sure that the access point and wireless clients are configured to the same WEP setting, SSID, and authentication algorithm. Check to ensure that the wireless client is within the maximum range supported by the access point. Also verify that the wireless client has been configured with an IP address compatible with the attached network, either manually or via DHCP.For more information on possible network problems and their solutions, refer to the technical note “Troubleshooting LAN Performance and Intermittent Connectivity Problems”, which can be found on the HP Procurve web site, http://www.hp.com/go/hpprocurve, in the Information Library section.

To reset an access point, either■Unplug and plug in the power cord (power cycling)■Press the Reset button on the back of the switchPower cycling the access point and pressing the Reset button both cause the access point 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 Access Point’s LEDsThe self test passes if the Power LED on the front of the access point stops blinking after approximately 50 seconds. If this LED continues blinking longer than 60 seconds or goes off, there may be a problem with the access point.See “Diagnosing with the LEDs” on page 4-3 for information on interpreting the LED patterns.Checking Console MessagesUseful diagnostic messages may be displayed on the console screen when the access point is reset. As described in chapter 2 under step 7, “Connect a console to the access point”, connect a PC running a VT-100 terminal emulator program or a standard VT-100 terminal to the access point’s Console Port and configure it to run at 9600 baud, and with the other terminal communication settings shown on page 2-11. Then, when you reset the access point, note the messages that are displayed. Additionally, you can check the access point’s event log, which can be accessed from the console using the show logging commands.
4-7TroubleshootingHardware Diagnostic TestsTroubleshootingTesting Twisted-Pair CablingNetwork cables that fail to provide a link or provide an unreliable link between the access point and the connected network device may not be compatible with the IEEE 802.3 Type 10Base-T, or 100Base-TX standards. The twisted-pair cables attached to the Access Point 420wl must be compatible with the appro-priate standards. To verify that your cable is compatible with these standards, use a qualified cable test device.Testing Access Point-to-Device Network CommunicationsYou can perform the following communication tests to verify that the network is operating correctly between the access point 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 addressThese tests can be performed through the access point’s console interface from a terminal connected to the access point or through a Telnet connection. For more information, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point.These tests can also be performed from an SNMP network management station running a program that can manage the access point.Testing End-to-End Network CommunicationsBoth the access point 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 access point. For example, if you have two PCs on the network between which you can run a Ping test through the access point, you can use this test to verify that the entire communication path between the two PCs is functioning correctly.
4-8TroubleshootingRestoring the Factory Default ConfigurationTroubleshootingRestoring the Factory Default ConfigurationAs part of your troubleshooting process on the Access Point 420wl, it may become necessary to return the access point’s configuration to the factory default settings. This process momentarily interrupts the access point’s oper-ation, clears any passwords, clears the console event log, resets the network counters to zero, performs a complete self test, and reboots the access point into its factory default configuration including deleting the IP address, if one is configured.Note This process removes all access point configuration changes that you have made from the factory default settings. This includes, for example, IP address, and radio interface settings. Returning the configuration of these features to their factory default settings may result in network connectivity issues.If the access point has a valid configuration, and you are restoring the factory default settings for a reason other than configuration problems, you should save the access point 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 access point. For both the save and restore processes, you can use the console copy command. For more informa-tion on this command, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point.You can restore the factory default configuration either on the access point itself, or through the access point console.To execute the factory default reset on the access point, perform these steps:1. Using a pointed object, press the Reset buttons on the back of the access point.2. When the Power LED begins to blink, release the Reset button.The access point 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 delete config command from the console command prompt.

HP recommends that you work with a qualified LAN cable installer for assistance with your cabling requirements.Access Point PortsThe fixed RJ-45 10/100Base-TX port on the access point accepts 100-ohm unshielded and shielded twisted-pair cable with RJ-45 connectors as described on the next page.Twisted-Pair Cables10 Mbps Operation Category 3, 4, or 5 100-ohm unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable, complying with IEEE 802.3 Type 10Base-T specifications, fitted with RJ-45 connectors100 Mbps Operation Category 5 100-ohm UTP or STP cable, complying with IEEE 802.3u 100Base-TX specifications, fitted with RJ-45 connectors
B-2Access Point Port and Network CablesTwisted-Pair Cable/Connector Pin-OutsAccess Point Port and Network CablesTwisted-Pair Cable/Connector Pin-OutsThe access point includes one 10/100Base-TX port. This port uses MDI (i.e., internal straight-through) pin configuration. You can therefore use “straight-through” twisted-pair cable to connect this port to most network interconnec-tion device such as switch or router that provide MDI-X ports. However, if you need to connect the access point to a workstation or other device that only has MDI ports, then use “crossover” twisted-pair cable.Ports on most HP switches have the “HP Auto MDIX” feature, which means that you can use either straight-through or crossover twisted-pair cables to connect the access point to the switch.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 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 stan-dard.■To provide Power over Ethernet to the access point, all 4 pairs must be connected for any network cable attached to this port.
