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 Port The 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 points network port from a network device, such as a switch, that provides Power over Ethernet (PoE). Power Connector The 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. C a u t i o n 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. 1-6 I n t r o d u c i n g t h e h p p r o c u r v e w i r e l e s s A P 4 2 0 w w

Once the access point is mounted, plug it into the nearby main power source, or into a switch that provides Power over Ethernet. 5. Connect to the network (page 2-10). Using the appropriate network cable, connect the access point to a network connection point, such as a switch. 6. Position the antennas on the access point (page 2-10). Position each antenna along a different axis to enhance signal coverage. 7. Connect a console to the access point (optionalpage 2-11). You may wish to modify the access points 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 access points console port. At this point, your access point is fully installed. See the rest of this chapter if you need more detailed information on any of these installation steps. 2-2 C a u t i o n s Installing the wireless AP 420 ww/na Installation Procedures Installation Precautions:

Follow these precautions when installing your HP Access Point 420ww/na. 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 55C (131F). Make sure the air flow around the sides of the access point is not restricted. 2-3 I n s t a l l i n g t h e w i r e l e s s A P 4 2 0 w w

n a Installing the wireless AP 420 ww/na Installation Procedures 1. 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 Port Type Cable Type Length Limits 10/100Base-TX 10 Mbps operation:

100 meters Twisted-Pair Cables 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. Note: 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. 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 points 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. a n

n a Connect network cable to PoE switch Or connect power adapter to the power connector Note The AP 420 ww/na does not have a power switch. It is powered on when the power adapter is connected to the access point and to a power source, or when a network cable is connected to the access point and to a network device that provides Power over Ethernet. For safety, when connecting to an elec-

trical outlet, the power outlet should be located near the access point. 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. 2-5 Installing the wireless AP 420 ww/na Installation Procedures 2. Check the LEDs on the access point as described below. Power LED Ethernet LED Wireless LED When the access point is powered on, it performs its diagnostic self test. The self test takes approximately 50 seconds to complete

. LED Behavior:

During the self test:

The 10/100BASE-T and Wireless LEDs go off and then may come on again during phases of the self test. For the duration of the self test, the Power LED blinks. When the self test completes successfully:

The Power LED remains on. The 10/100BASE-T and Wireless LEDs on the top of the access point go into their normal operational mode:

If the ports are connected to active network devices, 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 Power LED does not stop blinking, the self test has not completed correctly. Refer to chapter 4, Troubleshooting for diagnostic help. a n

n a 5. Connect the Access Point to a Power Source 1. Plug the included power adapter into the access points power connector and into a nearby AC power source. Or, alternatively, connect the Ethernet port on the access point to a switch or other network device that provides Power over Ethernet. 2. Re-check the LEDs during self test. See LED Behavior on page 2-6. 2-9 Installing the wireless AP 420 ww/na Installation Procedures 6. Connect the Network Cable Connect the network cable, described under Cabling Infrastructure

(page 2-4), from the network device or your patch panel to the RJ-45 port on the access point. 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 access point and for the connected device, the 10/100BASE-T link LED should light to confirm a powered-on device (for example, an end node) is at the other end of the cable. If the 10/100BASE-T link LED does not go on when the network cable is connected to the port, see Diag-

nosing with the LEDs in chapter 4, Troubleshooting. RJ-45 connector Unshielded twisted-pair cable:

Category 3, 4, or 5 for 10 Mbps ports

Category 5 or better for 100 Mbps ports Maximum distance: 100 meters To disconnect:

Press the small tab on the plug and pull the plug out of the jack. 7. Position the Antennas on the Access Point The antennas emit signals along a toroidal plane and thus provide more effective coverage when positioned along alternate axes. For example, you might position the antennas around 45 to 90 degrees from each other. The access point also compares the strength of an incoming signal on both antennas, and uses the antenna receiving the stronger signal to communicate with a wireless client. a n

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. w 2-14 Infrastructure Wireless LAN for Roaming Wireless PCs Installing the wireless AP 420 ww/na Sample Network Topologies File Server Seamless Roaming Desktop PC Switch Wireless Client w I n s t a l l i n g t h e i r e l e s s A P 4 2 0 w w

Wireless Client The Basic Service Set (BSS) is the communications domain for each access point and its associated wireless clients. For wireless PCs that do not need to support roaming, set the Service Set Identifier (SSID) for the wireless card to the BSS ID of the access point to which you want to connect. Check with your administrator for the BSS ID of the access point to which you should connect. A wireless infrastructure can also support roaming for mobile workers. More than one access point can be configured to create an Extended Service Set (ESS). By placing the access points so that a continuous coverage area is created, wireless users within this ESS can roam freely. All HP wireless network cards and adapters and access points within a specific ESS must be configured with the same SSID. 2-15 Installing the wireless AP 420 ww/na Sample Network Topologies a n

w w 0 2 4 P A s s e l e r i e h t g n i l l a t s n I w 2-16 Getting Started With Access Point Configuration 3 This chapter is a guide for using the access points 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 points 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 Configuration In 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 points console interface, to optimize the access points 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 points 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. 3-1 P o i n t C o n f i g u r a t i o n G e t t i n g S t a r t e d W i t h A c c e s s Getting Started With Access Point Configuration 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 Interface The 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 points model number. Username: admin Password:

Default Gateway 0.0.0.0 SSID ANY Channel 0 (AUTO) IP address of the next-hop gateway node for network traffic that needs to be able to reach off-subnet destinations. The Service Set Identifier is a unique name identifying the communications domain for the access point. Clients that want to connect to the wireless network via this specific access point must set their SSIDs to the same name. 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. 3-5 P o i n t C o n f i g u r a t i o n G e t t i n g S t a r t e d W i t h A c c e s s Getting Started With Access Point Configuration Where to Go From Here The 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. s s e c c A h t i W d e t r a t S g n i t t e G n o i t a r u g i f n o C t n i o P 3-6 Getting Started With Access Point Configuration Using the IP Address for Remote Access Point Management Using the IP Address for Remote Access Point Management With your Access Point 420ww/na, you can use the access points 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 Session To 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 points 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 points 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 points console command (CLI) prompt, for example:

Username: admin Password:

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 Session Your 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 points 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 points onboard software. 3-7 P o i n t C o n f i g u r a t i o n G e t t i n g S t a r t e d W i t h A c c e s s Getting Started With Access Point Configuration Using the IP Address for Remote Access Point Management A typical web browser interface screen is shown in the next illustration. For more information on using the web browser interface, please see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point. An extensive help system is also available for the web browser interface. 3-8 s s e c c A h t i W d e t r a t S g n i t t e G n o i t a r u g i f n o C t n i o P Troubleshooting 4 This 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 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 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. T r o u b l e s h o o t i n g 4-1 Troubleshooting Basic Troubleshooting Tips g n i t o o h s e l b u o r T 4-2

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. Troubleshooting Diagnosing with the LEDs Diagnosing with the LEDs Table 4-1 shows LED patterns on the access point that indicate problem conditions. 1. Check in the table for the LED pattern that you see on your access point. 2. Refer to the corresponding diagnostic tip on the next few pages. Table 4-1.

Tip 1 Problem The access point is not plugged into an active AC power source, or the access points power supply may have failed. Solution 1. Verify that the power cord is plugged into an active power source and to the access point. Make sure these connections are snug. 2. Try power cycling the access point 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 access point into a different outlet or try a different power cord. If the power source and power cord are OK and this condition persists, the access points 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. T r o u b l e s h o o t i n g 4-3 Solution 1. Verify that access points 10/100Base-T port is attached to a PoE source device. 2. Verify that the PoE source device is powered on, and that the PoE function has been administratively enabled on the source port attached to the access point. 3. Refer to Tip 6 to verify that the network cable is functioning properly. 1. Try resetting the access point by pressing the Reset button on the back of the access point, or by power cycling the access point. 2. If the fault indication reoccurs, attach a console to the access point (as indicated in chapter 2). Then, reset the access point. 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 using the show logging commands. 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. Verify that the wireless port has not been disabled through a access point configuration change. You can use the console interface, or, if you have configured an IP address on the access point, use the web browser interface to determine the state of the wireless port and re-enable the port if necessary. Try the following procedures:

Verify that both ends of the cabling, at the access point and the connected device, are connected properly.

Verify the connected device and access point are both powered on and operating correctly. If the other procedures dont resolve the problem, try using a different cable.

VLAN configuration may affect the port operation. Use the access points console to see how the port is configured for VLANs. For software troubleshooting tips, see the chapter Troubleshooting in the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point. Make sure also, that the device at the other end of the connection is indicating a good link to the access point. If it is not, the problem may be with the cabling between the devices or the connectors on the cable. Troubleshooting Diagnosing with the LEDs Tip 2 3 4 5 6 Problem The access point is not receiving power from the PoE source. The access point has experienced a software failure during self test. Wireless link has been administratively disabled. The 10/100Base-T network connection is not working properly. The port may be improperly configured. g n i t o o h s e l b u o r T 4-4 Troubleshooting Proactive Networking Proactive Networking The following interfaces provide tests, indicators, and an event log that can be used to monitor the access point 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 access point from a PC running a supported web browser, for example Microsoft Internet Explorer. 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 access points console port. The cable to make that connection is provided with your access point. The console interface is also accessible through a Telnet connection. For more information on using these software tools to diagnose and manage your access point, see the Troubleshooting chapter in the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point. T r o u b l e s h o o t i n g 4-5 Hardware Diagnostic Tests Testing the Access Point by Resetting It If you believe that the access point is not operating correctly, you can reset the access point to test its circuitry and operating code. To reset an access point, either Unplug and plug in the power cord (power cycling) Press the Reset button on the back of the switch Power 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 Points LEDs The 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 Messages Useful 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 points 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 points event log, which can be accessed from the console using the show logging commands. Troubleshooting Hardware Diagnostic Tests g n i t o o h s e l b u o r T 4-6 Troubleshooting Hardware Diagnostic Tests Testing Twisted-Pair Cabling Network 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 Communications You 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 address These tests can be performed through the access points 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 Communications Both 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. 4-7 T r o u b l e s h o o t i n g Troubleshooting Restoring the Factory Default Configuration Restoring the Factory Default Configuration As part of your troubleshooting process on the Access Point 420wl, it may become necessary to return the access points configuration to the factory default settings. This process momentarily interrupts the access points 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. 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.

N o t e Incorrectly wired cabling is the most common cause of problems for LAN communications. HP recommends that you work with a qualified LAN cable installer for assistance with your cabling requirements. Access Point Ports The 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 Cables 10 Mbps Operation Category 3, 4, or 5 100-ohm unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable, complying with IEEE 802.3 Type 10Base-T specifications, fitted with RJ-45 connectors 100 Mbps Operation Category 5 100-ohm UTP or STP cable, complying with IEEE 802.3u 100Base-TX specifications, fitted with RJ-45 connectors B-1 N e t w o r k C a b l e s A c c e s s P o i n t P o r t a n d d n a t r o P t n i o P s s e c c A s e l b a C k r o w t e N Access Point Port and Network Cables Twisted-Pair Cable/Connector Pin-Outs Twisted-Pair Cable/Connector Pin-Outs The 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. B-2 Access Point Port and Network Cables Twisted-Pair Cable/Connector Pin-Outs Straight-Through Twisted-Pair Cable for 10 Mbps or 100 Mbps Network Connections Because the 10/100 port on the access point uses an MDI pin configuration, you must use straight-through cable for network connections to hubs or switches that only have MDI-X ports. However, if the device to which you are connecting supports auto-MDIX operation, you can use either straight-

through or crossover cable. Cable Diagram N o t e
