Console Port
This port connects a console to the access point using a serial cable. This connection is described under “Connect a Console to the Access Point” in
chapter 2, “Installing the Access Point 420”. 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 devices such as a 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 ProCurve Networking 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 the following section for information on supplying power to the access point through its RJ-45 port from a network device, such as a switch, that provides Power over Ethernet (PoE).
Power Connector
The Access Point 420 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's power adapter 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 ProCurve Networking 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.
Note that if the access point is connected to a PoE source device and also connected to a local power source through the AC power adapter, PoE will be disabled.

Installation Procedures
Installation Precautions:
Follow these precautions when installing your Access Point 420:
■
■
■
■
■
■
■
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 connection 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 using its AC power adapter, Power over Ethernet is disabled.
Use only the AC power adapter supplied with the access point. Use of other adapters, including adapters that came with other ProCurve
Networking products, may result in damage to the equipment.
When using the acess point’s AC power adapter, 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 devices near the AC power connectors.
Do not install the access point in an environment where the operating ambient temperature might exceed 40
°
C (104
°
F).
Make sure the air flow around the sides of the access point is not restricted.

Installation Procedures
Port Type
10/100Base-TX
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
Table 2-1.
Summary of Cable Types to Use With the Access Point
Cable Type
Twisted-Pair Cables
• 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.
Length Limits
100 meters
Note: Since the 10Base-T operation is through the 10/100Base-TX port on the access point, if you ever want to upgrade the ports on other devices to 100Base-TX, it would be best to cable the 10/100Base-TX port on the access point initially with category 5 cable.
The 10/100-Base-TX port on the
Access Point 420 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 a straightthrough or crossover cable.
■ Installation Location - Before installing the access point, plan its location 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 performance. 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.
• At 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.

If the 10/100Base-TX link LED does not go on when the network cable is
connected to the port, see “Diag-
nosing with the LEDs” in chapter 5,
Cable:
• Category 3, 4, or 5 for 10 Mbps ports (UTP)
• Category 5 or better for 100 Mbps ports (STP)
Maximum distance: 100 meters
To disconnect:
Press the small tab on the plug and pull the plug out of the port .
6. Position the Antennas on the Access Point
The antennas emit and receive signals along a toroidal plane—and thus provide more effective coverage when positioned along different axes. For example, you might position the antennas around 45 to 90 degrees from each other.
The access point compares the strength of an incoming signal on both antennas, and uses the antenna receiving the stronger signal to communicate with a wireless client. Note that both antennas are used to transmit, but never at the same time.
The access point’s antennas can also be replaced by various external antenna options that offer extended radio range and specific radio coverge patterns.

Out-of-Band: Use a serial cable for connecting a PC or VT-100 terminal to be used as a console directly to the access point.
In-Band: Access the console using Telnet or Secure Shell (SSH) from a
PC on the network, and a VT-100 terminal emulator. This method requires that you first configure the access point with an IP address and subnet mask by using either out-of-band console access or through DHCP. For more information on IP addressing and on starting a Telnet or SSH session,
see chapter 3, “Getting Started With Access Point Configuration”, and the
Management and Configuration Guide, which is on the Documentation
CD-ROM that came with your access point.
The Access Point 420 can simultaneously support one out-of-band console session through the Console Port and four in-band Telnet or SSH console sessions.
For information on using the Web browser interface to configure the access point, refer to the Management and Configuration Guide .
Terminal Configuration
To connect a console to the access point, 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:
• 9600 baud
• 8 data bits, 1 stop bit, no parity, and flow control set to None
• For the Windows Terminal program, also disable (uncheck) the “Use

The Access Point 420 is designed to provide access to a wired LAN for wireless clients. An integrated wired/wireless LAN is called an Infrastructure configuration. 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, 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.

Wireless Client
The Basic Service Set (BSS) defines the communications domain for each access point and its associated wireless clients. The BSS ID is a 48-bit binary number based on the access point’s wireless MAC address, and is set automatically and transparently as clients associate with the access point. The BSS ID is used in frames sent between the access point and its clients to identify traffic in the service area.
The BSS ID is only set by the access point, never by its clients. The clients only need to set the Service Set Identifier (SSID) that identifies the service set provided by one or more access points. The SSID can be manually configured by the clients, can be detected in an access point’s beacon, or can be obtained by querying for the identity of the nearest access point. For clients that do not need to roam, set the SSID for the wireless card to that used by the access point to which you want to connect.
Installing the Access Point 420
Sample Network Topologies
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 wireless network cards, adapters, and access points within a specific ESS must be configured with the same SSID.

Getting Started With Access Point
Configuration
C a u t i o n
This chapter is a guide for using the access point’s console to quickly assign an Internet Protocol (IP) 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 Web browser interface, 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 is configured as a DHCP client. If the access point fails to obtain an IP address from the DHCP server, its IP address defaults to 192.168.1.1. If this address is not compatible with your network, then the access point can only be managed 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 to the console and web browser interface. Other parameters can be left at their default settings or you can configure them with values you enter.
The country code for the ProCurve Wireless Access Point 420 NA (J8130B) sold in the United States and Canada is fixed in the firmware and cannot be changed. This means that only radio channels 1-11 are available for this model.
The country code for the ProCurve Wireless Access Point 420 WW (J8131B) sold in other countries is not set, and must be configured before you can enable radio communications for the access point. Setting the country code enables only those radio channels permitted for wireless networks in the
Note that once you have set the country code, it can only be changed by
restoring the factory default settings as described under “Restoring the
Factory Default Configuration” on page 5-8.
3-1
Getting Started With Access Point Configuration
N o t e
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 or Secure Shell (SSH) session, or through the access point’s Web browser interface.
For more information on IP addressing, refer to “Configuring IP Settings” in the Management and Configuration Guide .
By default, the access point is configured to acquire an IP address configuration from a DHCP server. To use DHCP instead of the manual method described in this chapter, see “Configuring IP Settings” 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).
To Set the Manager User Name and Password
Management access to the access point’s Web and CLI interface is controlled through user names and passwords. A Manager user name and password allows full read/write privileges for the Web and CLI. An Operator user name and password can also be configured. The Operator is restricted to read-only access. A maximum of only two users can be configured, one Manager and one Operator.
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.
Type admin for the default Manager 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.

To Configure Radio Settings
The access point supports up to eight Service Set IDentifier (SSID) interfaces.
Most radio parameters apply globally to all configured SSID interfaces. For each SSID interface, different security settings, VLAN assignments, and other parameters can be applied.
One SSID interface on the access point is set as the primary. The primary SSID is the only SSID broadcast in the access point’s beacon frames. Other created
SSID interfaces are set as secondary. Secondary SSIDs are all “hidden,” only being advertised in probe responses.
The radio is disabled if the Country Code is not set. Once the Country Code is set,the radio can be enabled.

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 or a Secure Shell client, or a Web browser interface. The above procedure also configured the primary Service Set Identifier (SSID), the 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. Note that some wireless clients can be configured to scan all of the radio channels for an access point and the SSID.
Some basic information on managing your access point is included in the next section. For more information on the console and Web browser interfaces, and all the features that can be configured on the Access Point 420, 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 console session because of a lost manager password, you can clear the password and user name by getting physical access to the access point and pressing and holding the Reset button for more than five seconds. However, note that this action resets all configuration settings to the factory defaults.
The Reset button is provided for your convenience, but if you are concerned with the security of the access point configuration and operation, you can disable it. For more information, see the Management and Configuration

P r o f e s s i o n a l
I n s t a l l a t i o n
R e q u i r e d
Only the ProCurve Networking antennas listed in this guide are permitted to be connected to the Access Point 420. You must use the appropriate antennas and cables for your given region. You are responsible for verifying local regulations or legislation that may impose restrictions on the use of specific antenna and cable combinations. For this reason, ProCurve Networking recommends that you consult with a professional installer who is trained in
RF installation and knowledgeable in the local regulations prior to connecting an external antenna to your wireless radio product. It is the responsibility of the end user to ensure that the antenna installation complies with the local radio regulations.

Using an External Antenna with the Access Point 420
Installation Procedures
Installation Procedures
Follow these steps to install an external antenna and connect it to the
Access Point 420.
Never mount the access point outdoors to be near an external antenna. The access point must always be installed indoors.
1. Plan the Installation
■
■
Pigtail Cables - Use the coax pigtail cable attached to the antenna to connect to the access point. Because most pigtail cables are a relatively short length (83 cm or 33 inches), be sure to find a suitable mounting position for the antenna that is not too far from the access point. If an extension cable is required, please contact a professional installer who is trained in RF installation and knowledgeable in the local regulations.
Installation Location - Plan the antenna’s position and orientation.
The radiated output power of this device is below the FCC radio exposure limits. Nevertheless, the device should be used in such a manner that the potential for human contact during normal operation is minimized. To avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antennas should not be less than 20 cm (8 inches) during normal operation.
■
Consider these points:
• Use the antenna’s mounting bracket or other hardware, if included.
• For optimum performance, mount antennas as high as possible above any obstructions, and away from any signal absorbing or reflecting structures (such as those containing metal)
• Be sure there are no other radio antennas mounted within 2 m (6 ft).
• Consider the antenna’s radio coverage pattern so that it can properly cover the intended service area.
Omnidirectional Antennas - Consider these factors when selecting a location for these antennas:
• Always mount the antenna in a vertical orientation so that the radio coverage pattern fills the intended horizontal space.
4-3
Using an External Antenna with the Access Point 420
Installation Procedures
■
■
• For optimum coverage, mount the antenna at the center of the area with a line-of-sight path to all points within the area.
• Avoid mounting next to or near building support columns or other obstructions that may cause reduced signal or null zones in parts of the coverage area.
• When mounting outdoors using a mast, make sure that the antenna extends beyond the top of the mast.
Directional Antennas - Consider these factors when selecting a location for these antennas:
• For optimum coverage, mount the antenna above any obstructions, directed at the center of the coverage area sector.
• High-gain directional antennas provide a flattened radio coverage pattern in the horizontal plane. Use the tilting or articulated mounts to point the antennas towards the coverage area.
Outdoor Installation - When installing an antenna outdoors, be sure to consider these additional factors:
• Always place the antenna away from power and telephone lines
• Make sure that the antenna, any supporting structure, and cables are all properly grounded.
• For lightning protection, consider using a lightning arrestor immediately before the cable enters the building.
W a r n i n g Never install an antenna or construct a radio mast near overhead power lines.
2. Mount the Antenna
Install the antenna in its planned location using the brackets, clips, or other hardware included in the antenna package.
Refer to documentation included with the antenna for specific information and installation instructions.
3. Connect Pigtail Cables to the Access Point
Use the pigtail cables that are attached to the antenna, or are included in the antenna package. If an extension cable is required, please contact a professional installer who is trained in RF installation and knowledgeable in the local regulations.
4-4
Using an External Antenna with the Access Point 420
Installation Procedures
Note that diversity antennas have two pigtail cables. A diversity antenna includes two internal antenna elements that are identical. Both antenna pigtail cables must be connected to the access point for correct operation.
Other non-diversity antennas, which have only one pigtail cable, attach to the access point’s right antenna connector. The access point’s right antenna is the one on the side closest to the LED indicators. When using a non-diversity antenna, a 50-ohm terminator (included with the antenna) must be connected to the access point’s left antenna connector.
To connect pigtail cables to the access point, follow these steps:
1.
Disable the access point radio using the web browser interface, CLI, or
SNMP.
2.
Remove power to the access point.
3.
Remove both of the access point’s antennas by unscrewing them at their base.

Unscrew antenna to remove
4.
For diversity antennas, connect the antenna pigtail cables to the exposed
Reverse SMA connectors on both sides of the access point.
For non-diversity antennas, be sure to connect the single pigtail cable to the Reverse SMA connector on the access point’s right side. When using a non-diversity antenna, you must also connect the 50-ohm terminator
(5092-0933), included with the antenna, to the access point’s left-side
Reverse SMA connector.

5.
Reconnect power to the access point.
Before enabling the radio with an external antenna attached, be sure to first configure the access point’s antenna mode and transmit power settings.
4. Configure the Antenna Mode and Transmit Power
Control Limits
Using the Web browser interface, CLI, or SNMP, you must configure the
Access Point 420 to use an external antenna. For more information on access point configuration, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point.
The access point must be set for the type of external antenna that is attached, either a diversity antenna that connects to both access point antenna connectors, or non-diversity antenna that has a single pigtail connection.
The access point’s transmit power must be limited to conform to local regulations. Use the regional settings for each antenna and radio mode as provided in the Transmit Power Control tables below.
An improper combination of transmit power and antenna gain may result in an EIRP power level in excess of the legally imposed limit. The transmit power reduction required for each antenna in each radio mode is listed in the following tables. Failure to adhere to these guidelines may violate the radio

Troubleshooting
This chapter describes how to troubleshoot your ProCurve Wireless
Access Point 420. Note that this document describes troubleshooting mostly from a hardware perspective. You can perform more in-depth troubleshooting on the Access Point 420 using the software tools available with the access point, including the full-featured console interface and the built-in Web browser interface.

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.
By default, 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 communication mode.
• 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.
5-1
Troubleshooting
Basic Troubleshooting Tips
■
■
■
■
Because the Access Point 420 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.
All devices connected to the Access Point 420 should be configured to auto-negotiate. To correct this problem you have to manually set the access point’s RJ-45 port to match the duplex mode used by the attached device.
Faulty or loose cables.
Look for loose or obviously faulty connections.
If the cables appear to be OK, make sure the connections are secure. 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 ProCurve Networking Web site, http:// www.procurve.com
. under “network configuration examples.”
Mobile users cannot connect to the network.
Make sure that the access point and wireless clients are configured with compatible security settings. 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 ProCurve Networking
Web site, http://www.procurve.com
, in the Reference Library section under http://www.hp.com/rnd/library/index.htm

Problem
The access point is not plugged into an active AC power source, or the access point’s AC power adapter may have failed.
Diagnostic Tips:
Solution
1. Verify that the power cord is plugged into an active power source and to the access point's AC power adapter. Make sure these connections are secure.
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 point’s
AC power adapter may have failed. Call your HP-authorized network reseller, or use the electronic support services from HP to get assistance. See the Customer Support/
Warranty booklet for more information.

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-TX network connection is not working properly.
The port may be improperly configured.
Solution
1. Verify that access point’s 10/100Base-TX 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 identifying the error condition. You can view the console log at that point using the Web browser interface. Select the Status tab, then Events Log, or view the entry file on your Syslog server if one is configured.
If necessary to resolve the problem, contact your HP-authorized network reseller, 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 an 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. Also verify that the country code has been set.
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.
• Verify duplex operation (see page 5-1).
• If these procedures don’t resolve the problem, try using a different cable.
VLAN configuration may affect the port operation. Use the access point’s console to see how the port is configured for VLANs.
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.

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 troubleshoot:
■ 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.
The Status tab can be used to display access point configuration settings, attached client station settings, and the event log.
■ 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 point’s console port. (For information on the console port’s pin
assignments, see “Direct Console Access” on page 2-12.) The console
interface is also accessible through a Telnet or Secure Shell connection.

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 access point for just a second.
If you are attached to the console port, you will see that the access point starts the power-on self test.
If you hold the reset button down for 5-10 seconds, you reset the board and
reload the factory default settings. See “Restoring the Factory Default Configuration” on page 5-8.
Power-cycling the access point and pressing the Reset button both cause the access point to perform its power-on self test, which normally resolves 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. Also, event log messages are erased, and the IP address may be changed if you are using DHCP.
Checking the Access Point’s 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 5-3 for information on interpreting

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 point’s Console Port and
configure it with the terminal communication settings shown on page 2-11.
5-6
Troubleshooting
Hardware Diagnostic Tests
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 Web browser or a Syslog server.
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 420 must be compatible with the appropriate 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.
■ 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 point’s console interface from a terminal connected to the access point or through a Telnet or Secure
Shell connection. For more information, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your 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. You can run a Ping test to verify that the entire communication path between the two network devices is functioning correctly.

Troubleshooting
Restoring the Factory Default Configuration
N o t e
N o t e
Restoring the Factory Default
Configuration
As part of your troubleshooting process on the Access Point 420, it may become necessary to return the access point’s configuration to the factory default settings. This process momentarily interrupts the access point’s operation, 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 addresses, 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 information 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 from the access point itself, or through the access point console.
The Reset button and console port can be disabled by the access point’s software. However, the Reset button and console port cannot be disabled at the same time. When the Reset button is disabled, it is not possible to disable the serial port. For more information, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point.
5-8
Troubleshooting
Restoring the Factory Default Configuration
To execute the factory default reset on the access point, perform these steps:
1.
Using a pointed object, press and hold the Reset button on the back of the access point for 5-10 seconds. On the console display, the cursor will move down to the next line, indicating that the factory defaults have been reloaded.
2.
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 reset configuration command from the console command prompt.

Access Point Port and Network Cables
N o t e
This appendix includes access point connector information and network cable information for cables that should be used with the Access Point 420, including minimum pin-out information and specifications for twisted-pair cables.
Incorrectly wired cabling is the most common cause of problems for LAN communications. ProCurve Networking 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
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 “straightthrough” twisted-pair cable to connect this port to most network interconnection devices such as a switch or a 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 ProCurve Networking 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 standard.
To provide Power over Ethernet to the access point, all 4 pairs must be connected for any network cable attached to this port; the cable must meet ISO/DIS 11801 Class D requirements and IEEE 802.3af requirements.
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 “straightthrough” or “crossover” cable.
