3 Getting Started With Access Point Configuration This 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.
Getting Started With Access Point Configuration Note 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 “DHCP Operation” in the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point.
Getting Started With Access Point Configuration 6. Type end to exit configuration mode, and then enter the show interface ethernet command to display the access point’s default IP configuration, including IP address, subnet mask, and default gateway. The following illustration shows the default settings. HP Procurve Access Point wl420#show interface ethernet Ethernet Interface Information ======================================== IP Address : 0.0.0.0 Subnet Mask : 255.255.255.0 Default Gateway : 0.0.0.
Getting Started With Access Point Configuration 9. Type exit to leave configuration mode, then enter the show interface wireless g command to display the access point’s default wireless configuration, including wireless communication domain, radio channel, and operation status. The following illustration shows the default settings.
Getting Started With Access Point Configuration 12. Set 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. Type channel number, where “number” can be from 1 to 11, depending on the wireless regulations specified by your country. HP Procurve Access Point wl420(if-wireless g)#channel 9 HP Procurve Access Point wl420(if-wireless g)# 13.
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.
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 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.
Getting Started With Access Point Configuration Using the IP Address for Remote Access Point Management Getting Started With Access Point Configuration 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.
4 Troubleshooting 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 troubleshooting 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.
Troubleshooting Basic Troubleshooting Tips • 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.
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.
Troubleshooting Diagnosing with the LEDs Problem Solution 2 The access point is not receiving power from the PoE source. 1. Verify that access point’s 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.
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.
Troubleshooting Hardware Diagnostic Tests 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.
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 appropriate standards. To verify that your cable is compatible with these standards, use a qualified cable test device.
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 point’s configuration to the factory default settings.
Troubleshooting Downloading New Access Point Software Downloading New Access Point Software When product enhancements occur for the AP 420 ww/na, new software can be downloaded to the access point through several methods, for product enhancements and new features. For more information, see the Management and Configuration Guide, which is on the Documentation CD-ROM that came with your access point. The new access point software would be available on the HP Procurve web site, http://www.hp.

B Access Point Port and Network Cables This appendix includes access point connector information and network cable information for cables that should be used with the AP 420 ww/na, including minimum pin-out information and specifications for twisted-pair cables. Note 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.
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 device such as switch or router that provide MDI-X ports.
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.
Access Point Port and Network Cables Twisted-Pair Cable/Connector Pin-Outs Crossover Twisted-Pair Cable for 10 Mbps or 100 Mbps Network Connection Because the 10/100 port on the access point uses an MDI pin configuration, you must use “crossover” cable for network connections to PCs, servers or other end nodes that only have MDI ports. However, if the device to which you are connecting supports auto-MDIX operation, you can use either “straightthrough” or “crossover” cable.
