About the Radio Upgrade Kit In the MobileLAN access WA21, you may need to add a second radio, replace a malfunctioning radio, or remove one type of radio and replace it with another type of radio. These instructions explain how to add or replace a radio, how to reconfigure the configuration matrix string, and how and where to apply the new labels. At the end of these instructions you can find some troubleshooting information. Note: The country code is programmed into the radio at the factory. The country code should always remain the same in an access point. You should not upgrade an access point with a radio with a different country code. There are three radio upgrade kits that you can order: 802.11b Radio (P/N RWA21A704) 802.11a Full-Range Radio (P/N RWA21A904) 802.11a Mid-Range Radio (P/N RWA21A954) • Mini-PCI radio • Mini-PCI radio card • Mini-PCI radio card • Retainer clip • Retainer clip • Retainer clip • RF certification • RF certification label • RF certification label • Radio upgrade kit • Radio upgrade kit card label • Radio upgrade kit label label label • Antenna cable • Antenna cable • Antenna cable assemblies (2) assemblies (2) assemblies (2) • Antennas (2) To maintain the IP54 rating, Intermec recommends that you also replace this part: • Gasket (P/N 065194-002) You need these tools: • Torx T20 (to open the access point) • Ratchet with 16 mm (5/8 in) socket • 16 mm (5/8 in) open-ended socket wrench MobileLAN WA21 Radio Replacement Instructions • Calibrated torque screwdriver You may also need these tools: • Scissors (to trim the RF certification label) Integrated circuits on the printed circuit board (PCB) in the access point are very sensitive to damage by electrostatic discharge (ESD). Prevent ESD by always wearing skin contact ground straps firmly attached to the equipment metal base assembly when working inside the access point. Never open the unit package without safeguarding the entire work area with ESD protection. Failure to comply may result in damage to PCB components.

Gasket Alignment 2100I.003 MobileLAN WA21 Radio Replacement Instructions Installing the Labels Once you have finished installing a new radio in the access point, you need to apply the new RF certification label and the radio upgrade kit label. Label locations WA21I011.eps To label the access point 1 Apply the RF certification label. • If you replaced an existing radio, trim the blank portion off the new RF certification label. Place the printed portion on top of the existing RF certification label. Be sure the original label containing the access point model and serial numbers and other identifying information remains visible. MobileLAN WA21 Radio Replacement Instructions • If you added a second radio to the access point, place the entire RF certification label in the blank space on the back of the access point. 2 Apply the radio upgrade kit label. • If you replaced an existing radio, place the small radio upgrade kit label to the right of all existing labels. Do not cover up any existing labels. • If you added a second radio to the access point, place the small radio upgrade kit label in the blank area on the radio certification label you applied in Step 1. Reconfiguring the Configuration Matrix String The configuration matrix string is a 14-character string indicating the model of access point and the radios installed in it. When the access point boots, it compares the configuration matrix string to the installed hardware. If the configuration matrix string and the installed hardware do not match, the access point indicates an error and does not boot. For the access point to boot properly, you must reconfigure the configuration matrix string to identify the radio you just installed. To reconfigure the configuration matrix string, you need the 3digit code that identifies the radio in this kit. This code appears on the shipping label on the outside of the radio replacement kit. The format of the configuration matrix string is: xxxxxxxx111222 where: xxxxxxxx identifies the model of the access point 111 identifies the radio in slot 1 222 identifies the radio in slot 2 For example, a possible configuration matrix string for a model WA21 with an 802.11b radio in slot 1 and no radio in slot 2 is WA21A511704000. To reconfigure the configuration matrix string 1 Locate the original configuration matrix string. This string appears after the characters C/N on the original radio 10 MobileLAN WA21 Radio Replacement Instructions certification label. Note the first eight characters of the configuration matrix string—these are the first eight characters in the new configuration matrix string. 2 Identify the radios in slots 1 and 2. The shipping label on the radio upgrade kit box contains the 3-digit code or you can use this table: Radio 3-Digit Code 802.11b radio 704 802.11a full-range radio 904 802.11a mid-range radio 954 No radio 000 3 Write down the new 14-character configuration matrix string. 4 Connect the access point to a terminal or PC using an RS232 null modem cable. 5 Plug the power cable into a power source and then into the access point. The access point boots. 6 When the messageappears, press a key to enter the UAP Monitor. 7 At the AP (ap>) prompt, type zmt and press Enter. 8 In the password field, type matrix and press Enter. 9 Type ma xxxxxxxx111222, where xxxxxxxx111222 is the new configuration matrix string. Press Enter. When you enter a valid configuration matrix string, the confirmation message “passed” appears on the screen. 10 Type x and press Enter to exit the matrix menu. 11 At the AP prompt, type mr to verify the configuration matrix string. The manufacturing record appears onscreen, including the configuration matrix string. 12 Type b and press Enter to reboot the access point. MobileLAN WA21 Radio Replacement Instructions 11 Completing a Radio Upgrade 1 You may want to upgrade the access point software to the latest release before you upgrade the radio. To download the latest software release, check the Intermec MobileLAN Web site at http://mobilelan.intermec.com. 2 Restore the access point to its factory default settings. From the Maintenance menu, choose Read Factory Default Configurations, and then from the main menu choose Save Configuration. Reboot the access point so the default configuration becomes active. The reboot process may take up to 4 minutes to complete. Do not power-cycle or reboot the access point during the reboot process or the radio firmware will be destroyed. 3 Reconfigure the access point settings. Refer to the configuration settings you noted before you opened the access point. Confirm that the access point is working properly, reinstall it in the network, reattach the cables, and replace the cable access door. You have successfully upgraded the access point. Troubleshooting the Radios If you are still having problems communicating with the wireless network, you can use the access point LEDs, a serial connection, or the access point to help you troubleshoot any radio problems. Using LEDs If the access point LEDs show the following pattern after it boots, the radio may be faulty or the configuration matrix string is incorrect. Power Wireless #1 Wireless #2 Wired LAN Root/Error Using a Communications Program or a Telnet Session If you are communicating with the access point using a communications program or a telnet session, an error message 12 MobileLAN WA21 Radio Replacement Instructions may appear on your PC after the access point reboots or when a session is saved. The error messages are described in the following table. In this table, radio A refers to the radio in slot 1 and radio B refers to the radio in slot 2. Error Message Explanation Couldn’t read country code from radio A The radio may be faulty. Invalid country code in string for radio A The country code in the configuration matrix string does not match the country code in the radio in the access point. Radio A has unknown country code The radio may have been configured incorrectly at the factory.
