MobileLAN WA21 Radio Replacement Instructions 1

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:

• 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.
