10 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 3-
digit 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
