Using the Mode Button
Using the
Mode
button (see
Figure 2: C9136I Top View with Connectors and Ports, on page 6
) you can
perform the following tasks:
• Reset the AP to the default factory-shipped configuration.
• Clear the AP internal storage, including all the configuration files.
To use the
Mode
button, press, and continue to press the
Mode
button on the access point during the AP boot
cycle. Wait until the AP console shows a seconds counter. When the counter indicates the number of seconds
for which the
Mode
button is pressed, the AP status LED changes to blinking red. Then:
• To reset the AP to the default factory-shipped configuration, keep the mode button pressed for less than
20 seconds. The AP configuration files are cleared.
This resets all the configuration settings to factory defaults, including passwords, WEP keys, the IP address,
and the SSID.
• To clear the AP internal storage, including all the configuration files, keep the
Mode
button pressed for
more than 20 seconds, but less than 60 seconds.
If the
Mode
button is pressed for more than 30 seconds, but less than 60 seconds, the FIPS mode flag is also
cleared during the full factory reset of the AP. If the FIPS flag is set, console access if disabled.
Note
The AP status LED changes from blue to red, and all the files in the AP storage directory are cleared.
If you keep the
Mode
button pressed for more than 60 seconds, the button is assumed as being faulty and no
changes are made.
