Installing the 9G426-02 Module

The Reset Switch

The Reset switch is located on the front panel, under the top plastic tab as shown 
in Figure 2-6. It serves three functions: resetting the i960 processor, shutting down 
the module, or restarting the module.

•

To reset the i960 processor, press the reset switch twice within three seconds.

•

To shut down the module, press and hold the reset switch down for three or 
more seconds. 

•

To restart the module after it has been shut down, press and release the Reset 
Switch. 

For security, SNMP management can be used to disable the functions of this 
switch.
