J9051A and J9052A Buttons:
Shutdown Module This is a recessed push button switch that when pressed and held for more than 2
seconds, initiates an orderly shutdown. During the shutdown process the Module Ready
LED blinks and you will be prompted to save any changes. When the shutdown is
complete enough for a safe module removal, the Module Ready LED turns off. It is highly
recommended to shutdown the module before resetting or removing the module.
Reset Module This is a recessed push button switch. When this button is pressed it causes an
immediate reset of the module's hardware, without an opportunity to save any changes.
Pressing this button after the shutdown completes will initiate an orderly restart of the
module.
