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.

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.
