The SNE features a recessed Reset button that is located directly above the Heartbeat LED. If you need to reset the SNE but retain the archive and stored historical data, issue a Reset Device command from the user interface. This type of reset is known as a soft reset.
To force an immediate restart of the SNE engine and a reset of the processor, press and immediately release the Reset button with an extended paper clip or mini screwdriver. This action is otherwise known as a hard reset or processor reset.
The data includes all historical information, including alarm, trend, and audit trail data.
