SmartX Server Reset Functions

There are four different types of reset for the SmartX servers: warm start, cold start, reset, and reset to DFU mode. Depending on the type of reset, the SmartX server can be reset using the reset button or a command from WorkStation.

You can use a straigthened segment of a paper clip or a similar tool to press the reset button.

Parameters and variables that are used to define the system or contain important data in the SmartX server can be retained in a permanent memory. These parameters and variables are automatically saved in the event of power failure, or request for restart and are reloaded after startup.

You can define what kind of events that retention for the parameters and variables should apply.

Retain Levels for Variables

Variables have a configurable retain level, which controls if the value of the variable is retained after a restart of the SmartX server. There are three retain levels:

No
Warm start
Cold start

The following table lists what is retained after a warm start, cold start, or reset based on the configured retain level.
