Parameters and variables that are used to define the system or contain important data in the SmartStruxure server device 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 SmartStruxure server device. 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.

Configuration and Historic Database

A number of parameters describe the current configuration. The historic database contains information collected from different sources. Parameters and historic database are retained at both Warm and Cold start.

DFU Mode

The Device Firmware Upgrade mode can be used if the SmartStruxure server device does not communicate in its normal operating mode. In the DFU mode, with a PC connected to the USB device port on the SmartStruxure server device, the Device Administrator can be used to update the firmware.
