Type 2: Hard Reset
A hard reset deletes all trend, alarm, and transient data, and wipes the executing
configuration and the ID of its host controller.
A hard reset does not delete the module connection information, including any
saved IP address or the saved configuration.
A type 2 hard reset is executed by sending a type 2 reset service.
Because a module immediately loads its configuration from nonvolatile
memory and begins monitoring, a module does not persist in its hard reset
state.
Reset Procedures
The following table summarizes the information that is held in the volatile and
nonvolatile memories, and indicates what each type of reset deletes.
Delete on Reset

Hardware Type 0 Common Reset
To perform a type 0 common reset, follow this procedure:
1. Disconnect power from the module.
2. Wait at least 2 seconds.
3. Restore power to the module.
The module powers up and connects to the network that uses the connection
information previously established. After completing its self-test procedure,
the module loads the configuration that is saved in nonvolatile memory and
begins monitoring.
