Performing a Factory Reset

The TeSys island system can be reset to factory settings, returning the bus coupler to its out-of-the-box conditions. This is useful, for example, to quickly get to Test mode when building or modifying an island.

TeSys island accepts a Factory Reset command from the digital tool (TeSys island DTM or OMT) with exclusive control when the system is in Pre-Operational mode, Test mode, or Minor Event state.

Upon receiving a Factory Reset command, TeSys island

Deletes the following files:
- system context files (active, pending, and SDP if present)
- SEDP files (including active, pending, or update)
- Users file
Automatically restarts

NOTE:

When the Users file is deleted, any added users are removed. In addition, the group management and the administrative password are reset to default values.
A Factory Reset command does not delete log files.
