GTGH boards are randomly reset and mark "Last restart reason: Watchdog Unfed".
I don't know if it's a version problem and i have to upgrade to 2.1. or it is an incompatibility between the controller board (SCXN) and the PON boards and i have to put an SCTM controller.
Today we will be with 3000 onus in the C300.
