TOFp System Procedure:
DAQ PC Reboot After Crash


   Description:
The DAQ PC is a dual boot machine. One is the "Mini-System" and the other is for normal operations. If for any reason the DAQ PC crashes (power failure, loss of SGIS Global Permissive...) the DAQ PC will boot with the Mini-System. Rebooting "minimally" improves the chances that we can get back in touch with this PC over the network. If any kind of DAQ PC crash occurs, this is the procedure to log in and reboot the DAQ PC to prepare for normal running.
