Power supply

Due to a problem with a power supply from a visitor's laptop various issues were raised. The main point was that this problem caused essential computers for operations to fail. We are reviewing the current situation as for the connection to the UPS and the generator, where we want to define how to protect operational critical systems (specifically the computers). One specific idea is to have all computer on their own specific cable with nothing else connected and with an independent fuse and earth-leakage breaker at the switch board.
