The Power Manager is a tool of the LHCb FMC (Farm Monitoring and Control System) which allows - in an OS-independent manner and without requiring expensive network-controlled power distributors - to switch the farm nodes on and off, and to monitor their physical condition: power status (on/off), temperatures, fan speeds and voltages. The Power Manager can operate on farm nodes whose motherboards and network interface cards implement the IPMI (Intelligent Platform Management Interface) specifications, version 1.5 or subsequent, and copes with several IPMI limitations
