One of the main tasks of the IPMC is to control the power up and power down of the blade. For
this purpose the IPMC is connected to the on-board power supply module via control and
status lines. Various on-board IPMI sensors provide detailed information on the current power
status of the blade to any interested party connected to the IPMI network.

The following figure gives an overview of the IPMI structure used on-board.
