This article describes a technique for getting all the nodes in a distributed data processing (DDP) system powered up when some nodes are in unattended locations. In the technique disclosed herein an optional version of an insertion ring attachment is defined, which, upon reflection of a specific restricted broadcast command, raises a signal to the local power supply causing the entire node to power up. The power supply is designed with a small power source that is still available when the main power supply is down. A companion broadcast is used to power down the system.
