System for powering up and powering down a server

摘要

A fault tolerant computer system for powering up and powering down a server through either a local or remote client machine. The remote machine accesses the server by use of a dial-in modem connection. The power up operation brings the server to an operational state such that diagnostics or recovery can be performed even though the operating system software on the server is not operational. Power down is used when diagnosis and maintenance, such as changing a part, needs to be done. Other reasons for power down are for security or power conservation.
