Abstract

PROBLEM TO BE SOLVED: To specify the cause of a failure where a distributed computer does not normally work despite application of its AC power supply by managing both AC and DC power supply states and the communication state of the distributed computer based on a power supply state table and notifying a host computer of those said states of the computer. SOLUTION: A control part 15 instructs an AC power control part 14 to apply the AC power supply of a distributed computer 20 that is instructed by a host computer 1. At the same time, it's decided whether the power application result given from the part 14 is normal or not. Then the decided normal or abnormal result is recorded in the AC power supply state area of a power supply state table 16. In the same way, the normal or abnormal results of the DC power supply state and the communication state are recorded in the DC power supply and communication state areas of the table 16 respectively. Thus, the AC and DC power supply state and the communication state of the computer 20 are managed via the table 16 and these states are notified to the computer 1.
