ABSTRACT:
An electronic equipment comprises a first computer, a first power line over which power is supplied to the first computer, a second computer, a second power line over which power is supplied to the second computer, and a switch having one terminal thereof connected with a data bus to which the first computer is connected, and having the other terminal thereof connected with a data bus to which the second computer is connected. When power is supplied to the second computer over the second power line, the switch connects the data bus to which the first computer is connected with the data bus to which the second computer is connected. When no power is supplied to the second computer over the second power line, the switch isolates the data bus to which the first computer is connected from the data bus to which the second computer is connected.
