Abstract
A system includes a first computer, a second computer, and an active computer system determining module. The first computer receives a second computer health signal from the second computer indicating a fault in the second computer and generates a first computer system health signal indicating a fault in the first and/or second computer. The active computer system determining module receives the first computer system health signal and generates a standby signal based on the first computer system health signal. The second computer receives the standby signal and disables one or more of its output ports based on the standby signal.
