A first data bus is coupled to communicate information from a subsystem for sensing operating parameters of peripheral components to a computer system. A second data bus is coupled to communicate data between peripheral components and the computer system. A first switch is coupled between the first data bus and the second data bus, the first switch being operable to allow signals from the first data bus to be communicated over the second data bus when operating power to the computer system is powered off. A second switch is coupled between the second data bus and the peripheral components, and the second switch is operable to allow signals from the second data bus to be communicated to the computer system when operating power to the computer system is powered on. |
