  • Cage for dynamic attach testing of I/O boards
    Patent number: 6571360
    Abstract: A multiprocessing computer system provides the hardware support to properly test an I/O board while the system is running user application programs and while preventing a faulty board from causing a system crash. The system includes a centerplane that mounts multiple expander boards. Each expander board in turn connects a microprocessor board and an I/O board to the centerplane. Prior to testing, the replacement I/O board becomes a part of a dynamic system domain software partition after it has been inserted into an expander board of the multiprocessing computer system. Testing an I/O board involves executing a process using a microprocessor and memory on a microprocessor board to perform hardware tests on the I/O board. An error cage, address transaction cage, and interrupt transaction cage isolate any errors generated while the I/O board is being tested.
