Patent ID: 7831860

Claim:
A system for testing redundancy and hot-swapping capability of a redundant power supply, the system comprising: a power switch fixture comprising a processor, an alternating current (AC) source, a first relay, a second relay, and two AC outputs; a system under test (SUT) comprising a redundant power supply that comprises a first power supply and a second power supply configured for providing power to the SUT; and a computing device comprising: a parameter setting module configured for setting a hot-swap iteration for switching the first power supply and the second power supply; a command generating module configured for generating a plurality of commands comprising a hot-swap command, a control command, and a monitor command; a controlling module configured for controlling the processor to switch the first power supply and the second power supply by switching one of the first and the second relay on and one of the first and the second relay off according to the hot-swap command, and controlling the computing device to test different operations of the SUT according to the control command; a monitoring module configured for monitoring hot-swapping operations on the redundant power supply and working states of the SUT under different operations according to the monitor command; and a report generating module configured for generating a test report that indicates redundancy and hot-swapping capability of the redundant power supply according to the working states of the SUT.
