Abstract
A computer system is adapted for dynamic replacement of a hot swap controller card. The computer system includes a circuit board, with the computer system comprising a first slot and a second slot coupled to the circuit board. The first slot includes a first connector and the second slot includes a second connector. The first and second connectors each have a column and row arrangement of connector-pins, with the first connector including first, second and third connector-pins and the second connector including fourth, fifth and sixth connector-pins. First, second, third, fourth, fifth and sixth signal lines are connected to the first through sixth connector-pins, respectively. A primary hot swap controller has a first means for simultaneously turning on/off a first plurality of switches, a second means for driving signal lines connected to the first, second, fourth, and fifth connector-pins, and a third means for storing a status information of the signal lines. A backup hot swap controller has a fourth means for simultaneously turning on/off a second plurality of switches, a fifth means for driving the signal lines connected to the first, second, fourth, and fifth connector-pins …
