Patent ID: 8635488

Claim:
A method for implementing an enhanced availability personality card for a chassis computer system, said method comprising: providing a pair of chassis management modules; each said chassis management module including a switch; connecting said switch of each chassis management module to a primary bidirectional bus and a redundant bidirectional bus respectively connected to the personality card; providing the personality card comprising redundant critical components of a first erasable programmable read only memory (EPROM) and a second EPROM, each EPROM storing Vital Product Data (VPD) and a first temperature sensor and a second temperature sensor sensing temperature; connecting said primary bidirectional bus and said redundant bidirectional bus to said first EPROM and said first temperature sensor and said second EPROM and said second temperature sensor, said primary bidirectional bus and said redundant bidirectional bus providing redundant paths, and enabling continued personality card function with failure of any critical personality card component.
