Abstract
A method and circuit for implementing an enhanced availability personality card for a chassis computer system, and a design structure on which the subject circuit resides are provided. The personality card includes 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. A primary bidirectional bus and a redundant bidirectional bus are respectively connected between the first EPROM and the first temperature sensor and the second EPROM and the second temperature sensor, and a pair of chassis management modules. Each chassis management module includes a switch connected to both the primary bidirectional bus and the redundant bidirectional bus providing redundant paths, enabling continued function with failure of any critical personality card component.
