Patent ID: 8762592

Claim:
An information handling system (IHS) comprising a plurality of server modules, the system comprising: a chassis having a plurality of connectors and a midplane node; server modules, each capable of operating in either a master or slave mode, adapted for selective connection to the chassis at a connector, the connector having an associated digital connector identifier (ID), and wherein the server modules in the chassis comprise one designated master server and at least one slave server; a first circuit for receiving a digital connector ID signal for each connector connected to a server module and wherein the first circuit generates an analog server module output signal related to the connector ID; and a second circuit for comparing the analog server module output signal to a reference signal to generate a first analog signal, wherein: the first analog signal is monitored at each server module; the first analog signal serves to indicate at each server module whether or not the server module is designated as the master server; and the reference signal is configured to change upon removal of the master server.
