Abstract

A fault tolerant computer system for obtaining and displaying, or updating the status of server components through a remote interface and either a local or remote client machine without intervention of the server operating system software. The remote machine accesses the server by use of a dial-in modem connection, while the local machine accesses the server by a local serial connection. The components that can be monitored include, but are not limited to, the following: Power Supplies, Temperatures, Fans, Processors, I/O Groups, I/O Canisters, Serial Numbers, and Revisions.
