Abstract: A control system for an electric motor, the control system comprising a first control device arranged to control an operation of a first component of the electric motor; a second control device arranged to control an operation of a second component of the electric motor, wherein the first control device is arranged to transmit to the second control device a first signal for indicating the transmission of data over a first communication link to the second control device, wherein the second control device is arranged to use the timing of the first signal to synchronize the operation of the second component with the operation of the first component.

Abstract: Signals to a management module are generated on an occurrence of an event affecting one of a plurality of server blades housed in a common chassis with the management module and aggregated in the management module. Signaling in accordance with this invention may be originated at a number of levels of operation of information handling systems, and distinction can be drawn between an occurrence requiring prompt attention from an operator—an alert—and occurrences where such prompt action is unnecessary. Occurrences signaled are logged for possible later review, and such a log will, in the contemplation of this invention, contain events related to a number of server blades.
