An apparatus, system, and method are disclosed for identifying and differentiating among multiple groups of devices, comprising at least two LEDs, a controller, and a blending medium. The at least two LEDs emit a wavelength of light that is different from a wavelength of each other LED. The controller drives the at least two LEDs to each emit light at specified intensities in response to a color identifying value. The blending medium combines the light emitted by the at least two LEDs into an identifying color that identifies a group of devices.

Methods, apparatus, and products are disclosed for dynamically configuring overcurrent protection in a power supply for components of an electrically powered system, including summing by a master service processor, during powered operation of the system, the present power requirements of components presently installed in the system and setting by the master service processor an overcurrent trip point of the power supply in dependence upon the sum of the present power requirements of the components.

Dynamically configuring overcurrent protection in a power supply

A method and system for monitoring and adapting to configuration changes in a data processing system having a known configuration, while power is applied thereto. In response to a configuration change in the data processing system, values are calculated for multiple system operating factors. An alert is provided to a user if at least one of said calculated values, among the multiple system operating factors, is not within a predetermined range of values for the multiple system operating factors. In addition, the operation of the data processing system is restricted to accommodate for any system operating factors which are not within the predetermined range of values, such that the data processing system is guarded from damage due to an unstable configuration.

Method and system for monitoring configuration changes in a data processing system

A method of configuring a data communications system, by changing a default communications address of a logic component to a first assigned address, and connecting the logic component to a communications bus automatically in response to the address change. The logic component may include a multiplexer having an input connected to a first communications bus, and several outputs, some of the outputs being connected to input/output (I/O) devices, and at least one of the outputs being connected to a second communications bus. The latter output is disabled when the logic component has the default communications address; the logic component is connected to the second communications bus by enabling the output of the multiplexer. The invention is particularly adapted for use with a computer system, wherein a service processor having an I C port is connected to the first communications bus, and the service processor communicates with the logic component using an I C bus protocol to send data across the first communications bus to an input/output expander of the second logic component.

A labeling system combines an indelibly inscribed visually readable serial number with an embedded electronically readable one-time programmable read-only storage device. The integration of the two in one labeling system ensures that the visually readable identification information is consistent with the electronically readable information. The labeling system is tamper evident visually and electronically. Electronic tamper evidence is provided by the construction of the label system which is designed to ensure the breaking of various internal and peripheral electrical connections associated with the embedded read-only storage device during any attempt to remove the label once it is affixed to the computer or subassembly thus identified. The integration of visual and electronic identification information eliminates the need to manually or electronically enter the identification information into the electronic storage device during a separate manufacturing process. The labeling system may be affixed to computer system enclosures, subassemblies, adapter cards, and even components mounted on such subassemblies and adapter cards.
