Computer system status display panel and method of performing service

A computer system and method of performing service thereto includes a centralized system status panel to identify and display the status of all field replaceable units (FRUs) within the computer system. The system uses electronic signaling such as LEDs on the system status panel to identify the presence and state of the FRUs within the system. The system further may use color differentiation to identify specific FRUs within the system. The system status panel may also include spatial locators to determine the location of the field replaceable units. Acronyms or symbols for the FRUs may further be included on the system status panel. Additionally, the computer system uses color differentiation on user accessible components and their interface features. Color differentiation on the user interface areas may allow a service technician to quickly identify where on the enclosures or individual component handling is possible or desirable. In addition, the computer system may use captive fasteners for the FRUs. Using color differentiation or other similar identification means, fasteners are identifiable by a hierarchy of use. Fasteners such as screws or pins which secure a component are distinguishable from those that secure the chassis of the computer system.
