    摘要: A state machine is used to remove residual electric charge from a sense line and to sample the voltage of the sense line at multiple pre-determined times to determine the presence of a terminating capacitor and its value. Various values of capacitors identify discrete conditions. These discrete conditions may identify different types of plug-in cards or models of plug-in cards within a group type.

    摘要: A data storage and retrieval system that comprises a data storage device is disclosed. The data storage and retrieval system further comprises a first LED, a second LED, a third LED, and a fourth LED, interconnected with the data storage device. The data storage device causes the first LED and the second LED to emit first light comprising a first color if the data storage device detects an internal failure. Alternatively, the storage device causes the third LED and the fourth LED to emit second light comprising a second color if the data storage device remains operative.
