Quick and accurate detection and reporting of component failures using RFID
First Claim
1. An apparatus comprising:
- a radio-frequency identification tag associated with a first electronic component of a computer system, the component being installed on a common communications bus and power bus among at least one other electronic component wherein failure of a component may cause disruption of the power bus, the communications bus, or both power and communications busses;
a system-level diagnostic function within the computer system but external to the first electronic component configured to receive a diagnostic failure indication from the first electronic component, and responsive to receipt of the diagnostic failure indication, to send a latching signal to the first electronic component; and
a latch controllable by the latching signal, the latch having at least two stable modes including an unlatched mode which prevents the tag from transmitting signals upon query by a radio-frequency identification reader, and a latched mode which enables the tag to transmit signals upon query by a radio-frequency identification reader.

Abstract
Component failures are reported using a radio-frequency identification tag associated with an electronic component of a computer system installed on a common communications bus and power bus among at least one other electronic component wherein failure of a component may cause disruption of the power bus, the communications bus, or both busses; a system-level diagnostic function within the computer system but external to the first electronic component receiving a diagnostic failure indication from the first electronic component, and responsive to receipt of the diagnostic failure indication, sending a latching signal to the first electronic component; and a latch controllable by the latching signal, the latch having at least two stable modes including an unlatched mode which prevents the tag from transmitting signals upon query by a radio-frequency identification reader, and a latched mode which enables the tag to transmit signals upon query by a radio-frequency identification reader.

9. An automated method comprising:
-
providing a radio-frequency identification tag associated with a first electronic component of a computer system, the electronic component being installed on a common communications bus and power bus among at least one other electronic component wherein failure of a component may cause disruption of the power bus, the communications bus, or both power and communications busses; receiving by a system-level diagnostic function a diagnostic failure indication from the first electronic component, the system-level diagnostic function being within the computer system but external to the first electronic component; responsive to receipt of the diagnostic failure indication, send a latching signal from the component-external system-level diagnostic function to the first electronic component; and responsive to receiving the latching signal by the first electronic component;
controlling a tag latch to operate in at least two stable modes including an unlatched mode which prevents the tag from transmitting signals upon query by a radio-frequency identification reader, and a latched mode which enables the tag to transmitting signals upon query by a radio-frequency identification reader. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
