ABSTRACT:
A radio frequency identifier (RFID) active/passive tag is provided to identify failed sub-CRU and location within a higher level CRU. When an error occurs on the base blade or within one of the sub-CRUs, the embedded processor writes failure information to the RFID. RFID tags may also contain data identifying the locations, of the sub-CRUs of the blade. Thus, when there is a failure, the RFID may report the failed component as well as the location of a failed sub-CRU. Sub-CRUs may also include an embedded processor and RFID tag. When a service action is initiated to repair or replace a blade, the RFID tag may be read by a RFID reader. The RFID reader device may then present failure information, including the identification of the failed sub-CRU and other associated information to the operator. The RFID reader device may also request associated information from a server computer.
