Abstract

A system, method, and computer-readable medium are disclosed automatic validation of light emitting diodes (LEDs) of disk drives in disk processor enclosures (DPEs) or disk array enclosures (DAEs) during the manufacturing and integration of computer systems. An automated test script is performed in support of the integration of the computer system that includes the LEDs and includes a validation and checking step for the LEDs. A determination is made if a camera is properly calibrated to identify the LEDs as part of the validating and checking step for the LEDs. A DPE or DAE that contains disk drive units that include the LEDs are identified, and an indication is performed as to which LEDs pass or fail.
