At blade start-up, POST diagnostics test the CPUs, DIMMs, HDDs and adapter cards, and any failure

notifications are sent to UCSM. You can view these notification in the System Error Log or in the output

of the show tech-support command. If errors are found, an amber diagnostic LED will also light up next

to the failed component. During run time, the blade BIOS, component drivers, and OS all monitor for

hardware faults and will light up the amber diagnostic LED for a component if an uncorrectable error or

correctable errors (such as a host ECC error) over the allowed threshold occur.
