Diagnostics Button and LEDs
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.
