Diagnostics Button and LEDs

At blade start-up, POST diagnostics test the CPUs, DIMMs, HDDs, and rear mezzanine modules, and any

failure notifications are sent to Cisco UCS Manager. You can view these notifications in the Cisco UCS

Manager System Error Log or in the output of the show tech-support command. If errors are found, an amber

diagnostic LED also lights up next to the failed component. During run time, the blade BIOS and component

drivers monitor for hardware faults and will light up the amber diagnostic LED as needed.

LED states are saved, and if you remove the blade from the chassis the LED values will persist for up to 10

minutes. Pressing the LED diagnostics button on the motherboard causes the LEDs that currently show a

component fault to light for up to 30 seconds for easier component identification. LED fault values are reset

when the blade is reinserted into the chassis and booted, and the process begins from its start.

The following figure shows the LED diagnostics button on the Cisco UCS B260 Blade Server.
