Air Baffles
The air baffles direct and improve air flow for the server components. Two identical baffles ship with each B200 M4 server. No tools
are necessary to install them, just place them over the DIMMs as shown, with the holes in the center of the baffles aligned with the
corresponding motherboard standoffs.

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 UCS
Manager. You can view these notifications in the 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, 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.
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.
If DIMM insertion errors are detected, they may cause the blade discovery to fail and errors will be reported in the server POST
information, which is viewable using the UCS Manager GUI or CLI. UCS blade servers require specific rules to be followed when
populating DIMMs in a blade server, and the rules depend on the blade server model. Refer to the documentation for a specific blade
server for those rules.
