Chassis ID LED

The chassis ID LED provides a visual indication of a system being serviced. The state of the
chassis ID LED is affected by the following:

Toggled by the chassis ID button

Controlled by the Chassis Identify command (IPMI)

Controlled by the Chassis Identify LED command (OEM)
There is no precedence or lock-out mechanism for the control sources. When a new request
arrives, all previous requests are terminated. For example, if the chassis ID LED is blinking and
the chassis ID button is pressed, then the chassis ID LED changes to solid on. If the button is
pressed again with no intervening commands, the chassis ID LED turns off.
