7.2.3 System Identification LED
The system ID LED provides a visual indication of a system being serviced. The state of the
system ID LED is affected by the following:
Toggled by the system 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 system ID LED is blinking
and the system ID button is pressed, then the system ID LED changes to solid on. If the
button is pressed again with no intervening commands, the system ID LED turns off.
