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) Table 36. Chassis ID LED Indicator States State Identify active via button Identify active via command Off LED State Solid on ~1 Hz blink Off There is no precedence or lock-out mechanism for the control sources.
