In IBM systems, we have a feature called LampTest. This is a feature to check if all the Indicator LEDs are working ( like in terms of Solid On / Blink ) per expectation. How exactly a LampTest is implemented is per the needs of a system. Would Redfish be interested to put LampTest initiator in the Systems schema may be ?. Since LED being so integral part of a systems, I am hoping introducing LampTest would be a very valuable addition to Redfish..
