R250,R350,T150,T350: First power on need wait for 2-3 mins and Power button LED is off after pressing the power button

Customer may complain the R250,R350,T150, T350 power button is not workable (Power button LED is off after pressing Pwr Button) at the first power on.

The R250, R350, T150, T350 need complete the Idrac initialization at the first power on. It takes about 2-3 mins. During this period, its power button LED is keeping OFF status whatever press the power button or not.  If monitor is connected, customer could read the words "Idrac is initializing. Frist power on may be delayed...", like below picture.

This behavior only happens at the first power on after the server performed the AC power drain or the OOB unit.

Please do not replace any hardware components. Dell engineers are aware of it and are going to change PWR button behavior from OFF to breathing if user presses the power button at idrac initializing period. So that user can more easily know the server status from the front panel. 
Dell engineers are working to cut in this solution on the CPLD, the improvement CPLD version is 1.0.1 or later. 
Note: If user encounters the problem during update CPLD FW from 1.0.0 or 1.0.1, please refer PSQN: LKB 000198532.
