Hi We tried all these voo-doo's to no avail (each several time for 2-5 min).
We also contacted support (the brick is still under warranty). Support advice was the same (unplug, keep power button or keep reset idrac (i-icon) for 20s). Support gave 2 more hints: (a) clear NVRAM using NVRAM jumper on MB, (b) take off all equipment from a server except CPU #1 , one DIMM, one PSU and system board. Nothing helped. Server does not boot OS, no VGA display, no IP connection to iDRAC, nothing on serial port. The only 2 positives: both PSU have power, disks start flashing after power-on. Support decided to replace MB. Waiting for serviceman ...
