Some history of this also available here.

As of my latest update on the forum linked above, now cold reboot as well as hard reset and following boot for my proliant dl360 g5 works as expected and successfully boot the system.

However, soft-reboot results in internal health indicator turning RED on the front and long beeps every around 6seconds until I either cold reboot or press and hold the power button.

A summary of system state when this happens:

• Internal Health led indicator: RED
• External Health led indicator: Green
• No led next to any component is red or amber
• No POST message neither on the video output nor on IML logs (verified both at the time issue occures and after cold reboot that boots the system successfully).

Any thoughts please share. I hope we can knock this issue down together with your help!
