Dear Dell Support Team,

I recently purchased a new Dell PowerEdge R760xs server, and I am experiencing a boot issue.

When I connect the power supply and power on the server, the monitor displays the message:

“AC input detected. Verifying system security...”

After that, the monitor goes into sleep mode instead of continuing to boot to the system setup or operating system installation screen.

I am therefore unable to proceed with the OS installation.

In addition, I noticed that the server’s power button is blinking. Could you please advise what this indicates and whether it is related to the issue?

Please assist me in troubleshooting this problem. Kindly let me know the checks I should perform, or whether this may indicate a hardware fault.
