Method: Press and hold the System ID button for more than five seconds during the boot process.
Effect:
Forces the server into BIOS Progress Mode.
Displays detailed POST information on the screen.
Helps in diagnosing issues that prevent the server from completing POST.
Explanation of Options
Option A: Press and hold the power button for 15 seconds.
Analysis:
Holding the power button for an extended period typically forces a hard shutdown or initiates a power reset.
Does not help in entering BIOS Progress Mode.
Conclusion: Incorrect.
Option B: Enter <F2> when the server tries to POST.
Analysis:
Pressing
However, if the server is not responding during POST, this method may not be effective.
Does not specifically enable BIOS Progress Mode.
Conclusion: Less effective.
Option C: Press and hold the System ID button for more than five seconds.
Analysis:
Pressing and holding the System ID button for over five seconds triggers the server to enter BIOS Progress Mode.
This method is designed for situations where the server is unresponsive during POST.
Conclusion: Correct Answer.
Option D: Disconnect and reconnect the power cables for both PSUs.
Analysis:
Power cycling the server by disconnecting and reconnecting power may not resolve POST issues.
Does not enable BIOS Progress Mode.
Conclusion: Unlikely to help.
