Power on and power off problems
Use this information to resolve issues when powering on or powering off the server.
Server does not power on
Check the event log for any events related to the server not powering on.
Check for any LEDs that are flashing amber.
Check the LEDs on the system board assembly. See System-board-assembly LEDs.
Check if AC power LED is lit on or the amber LED is lit on at the PSU rear side.
AC cycle the system.
Remove the CMOS battery for at least ten seconds, then, reinstall the CMOS battery.
Try to power on the system by IPMI command through XCC or by the power button.
Implement the minimum configuration (one processor, one DIMM and one PSU without any adapter and any drive installed).
Reseat all power supplies and make sure that AC LEDs on the PSU rear side are lit.
Replace the each power supply and check the power button function after installing the each one.
If the issue cannot be resolved by above actions, call service to review the issue symptom and see whether the system I/O board or processor board replacement is necessary.
Server does not power off
- Determine whether you are using an Advanced Configuration and Power Interface (ACPI) or a non-ACPI operating system. If you are using a non-ACPI operating system, complete the following steps:
Turn off the server by pressing the power-control button and holding it down for 5 seconds.
Restart the server.
If the server fails POST and the power-control button does not work, disconnect the power cord for 20 seconds; then, reconnect the power cord and restart the server.
If the problem remains or if you are using an ACPI-aware operating system, suspect the system board (system board assembly).
