The power-control button does not work, and the reset button does not work (the server does not start).The power-control button will not function until approximately 20 seconds after the server has been connected to power. | - Make sure that the power-control button is working correctly:
- Disconnect the server power cords.
- Reconnect the power cords.
- (Trained technician only) Reseat the operator information panel cable, and then repeat steps 1a and 1b.
- (Trained technician only) If the server starts, reseat the operator information panel. If the problem remains, replace the operator information panel.
- If the server does not start, bypass the power-control button by using the force power-on jumper (see System-board switches, jumpers, and buttons). If the server starts, reseat the operator information panel. If the problem remains, replace the operator information panel.
- Make sure that the reset button is working correctly:
- Disconnect the server power cords.
- Reconnect the power cords.
- (Trained technician only) Reseat the operator information panel cable, and then repeat steps 2a and 2b.
- (Trained technician only) If the server starts, replace the operator information panel.
- If the server does not start, go to step 3.
- Make sure that both power supplies installed in the server are of the same type. Mixing different ratings of power supplies in the server will cause a system error (CONFIG icon will be shown on the LCD system information display panel).
- Make sure that:
- The power source meets the minimum voltage requirement for the installed power supplies.
- The type of memory that is installed is correct.
- The DIMMs are fully seated.
- The LEDs on the power supply do not indicate a problem.
- The microprocessors are installed in the correct sequence.
- Reseat the following components:
- Operator information panel connector
- Power supplies
- Replace the components listed in step 5 one at a time, in the order shown, restarting the server each time.
- If you just installed an optional device, remove it, and restart the server. If the server now starts, you might have installed more devices than the power supply supports.

| Pwr rail 1 error has been recorded in the system event log. | - Disconnect the server power cords.
- (Trained technician only) remove microprocessor 1 if the Pwr rail 1 error has been recorded in the system event log.
- (Trained technician only) replace the system board (see For service technician only: removing the system board and For service technician only: replacing the system board).
- Reinstall the component; then, restarting the server. If the Pwr rail 1 error has been recorded in the system event log again, the component that you just reinstalled is defective. Replace the defective component.
|
| Pwr rail 2 error has been recorded in the system event log. | - Disconnect the server power cords.
- (Trained technician only) remove microprocessor 2 if Pwr rail 2 error has been recorded in the system event log.
- Restart the server. If the Pwr rail 2 error has been recorded in the IMM event log again, (trained technician only) replace the system board (see For service technician only: removing the system board and For service technician only: replacing the system board).
- Reinstall the component; then, restarting the server. If the Pwr Rail 2 error has been recorded in the system event log again, the component that you just reinstalled is defective. Replace the defective component.
|
| Pwr rail 3 error has been recorded in the system event log. | - Disconnect the server power cords.
- Remove the following components if Pwr rail 3 error has been recorded in the system event log:
- Restart the server. If the Pwr rail 3 error has been recorded in the system event log again, (trained technician only) replace the system board (see For service technician only: removing the system board and For service technician only: replacing the system board).
- Reinstall the components one at a time, in the order shown, restarting the server each time. If the Pwr rail 3 error has been recorded in the system event log again, the component that you just reinstalled is defective. Replace the defective component.
|
| Pwr rail 4 error has been recorded in the system event log. | - Disconnect the server power cords.
- Remove the following components if the Pwr rail 4 error has been recorded in the system event log:
- Fan 5
- Fan 6
- DIMMs 13 through 24
- Restart the server. If the Pwr rail 4 error has been recorded in the system event log again, (trained technician only) replace the system board (see For service technician only: removing the system board and For service technician only: replacing the system board).
- Reinstall the components one at a time, in the order shown, restarting the server each time. If the Pwr Rail 4 error has been recorded in the system event log again, the component that you just reinstalled is defective. Replace the defective component.
|
| Pwr rail 5 error has been recorded in the system event log. | - Disconnect the server power cords.
- Remove the following components if the Pwr rail 5 error has been recorded in the system event log:
- Fan 7
- Fan 8
- SAS/SATA hard disk drives and USB
- Restart the server. If the Pwr rail 5 error has been recorded in the system event log again, (trained technician only) replace the system board (see For service technician only: removing the system board and For service technician only: replacing the system board).
- Reinstall the components one at a time, in the order shown, restarting the server each time. If the Pwr Rail 5 error has been recorded in the system event log again, the component that you just reinstalled is defective. Replace the defective component.
|
| Pwr rail 6 error has been recorded in the system event log. | - Disconnect the server power cords.
- Remove the following components if the Pwr rail 6 error has been recorded in the system event log:
- Optional cable for VGA external power
- PCI-E x8 and x16 (maximum expansion is 4 adapter cards)
- PCI-E hard disk drives
- Restart the server. If the Pwr rail 6 error has been recorded in the system event log again, (trained technician only) replace the system board (see For service technician only: removing the system board and For service technician only: replacing the system board).
- Reinstall the components one at a time, in the order shown, restarting the server each time. If the Pwr Rail 6 error has been recorded in the system event log again, the component that you just reinstalled is defective. Replace the defective component.
|
| Pwr rail 7 error has been recorded in the system event log. | - Disconnect the server power cords.
- Remove the following components if the Pwr rail 7 error has been recorded in the system event log:
- Restart the server. If the Pwr rail 6 error has been recorded in the system event log again, (trained technician only) replace the system board (see For service technician only: removing the system board and For service technician only: replacing the system board).
- Reinstall the components one at a time, in the order shown, restarting the server each time. If the Pwr Rail 6 error has been recorded in the system event log again, the component that you just reinstalled is defective. Replace the defective component.

| The server does not turn 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:
- Press Ctrl+Alt+Delete.
- Turn off the server by pressing the power-control button and hold 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.
