Power control button does not work
The power-control button does not work, and the reset button does work (the server does not start).
Note The power control button does not function until approximately three minutes after the server has been connected to AC power.
Approximately five seconds after the server is connected to power, the power-on LED will blink quickly (three flashes per second). Approximately three minutes after the server is connected to power, the power-on LED will blink slowly (one flash per second)
You must wait for the power-on LED to blink slowly (one flash per second) before pressing the power button. If you press the power button while the power-on LED is blinking quickly (three flashes per second), the server will not turn on.
Troubleshooting steps
Procedure
- Disconnect the server power cords.
- Connect a customer-provided keyboard, mouse, and monitor to the server.
- Reconnect the power cords.
- Check the LEDs on the system board. For some components, such as DIMMs and fans, these LEDs can help you identify the problem. For other components, these LEDs are not useful.
- Make sure that:
The power cords are correctly connected to the server and to a working electrical outlet.
The type of memory that is installed is correct.
The DIMMs are fully seated and in the correct sequence for the application that is running on the server.
The LEDs on the power supply do not indicate a problem.
- Reseat the DIMMs.
- Reseat the power supplies.
- Replace the DIMMs as needed. Restart the server after replacement.
- Replace the power supplies, one at a time. Restart the server after each replacement.
- 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.
- Replace the server.
