Power on and power off the server
Follow the instructions in this section to power on and power off the server.
Power on the server
After the server performs a short self-test (power status LED flashes quickly) when connected to input power,
it enters a standby state (power status LED flashes once per second).
Power button location and power LED are specified in:
•
Chapter 2 “Server components” on page 13
• “Troubleshooting by system LEDs and diagnostics display” on page 198
The server can be turned on (power LED on) in any of the following ways:
• You can press the power button.
• The server can restart automatically after a power interruption.
• The server can respond to remote power-on requests sent to the Lenovo XClarity Controller.
For information about powering off the server, see
“Power off the server” on page 42.
Power off the server
The server remains in a standby state when it is connected to a power source, allowing the Lenovo XClarity
Controller to respond to remote power-on requests. To remove all power from the server (power status LED
off), you must disconnect all power cables.
Power button location and power LED are specified in:
•
Chapter 2 “Server components” on page 13
• “Troubleshooting by system LEDs and diagnostics display” on page 198
To place the server in a standby state (power status LED flashes once per second):
Note: The Lenovo XClarity Controller can place the server in a standby state as an automatic response to a
critical system failure.
• Start an orderly shutdown using the operating system (if supported by your operating system).
