Server power features
When the server is connected to a suitable input source but is not turned on, the operating system does not
run, and all core logic except for the service processor (the integrated management module) is shut down.
However, the server can respond to requests to the service processor, such as a remote request to turn
on the server. The power-on LED flashes to indicate that the server is connected to input power but is not
turned on.
Turning on the server
Use this information to turn on the server.
Approximately 5 seconds after the server is connected to input power, one or more fans might start running
and the power-on LED flashes quickly. Approximately 10 seconds after the server is connected to input
power, the power-on button becomes active. After the power-on button becomes active, the power-on LED
flashes slowly. You can turn on the server by pressing the power-on button.
Step 1.
Press the power-on button to turn on the server.
Step 2.
The server can also be turned on in any of the following ways:
• If a power failure occurs while the server is turned on, the server will restart automatically when
power is restored.
• If your operating system supports the Wake on LAN feature, the Wake on LAN feature can turn
on the server.
What to do next
1. When 4 GB or more of memory (physical or logical) is installed, some memory is reserved for various
system resources and is unavailable to the operating system. The amount of memory that is reserved
for system resources depends on the operating system, the configuration of the server, and the
configured PCI options.
2. When you turn on the server with external graphical adapters installed, the Lenovo logo displays on the
screen after approximately 3 minutes. This is normal operation while the system loads.
3. Make sure the left-side cover is closed.
Turning off the server
Use this information to turn off the server.
When you turn off the server and leave it connected to input power, the server can respond to requests to
the service processor (the Integrated Management Module II (IMM2)), such as a remote request to turn on
the server. While the server remains connected to input power, one or more fans might continue to run. To
remove all power from the server, you must disconnect it from the power source.
Some operating systems require an orderly shutdown before you turn off the server. See your
operating-system documentation for information about shutting down the operating system.
