AC power LED
When this LED is lit (green), it indicates that ac power is being supplied to the power supply.
DC power LED
When this LED is lit (green), it indicates that dc power is being supplied from the power supply to the
chassis midplane.
Fault LED
When this LED is lit (yellow), it indicates that there is a fault with the power supply.
Note:
Before unplugging the ac power cord from the power supply or removing the power supply from
the chassis, verify that the capacity of the remaining power supplies are sufficient to meet the minimum
power requirements for all components in the chassis.
Server power features
When the server is connected to an ac power source but is not turned on, the operating system does not run,
and all core logic except for the Integrated Management Module 2.1 (IMM2.1) is shutdown.
However, the server can respond to requests from Integrated Management Module 2.1 (IMM2.1), such as a
remote request to turn on the server. The power-on LED flashes to indicate that the server is connected to ac
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 ac power, one or more fans might start running to
provide cooling while the server is connected to power and the power-on button LED will blink quickly.
Approximately 1 to 3 minutes after the server is connected to ac power, the power-control button becomes
active (the power-on LED will blink slowly), and one or more fans might start running to provide cooling while
the server is connected to power. You can turn on the server by pressing the power-control 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.
Note:
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.
Turning off the server
Use this information to turn off the server.
When you turn off the server and leave it connected to ac power, the server can respond to requests from
Integrated Management Module 2.1 (IMM2.1), such as a remote request to turn on the server. While the
server remains connected to ac 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.
