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 II (IMM2) is shut down; however, the server can respond to
requests from IMM2, such as a remote request to turn on the server. The power-on
LED flashes to indicate that the server is connected to an AC power source but is
not turned on.
Turning on the node
Approximately 5 seconds after the system-board tray is connected to power, one or
more fans might start running to provide cooling while the system-board tray is
connected to power and the power-on button LED will blink quickly. Approximately 5
to 10 seconds after the system-board tray is connected to 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 system-board tray is connected to
power. You can turn on the system-board tray by pressing the power-control button.
The server can also be turned on in any of the following ways:
v
If a power failure occurs while the system-board tray is turned on, the
system-board tray will restart automatically when power is restored.
v
If your operating system supports the Wake on LAN feature, the Wake on LAN
feature can turn on the system-board tray.
Notes:
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 system-board tray, and the
configured PCI options.
2. Ethernet 1 connector supports Wake on LAN feature.
3. When you turn on the system-board tray with external graphical adapters
installed, the IBM logo displays on the screen after approximately 3 minutes.
This is normal operation while the system loads.
