Systems-management Ethernet connector:
Use this connector to connect the
server to a network for systems-management information control.
Systems-management Ethernet activity LED:
When this LED is flashing, it
indicates that the server is transmitting to or receiving signals from the network for
systems-management information control that is connected to the
systems-management Ethernet port.
Video connector:
Connect a monitor to this connector.
Keyboard connector:
Connect a PS/2 keyboard to this connector.
Power supply status LED:
When the power supply status LED is green (lit or
flashing), it indicates that sufficient ac power is coming into the power supply
through the power cord and that the power supply is functional. When the power
supply status LED is amber (lit or flashing), it indicates a problem with the power
supply. If the LED is amber, see “Power supply LEDs” on page 108.
Server power features
When the server is connected to a power source but is not turned on, the operating
system does not run, and all core logic except for the service processor (the
baseboard management controller) is shut down; however, the server can respond
to requests from the service processor, such as a remote request to turn on the
server. The power-on LED is lit to indicate that the server is connected to power but
is not turned on.
Turning on the server
Approximately 5 seconds after the server is connected to power, the power-control
button becomes active, and one or more fans might start running to provide cooling
while the server is connected to power. You can turn on the server and start the
operating system 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 server is turned on, the server 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 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
When you turn off the server and leave it connected to power, the server can
respond to requests from the service processor, such as a remote request to turn
on the server. While the server remains connected to 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.
