AC power LED: This green LED provides status information about the power
supply. During typical operation, both the ac and dc power LEDs are lit. For any
other combination of LEDs, see “Light path diagnostics” on page 93.
Power-cord connector: Connect the power cord to this connector.
Ethernet Activity LED: This LED is on the Ethernet connector. When it flashes, it
indicates that data is being transmitted or received between the server and the
network device that is connected to the connector. The flashing frequency is
proportional to the amount of traffic on the network link.
ASM: Use this connector to connect the server to an Advanced System
Management (ASM) network.
Ethernet link status LED: This LED is on the Ethernet connector. When this LED
is lit, there is an active connection on the Ethernet port.
Remote Supervisor Adapter II SlimLine Ethernet: Use this connector to connect
the server to an optional Remote Supervisor Adapter II SlimLine installed in another
server. This connector is enabled when the Remote Supervisor II SlimLine option is
installed.
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 service processor is
shut down; however, the server can respond to requests from the service processor
(also called the baseboard management controller), 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
Approximately 20 seconds after the server is connected to ac power, the
power-control button becomes active, one or more fans might start running, and 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 the server is connected to an Advanced System Management interconnect
network that contains at least one server with an optional Remote Supervisor
Adapter installed, the server can be turned on from the Remote Supervisor
Adapter user interface.
v
If your operating system supports the systems-management software for an
optional Remote Supervisor Adapter, the systems-management software can turn
on the server.
v If your operating system supports the Wake on LAN
®
feature, the Wake on LAN
feature can turn on the server.
