Video connector
Connect a monitor to this connector.
Note: When attaching a monitor to the equipment, you must use the
designated monitor cable and any interference suppression devices
supplied with the monitor.
USB connectors
Connect USB devices to these connectors.
Ethernet connector
Use either of these connectors to connect the server to a network. When
you use the Ethernet 0 connector, the network can be shared with the
IMM2 through a single network cable.
Ethernet transmit/receive activity LED
This LED is on the Ethernet connector. When this LED is lit, it indicates that
there is activity between the server and the network.
Ethernet link status LED
This LED is on the Ethernet connector. When this LED is lit, it indicates that
there is an active connection on the Ethernet port.
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 is shut down; however, the server can respond to requests
to IMM2, 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
Note: Approximately 1 to 3 minutes after the server is connected to ac power, the
power-control button becomes active after the power-on LED flashes slowly.
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 peripheral component interconnect (PCI) devices.
Turning off the server
When you turn off the server and leave it connected to ac power, the server can
respond to requests to IMM2, 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.
